Abstract

PURPOSE:To apply a wash-resistant embossed pattern to a cloth without deteriorating the softness of the cloth. CONSTITUTION:After applying a protruded pattern 18 to a cloth 10, a lining cloth 14 is bonded to the ground part around the protruded pattern 18 to fix the pattern. Since the ground part around the protruded pattern part 18 of the cloth 10 is fixed with the lining cloth 14 at the back, the spreading of the protruded pattern 18 is prevented to resist the disappearance of the pattern 18 by washing (water washing, dry cleaning, etc.).

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a method for imparting an embossed pattern (particularly a convex pattern) to a cloth.

[0002]

2. Description of the Related Art Various methods are used to give an embossed pattern to a cloth. In any method, even if a deep pattern with a clear contour is formed immediately after the application, it will be natural after a while. The contour becomes unclear and the pattern becomes shallower. Especially in the case of fabrics made of natural materials, the embossed pattern disappears significantly.
A method of fixing the embossed pattern by adhering the sponge-containing cloth and imparting an embossed pattern together with the cloth is used.

[0003]

The sponge fixed to the back of the cloth cannot sufficiently exert the effect of fixing the embossed pattern unless the sponge has a certain thickness. In such a case, the softness of the clothing material) is greatly impaired, and the skin feels bad. Therefore, conventionally, the garment provided with such an embossed pattern could be worn only after wearing a thick undergarment. The present invention solves such a problem and does not disappear even if washed,
Moreover, it is to provide a method for providing an embossed pattern that does not impair the flexibility of the fabric.

[0004]

An embossing pattern-applying method for a cloth according to the present invention, which is made to solve the above-mentioned problems, is a method in which a convex pattern is applied to a cloth and then a ground portion around the convex pattern is formed. The convex pattern is fixed by adhering a lining.

[0005]

The embossed pattern (convex pattern) produced by the method according to the present invention is fixed on the back surface with the surrounding ground portion, so that the convex pattern portion is prevented from spreading and the convex pattern is retained as it is. To be done. Since the lining only acts to prevent the spread of convex patterns, it is possible to use extremely thin ones. In addition to ordinary thin fabric, a net-like sheet in which extra fine yarn is knitted in an extremely coarse texture. Alternatively, a plastic sheet such as a vinyl sheet (preferably a breathable sheet) can be used.

EXAMPLE An example of an embossing pattern (convex pattern) providing method according to the present invention will be described with reference to FIG. First, prepare male and female molds 11 and 12 that have been subjected to a mold processing of a desired pattern, and
Place 1 down and male 12 up. In this embodiment, both types 1
In both 1 and 12, mold surfaces 11a and 12a are made of silicon rubber which is easy to mold. Behind the die surfaces 11a, 12a of the female die 11 and the male die 12, heaters 11c, 12c are provided with metal plates 11b, 12b for equalizing and equalizing the die surfaces 11a, 12a interposed. The mold surfaces 11a, 12
It is preferable to mix metal powder such as aluminum powder into the silicon rubber before molding a so that the mold surfaces 11a and 12a have good thermal conductivity.

After setting the upper and lower molds 11 and 12 in a press and heating the mold surfaces 11a and 12a to appropriate temperatures by the heaters 11c and 12c, the cloth 10 to which an embossed pattern is to be applied is placed in the lower mold (female mold). ) 11 (Fig. 1
(A)). When the fabric 10 that is the object to be processed is a natural fiber such as cotton, it is desirable to subject the fabric 10 to resin treatment in advance in order to more securely fix the embossed pattern. For example, after the cloth 10 is impregnated with acrylic resin, glyoxal or the like, it is dried before embossing.
In the case of synthetic fibers such as polyester and nylon, a relatively long-lasting embossed pattern can be provided without resin processing, but the resin processing makes the embossed pattern stronger.

Next, the upper mold (male) 12 is pushed down to press the cloth 1.
Heat and press 0 (b). Mold surfaces 11a, 1 during processing
The temperature and pressing time of 2a are, for example, 140-
160 ° C x 3 to 5 minutes, 170 to 2 for polyester
00 ° C x 3 minutes, 120 to 140 ° C x 3 for nylon
Set it as about a minute. The clearance between the male and female dies 11 and 12 may be set to 0 when the die surfaces 11a and 12a are made of silicone rubber and the cloth 10 is not so thick. However, if the fabric 10 is thick or knitted,
Alternatively, as described later, when the surfaces of the mold surfaces 11a and 12a are coated with a metal layer (or a metal plate), it is desirable to provide a thickness of the cloth 10 or a clearance slightly smaller than the thickness.

After applying pressure and heating for a predetermined time to give an embossed pattern to the fabric 10, the upper mold 12 is pulled up. Then, with the cloth 10 being placed along the mold surface 11a of the lower mold 11, behind the convex portion 18 (the cloth 1
Place the lining 14 on the back side of 0) (c). The size of the lining 14 is set to be slightly larger than the convex portion 18, and an adhesive (hot melt resin or the like) is applied to the surface of the lining 14 on the side of the fabric 10. A cloth or sheet with an adhesive may be used, or the cloth 10 may be coated with the adhesive. Since the lining 14 only serves to prevent the convex pattern 18 from spreading as described later, an extremely thin one can be used. As the adhesive, a heat-adhesive adhesive having an adhesive action at the above mold temperature is preferable, but a pressure-sensitive adhesive or the like may be used. When the convex portion 18 is relatively wide, the central portion of the lining 14 hangs down in the convex pattern 18 in the step (c), and it becomes difficult to perform the function of fixing the convex pattern 18. 14 is the pressing flat plate 16 side or the fabric 10 side in advance (convex pattern 1
It is desirable to temporarily fix it around (8).

Finally, the silicon rubber flat plate 16a is formed on the pressing surface.
(And iron plate etc. to make the pressing force uniform 1
6b is provided on the back of the lining 14 by a pressing plate 16
Is pressed against the fabric 10 to apply pressure and heat (d), and the lining 14 is adhered to the fabric 10 around the convex portion 18. When the pressing plate 16 is pulled up and the cloth 10 is taken out from the lower mold 11, the convex portion 18 of the cloth 10 is fixed by the lining 14 around the area 18 (e). Therefore, the convex portion 18 is prevented from spreading by the lining 14, and the convex portion (embossed pattern) 18 does not disappear even when washed.

In the above embodiment, for convenience of understanding,
A flat plate 16 was used as the upper mold for adhering the lining 14, but normally, as shown in FIG. 2, the upper mold (male) 12 used for giving an embossed pattern is directly pressed for adhesion. It is used for the purpose of inserting a pressing force distribution means (a steel plate may be sandwiched inside the silicon rubber plate 17) such as a thick silicon rubber plate 17 between the male mold 12 and the cloth 10. The method is realistic.

In the above embodiment, the mold surface 11 made of silicon rubber is used.
a and 12a were brought into direct contact with the fabric 10, but copper was
Mold surface 11a coated with a thin metal layer (plate) such as aluminum 1
2a may be used. Such a mold can be prepared by pouring silicon rubber into a metal plate formed into a predetermined embossed pattern. Note that gypsum or the like can be used instead of silicon rubber, and as the metal powder mixed therein, various materials such as copper and iron powder can be used in addition to aluminum.

[0013]

The embossed pattern (convex pattern) produced by the method according to the present invention prevents the expansion of the convex part because the ground portion around the embossed pattern (convex pattern) is fixed on the back side by the lining, and washing (water washing, dry cleaning, etc. Even if you do), the pattern does not disappear. Further, since the lining is merely fixed so that the ground portion (planar portion) around the convex pattern does not spread, a very thin sheet (rough cloth or the like) is sufficient. Therefore, the back side of the clothes is not made bulky, the flexibility of the clothes is not impaired, and the touch is not impaired, so that it is possible to give a permanent embossed pattern to shirts etc. become.
