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： The invention relates to a woven fabric and more particularly to a woven fabric having a velvety appearance. At least either warp yarns or weft yarns in the fabric comprise conjugate fibers having a cross sectional configuration such that the flatness is 3.5-15.0. Conjugate fibers representing more than 35% by weight of the conjugate fiber content of the fabric at portions other than formation points of the fabric have an angle of inclination of 45.degree.-90.degree. relative to the surface of the fabric. The floating distance between the formation points of the fabric covers a length of more than 1/4 of the pitch of the twist in the conjugate fiber.

摘要： Provided are napped fabrics with naps comprising a tapered fiber of a sheath-core polyester fiber with the sheath component having larger alkali hydrolysis rate than the core component, the core of the tapered fiber being exposed at its end part and having smooth surface, the sheath of at least the tapered part having minutely roughened surface. The napped fabrics are of high quality, having good hand and excellent color developing property without unnatural luster such as dark fading or white appearance and being difficult to soil, and are hence markedly suited for car seat cover.
摘要翻译：提供的是具有绒毛的起绒织物，其包含鞘芯聚酯纤维的锥形纤维，其鞘组分具有比芯组分更大的碱水解速率，锥形纤维的芯在其端部暴露并具有光滑表面，护套至少具有微小粗糙表面的锥形部分。起绒织物质量好，具有良好的手感和优异的显色性，不会发生黑色褪色或白色外观等不自然光泽，难以弄脏，因此显着地适用于汽车座椅罩。
