    摘要: Provided are a fibrillated regenerated cellulose fiber, and a fabric using the same, the fiber having a characteristic surface texture, softness, and a resilient feeling, being fibrillated by rubbing and tanning treatment in a wet state, and having an excellent surface texture and long-lasting feeling after being water-washed, thereby exhibiting high quality. Provided are: a regenerated cellulose fiber of which the surface is fibrillated and which has a degree of polymerization of 100-250, and a tensile strength of 1.0-3.0 cN/dtex (exclusive of 1.0 cN/dtex) at the time of drying; a fabric including the regenerated cellulose fiber as a constituent yarn; and a method for producing the regenerated cellulose fiber of which the surface is fibrillated, and the fabric including the regenerated cellulose fiber as a constituent yarn, the method comprising a step for modifying, in an acid solution, the regenerated cellulose fiber into yarn or fabric form, under the conditions of a temperature of 110-150 °C, a pH of 2.6-3.4, and a duration of 10-30 minutes.

    摘要: A hollow fiber membrane which is excellent in material separation performance and performance of removing high molecular materials in blood, represented by beta 2 microglobulin (molecular weight of 11,800 dalton) to suppress invasion of endotoxin fragments from a dializing fluid into a patient's body to provide an excellent biological compatibility when used in blood dialysis. The hollow fiber membrane has a speed of water permeability of 30 to 300 ml/m .hr.mmHg, film thickness of 5 to 50 mu m, pore diameter D1 on an inner wall surface, which is represented by 10 /=1.2D1, and the pore diameter continuously increases from the inner wall surface of the membrane toward an inner part thereof and continuously decreases from the inner part of the membrane toward the outer wall surface thereof, such that it has at least one maximum portion in the inner part of the membrane with a rate of increase ( rho 1) of the pore diameter in the inner wall layer and a rate ( rho 2) of decrease of the pore diameter in the outer wall layer, respectively, being 20 to 200 %. The hollow fiber membrane of the invention is manufactured by discharging a spinning solution composed of polymer and a solvent of the polymer from outside spinning ports on double annular spinning nozzles, discharging a hollow portion forming agent from inside spinning ports, and sequentially solidifying the spinning solution in two or more stage coagulation baths composed of a solution, which has a faster coagulating speed than water.

    摘要: An optical fibre of sheath-core structure has for its core a copolymer which includes an aliphatic N-substituted maleimide as a monomer unit, and preferably methyl methacrylate as a further monomer unit. Such optical fibres have high light transmittance, good mechanical characteristics and an excellent heat-­resisting durability.
