FIELD OF THE INVENTION
[0002] The invention relates to a method for producing printed
textiles for motor vehicles, wherein the textiles consist of a
polyester-based top material and a bottom material and in the case
of which at least a thickener and a UV absorber are introduced into
the top material in a foulard process, the top material is dried,
the digital printing process is carried out on the dried top
material, and the printed top material is laminated with the bottom
material.
BACKGROUND OF THE INVENTION
[0003] EP 2 281 940 A1 describes a printing method on a washable
fabric, for example. EP 0 965 681 A1 describes the production of a
printed polyester textile, in the case of which the polyester
material is pretreated with certain products.
SUMMARY OF THE INVENTION
[0004] The invention is based on the object of improving a method
for producing printed textiles of the above-mentioned type, so that
the textiles and the dyes printed thereon, are especially abrasion
resistant.
[0005] According to the invention a method is provided for
producing printed textiles for motor vehicles. The textiles have a
polyester-based top material and a bottom material. At least a
thickener and a UV absorber are introduced into the top material in
a foulard process. The top material is dried and a digital printing
process is carried out on the dried top material. The printed top
material is laminated with the bottom material. The colorless ink
is applied to the top material in the printing process when
applying the ink
[0006] In a method for producing printed textiles for motor
vehicles, wherein the textiles consist of a polyester-based top
material and a bottom material and in which at least a thickener
and a UV absorber are introduced into the top material in a foulard
process, the top material is dried, the digital printing process is
carried out on the dried top material, and the printed top material
is laminated with the bottom material, provision is made according
to the invention for colorless ink to be added to the top material
in the printing process when adding the ink The colorless ink, also
identified as "blind-ink", is preferably applied simultaneously
with the colored ink by means of a separate print head. The
penetration of the colored ink is thus increased due to
"gravitation".
[0007] The colorless ink preferably has the same or at least a very
similar viscosity as the colored ink The colorless ink also has
pigments, but colorless pigments. The colorless ink is used in
particular in connection with bright dyes. Preferably, dark dyes
are applied without adding colorless ink In another preferred
embodiment, at least the same quantity of colorless ink as colored
ink is applied for some bright hues. Preferably, more than twice or
more than three-times as much colorless ink than colored ink is
applied. Across all dyes, the ratio of colorless ink as compared to
colored inks is preferably at least 20% and maximally 50%, in
particular between 30% and 40%.
[0008] Preferably, a hydrophilizing agent is introduced into the
top material in the foulard process. The top material, which
consists substantially of polyester or preferably completely of
polyester, respectively, to thus be designed to be hydrophilic,
thus hygroscopic. The absorption of the dyes or inks in the
subsequent printing process is improved through this. Preferably, a
dispersion of hydrophilic polymers comprising functional
polysiloxanes is used for this purpose. For example, a product,
which has this effect, is the product ULTRAPHIL by Huntsman.
[0009] In another preferred embodiment, a corona or plasma
treatment is carried out prior to carrying out the printing
process. The surface of the top material is thereby either
pretreated using the corona method, which is considered to be a
physical pretreatment by means of high voltage. In the plasma
treatment, it is preferably to use an atmospheric pressure plasma.
It is produced as a highly ionized gas and is used on the surface
of the top material. The surface is activated through this. As a
result, this leads to a better adhesion of the dyes, which are
applied later. The surface tension is reduced. As a result, an
improved wettability of the top material and a higher penetration
depth of the inks is achieved. The abrasion resistance of the
applied inks and/or dyes is increased as well. Preferably, the
corona or plasma treatment is carried out prior to carrying out the
foulard process.
[0010] In a further preferred further development of the invention,
the top material is subjected to an enzyme treatment prior to
carrying out the foulard process. Preferably, such an enzyme
treatment is carried out prior to carrying out the foulard process.
The use of the product TEXAZYM PES by INOTEX spol. s.r.o. from the
Czech Republic is possible here, for example.
[0011] The method and the further developments can be carried out
in combination with one another. In particular, the combination of
the corona or plasma treatment of the top material and the use of
the colorless ink in the printing process in combination with one
another is preferred. In addition, the combination of the enzyme
treatment with the colorless inks is possible as well. The
combination of the enzyme treatment and the corona or plasma
treatment is also an option for improving the printing result, in
particular with regard to the abrasion resistance.
[0012] Preferably, the used top material consists either completely
of polyester or of polyester with natural yarns or artificial
yarns.
[0013] The top material is thereby intended for automobile interior
design products. The textiles have a top material and a bottom
material, wherein the bottom material is typically provided with a
foam or foam material. Preferably, a deaerating agent is also
introduced into the top material in the foulard process. For
example, the deaerating agent can contain alcohol, it can in
particular be based on alcohol. Preferably, a wetting agent is
additionally also introduced. Preferably, it can also be a mixture
of aliphatic hydrocarbons and alcohols. For example, the product
LYOPRINT AIR by Huntsman Advanced Materials LLC, USA, is suitable
here. The thickening agent is preferably also introduced
simultaneously in the foulard process. This prevents the running of
the ink at a later point in time. This can be a polyacrylate, a
guar or an alginate, for example. A running of the ink is prevented
therein. For example, the UV absorber is a traizine, in particular
an O-hydroxyphenyl-triazine composition. As products, THERMACOL MP
by Huntsman is possible here for the thickener and UV-Fast P by
Huntsman is possible as UV absorber, for example.
[0014] In another preferred embodiment of the invention, the
printing process is carried out using dispersion dyes and a drying
takes place immediately thereafter. It is preferably thereby that
the drying is carried out in a clamping of the top material. The
drying is preferably carried out using hot air. In the context of
the application of the printing dyes, the above-described
introduction of the colorless ink (blind ink) can be carried out at
this location shortly before applying the printing inks.
[0015] In another preferred embodiment of the invention, a fixing
step, in response to which the ink is fixed, is carried out after
the printing process. This is also referred to as a steaming or
preferably as a steaming process, wherein a treatment with steam is
carried out at over 100 degrees Celsius, preferably 180 degrees
Celsius. The top material is thereby preferably clamped on a
clamping frame. In the alternative, a drying can also take place in
a hot flue. In the alternative, this step can also take place by
means of a calender equipment or a machine calender.
[0016] Preferably, the top material is also washed and dried in two
further steps after the printing process and the fixing step. In
the washing process, caustic soda or hydrosulphide and a dispersant
or a detergent comprising tensides is preferably used. The
thickening agent and unfixed dyes are washed out by means of the
used detergents. The abrasion resistance is further improved
through this. The top material is tried in the subsequent drying
step. Preferably, this takes place on a clamping frame.
[0017] The method will be explained in more detail below with
reference to the sole figure of the drawing.
[0018] The various features of novelty which characterize the
invention are pointed out with particularity in the claims annexed
to and forming a part of this disclosure. For a better
understanding of the invention, its operating advantages and
specific objects attained by its uses, reference is made to the
accompanying drawings and descriptive matter in which preferred
embodiments of the invention are illustrated.
BRIEF DESCRIPTION OF THE DRAWINGS
[0019] In the drawings:
[0020] FIG. 1 is a schematic view showing aspects of the method for
producing printed textiles for motor vehicles
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] In step 1, the top material 2 is clamped onto rollers 3 and
is washed and/or rinsed in a container 4. A drying on a clamping
frame 5 takes place in the same clamping on the rollers 3. A corona
or plasma treatment takes place in step 8, which is only
illustrated as block 9 herein, in which the surface of the top
material 2 is treated by means of ionized gas or by applying high
voltage, whereby the wettability is increased. The foulard process
takes place in the next step 10, which is also identified as
slogging or squeezing. The top material 2 is thereby squeezed
between rollers 12 in a container 11. The container 11 contains a
liquid 14 comprising additives, which are applied to the top
material 2 through this. Provision is made in the liquid 14 in
particular for a thickening agent, a UV absorber and a deaerating
agent. The thickening agent prevents the running of the ink This
can be polyacrylate or guar, for example. This is also referred to
as a steaming or preferably as a steaming process. The UV absorber
improves the long-life cycle of the top material 2 in response to
the UV irradiation. For example, a product, which is based on an
0-hydroxyphenyl-triazine composition, can be used here. In
addition, a hydrophilizing agent is also contained in the liquid
14, which is introduced into the top material 2 in step 10. The top
material 2, which consists of polyester, thus becomes hydrophilic
and better absorbs the dyes, which are applied at a later point in
time, in particular the ink
[0022] In step 8, a pretreatment of the top material 2 with enzymes
can also take place as an alternative or as additional independent
step. In response to the treatment with enzymes, this preferably
takes place in an independent process, for example in a dying
machine or also by means of a foulard treatment. The actual
printing process takes place in subsequent step 20. The top
material 2 is clamped onto rollers 23 and is thereby printed
digitally in step 21. A "blind ink", a colorless ink, can be
applied thereby, so as to improve the wetting. The actual printing
also takes place simultaneously in step 21. A drying with hot air
takes place in the block 22. This takes place immediately
subsequently in the same clamping of the top material 2. A fixing
step takes place in step 30. The top material 2 is clamped onto
rollers 33 and is guided through a steamer. The top material 2 is
treated with steam at 180 degrees Celsius here, so that the ink is
fixed thereby. The steaming equipment is identified with 34 here. A
clamping onto rollers 44 takes place again in a further step 40,
wherein the top material 2 is guided through a container 41, which
contains caustic soda or hydrosulphide or sugar and a dispersant or
a detergent comprising tensides. The thickening agent is rinsed out
here and unfixed dyes are rinsed out. The abrasion resistance is
further improved through this. In the same clamping of the top
material 2, a drying on clamping frames also takes place in a step
42. A laminating of the top material 2 with the bottom material and
the foam or foam material to the printed textile takes place in a
subsequent step 50. This textile is then cut to size and is sized
correctly to fit the individual uses. For example, seat covers for
motor vehicles for motor vehicles can then be made from or interior
lining the textile.
[0023] While specific embodiments of the invention have been shown
and described in detail to illustrate the application of the
principles of the invention, it will be understood that the
invention may be embodied otherwise without departing from such
principles.
