Therefore, it is strong, and due to the properties of the leather structure 1, it has breathability, moisture absorption, etc. close to that of leather. Also, F
The lim-shaped leather tissue 1 is sanded to the surface 3a.
It is exposed in a fluffy manner and has a similar appearance and feel to the lining.

用される。(Example) Figure 1 shows an example of the synthetic leather according to the present invention.
2 is a fine fibrous leather tissue obtained by finely crushing leather; 2 is a soft synthetic resin containing the leather tissue 1, and is used as the sheet 3; 0 synthetic resin 2; For example, vinyl chloride, nylon, ABS resin, etc. are used.

状皮革組織1を毛羽として露出させ裏皮状の表面3aと
なっている。この場合効果的に毛羽立たせるため、粗目
のサンディングディスクによりサンディングすることも
ある。The sheet 3 is made by extrusion molding a synthetic resin 2 containing fine fibrous leather tissue 1, slicing it to a predetermined thickness, and sanding the surface 3a of the sheet 3 to expose the fibrous leather tissue 1 as fluff on the surface 3a. The surface 3a has a lining-like surface. In this case, in order to effectively fluff it, it may be sanded with a coarse sanding disc.
又、サンディングは合成皮革の使用目的によって片面の
みとし他方の面は染料、塗料、油脂等の仕上剤により皮
革の銀面状とし、或は艶面に仕上げる場合もあり、両面
共毛羽立たせた裏皮状とする場合もある。Also, depending on the purpose of use of the synthetic leather, sanding may be done only on one side, and the other side may be finished with a finishing agent such as dye, paint, oil, etc. to give it a silvery surface or a glossy surface. Sometimes it is skin-like.

接着することにより、一体に積層させた実施例であり、
布生地4により更に引張強度、引裂強度等を増大させた
ものである。Furthermore, in the case shown in FIG. 2, a cloth material 4 such as stockinette is fused to one side of the sheet 3 during roll forming of the sheet 3, or heat and pressure fused to the sheet 3 which has been extruded and sliced. This is an example in which they are laminated together by bonding with a water-based vinyl urethane adhesive or the like.
The fabric 4 has further increased tensile strength, tear strength, etc.

通気性、吸湿性を損わないようにしたものである。FIG. 3 shows a synthetic resin 2 further containing a cellulose-based fine aggregate 5 such as wood flour or pulp powder, and the surface 3a is sanded to have a fluffy surface with a fibrous leather tissue l exposed. This is an example in which the grain 6 is formed by heat-compression bonding a grain roll or the like on this surface, and by incorporating the cellulose-based fine powder aggregate 5, the shape material properties of the grain 6 are improved, and the air permeability and moisture absorption of the aggregate 5 are improved. This is done so that the breathability and hygroscopicity of the synthetic leather are not impaired due to its properties.

同様の感触を有する。(Effect) The synthetic leather according to the present invention is finely crushed as described above, and a sheet is formed from the soft synthetic resin containing the fine fibrous leather tissue, and the surface of the sheet is sanded, and the Because the leather tissue is exposed in the form of fluff, the surface becomes suede-like.Furthermore, since the fluff is crushed leather tissue, it is also hygroscopic, and with the right amount of moisture, the surface becomes moist and slimy. It has almost the same feel.
又、合成樹脂によって繊維状皮革組織が連結され、から
みあった状態で固められているので、引張り強力、引裂
強力等にすぐれており。In addition, since the fibrous leather structure is connected by the synthetic resin and solidified in an intertwined state, it has excellent tensile strength and tear strength.
且つ該皮革組織によって皮革と近似した通気性、吸湿性
も具備されている。In addition, the leather structure provides breathability and moisture absorption properties similar to those of leather.
