。(Means for Solving the Problems) In order to make the leather-like fabric mentioned above even closer to original leather, the present invention provides a leather made of 50 to 250 mesh dry leather powder 2 and thermal Ijr plastic resin 1. The sheet 4 or the film is rubbed with a rolling roll to form a leather-like shape.

されることによりシート４が着色される。The leather-like fabric A is made of 50 to 250 mesh leather powder 2 which is dried and powdered until the remaining fiber content is within 3%.
0%, thermoplastic resin compound with thermoplastic resin 1 and plasticizer, stabilizer, etc. is 30-70%
It consists of a leather-like sheet 4 which is heated and formed by mixing % ffi hL ratio, and the leather acid powder 2 can also be made from crushed stratification or processing waste such as leather sanding powder ( In particular, tannin and chromium-treated leather powder has a rot-preventing effect) If the mesh is too small or too large, it will not be scattered into the resin compound when mixed with the resin compound and will become lump-like. This is important, and the sheet 4 is colored by mixing the leather powder 2 after being bleached or dyed in the foreground, or by adding a pigment during molding.

合等がある。Furthermore, in the case where the thermoplastic resin compound is mixed with short fibers such as nylon, polyester, polypropylene, etc. in addition to the leather powder 2 and is entangled with the leather powder 2 for reinforcement, and a lubricant, lf
Industrial gelatin is mixed in 3 to 30% of the thermoplastic resin compound as an F1 agent, and a foaming agent is mixed in to improve the lubricity with induced proteins and may increase ily adhesion, lipophilization, and water retention. In some cases, the material is foamed to give it elasticity and flexibility.

まれ、表面には皮革粉２のみが浮出る状態となる。The sheet 4 has a smooth surface and is made of thermoplastic resin between the leather powder 2.
After removing the skin layer made of thermoplastic resin by sanding the surface 4a as shown in Fig. 2, the rolls in the kneading device as shown in Fig. 3 are used. By passing through the fifth group, compression and restoration are repeated, and the resin 1 is pushed inside the sheet 4, leaving only the leather powder 2 floating on the surface.

。Next, as the sheet 4 passes through the 6 groups of kneading rolls, resin cracks 3' are created scattered in the resin 1 part of the sheet 4, so that the rebound resilience is lost and softness, suppleness, and a shiratori feeling are produced. As the rolls 5 and 6, cold rolls or heated rolls are used, and there are cases where only the rolls are used, and cases where a heating device, particularly preheating, and the rolls are used together.

In order to increase the strength etc., reinforcing fabrics such as paper, cloth, or non-woven fabrics made of various natural fibers are sometimes welded to the back surface of the sheet or bonded after the sheet is formed.

When pressed, the edge of the resin 1 part of the sheet 4'g- is cut off, creating a crack 3', and as a result, the resin part of the sheet 4'4 loses its rebound resilience and becomes soft and pliable, giving it a shiratori feel and an elk-like appearance. Also, large wrinkle-like grains 3 are formed around the 3° cracks on the surface, and because these cracks are formed, the moisture permeability 1 air permeability of the sheet 4, etc., which is originally formed to have leather-like properties. is further increased. Note that the concave portion created by the rolling process becomes a small grain shape centered on this concave portion, making it more similar to leather.

より衣料にも好適なものである。In addition, as the leather powder is extruded onto the surface as described above, and there are large and small grains, oils and fats for leather vinegar, paints, cleaning agents, etc. are absorbed well, and the leather remains in beautiful and good condition. It is suitable for various interior and exterior uses of buildings, furniture, etc., bags, shoes, bags, etc., in which leather has conventionally been used, and also for clothing due to its suppleness and drapability.
