Description
[0001] The present invention relates to the field of textiles for
technical use, or technical fabrics, i.e. textile or woven
materials for which the choice of the textile materials and/or of
the weaving mode is principally made according to or guided by
certain technical or practical functions, properties or
characteristics of the fabric obtained.
[0002] More particularly, the invention relates to technical
fabrics comprising technical threads, of simple or complex
construction, themselves having one or more technical features
chosen for a specific application or applications of the technical
fabric obtained by weaving of the latter.
[0003] As is well known to the person skilled in the trade,
conventionally, any technical fabric does however remain a fabric,
i.e. an assembly, intertwining or interlacing of threads, which are
for example rectilinear, i.e. warp and weft, essentially in a
single plane, in at least two dimensions or directions, i.e. warp
and weft; the present invention not having the intention of
excluding technical fibres, called 3D fibres, i.e. which have a
certain thickness. Such a technical fabric can moreover
conventionally be defined, in addition to its intrinsic
characteristics, by the nature of the threads composing it, the
construction, structure, or elementary weaving pattern, able to
have a schematic or graphic representation or definition, which is
repeated periodically in the direction of the warp and/or the
direction of the weft. It is this elementary pattern conventionally
defined by the weave (including the type, repeat, or pace),
possibly the step number, the density of the warp and weft threads,
or thread count, and/or any other relevant weaving parameters, such
as the transparency, which enables the person skilled in the trade
to choose the loom required for the weaving and to prepare it so as
to be able to obtain, in a single weaving operation, any part of
the technical fabric the width of which will correspond, give or
take the selvedges, to that of the passage of the weft threads.
[0004] Consequently, conventionally, any part of a technical fabric
or any technical fabric presents an ordered monolithic, and
therefore homogenous, structure or construction, from one end of
the warp to the other, and/or from one selvedge to the other in the
direction of the weft, as it repeats the same pattern or the same
elementary weaving construction.
[0005] Assuming it to be "technical" in the sense defined above,
this is exactly what the document WO 2013/103 363 describes and
shows, in particular with reference to its FIG. 5. This document
describes various fabrics, of mesh type, i.e. presenting a large
transparency but remaining conventional or traditional in their
construction or structure in that they repeat the same weaving
pattern in the direction of the warp and/or of the weft. Thus,
considering paragraph 0086 of the description of WO 2013/103 363,
in combination with FIGS. 1 and 5, this document describes a fabric
of mesh type assembling high tensile strength warp threads (made
from Nylon.RTM. for example) with non-high tensile strength weft
threads (made from polyester for example), and repeating the same
elementary weaving pattern, i.e. a pattern of plaid type.
[0006] The present invention is now presented and explained in the
context of manufacture or production of various worked or
manufactured articles or products, such as certain articles of
footwear, for example footwear suitable for the pursuit of a sport,
in particular a racket sport. But this context chosen to illustrate
the various and varied possibilities and applications of the
present invention should naturally not be construed to limit the
interpretation and scope of the claims set out hereunder.
[0007] Today, as shown by WO 2013/103 363, different worked or
manufactured articles or products, such as footwear suitable for
the pursuit of a the sport, for example a racket sport, comprise
one or more parts, items or components made from flexible
material(s) and of small thickness, such as the shoe upper. These
parts or items are functional in that, respectively in different
areas of the upper and/or of the shoe, they have to provide one or
more respectively different technical or practical performances,
such as an abrasion resistance, breathability, support,
flexibility, etc., and possibly an aesthetic aspect.
[0008] In general, for any one part, such as the upper of sports
footwear, the technical performances expected or obtained differ
from one area to another and/or, for the same technical
performance, have respectively different values depending on the
areas concerned.
[0009] As is not indicated by WO 2013/103 636, taking the example
of racket sport footwear and considering the left or right foot,
the upper has to perform support of the foot, more or less on the
left and right sides, and in the centre, and remain flexible at the
front of the foot and in the centre along the axis of the shoe.
[0010] To conciliate these differentiated technical/practical
requirements depending on the areas of a specific part involved,
for example a sports shoe upper, the only solution used at the
present time essentially consists in assembling, i.e. joining
and/or superposing different pieces, for example by stitching or
sticking, previously cut out from respectively different materials,
for example flexible fabric and strong fabric; each of these pieces
performing, in the area where it is arranged on the part obtained
by assembly, approximately a single function, for example support
of the foot on both sides in the case of a racket sport shoe.
[0011] From the industrial manufacturing standpoint, in order to
conciliate these differentiated technical/practical requirements
according to the areas of the part involved, it is therefore
compulsory to perform or obtain an assembly of a multiplicity of
more or less mono-functional pieces, previously obtained, for
example cut out, from flexible materials of small thickness which
are very different from one another, for example leather, fabric,
or plastic material in sheet form.
[0012] This technical and industrial approach admittedly enables a
part to be obtained, for example a footwear upper, with
differentiated properties or characteristics according to the areas
of the latter which are considered, but obviously at the cost of a
complexity both of design and of manufacture/production.
[0013] Indeed, in addition to the fact that different materials are
implemented for the above-mentioned purposes, assembly can only be
performed in practice by manual operations such as stitching or
sticking, and hardly lends itself to automation for mass-produced
articles, such as sport shoes. Furthermore, such an assembly,
however well it is performed, generates lines of weakness or of
lesser strength, precisely along the joining lines between the
assembled pieces.
[0014] This is what the document WO 2013/103 363 shows, for example
by reference to the execution mode according to FIGS. 20A to 20C.
When particular properties have to be provided in certain areas of
the shoe, for example to enhance the liaison of the shoe with the
foot, the fabric forming the upper is lined inside and therefore
assembled with different strips and/or an intermediate layer.
[0015] Consequently, when different properties or characteristics
have to be provided in the finished flexible part, such as a shoe
upper, depending on the areas of said part involved, the state of
the art, and also the document WO 2013/103 363 (which essentially
describes a shoe intended for decorative or fashion purposes) only
disclose assembly solutions, on the surface and/or in-depth, with
different parts or components of the fabric constituting the part,
added-on at the appropriate locations of the latter.
[0016] Consequently, according to the state of the art, of which WO
2013/103 363 forms a part, different functions or properties are
not able to be differentiated and assigned in any one finished
flexible part, made from fabric, excepting any appropriate and
localised assembly of parts added onto the fabric.
[0017] The purpose of the present invention is to remedy the
shortcomings identified in the foregoing.
[0018] An object of the present invention is to provide a technical
fabric, considered as a semi-product, or more exactly a
pre-product, or direct precursor of a textile part, itself
essential for manufacturing, obtaining, or producing an article, or
a finished product, for example a sports footwear upper.
[0019] An object of the present invention is to provide such a
technical fabric, defined on a case by case basis, from the
above-mentioned textile part, analysed and considered in situ, i.e.
in the finished product in which it is integrated or of which it
forms a part, once said product has been manufactured.
[0020] An object of the present invention is to provide such a
technical fabric defined from its technical or practical properties
or characteristics, differentiated according to the areas of the
textile part involved, according to the use, usage, or properties
required for the article to which the textile part belongs after
manufacturing.
[0021] An object of the present invention is to provide a technical
fabric designed and obtained from the functions and properties
differentiated by design or according to the use of the textile
part and/or of the finished part in which the textile part is
integrated.
[0022] It is a further object of the present invention to obtain a
multifunctional flexible part, for example a footwear upper,
breaking away from the present-day design and industrial practice,
including that described by WO 2013/103 363.
[0023] An object of the present invention is to obtain a
multifunctional flexible part of the technical textile type, of
small thickness, able to be worked three-dimensionally, or
formable, so as to obtain a finished article or product either
directly or indirectly, in particular with other components.
[0024] More precisely, the object of the invention is to achieve a
single multifunctional part, or mono-part, as opposed, for the same
purposes or for the same objective, to multiple parts, all and each
of which are monofunctional, assembled to one another.
[0025] It is a further object of the invention to provide a
monolithic or monoblock flexible part made from technical fabric,
having a single thickness or a variable thickness, but which is
multifunctional, in the sense where different individualised areas
of said part present technical or practical
properties/characteristics respectively different from one discrete
area to another.
[0026] What is meant by "monolithic" or "monoblock" is that the
technical fabric according to the invention constitutes a single
woven part as obtained in a single weaving operation.
[0027] In general manner, the present invention is characterized in
that: [0028] (a) depending on the use or the destination of the
finished article or product, in the composition of which the
multifunctional flexible part is integrated, and in particular the
stresses to which said article is subjected, a multiplicity of
functional areas to which functions, properties/characteristics
respectively different from one area to the other are assigned are
defined and marked on a template of the flat flexible part; [0029]
This step constitutes the "mapping" step according to the invention
in the sense where, in a suitable coordinates system, in general
orthogonal (weft perpendicular to the warp), considering the
weaving which will be subsequently involved, it enables areas of
the finished article or product to be differentiated in the latter,
but on the multifunctional flexible part, according to the required
local functions, properties, or characteristics. These areas will
then be delineated, in shape and size, and localised in the
selected coordinates system, itself in general marked or "adjusted"
according to the finished article or product. [0030] To take the
example of a footwear article, the chosen orthogonal coordinates
system will be adjusted to that of the left or right shoe, and in
particular its axis of asymmetry, which will preferentially
correspond to the axis of the weft of the technical fabric in
question in the following. [0031] In this orthogonal coordinates
system, different areas will be differentiated according to the
functions, properties or characteristics which are locally of
importance for use of the shoe, for example: [0032] abrasion
resistance at the front of the foot, [0033] support of the foot, in
the middle, on the left and on the right of the shoe, [0034]
breathability in the middle of the foot, [0035] flexibility,
deformability at other places, [0036] etc. [0037] These areas
mapped in this way then serve the purpose of constructing the
technical fabric according to step (b). [0038] (b) A monolithic or
monoblock technical fabric is constructed, but which is
heterogeneous, as it is multisector, i.e. comprising a multiplicity
of discrete textile sectors, i.e. of individualised items of
fabrics, and therefore of respectively different elementary
constructions by at least one of the following parameters: [0039]
the weave (comprising for example the type, and for repeat, and/or
pace, and/or step number, etc.), and/or the density of the
assembled warp threads and/or weft threads, or thread count, [0040]
the nature, in particular chemical, and/or the intrinsic
construction of the threads, and/or their respective sizes, [0041]
the processing of the threads before and/or after their assembly,
[0042] the textile sectors being defined, or this or these
parameters being chosen in relation with said sectors so that on
the one hand these sectors correspond to the areas defined on the
template in step (a), which can be contained in the different
textile sectors respectively, and on the other hand the
properties/characteristics of the different sectors are those
identified or chosen for the different areas defined in step (a)
respectively; [0043] (c) in conformity with the construction chosen
according to (b), a suitable weaving loom is selected and prepared.
With the latter, the constructed fabric is woven according to step
(b) to obtain directly, i.e. in a single weaving operation, as a
semi-finished product, a single multisector fabric part; [0044] (d)
cutting means of the multisector fabric are available arranged to
flat cut the multifunctional flexible part in the fabric; these
cutting means are identifiable with respect to the drawing of the
textile sectors on the width of the multisector fabric so that the
areas defined in step (a) are individually and respectively
contained in the different textile sectors defined in step (b);
[0045] (e) with the cutting means positioned and identified with
respect to the multisector technical fabric part, the monoblock or
monolithic but multifunctional flexible part is cut and obtained
directly.
[0046] The present invention described in the foregoing in general
manner achieves a new technical fabric, i.e. obtained directly in
one and the same weaving operation. This fabric is characterized in
that it has in general manner a monolithic or monoblock
construction or structure, as opposed to a patched or stacked
structure, i.e. obtained by assembly, for example stitching, of
different or identical pieces. Nevertheless, according to the
invention, this monolithic structure is heterogeneous as far as its
constitution is concerned, i.e. it comprises a multiplicity of
textile sectors, i.e. woven, discrete, i.e. of individualised items
of fabrics, the ordered construction of which differs from one
textile sector to another according to the direction of the warp
and/or that of the weft. Furthermore, according to the present
invention, these textile or discrete woven sectors differ from one
another, for example two by two, adjacent or separated from one
another, by at least one of the following parameters: [0047] the
weave (including for example the type, and/or repeat, and/or pace,
and/or step number, etc.), and/or the density, or thread count, of
the assembled, intertwined, or interlaced warp threads and/or weft
threads; [0048] the nature, in particular physical, of said
threads, and/or their intrinsic construction; [0049] the processing
of said threads before and/or after their assembly.
[0050] So that the technical or practical properties, functions, or
characteristics of the different textile sectors are respectively
different, for example considered two by two, in adjacent manner or
separated from one another, in particular in the direction of the
warp and/or that of the weft.
[0051] Considered on the scale or at the level of a single textile
sector, these same technical or practical properties, functions, or
characteristics can be identical, similar, homogeneous, or
interdependent from one point to another of the textile sector
considered.
[0052] A technical fabric according to the present invention is
essentially formed by straight threads and/or mixed line threads,
in so far as it is the woven structure that essentially gives it
its consistence, in particular its quasi-indeformability, which
does not exclude that: [0053] this same fabric can comprise knitted
parts, of limited extension, added onto or integrated in the
structure of the fabric; [0054] certain textile sectors can be
overwoven, or assembled, in particular lined with other textile
parts, or others, added-on during the weaving operation or
subsequently to the latter, for example for aesthetic purposes.
[0055] Each textile sector, i.e. each individualised fabric item,
has any appropriate shape and dimensions suitable for
circumscribing the shape and dimensions of the area of the
multifunctional flexible part which has to be contained in and be
cut in said sector of the technical fabric. This shape is in
general quadrangular, square or rectangular when a weaving loom
other than a Jacquard is implemented to weave a fabric part
according to the invention.
[0056] A part or a technical fabric according to the invention can
be constructed so that one or more identical or different templates
are repeated on the fabric along the axis or in the direction of
the warp and/or along the axis or in the direction of the weft,
each template being constituted or constructed according to the
invention, i.e. being on its own a technical fabric of monolithic
or monoblock but heterogeneous, structure, as it comprises a
multiplicity of discrete textile sectors the ordered weaved
construction of which differs from one textile sector to
another.
[0057] A technical fabric according to the invention can comprise
one or more textile sectors having a three-dimensional, i.e. 3D,
structure/construction or presenting a certain thickness, whereas
the others are two-dimensional or two-directional, or 2D, all these
sectors remaining obtained by a single weaving operation.
[0058] A technical fabric according to the invention can be
obtained with any suitable weaving loom comprising a number of
frames adapted to the complexity, including the number of different
textile sectors, of said fabric, for example a rapier weaving loom
comprising 16 frames or blades.
[0059] When a Jacquard loom is implemented, individual control of
the warp threads enables one or more textile sectors of a shape
other than rectangular to be obtained with a total freedom as to
the shape of the woven textile sectors according to the present
invention.
[0060] A technical fabric according to the present invention
therefore makes it possible to group, and above all to zone or
localise, on a single flexible part, such as a shoe upper, all the
properties/characteristics required or designed with respect to the
finished article product in which said part is integrated.
[0061] A technical fabric according to the invention therefore not
only enables weight to be saved, but also enables the manpower
required for the purposes of manufacturing the finished product to
be limited to the strict minimum, or even enables automated
production of the latter to be considered.
[0062] Due to its intrinsic features set out in the foregoing and
exemplified hereafter, a technical fabric according to the present
invention has a multitude of applications, among which: [0063]
obtaining footwear articles, in particular sport shoes, [0064]
luggage, [0065] gloves, [0066] individual protection equipment,
[0067] medical devices such as parietal prostheses.
[0068] The present invention concerns any use or employment of a
template, and more generally of a technical fabric as defined in
the foregoing, to obtain directly by flat cutting in the fabric at
least one flexible construction part that is monolithic or
monoblock, but heterogeneous, as it comprises a multiplicity of
discrete textile areas having respectively different functions,
properties/characteristics from one area to another; each discrete
textile area being by definition and individualised fabric part,
the ordered construction of which differs from one textile area to
another, in the direction of the warp and/or of the weft, but at
least one of the following parameters: [0069] the weave and/or the
density of the assembled warp threads and/or of the weft threads;
[0070] the nature, in particular chemical, of said threads, and/or
their intrinsic construction; [0071] processing of said threads
before and/or after their assembly.
[0072] For this purpose, if cutting means are available, for
example by laser or punch, the latter can be positioned and
referenced solely with respect to the design or arrangement of the
textile sectors on the technical fabric so that the functional
areas are individually and respectively contained in the different
textile sectors of the fabric.
[0073] The present invention relates to a monolithic or monoblock,
but heterogeneous, flexible part able to be obtained by the use or
implementation of a template, relates more generally to an
identical technical fabric to the one defined in the foregoing, and
relates in particular to a flexible part comprising a multiplicity
of discrete textile areas, also as defined in the foregoing.
[0074] The present invention further relates to a manufacturing
method of a finished article or product, comprising a flexible part
made from multisectored technical fabric according to the
invention, defined and described in the foregoing. By means of the
invention, it is this flexible part which directly gives technical
or practical properties/characteristics differing from one discrete
area or part to another of said article, comprising said flexible
part.
[0075] To manufacture one such article, it is possible to: [0076]
start from or procure a flexible part as defined in the foregoing;
[0077] shape said flexible part; [0078] and, if applicable,
assemble said shaped flexible part with one or more other
components of the same article to obtain a finished article or
product.
[0079] Due to the present invention, it is not necessary to locate,
orient or control the orientation of the flexible part with respect
to the other components or parts with which it is assembled or
constructed to obtain the finished product or article.
[0080] Such a finished article is for example a footwear article,
in particular a sport shoe, for example a shoe for the pursuit of a
racket sport; and, in this case, the flexible part defined or
described above directly constitutes the essential part of the
footwear article upper.
[0081] The present invention therefore relates to a footwear
article, in particular a sport shoe, for example a shoe for the
pursuit of a racket sport, the upper of which is formed by or
comprises a technical fabric, of monolithic or monoblock, but
heterogeneous, construction or structure, as it comprises a
multiplicity of discrete textile sectors each constituting an
individualised fabric part the ordered construction which differs
from one textile sector to another, in the direction of the warp
and/or that of the weft, by at least one of the following
parameters: [0082] the weave (including for example the type,
and/or the repeat, and/or the step number, and/or the pace, etc.),
and/or the density of the assembled warp threads and/or weft
threads, [0083] the nature, in particular chemical, of said
threads, and/or their intrinsic construction, [0084] the processing
of said threads before and/or after manufacturing of the footwear
article, so that the technical or practical properties or
characteristics of the upper differ from one discrete area to
another of the latter.
[0085] A footwear article produced according to the present
invention enables good dynamic performances, or others, of the shoe
to be conciliated with a weight which remains light, while at the
same time ensuring effective support of the foot.
[0086] When the terms "multi" or "several" are used in the present
description in relation with the areas of the flexible part of the
manufactured article, or the sectors of the technical fabric
according to the invention, an integer at least equal to two, and
in particular at least equal to three, has to be considered.
[0087] The term "article" or "product" refers to an object, for
example a manufactured object, ready-to-use or for a given use,
such as a footwear article, for example a sport shoe.
[0088] The term "fabric" refers to a half-product, semi-product, or
pre-product, which itself has to be worked or fashioned to obtain a
component such as a flexible part, or directly a finished article
or product.
[0089] What is meant by "thread" is, as understood in the textile
industry, any single-dimensional strand having a length larger than
its width and/or thickness, comprising filaments, spun threads,
fibers, continuous or discontinuous threads, cables, or others,
constituted by various materials, in general technical materials,
i.e. presenting functional or improved
properties/characteristics.
[0090] For example, warp threads and/or weft threads of the
technical fabric according to the invention, in particular of all
or part of the textile sectors, each comprise at least one
mechanically strong material, for example a high tenacity polyamide
(PA HT), and/or a para-aramid, and/or an abrasion-resistant
material, for example a polyamide, and may be coated for example
with a polyurethane which may if applicable be charged with
ceramic.
[0091] Preferentially, the threads of the fabric, warp threads
and/or weft threads, according to the invention have essentially
the same size, expressed for example in DTex.
[0092] According to the present invention, the warp threads and/or
weft threads individually have a simple construction, for example a
mono-filament, or a complex construction, for example by assembly
by portion of several elementary threads, or by reaming of one or
more threads around a strand core.
[0093] The term "flexible part" refers to any part as obtained by
cutting, by any suitable means (for example by punching, or laser
cutting), marked or referenced with respect to the drawing,
generated or constituted by arrangement of different textile
sectors, present on the technical fabric according to the
invention. This flexible part comprises a multiplicity of textile
areas resulting directly from the registered cutting of the
multisector fabric, these areas having respectively different
functions, properties or characteristics which are exactly those of
the different sectors of the technical fabric in which the cuttings
of the different areas are respectively contained. This flexible
part therefore ultimately has the same construction, and therefore
the same consistence, as those of the technical fabric used for
cutting, and can be shaped directly, without any other particular
measurement, to achieve the required finished article or
product.
[0094] Even if their functions, properties, and characteristics are
substantially the same, for the sake of clarity of the following
explanations, the term "sector" will be reserved for the technical
fabric, and the term "area" for the multifunctional flexible part,
or for the flexible part of the article or product obtained with
said part. According to the present invention, an area can result
from the cut contained in a corresponding sector of the technical
fabric.
[0095] According to a preferred, but non-restrictive, embodiment of
execution of the invention, the fabric insert is constructed in
such a way that one or more identical or different rectangular
templates, themselves multisector as defined in the foregoing, are
repeated on the fabric in the direction of the warp and/or the
direction of the weft.
[0096] Each template is designed to be cut to directly obtain at
least one multifunctional flexible part according to the
invention.
[0097] In the case of a footwear article, for example a sport shoe,
this industrial modality makes it possible to obtain by cutting in
a single technical fabric part, the two uppers (left and right
feet) not only of one pair of shoes, but also of pairs of
difference sizes.
[0098] In certain cases, in particular to give a certain rigidity
in certain areas of the flexible part, or of the finished article
or product, for example at the level of the backstrap of a shoe,
after weaving, at least one sector of the fabric or at least one
area of the flexible part comprises thermofusible warp threads
and/or weft threads so as to be suitable for subsequent heat
treatment to link and fix the threads to one another, for example
to form and/or rigidify the flexible part.
[0099] The present invention relates to a technical fabric able to
be obtained by chaining of the steps according to the invention
defined in the foregoing, i.e. (a) (mapping), (b) (construction of
the technical fabric), and (c) weaving of the fabric in a single
weaving operation.
[0100] A technical fabric according to the invention, considered as
a semi-product, half-product, or pre-product, presents the aspect
of a "patchwork" (but without stitching or other links) or "mosaic"
of sectors, for example of rectangular shape, respectively
differing according to at least one of the following parameters:
[0101] the weave (including for example the type, and/or the
repeat, step number, pace, etc.), and/or the density of the
threads, [0102] the nature, in particular chemical, and/or the
construction of the threads, [0103] the processing of the threads
before and/or after their assembly.
[0104] These multiple textile or woven sectors respectively
different in the direction of the weft and/or the direction of the
warp consequently present respectively different functions,
properties, or characteristics from one sector to another. These
respectively different properties/characteristics are the direct
consequence of ordered woven constructions which respectively
differ according to the sectors of the fabric. They will then be
directly those of the different areas respectively of the flexible
part obtained directly by registered cutting of the technical
fabric according to the invention, for example in the template
provided for this purpose on the latter, as indicated in the
foregoing.
[0105] Considering a technical fabric as defined in the foregoing,
the invention enables the latter to be functionalised at will, or
on a case by case basis, according to the warp and/or weft, in
correspondence with the mapping selected or designed for the
finished article or product obtained with a technical fabric
according to the invention. The registered cut will exactly
reproduce the mapping thus selected.
[0106] Furthermore, the invention totally circumvents a possible
symmetry of the finished article product in which the flexible part
is integrated, such as a pair of shoes, for which, for any one
shoe, the left side differs from the right side and the right shoe
differs from the left shoe. In such a case, according to the
invention, a single fabric part can be constructed comprising two
templates side by side or one above the other, one for the left
foot and the other for the right foot, differing from one another
by the asymmetric construction of these same textile sectors, or
"mirror" textile sectors, i.e. which correspond by 180.degree.
rotation around an axis in the lap or the plane of the fabric.
[0107] Such a result cannot be obtained by the method according to
WO 2013/103 363, according to which, whether the left foot or the
right foot is involved, the flexible part or upper obtained, in
this instance the fabric of the upper, has exactly the same
construction in the warp and/or weft of the fabric.
[0108] According to the invention, the symmetry of a flexible part
no longer opposes differentiated zoning of the latter in a
single-layer technical fabric, in the same way as two flexible
parts identical as far as their zoning is concerned but not able to
be superposed, can be obtained from one and the same part or width
of single-layer technical fabric.
[0109] The present invention relates to a manufacturing method of a
finished article or product, integrating, comprising, or
constituted by a multifunctional flexible part, which either
completely or partially gives said finished article or product the
technical and practical functions, properties/characteristics which
are its own, i.e. different properties/characteristics from one
discrete area to another of said part.
[0110] According to this method: [0111] the starting point is a
monoblock or monolithic, multifunctional flexible part, as defined
previously; [0112] said flexible part is shaped or formed; [0113]
if applicable, the shaped flexible part is assembled with one or
more other components of said article, to obtain a finished article
or product.
[0114] Consequently, the invention relates to any article or
product obtained or able to be obtained by a method as defined in
the foregoing. Such an article can comprise one or more flexible
parts according to the present invention, i.e. each being monoblock
or monolithic, but heterogeneous, as they are multifunctional, or
comprising a multiplicity of respectively different textile
sectors.
[0115] To serve as an example of such an article, a footwear
article will be considered in the following, and more particularly
a sport shoe, for example a shoe for the pursuit of a racket sport.
In such a case, the upper is directly a multifunctional flexible
part obtained as defined in the foregoing.
[0116] The present invention is now described according to two
exemplary embodiments for obtaining the upper (multifunctional
flexible part), and then a shoe for racket sports, in this case
tennis, with reference to the following figures, i.e.:
[0117] FIG. 1, which represents, in a flat view, the asymmetric
upper 1 of a tennis shoe, the left foot, showing lacing holes 2 on
each side of an axial gullet 30 (cf. axis of asymmetry 20), for a
lace to pass through;
[0118] FIGS. 2 and 3 respectively represent a first and second
mappings, or templates 41 and 42, respectively of the same upper
represented in FIG. 1;
[0119] making abstraction of the cutting line 50 and of the hatched
cut part 51, FIGS. 4 and 5 present two templates 61 and 62 drawn or
plotted in respectively different technical fabrics according to
the invention, in a warp(6)/weft(5) system of the fabric to which
they belong, constructed according to the mappings or templates 41
and 42 of FIGS. 2 and 3 respectively;
[0120] FIG. 6 schematically represents, in a flat view, a technical
fabric part 3 comprising templates 4 repeated in the direction of
the weft 5, and also in the direction of the warp 6, each template
having for example a textile construction according to FIG. 4
explained with reference to Example 1, or according to FIG. 5
explained with reference to Example 2;
[0121] FIG. 7 schematically represents, in cross-section, a
footwear article 7, for example a sport shoe, more particularly a
tennis shoe, comprising or integrating a previously formed
multifunctional flexible part 1 constituting the upper of the shoe,
then assembled by sticking or thermo-adhesion with a sole 8.
[0122] According to FIG. 1, the upper 1 of a sport shoe is
represented in a flat view, the shoe in this instance being a
tennis shoe, for example represented schematically in cross-section
in FIG. 7, from which the present invention will now be explained
in detail.
[0123] Conventionally, this upper is a flexible part, formed by
assembly in adjacent and/or superposed manner, by sticking and/or
stitching, of different pieces made from different flexible
materials of small thickness, for example leather, fabric, or
plastic material in sheet form, etc. A detailed explanation will
not be given here of this assembly, which is represented in FIG. 1
in simplified manner by different drawings inside the line 71
delineating the upper of the shoe represented in flat manner.
[0124] With reference to the axis of asymmetry 20, for example
considering the direction from the front to the back of the shoe,
and/or the inside/outside direction of the shoe, from left to right
according to FIG. 1, it is obviously possible to locate or
position, on a template 41 or 42, different areas of the upper
moreover defined as far as shape and dimensions are concerned, in
this instance rectangular, to which different functions are
assigned dependent on or related to the use or the performances of
the shoe, or for which the shoe manufacturer/designer requires
different technical or practical properties or characteristics
differentiated according to the areas involved.
[0125] What is meant by "axis of asymmetry", when a shoe is
involved, is the intersection of the horizontal plane with the
sagittal plane of a foot, on each side of which, as shown by FIG.
1, the two halves of the shoe receiving said foot are respectively
different, at least as far as their respective shapes are
concerned.
[0126] Among these properties, the following can be cited for
example purposes: [0127] the abrasion resistance which, in certain
areas, has to be high due to the possible friction of the upper of
the shoe with the ground, [0128] support of the foot at certain
places of the upper, which requires the flexible material of the
upper to have a certain tenacity or a small elongation under
tension, [0129] a certain permeability, or transparency, enabling
the foot to "breathe", or breathability, [0130] at certain places,
a deformability of the flexible part or upper, for the comfort of
the foot, [0131] and furthermore at other places, the technical
possibility of being thermoformed, for example at the location of
the counter of the upper and therefore of the shoe.
[0132] The person skilled in the trade i.e. the sport shoe
designer/manufacturer, is therefore led to differentiate the
properties of the upper 1 according to the functional areas of the
latter, depending on or in correspondence with the use of the shoe,
and in particular the required performances. This differentiated
approach of the tennis shoe for example will lead this
designer/manufacturer, for the same shoe upper, to different
"zonings", in terms of properties and characteristics, depending on
the models proposed or made available to the user.
[0133] According to FIGS. 2 and 3, from the template of the upper
represented in FIG. 1, and marked as previously indicated, i.e.
from the axis of asymmetry 20, from the front to the back of the
shoe, taking account of the stresses to which the latter is
subjected, two respectively different zonings can be established or
chosen according to the templates 41 and 42 of FIGS. 2 and 3
respectively.
[0134] In a first example according to FIG. 2, the following can be
seen, in a coordinates system formed by four lines parallel to the
axis of asymmetry 20, i.e. the two straight edges of the template,
i.e. 23 on the left and 24 on the right, and two intermediate lines
21 and 22, on the right side of the template, and from left to
right: [0135] two first adjacent areas A1 (between the lines 23 and
21) and A2 (between the lines 21 and 22), respectively on the two
sides of the line 21, together forming a weft strip A, which will
each have to resist abrasion; [0136] two second adjacent areas B1
(between the lines 23 and 21) and B1 (between the lines 21 and 22),
respectively on the two sides of the line 21, together forming a
weft strip B, which will both have to be flexible, permeable and
breathing, while at the same time performing support of the foot;
[0137] a third rectangular area C1 (between the lines 23 and 21)
which will have to contribute to support of the foot, a fourth
rectangular area C2 (between the lines 21 and 22) which will
particularly have to resist abrasion, and again a third area C1
will have to contribute to support of the foot; the areas C1/C2/C1
together forming a weft strip C; [0138] a fifth area D1 (between
the lines 23 and 21), another fifth area D2 (between the lines 21
and 22), and again a fifth area D1, which will each have to perform
support of the foot and facilitate breathing of the latter; the
areas D1, D2 and D3 together forming a weft strip D; [0139] a sixth
area E1 (between the lines 23 and 21), another sixth area E2
(between the lines 21 and 22), and again a sixth area E1, which
will each have to perform support of the foot, while enabling
thermoforming of the upper; the areas E1,E2,E1 together forming a
weft strip E.
[0140] In the zoning defined above, by convention, the areas for
which identical or similar properties are required are designated
by the same reference letter and the same numeral; for example, C1
refers to an area, called third area, which, on each side of an
area C2, will have to contribute to support of the foot. And the
upper-case letters A to E, from the front to the back of the shoe,
refer to different weft strips, staged from the front to the back
of the shoe, each comprising a series of areas as set out in the
foregoing; for example, A refers to a narrow strip, at the front of
the shoe, which will have to resist abrasion, whereas E refers to a
broad strip, at the back of the shoe, which will have to perform
support of the foot while enabling thermoforming of the upper.
[0141] In a different manner, according to a second example, with
reference to the template 42 according to FIG. 3, another zoning of
the upper 1 of this same shoe is performed, which establishes,
again in the same coordinates system: [0142] two first rectangular
areas A1 and A2, respectively on the two sides of the axis of
asymmetry 20, which will both have to resist abrasion; [0143] two
second rectangular areas B1 and B2, respectively on the two sides
of the axis of asymmetry 20, which will both have to be flexible
and breathing, while performing support of the foot; [0144] two
third rectangular areas C1 and C2, respectively on the two sides of
the axis of asymmetry 20, which will both have to perform a first
support of the foot and ensure its breathing; [0145] two fourth
rectangular areas D1 and D2, respectively on the two sides of the
axis of asymmetry 20, which will both have to perform a second
support of the foot and ensure its breathing; [0146] two fifth
areas E1 and E2, respectively on the two sides of the axis of
asymmetry 20, which will both have to perform a third support of
the foot, with the possibility of thermoforming the upper.
[0147] It can be observed that the previously defined zonings
according to FIGS. 2 and 3 can differ from one another, essentially
by the fact that areas of different densities are arranged
differently in the width of the template 41 or 42. According to
FIG. 2, an over-densified area exists between the two lines 21 and
22, parallel to the axis of asymmetry 20, with two areas of
identical and normal density on each side of the latter. According
to FIG. 3, an area of normal density and an area of larger density,
with the same widthwise extension, are arranged on each side of the
axis of asymmetry 20.
[0148] From a template 41 or 42 zoned as in the foregoing, i.e.
according to the functional, technical, or practical choice or
choices, or the choice of performances of the designer/manufacturer
of the shoe, and therefore of the upper, a template is constructed
in the direction of the warp 6 and in the direction of the weft 5,
respectively 61 or 62, or a technical fabric part comprising the
latter, having a monolithic or monoblock, but heterogeneous
structure, as it results from the textile construction choices set
out in the following.
[0149] In practice: [0150] as shown in FIGS. 4 and 5, to construct
the technical fabrics respectively 31 and 32, two types of warping
are implemented respectively O.sub.1 and O.sub.2, differing from
one another by the density of the warp threads, the size, and/or
the construction, and/or the nature of said threads; according to
FIG. 4, the warping O.sub.1 is the same between the lines in the
direction of the warp 203 and 201, corresponding to the lines 23
and 21 of the template 41, and the lines 202 and 204 corresponding
to the lines 22 and 24 of the template 41, whereas a different
warping O.sub.2 is used between the lines in the direction of the
warp 201 and 202; according to FIG. 5, the warping O.sub.1 between
the warp lines 203 and 200 (corresponding to the axis of asymmetry
20 of the template 42) is different from the warping O.sub.2 used
between lines 200 and 204; [0151] as also shown by FIGS. 4 and 5,
to construct the technical fabrics 31 and 32, different
arrangements of the weft threads are implemented in the weft strips
(a) to (e) shown in each of FIGS. 4 and 5; these arrangements of
the weft threads, determined by frames arranged differently, differ
from one another by the density of the weft threads, the size,
and/or the construction, and/or the nature of said threads; [0152]
the template 61 or 62 of the technical fabric 31 or 32 can
correspond to the selected template 41 or 42, in shape and/or in
dimensions; [0153] the previous textile construction has the result
that the technical fabric obtained is divided into different
discrete, individualised, textile parts, or textile sectors
(a.sub.1 to d.sub.1; a.sub.2 to e.sub.2), that are identical in
shape and/or dimensions to the different template areas; textile
sectors which have been designed and constructed individually to
comply with the functional or technical specificities respectively
expected for the different areas (A.sub.1 to E.sub.1; A.sub.2 to
E.sub.2); [0154] for this purpose, not only the warp and/or weft
threads are differentiated, for example by the chemical nature
and/or their intrinsic technical characteristics, and/or their
construction, but above all, the differentiated construction, or
composite warping, of the warp threads, in the direction of the
weft, and also the different criss-crossing mode(s) of the weft
threads, in the direction of the warp, enable the different textile
sectors obtained on the template 61 or 62 of the technical fabric
to be achieved (in the warp/weft system) and to be varied at
will.
[0155] The person skilled in the trade, with any present-day
weaving loom, can thereby design and produce any templates or
sectored technical fabric parts, showed for example purposes in
FIGS. 4 and 5 respectively, the different textile sectors
referenced by a lower-case letter respectively corresponding to the
different areas referenced by an upper-case letter in FIGS. 2 and 3
respectively.
[0156] The two templates 61 and 62 represented in FIGS. 4 and 5
respectively belong to the two respectively different,
multi-sectored technical fabrics 31 and 32.
[0157] To construct these two different technical fabrics, i.e. 31
and 32, first of all threads are taken differing from one another
by their chemical nature and/or their construction, referenced CA,
CB, TA for the warp threads and TB, TC, TD for the weft threads in
Examples 1 and 2 below. Both the physical characteristics and the
chemical composition of these threads are set out in detail in
these examples.
[0158] The elementary or discrete textile sectors to be obtained by
a single weaving operation can then be differentiated by the choice
of the constructions or weavings used from one sector to the other,
as shown in Examples 1 and 2 ci-apres.
[0159] Finally, the density or thread count of the warp threads
and/or of the weft threads can be varied to respectively achieve
different textile or woven sectors, as also shown in Examples 1 and
2 below.
[0160] The fabrics according to Examples 1 and 2 below are obtained
by weaving with a rapier loom comprising sixteen frames.

[0172] With reference to FIG. 4, the distance 203/201 is 18 cm, the
distance between 201 and 202 is 7.5 cm, and the distance between
202 and 204 is 3.5 cm.

[0179] For example purposes, the textile sector (a.sub.1) having a
plain weaving differs from the textile sector (a.sub.2) having a
plain weaving by the construction of the warp threads, and from the
textile sector (b.sub.1) having a natte weaving by the construction
of the weft threads.

Strip d=128 TC Serge 2/2 (15 picks/cm) [0192] Strip e=108 TD (11

[0194] For example purposes, textile sector (a.sub.1) having a
plain weaving differs from textile sector (a.sub.2) having a plain
weaving by the construction of the warp threads, and from textile
sector (b.sub.1) having a natte weaving by the construction of the
weft threads.
[0195] As shown by FIGS. 4 and 5, for each fabric 31 or 32, the
strips a to e of fabric correspond to the areas A to E defined on
the template of the upper 1. And the properties/characteristics
conferred by the choices of textile construction made for these
different textile or woven sectors are those selected or required
for the different areas defined on the template of the upper 1.
[0196] To sum up, a technical fabric according to the state of the
art, including according to WO 2013/103 363, can be graphically
represented or defined by the single drawing or sketch of its
weaving, whereas the graphic representation or definition of a
technical fabric according to the present invention comprises a
multiplicity of separate and different drawings or sketches which
are those of the elementary constructions respectively of the
different textile sectors.
[0197] In practice, as shown by FIG. 6, a technical fabric 3 will
be constructed and woven in a single operation so as to repeat a
template 61 or 62 both in the direction of the weft 5 and/or in the
direction of the warp 6, presenting the sectored textile pattern or
drawing according to FIG. 4 (Example 1) or FIG. 5 (Example 2).
[0198] More exactly, a technical fabric part obtained, represented
schematically in FIG. 6, will comprise a first template 4
corresponding to a left foot, directed towards a first weft edge of
the part, and a second template 4 obtained by turning and rotation
through 180.degree. of the first template 4 around an axis of
symmetry parallel to the weft, corresponding to the right foot, but
directed towards the other weft edge of the same part.
[0199] A pair of uppers each corresponding to one and the same pair
of shoes can thus be subsequently obtained by the cuts specified in
the following in a technical fabric part according to the
invention.
[0200] Referring to a template 61 or 62 according to FIG. 4 or 5,
comprised in a part or width of a multisector technical fabric
according to the invention, and having cutting means (for example
punch cutting) available, it is possible to cut flat along the
closed cutting line 50 in the fabric and to directly obtain the
flexible, multifunctional cut part 51, or shoe upper 1, required
