Description

THE COLORING METHOD OF MUCTI COLOR PATERN ON SURFACE OF LEATHER}

The present invention is molded in a beautiful and exceptional way by irregular and three-dimensional color pattern on the leather skin surface to produce shoes, handbags, bags and clothing mainly using leather in a variety of colors on the surface of the leather to produce more value-added products It relates to a method of molding a pattern.

Leather fabrics for the manufacture of leather garments, bags, handbags, and shoes currently on the market are mainly of the kind smooth or slightly rough on the surface or dyed in a simple form without any pattern on the surface. In most cases, the product is not glossy and there is no volume sense of the pattern itself.

Therefore, although leather is known to have a simple pattern on the surface by engraving the leather fabric in recent years, the leather fabric of such a configuration has not been put to practical use due to the defect that causes deformation.

The present invention aims to increase the merchandise value of various leather products using the same by forming a more beautiful and different pattern on the leather surface by solving the above disadvantages.

The present invention provides a combination of white pigments, waxes, filler pigments, aqueous pigments, urethane binders, soft binders, gloss pigments, soft acrylic binders, solid acrylics, and the like to form a pattern of various colors on the leather surface. The color dye having a saturation of 2 to 5 degrees is sprayed for each unique item of leather (SN-9001 to SN-9005), so that the surface of the leather is molded into a pattern of various colors.

This is sprayed once or twice with chemicals mixed with white pigments, waxes and filling pigments, polished pigments, aqueous pigments, urethane binders, soft binders, soft acrylic binders, and solid binders on the surface of leather cut to a suitable size. A first step of drying and processing at a rate of 7 mm per minute while pressing at 30 kg / cm 2 with a heat of 90 ° C .; A second step of spraying and drying the mixed solvent of the racker and the rack machine once; It is dried by spraying 1 ~ 2 times with chemicals such as racker, rack machine, gold leaf, silver foil, etc., and then press the press pressure of 20㎏ / ㎠ / second at the temperature of 40 ℃ while checking the pattern by color check and handwork. A third step of dismantling and then dismantling; Selective mixing of black lacquer, black dye, brown dye, yellow dye, red dye and Bordo dye with racker and thinner is carried out by heat pressing at 30kg / ㎠ heat pressure for each unique item of commercialized leather. It is characterized in that the color pattern penetrates the leather surface by the fourth step of heating to 80 ℃ at a rate of and sprayed once or twice with a mixed drug of the racker and thinner.

Hereinafter, the present invention will be described in detail according to the process of the examples.

EXAMPLE

Phase 1 (Pigment Treatment Process)

White Pigment 180g

30 g of wax

Filler 30g

Luster 40g

Water 400g

Urethane Binder 130g

Soft binder 120g

Soft Acrylic binder 120g

The mixture (medicine) was sprayed once or twice on the surface of the tanned skin of a constant size, and then treated at a rate of 7 mm / min at a pressure of 30 kg / cm 2 while heating at a temperature of 90 ° C. After spraying once or twice with the above mixture, it was dried to obtain leather having a pigment adhered to the surface.

2nd process (road treatment process)

Lacguer 100g

Lacguer Thimmer 200g

The mixed paint is dried by spraying the leather surface obtained in the first step about once.

3rd process (color pattern check process)

Lacguer 100g

Lacguer Thimmer 200g

Gold peil and silver peil 10g

After spraying the above chemicals once or twice on the spray-dried leather surface in the second process, they are dried and pressurized at a press pressure of 20㎏ / ㎠ / second at a temperature of 40 ℃ while checking the pattern by color check and handiwork and then dismantled. Let's do it.

4th process (coloring process of selective color pattern)

In the above process, black lacquer (black lacquer), black dye (dye black), brown dye (dye brown), yellow dye (dye yellow), red dye (dye red), dye bordo dye (dye bordo) and the optional racker and thinner Each leather's unique items (SN-9001 to SN-9005) to be molded and mixed are pressed at a heat pressure of 30㎏ / ㎠ and heated to a heat of 80 ° C at a rate of 7mm per minute. 100g) and a thinner (200g) mixed with a spray once or twice and dried to allow the color pattern to penetrate the leather surface.

In the above process, the chemical content of the drug applied to the unique item of leather is as follows.

SN-9001 mixes black racker 100g, black dye 100g, brown dye 30g, thinner 500g, racker 200g, and SN-9002 uses brown dye 80g, black dye 100g, yellow dye 30g, thinner 500g, racker 200g do.

SN-9003 uses 120g of Borado dye, 70g of red dye, 20g of brown dye, and 500g of thinner and 200g of racker.

In the SN-9004, 60g of black dye, 80g of yellow dye, 30g of brown dye are mixed with 500g of thinner and 200g of racker. In SN-9005, 120g of brown dye and 70g of yellow dye are mixed with 500g of thinner and 200g of racker. The color leather can be molded into various forms, thereby improving color leather as a high value-added product.

As described above, the present invention sprays and pressurizes with various colors of dyes and pigments on the surface of the leather skin, thereby making the irregular pattern of the color to the surface of the leather to be molded molded high value It is effective to improve the value goods, and also the leather produced according to the present invention can maintain the primary color by not cracking or causing deformation of the colored layer on the surface, and in particular, it is not caused by deformation of the leather skin. It is effective to prolong the life of the product.
