摘要： PURPOSE: To improve the shape-retainability, dimensional stability and washing resistance of nonwoven fabric made of vegetable fiber by applying a polymer processing treatment before or after the softening treatment of the fabric and giving irregular strain to the fabric by a flexing machine or a tumbler. CONSTITUTION: A web is produced by using vegetable fibers longer than a prescribed length. Nonwoven fabric is produced by interlacing the fiber of the web by a high-speed fluid jet. Usually the nonwoven fabric is subjected to softening treatment or rubbing treatment after a polymer processing treatment when the thickness or weight of the fabric is smaller than prescribed levels or without using the polymer processing treatment when the thickness or weight is larger than prescribed levels. The fiber bundles are loosened to loosen the interlace, flexibilize the fiber, form a twist, give a natural unevenness and shading irregularity and form raised fibers and fluffs. Polymer processing treatment is applied to improve the shape-retainability, dimensional stability, washing resistance, etc., of fabric free from polymer processing treatment.

摘要： PURPOSE:To enhance productivity and the stability of quality by a method wherein a sheet like article is once passed through a rubbing processing machine and a gripping machine to be turned in its direction and a passing position is changed to again feed back the sheet like article to the same rubbing processing machine or gripping machine. CONSTITUTION:The center positions of gripping machines C1, C2 are shiftered and the intervals between the movable grippers 14b, 14c and 16b, 16c of position fixed gripping devices 14a, 16a are made narrow by operating an air cylinder 15 to hold a sheet like article. Driving force is transmitted by a connection shaft 11 and the crank shaft 13 present at an eccentric position in a connector 12 and the gripping machines C1, C2 are rubbed like hand rubbing in the same direction in such a state that the center positions thereof are shifted. In the same gripping machine, one of the grippers is used in the initial feed of the sheet like article and the other one holds a processed product. Since the sheet like article generates 'the shift in the lateral direction' or 'overlapping' with the elapse of time in a rubbing processing machine 3 or in the vicinity thereof, each gripping machine is reversely operated in order to correct this state.

摘要： PURPOSE:To apply stable crease having steric feeling to a base material composed of woven or knit cloth, etc., by applying an adhesive layer to the base material, laminating an inorganic film or organic film, etc., and subjecting the laminate to flexing or bending treatment under a condition corresponding to the glass transition temperature of the adhesive layer. CONSTITUTION:A polymeric adhesive (e.g., vinyl adhesive or acrylic adhesive) is scattered on a base material composed of a woven or knit cloth or a fiber sheet produced by raising the cloth to form a sporadic or continuous adhesive layer. An inorganic film (e.g., aluminum foil), an organic film (e.g., plastic film) or a sheet is laminated on the above adhesive layer with or without pressing and the laminate is, e.g., melted with heat to obtain a laminated composite sheet material. The sheet material is creased by creasing process with a creasing machine and cooled below the glass transition temperature of the adhesive to set the crease and form a permanent crease deeply intruding in the adhesive layer in contrast with conventional embossing process in which the crease is limited on the surface layer. The product is suitable as a material for clothes, bags, footwears, etc.
