- The purpose of the present invention is to provide synthetic resin fibers and synthetic resin sheet materials obtained by kneading non-fiber powder as raw materials.

[Means to solve the problem]

The synthetic resin fibers and synthetic resin sheet materials kneaded with non-fibrous powder according to the present invention are made by mixing ultrafine powdered animal and plant non-fibrous materials with synthetic fibers, semi-synthetic fibers, linear polymers of regenerated fibers, or two types of these materials. The gist of the present invention is to knead the chemical fiber material with a polymer made of a mixture of the above linear polymers.

Here, the animal and plant non-fibrous materials include plant materials such as bark, leaves, rice husks, wheat straw, rice straw, buckwheat husks, seaweed, and nuts, as well as leather, bones, horns, teeth, scales, shells, pearls, and coral.

Refers to animal materials such as the shells of hard-shelled animals, which are not customarily used alone as fibers. Further, the ultrafine powdered animal and plant non-fibrous material refers to a powder of animal and plant fibers in which the particle size of the animal and plant non-fibrous material is smaller than on the order of several hundred microns.

The gist is that the synthetic resin fiber and synthetic resin sheet 1 to material kneaded with the non-fiber powder of the present invention are spun into composite synthetic resin fibers and spread to form a composite synthetic resin sheet.

The synthetic resin fibers kneaded with the non-fiber powder of the present invention can also be made into fibers with a core-sheath structure by spinning the kneaded composition into a sheath that covers the surface of other fibers.

Furthermore, the synthetic resin fiber kneaded with the non-fiber powder of the present invention can be obtained by spinning a chemical fiber material consisting of a linear polymer of synthetic fiber, semi-synthetic fiber, or regenerated fiber, or a mixture of two or more of these linear polymers. This can be achieved by attaching ultra-fine powdered non-fibrous animal and plant material powder to the surface of the raw material yarn to cover the dazzling surface.

Furthermore, the synthetic resin sheet kneaded with the non-fibrous powder of the present invention is
Ultra-fine powdered animal and plant non-fibrous material powder is applied to the surface of a material film made by spreading a chemical fiber material made of a linear polymer of synthetic fibers, semi-synthetic fibers, or recycled fibers, or a mixture of two or more of these linear polymers. This can be achieved by adhering and coating the surface of the film.

As the fiber material, the following can be effectively used.

Animal and plant non-textile materials plant material Bark, leaves, nuts, rice husk, wheat straw, rice straw.

Buckwheat husks, seaweed, etc.

animal material Leather, bones, horns, teeth, fish scales, shells, pearls.

Semi-synthetic resin material Acetate, diacetate-1, triacetate, etc.

recycled fiber material 7- Rayon et al.

[Effect]

Various natural materials such as leather are themselves hygroscopic.

It is well known that this sheet material has excellent moisture permeability and texture.

The structure of the fiber of the present invention is that the ultrafine powdered animal and plant non-fiber material is kneaded with a chemical fiber material and spun or spread, or the ultrafine powder is applied to the surface of the spun or spread chemical fiber or sheet material. Due to the structure covered with this animal and plant non-fibrous material, countless through holes are formed on the surface of the fiber or sheet, and some of them become exposed on the surface of the fiber or sheet, causing the synthetic fiber to Excellent moisture absorption and moisture permeability properties.

It has a texture and feel to the touch.
