Description

The present invention relates to a leather-like long sheet, parts and products thereof in the field of synthetic leather or artificial leather.

Conventionally, synthetic leather or artificial leather formed like a leather is made in place of the genuine leather, and products such as bags, shoes, belts, clothes and gloves are manufactured.

These leather-like products made of synthetic leather were unpopular with customers due to the surface color being monotonous, unsatisfactory in texture, and the shiny luster unique to chemical products.

Therefore, as a result of conducting a patent search on leather-like sheets and products, the applicant has found that Japanese Patent Publication No. 57-8232 discloses a method for producing a leather-like sheet, and Japanese Patent Application Laid-open No. Hei 5 (1993) discloses a method for producing a leather-like sheet product dyed lightly. 5-30280 publication etc. were searched. These disclose that the surface of the leather-like sheet can be subtly changed in color tone, and the monotonous surface tone can be eliminated and the leather-like sheet product can be improved to have a good texture. However, there was still a glaring luster unique to chemical products, which was highly unpopular with customers.

The leather-like long sheet, parts, and product thereof of the present invention are obtained by embossing the embossed surface of the required animal pattern on one side of the leather-like sheet base material of synthetic leather.
The surface of the base sheet is buffed to the surface of the base sheet by forming a short pile of ultra-fine fibers and easily dyeable nylon yarn or rayon thread on the surface of the base sheet. And embossing by removing the embossed pile on the surface of the base sheet
It is characterized in that a leather-like long sheet material is formed leaving a pile in the recesses of the nodule .

The leather-like sheet base material 1 of synthetic leather can be used for leather-like sheet materials such as polyurethane wet synthetic leather and polyvinyl chloride leather as conventionally known, and fiber sheets such as knitted fabrics and non-woven fabrics of nylon and rayon ultrafine fibers. A leather-like sheet material containing a polyurethane elastomer or a polymer mainly composed of polyurethane elastomer can be used.

On one side of this leather-like sheet base material 1, as shown in FIG. 1, embossing of the uneven surface of the required animal pattern such as goat, snake, crocodile, leopard pattern, etc. is performed, and the required crease 2 is attached, A short base easily dyeable nylon yarn or rayon yarn of ultrafine fibers is ionically bonded by electrostatic processing to form a base sheet 4 in which a required pile 3 is implanted.

Then, as shown in FIG. 2, the surface of the base material sheet 4 on which the pile 3 is planted is subjected to buffing, and the surface of the base material sheet 4 is embossed, leaving the pile 3 of the concave portion 5 of the crease 2 and the convex portion. The pile 3 of 6 can be removed to make a leather-like long sheet material 7.

Since the leather-like long sheet material 7 of the above material has not yet been given the required coloring,
Can be mass-produced and stored in advance. Then, as shown in FIG. 3, a desired dyeing of the customer is performed by a dyeing process in which the leather-like long sheet material 7 is sequentially immersed in a required dyeing tank 8 using a reactive dye or the like, as shown in FIG. It is possible to obtain a high-quality leather-like long sheet 9 that has a glossy luster peculiar to chemical products and eliminates a lot of unpopularity with customers, and provides a moist surface with suede tone and an elegant color tone. it can.

Then, the leather-like long sheet 9 is cut into the required bag, shoes, belt, clothes, gloves and other products and semi-finished parts, and the required leather is made from the dyed leather-like parts as in the past. Products such as bags, shoes, belts, clothes, gloves, etc. can be formed.

In the above, as shown in FIG. 3, a long leather-like long sheet material 7 is immersed in a dyeing tank 8 and dyed and cut into a required shape to produce semi-finished products and products. A long-skinned leather-like long sheet material 7 is cut in advance into the required shape of bags, shoes, belts, clothes, gloves and other semi-finished products, and these are mounted in a dyeing basket and used as a required dye. It is also possible to form the required leather-like bags, shoes, belts, clothes, gloves, etc. from the dyed leather-like parts.

1 to 4 show an embodiment of the present invention. As shown in FIG. 1, the polyurethane wet synthetic leather-like sheet base material 1 was embossed with a rugged pattern and provided with the required grain 2.

Then, as shown in FIG. 1, a short 0.8 denier rayon yarn with easy dyeability of ultrafine fibers is ionically bonded over the entire surface by electrostatic machining, and a required pile 3 of rayon flock is obtained.
The base sheet 4 is formed by implanting the surface of the base sheet 4 on which the pile 3 described above is buffed as shown in FIG. 2, and the surface of the base sheet 4 is embossed. The pile 3 of the convex portion 6 was removed while leaving the pile 3 of the concave portion 5 to obtain a leather-like long sheet material 7.

Then, as shown in FIG. 3, it was immersed in a dyeing tank 8 having a light brown reactive and disperse dye composition for a predetermined time, washed with water, and dried. As a result, as shown in Fig. 4, there is a shiny luster peculiar to chemical products, which eliminates a lot of unpopularity with consumers, and a high-quality leather that gives a moist surface with a suede tone and an elegant color tone. A long sheet 9 could be obtained.

In addition, the leather-like long sheet 9 is cut into the required shoe product parts shape, and the desired dyed product is sewn to create a suede moist surface and an elegant color tone. Could be manufactured.

The above leather-like long sheet is cut into the required bag, shoes, belt, clothes, gloves and other products and semi-finished parts, and the leather-like cut parts of this product and semi-finished parts are required. A leather-like bag, shoes with a high-class feeling that can obtain a moist surface of suede tone and elegant color tone by dipping in the dyeing tank and applying the required dyeing to the pile part of the concave part of the base sheet.
Products such as belts, clothes and gloves can be obtained.

FIG. 5 shows another embodiment of the present invention, in which the leather-like sheet base material 1 is embossed with a goat-patterned uneven surface, and the pile 3 is implanted as described above. The required animal pattern can be obtained. In this manner, a product dyed with a required color as a required animal pattern can be obtained.

Pile planting perspective view from the embossed state partially omitted of the embodiment of the present invention, The buffing explanation perspective view same as the above, Dyeing explanation diagram as above, A perspective view in which a part of the leather-like sheet formed by the above processing is omitted, The pile planting perspective view from an embossed state in which some of the other embodiments are omitted.
