摘要： A vinyl-alcohol-based polymer and vinyl-halide-based polymer are dissolved in a common organic solvent for them, a typical example of which is dimethylsulfoxide, to obtain a dope wherein a solution of the vinyl-halide-based polymer having a particle size of 1-50 .mu.m is present in the solution of the vinyl-alcohol-based polymer. This dope is spun into a low temperature solidifying bath comprising a solidifying solvent such as methanol, and the organic solvent. The resultant is subjected to extraction, drying, dry heat drawing, and optional heat shrinking or acetalization to obtain fiber. In the fiber thus obtained, the vinyl-alcohol-based polymer makes sea phases, and the vinyl-halide-based polymer makes island phases whose size is 0.1-3 .mu.m. The crystallinity degree of the vinyl-alcohol-based polymer is 65-85%.The polyvinyl-alcohol-based flame retardant fiber is useful for clothes, industrial materials, living materials and the like. It can be produced at low costs, and has excellent spinning stability and dimensional stability in hot water.

摘要： Provided is a high-performance PVA fiber and its production.Each filament of the PVA fiber of the present invention having a structure comprising an aggregate of substantially innumerable fibrils, the fiber has high strength, elastic modulus, and resistances to fatigue, hot water and chemicals and can be pulpified while keeping its excellent features such as high strength. The PVA fiber of the present invention cannot, even drawn to a high ratio, be readily whitened by virtue of its fibril-aggregate structure, and can hence be made still higher in performances. The PVA fiber can be obtained by adding to a PVA solution a relatively large amount of surface active agent, and wet or dry-jet-wet spinning the thus prepared dope solution into an aqueous alkaline coagulating bath.

摘要： A fibrous structure having a roughened surface and a process for producing the same are disclosed. Upon dying, the fibrous structure is greatly improved in color depth. In addition, it gives one a more scrooping feeling than silk does.The fibrous structure has surface irregularities whose structure is such that the distance between the adjacent projections is 0.01 to 0.7 micrometer and the area of the concave portions is 0.1 to 0.8 square micrometer in 1 square micrometer of the irregularities.The fibrous structure is produced by the steps of attaching fine particles to the fiber surface in an amount of 0.001 to 10 wt % based on the fiber, said fine particles having an average primary particle diameter smaller than 0.5 micrometer and being more inert than the fiber-constituting polymer base material to low-temperature plasma, and subjecting the fiber, to which said fine particles have been attached, to low-temperature plasma, thereby forming projections which are larger than the average primary particle diameter.
