Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural fiber in which a thermoplastic synthetic resin emulsion is preliminarily impregnated into a predetermined area of a cloth mainly made of natural fiber such as cotton, wool and silk to form an uneven pattern in the area. The present invention relates to a method of embossing a fabric whose main material is.

[0002]

2. Description of the Related Art A method of forming embossing on a fabric mainly made of natural fibers such as cotton, wool and silk which are not suitable for embossing is a fabric mainly made of natural fibers such as cotton, wool and silk. The hot-melt film or the foamed resin was sandwiched between the (base material) and the backing cloth on the back surface of the base material, and unevenness was processed by hot pressing.

[0003]

In the conventional method as described above, the base material itself is not molded, but is formed by concavo-convex molding of the sandwiched hot melt film or foamed resin. In this case, the irregularity processing is likely to lose its shape, and by washing, it becomes a cloth (base material).
There was no reliability of the processed product due to the fact that the hot melt film or the foamed resin and the backing cloth were easily peeled off and the iron resistance was poor. Furthermore, since the hot-melt film or the foamed resin is attached to the cloth (base material) such as natural fibers such as cotton, wool, silk, etc., when this is worn, the cloth feels stiff and the cloth feels worn. The texture of (base material) could not be utilized.

[0004]

In order to achieve the above object, the present invention provides a cotton cloth for solving the above problems.
A synthetic resin emulsion is impregnated into a predetermined area of a fabric mainly composed of natural fibers such as wool and silk, and after drying, a predetermined pattern, pattern, or symbol is hot-pressed with a heat die to apply the heat to the area. This is a method for easily performing direct embossing of a fabric (base material) whose main material is natural fibers such as cotton, wool, and silk by performing embossing.

Furthermore, a thermoplastic synthetic resin emulsion is impregnated into a predetermined area of a cloth (base material) whose main material is natural fiber such as cotton, and the thermoplastic synthetic resin emulsion is impregnated into a predetermined pattern, pattern, The symbol is colored and printed, and after it is dried, a predetermined pattern is printed on the colored printed part with a heat die.
It is also possible to apply embossing with painting by hot pressing the handle and symbol.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 An embodiment will be described with reference to the drawings.
In FIGS. 1 to 5, a synthetic synthetic resin emulsion is impregnated into a region a to be embossed of a fabric (hereinafter, referred to as a base material) 1 which is mainly made of natural fibers such as cotton, wool, and silk, and is subjected to thermoplastic synthesis. The resin emulsion impregnated portion 2 is formed. Was used). Acrylic ester-based polymer emulsion 60 parts Acrylonitrile-butadiene-based emulsion 40 parts To 100 parts of the above synthetic emulsion (as stabilizer and penetrant) sodium dialkylsulfosuccinate 1 part Water 10-40 parts Made by mixing After the thermoplastic synthetic resin emulsion is sprayed or brush-applied, the structure of the predetermined region a of the base material 1 to be embossed is sufficiently permeated with the thermoplastic synthetic resin emulsion to form the thermoplastic synthetic resin emulsion impregnated portion 2. This is air dried.

The dry base material 1 to be processed is placed on the elastic silicon sponge rubber plate 8 having a predetermined thickness on the upper surface of the fixed base 7, and 180 is provided in the embossed area of the base material 1.
400 with a hot mold heated to about 0 ° C to 220 ° C
Pressing time of about 30 at pressing pressure of kg-2000 kg
When the die 3 is pressed for about 90 seconds, the base material 1 and the elastic silicon sponge rubber plate 8 are pressed by the die pressing pressure in correspondence with the irregularities provided on the die 3 pressing surface. It deforms as shown in FIG.

When the pressed state of the mold 3 is released, the elastic silicon sponge rubber plate 8 immediately returns to the original smooth plate, but the predetermined area 2 of the base material 1 is formed from the concave portion 3 and the convex portion 4. The uneven pattern 6 that appears appears and remains. In addition, it goes without saying that the conditions for the above-mentioned press working differ depending on the type of the substrate 1, the thickness of the substrate 1, or the size of the mold. Even in this case, accurate alignment is required in order to accurately determine the predetermined region a to be embossed.

The embossed product thus produced was subjected to the following tests, and the degree of disappearance of embossing was tested. The results are as follows. 1. Storage test in a constant temperature bath (a) Temperature 50 ° C (± 3 ° C), humidity 70% (± 5
%) And left for 3 days in a constant temperature bath, the degree of disappearance of embossing was examined. As a result, almost no embossing disappeared. (B) Temperature 50 ° C (± 3 ° C), humidity 70% (± 5
%), The embossing disappearance was examined, and the embossing disappearance was scarcely observed.

[0010] 2. Washing resistance (JIS L 0217
Method 103 Tumble dry) (a) After repeating the treatment 5 times, the degree of disappearance of embossing was examined. As a result, almost no disappearance of embossing was observed. (B) After the treatment was repeated 10 times, the degree of disappearance of the emboss was examined. As a result, almost no disappearance of the emboss was observed. 3. Dry-cleaning resistance (commercial dry-cleaning 5 times repeated) (a) After the cleaning was repeated 5 times with a cleaning liquid containing perchlorethylene as a solvent, the degree of disappearance of the emboss was examined, and it was found that the emboss disappeared I couldn't see it. (B) After the cleaning treatment was repeated 5 times with a petroleum-based cleaning liquid as a solvent, the degree of disappearance of the emboss was examined. As a result, almost no disappearance of the emboss was observed.

4. Iron resistance (dry iron pad cloth, press for 30 seconds, 5 reciprocations) (a) Dry iron pad cloth at ironing temperature of 100 ° C, press for 30 seconds, reciprocate 5 times, then disappear embossing As a result of examining the degree, the disappearance of the emboss was hardly seen. (B) After ironing a dry ironing cloth at an ironing temperature of 200 ° C., pressing for 30 seconds and reciprocating 5 times, the degree of disappearance of the emboss was examined. As a result, almost no disappearance of the emboss was observed.

5. Formalin test The presence or absence of formalin was tested for the embossed product obtained above by the test method stipulated in the Ministry of Health and Welfare Ordinance No. 34 of the Ministry of Health and Welfare 1974, "Enforcement Regulations concerning the Regulation of Household Products Containing Hazardous Substances", and the following results were obtained. Got Absorbance A-A ₀ = 0.05 or less

6. Lightfastness test JIS L-0842 (carbon arc lamp 20 hours) was performed, and the following results were obtained. Level 3-4

[0014]

Example 2 In FIGS. 6 to 7, even when the cloth (base material) 11 whose main material is natural fiber such as cotton, wool, silk, etc. is colored, the base material is the same as in the above embodiment. 11. A predetermined region b to be embossed 11 is impregnated with a thermoplastic resin emulsion and dried to form a thermoplastic resin emulsion impregnated portion 12, and a predetermined pattern is formed in the thermoplastic synthetic resin emulsion impregnated portion 12. A colored print 13 is applied in advance to patterns and symbols. After the colored print 13 is dried, a predetermined pattern, pattern, or symbol is pressed on the colored printed portion with a heat die 17 by a heat die to form a concave portion 14 and a convex portion 15 corresponding to the uneven surface of the die 17. The uneven pattern 16 having a predetermined pattern can be made to appear.

It is to be noted that the base material 11 to be embossed uses an elastic silicon sponge rubber plate 8 having a predetermined thickness on the upper part of the fixing base 7 as in the above-mentioned embodiment, as in the above-mentioned embodiment.
