    摘要： Improved ultrafine sheath-core composite fibers and composite sheets composed of these fibers are disclosed. The composite fibers have a fineness of 0.0001 to 0.5 denier and comprises 10 to 70% of the core having a very high intrinsic viscosity within a specific range and being located at the center of the sheath and 90 to 30% of the sheath composed of a polyester copolymerized 1.5 to 8 mole %, based on the total acid component, of 5-sodium (or lithium or potassium) sulfoisophthalate and having a thickness of 0.04 to 2 microns. The composite fibers have a high strength and are dyeable with a cationic dye. When the composite fibers are combined with an elastic material such as polyurethane, suede-like artificial leathers having excellent softness, touch, feel and color can be obtained.

    摘要： The present invention relates to a novel method and apparatus for producing nonwoven fabrics. Generally, in production of nonwoven fabrics, in order to obtain a nonwoven fabric with a wide width, it has been impossible to obtain a uniform nonwoven fabric unless a large number of spinnerets ejecting fibers are installed in the width direction of the nonwoven fabric. The present invention relates to a novel method and apparatus for producing nonwoven fabrics capable of easily increasing the width of the fabric even when only few spinnerets are used. The method for producing nonwoven fabrics according to the present invention is characterized in that a group of fibers entrained with a high-speed fluid is ejected from a nozzle rotating around the axis of a substantially stationary cylindrical support as its rotational axis on the inner peripheral surface of the cylindrical support and is laminated thereon in the form of a web and furthermore, the web is resiliently pressed under a heating condition via a roller revolving on the inner peripheral surface of the cylindrical support around the revolutional axis which is the same as the rotational axis of the rotating nozzle and then, the web is taken up from the cylindrical support while it is slipped. In addition, the apparatus according to the present invention relates to an apparatus practicing the method.

    摘要： In a methd for producing a soft sheet material containing thinned fibers or filaments and a viscoelastic substance, the improvement comprising:(A) applying a mixture of a viscoelastic substance and a temporary filler to a sheet material containing thinnable fibers or filaments;(B) thinning the thinnable fibers or filaments forming said sheet material;(B') applying temporary filler to said sheet material or relocating said temporary filler applied previously at step (A) within said sheet material, whenever necessary;(C) applying a viscoelastic substance;(D) removing said temporary filler; and(E) napping the sheet, whenever necessary.In accordance with the present invention, it is possible to obtain a leather-like sheet material which, though soft, has good mechanical properties such as high abrasion resistance and high tear strength. A leather-like sheet material is produced which is free from deficiencies such as low abrasion resistance and tear strength even where the thickness is further reduced.

    摘要： A composite filament having an "islands-in-sea" type cross-sectional configuration having at least two kinds of islands, wherein the two islands are different in coefficient of contraction by at least 5%, or wherein one of the island components comprises a bimetal-type or eccentric-type composite filament. These island components are relatively well distributed throughout the sea component and the sum of the weight of the island components is greater than the weight of the sea component. Said composite filament may be made into a fabric as a filament of an ordinary denier. It is also possible to obtain a superfine fiber product being bulky or having an improved feel by superfining and heat-treating said filament thereafter.
