Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of Taiwan Patent
Application No. 104220547, filed Dec. 22, 2015 at the Taiwan
Intellectual Property Office, the disclosure of which is
incorporated herein in its entirety by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present disclosure relates to a vamp with an embossed
pattern, more particularly to a vamp having an embossed pattern
which is formed by a manner of cold pressing.
[0004] 2. Description of the Related Art
[0005] While high technology industries such as the semiconductor
industry have rapidly developed, the textile industry has so far
generally remained traditional in its practices. The textile
industry faces strong competition and pressure to continuously
innovate and integrate new technologies in order to develop novel,
high value-added products. In recent years, textile products have
to perform well, be comfortable, include protection features and
appear aesthetically appealing and fashionable. As a result
functional fabrics have become a hot product in the textile
industry.
[0006] A conventional vamp made of fabric does not have the desired
physical characteristics, and in particular lacks structural
reinforcement. So during the manufacturing process, some reinforced
sheets (or films) are sewn on to reinforce the shoe's structure. On
the other hand, commercially available polyurethane (PU) vamp does
have the desired physical property of being structurally sturdy,
but has the drawback of poor breathability.
[0007] After much experience and study in the field, the inventor
of the present disclosure has developed and designed a vamp with an
embossed pattern that overcomes the aforementioned limitations of
conventional shoe build and design to provide present-day desired
features, while also improving on industrial practicability.
SUMMARY OF THE INVENTION
[0008] An objective of the present disclosure is to provide a vamp
with an embossed pattern, to overcome the aforementioned
limitations of conventional shoe build and design.
[0009] To achieve the objective, the present disclosure provides a
vamp with an embossed pattern, and the vamp includes plain cloth
and an embossed layer. The plain cloth is of breathable fabric
blended with hot-melt adhesive yarn. The embossed layer is formed
on the plain cloth by a cold press process performed with cold
press apparatus, and the embossed layer on the vamp serves as a
predetermined design pattern or as a structural reinforcement.
[0010] Preferably, the vamp further includes a colored layer formed
on the embossed layer or the plain cloth by a manner of digital
printing.
[0011] Preferably, the plain cloth is provided with a crop mark,
and the colored layer is formed in an area enclosed by the crop
mark.
[0012] Preferably, the plain cloth is provided with a crop mark,
and the vamp is formed by cropping the plain cloth along the crop
mark.
[0013] Preferably, the plain cloth can withstand a temperature
range from 150.degree. C. to 190.degree. C. in a process of forming
the embossed layer.
[0014] Preferably, in the process of forming the embossed layer,
the plain cloth is heated to a temperature below 190.degree. C. and
above 150.degree. C. with hot air generated from a hot blow drying
device, and the temperature of the hot air is in the range
100.degree. C. to 200.degree. C.
[0015] Preferably, the cold press apparatus is operated to cold
press on the plain cloth in a temperature range from 0.degree. C.
to 25.degree. C.
[0016] Preferably, the plain cloth is white cloth.
[0017] According to the aforementioned content, the vamp of the
present disclosure has at least one of advantages described
below.
[0018] First, during the formation of the vamp of the present
disclosure, the cold press process is performed on the breathable
plain cloth to melt the hot-melt adhesive yarn. The melted hot-melt
adhesive yarn then hardens to form the embossed layer. The embossed
layer may serve as the predetermined design pattern or the
structural reinforcement for the vamp, according to what physical
properties are desired for the breathable fabric vamp of the shoe
to be produced.
[0019] Second, during the formation of the vamp of the present
disclosure, the digital printing process is performed on the white
plain cloth to form the colored layer on the embossed layer or on
the plain layer. This is preferable to water-polluting methods of
conventional dying of the vamp.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0024] The following embodiments of the present invention are
herein described in detail with reference to the accompanying
drawings. These drawings show specific examples of the embodiments
of the present invention. It is to be understood that these
embodiments are exemplary implementations and are not to be
construed as limiting the scope of the present invention in any
way. Further modifications to the disclosed embodiments, as well as
other embodiments, are also intended to be included within the
scope of the appended claims. These embodiments are provided so
that this disclosure is thorough and complete, and fully conveys
the inventive concept to those skilled in the art. Regarding the
drawings, the relative proportions and ratios of elements in the
drawings may be exaggerated or diminished in size for the sake of
clarity and convenience. Such arbitrary proportions are only
illustrative and not limiting in any way. The same reference
numbers are used in the drawings and description to refer to the
same or like parts.
[0025] It is to be understood that, although the terms `first`,
`second`, `third`, and so on, may be used herein to describe
various elements, these elements should not be limited by these
terms. These terms are used only for the purpose of distinguishing
one component from another component. Thus, a first element
discussed herein could be termed a second element without altering
the description of the present invention. As used herein, the term
"or" includes any and all combinations of one or more of the
associated listed items.
[0026] The following refers to FIG. 1, which shows a schematic view
of a finished vamp with an embossed pattern in accordance with the
present disclosure. As shown in FIG. 1, a vamp 1 includes a plain
cloth 10 and an embossed layer 20. In an embodiment of the present
disclosure, the vamp 1 can further include a colored layer 30, and
the plain cloth 10 is implemented as breathable fabric blended with
hot-melt adhesive yarn. The embossed layer 20 may partially cover
the plain cloth 10 where necessary. The colored layer 30 is
disposed on the plain cloth 10, or on the embossed layer 20, or on
both the plain cloth 10 and the embossed layer 20.
[0027] The following refers to FIGS. 2 and 3, which respectively
show the first and second schematic views of the vamp of the
present disclosure. In FIG. 2, the embossed layer 20 is disposed on
the plain cloth 10. In FIG. 3, the embossed layer 20 and the
colored layer 30 are both disposed on the plain cloth 10.
[0028] In one embodiment, a step of dying the plain cloth 10 may be
omitted, such that the plain cloth 10 remains as a white cloth and
any further water pollution due to a dying process is avoided. The
plain cloth 10 is formed by weaving the hot-melt adhesive yarn
together with at least one other different kind of yarn by using a
knitting machine. The plain cloth 10 may be marked with a crop mark
11, so that after the embossed layer 20 or the embossed layer 20
and the colored layer 30 are applied to the plain cloth 10, the
processed cloth can be cropped along the crop mark 11 to form the
vamp 1. A cold press apparatus is used to press onto the plain
cloth 10, which causes the hot-melt adhesive yarn to melt and then
harden, and so forming the embossed layer 20 on the plain cloth 10.
The embossed layer has a 3D structure. The user may set a
predetermined stamp of a press plate of the cold press apparatus,
and then perform a cold press on a preset area of the plain cloth
10 where the embossed layer 20 is to be formed. The hot-melt
adhesive yarn within the area melts and then hardens, so as to form
the embossed layer 20 which partially covers a surface of the plain
cloth 10. In the above description, the embossed layer 20 partially
covers the surface of the plain cloth 10, and so during formation
of the embossed layer 20, where the hot-melt adhesive yarn melts
and then hardens, it is possible that the embossed layer 20 may
extend slightly beyond the preset area and blend with the area of
the plain cloth 10 not intended to be embossed. Indeed, the
description that the embossed layer 20 covers the plain cloth 10 is
not intended to limit the scope of the present disclosure.
[0029] The predetermined stamp may include a predetermined design
pattern (such as a logo or other mark) to be formed on the vamp, or
may include a structural reinforcement, which is a pattern that
acts to reinforce the structure of the vamp and may be applied in
areas where extra structural reinforcement is desirable, such as at
the toe, edges of eyelets, or shoe heel. Shoes provided with such
reinforcement of the vamp 1 may have better structural support or a
greater resistance to wear and tear. To summarize, the embossed
layer 20 is formed on the vamp 1, to form the predetermined design
pattern, the structural reinforcement, or a combination
thereof.
[0030] The plain cloth 10 may be dried in 100.about.200.degree. C.
of hot air generated by a hot blow drying device, so that the plain
cloth 10 is at a temperature between 150.degree. C. and 190.degree.
C. Next, the plain cloth 10 is cold pressed with the cold press
apparatus according to predetermined parameters. For example, one
of these predetermined parameters is a temperature of the pressing
plate of the cold press apparatus, which is in the range 0.degree.
C. to 25.degree. C. That is, the plain cloth 10 is pressed with the
pressing plate at the set temperature to form the embossed layer
20.
[0031] When the knitting machine knits the hot-melt adhesive yarn
together with the at least one other different kind of yarn to form
the breathable plain cloth 10, the area to be embossed into the
embossed layer 20 (for the purpose of applying the predetermined
design pattern or structural reinforcement) is knitted with a
higher-density of the hot-melt adhesive yarn than the other area on
the plain cloth 10. This is done in order to facilitate the
formation of the embossed layer 20, and is done in a controlled
manner, for instance by setting a suitable composition
configuration on the knitting machine. In another embodiment, the
hot-melt adhesive yarn may be a fiber yarn that has dual melting
points. For example, the inner core and outer cladding layer of the
fiber yarn may differ in their melting points. The outer cladding
layer may have a lower melting point that facilitates the weaving
process and increases the color fastness of the yarn fiber if dyed.
The inner fiber core may have a higher melting point and a higher
stiffness and so provide for a more sturdy structure of the vamp 1.
The desired characteristics of the hot-melt adhesive yarn are
developed as follows. Yarn of the same material but with different
melting points for the inner and outer layers can be produced in
the process of drawing the yarn by controlling the degree of
crystallization of the fibers or by wrapping the drawn yarn with
the same yarn material. Due to the inner and outer layers of the
yarn originating from the same material, their physical properties
are similar and this simplifies the procedure for controlling the
parameters for the knitting process. Also, when the yarns are made
from the same material, recovery of leftover selvage is easier, and
so a greater proportion of the yarn can be recycled, thus reducing
the cost, energy use, and environmental impact of the manufacture
of the vamp.
[0032] In another embodiment, the colored layer 30 is disposed on
the plain cloth 10 or the embossed layer 20 by manner of digital
printing. The colored layer 30 is formed in an area enclosed by the
crop mark 11. That is, the digital printing is performed to only
stain the area of the vamp 1 that includes the embossed pattern.
The leftover cloth to be cut is not stained, thereby reducing costs
related to the time taken to stain and the amount of yarn material
to stain. Moreover, the unstained cut leftovers may be recovered,
recycled and reused, thus making further savings in the cost of the
yarn material used and so reducing the environmental impact of the
manufacture of the vamp. Different areas of the colored layer 30
may be stained with different colors. For example, in the plain
cloth 10, a blue or black colored layer 30 may be formed in the
area without the embossed layer 20, and a red or yellow colored
layer 30 may be formed on the embossed layer 20 that is serving as
the predetermined design pattern. Alternatively, a white or milky
colored layer 30 may be formed on the embossed layer 20 that is
serving as the structural reinforcement.
[0033] In practice, and in accordance with the aforementioned, the
process of manufacturing the vamp 1 of the present disclosure
includes the following steps. In a step S1, the knitting machine is
operated to knit the hot-melt adhesive yarn together with at least
one other different kind of yarn to form the breathable plain cloth
10. In a step S2, the cold press apparatus is operated to cold
press the plain cloth 10, and the hot-melt adhesive yarn of the
plain cloth 10 melts and hardens during the cold press, so as to
form the embossed layer 20 on the plain cloth 10. Next, where
staining of the plain cloth 10 is not required, in a step S3 the
plain cloth 10 having the embossed layer 20 is cropped along the
crop mark 11, so as to obtain the vamp 1 with the embossed pattern.
Alternatively, where the plain cloth 10 is to be stained, in a step
S4 after the step S2, the digital printing is performed to faun the
colored layer 30 on the embossed layer 20 or the plain cloth 10.
Next, in a step S5, the plain cloth 10 having the embossed layer 20
and the colored layer 30 is cropped along the crop mark 11, to
obtain the vamp 1 with the embossed pattern.
[0034] The above described process provides a basis for the
manufacture of the vamp of the present disclosure, and may be
elaborated or adjusted to improve the manufacturing efficiency and
quality of the vamp product. For instance, the vamp product may be
made to have improved breathability, structural support, resistance
to wear and tear, and other desirable features. Additionally, in
order to reduce costs and increase the profit margin, the time
taken for manufacture may be shortened and the amount of selvage
leftovers may be reduced. In this way, a high quality shoe product
can be manufactured that can be sold at a reasonable price.
[0035] The above description is for the purpose of illustration
only and shall not be interpreted in any way to limit the scope,
configuration or applicability of the present invention. A person
skilled in the art may carry out many changes and modifications in
the described embodiments without departing from the spirit and the
scope of the present invention, which is intended to be limited
only by the appended claims.
