摘要： PROBLEM TO BE SOLVED: To provide a bulky acetate multifilament yarn having a rich refreshing feeling and lightweight feeling, to provide a method for producing the acetate filament yarn and a woven or a knitted fabric thereof. SOLUTION: This acetate multifilament yarn simultaneously satisfies the following formulas: (1) 1.5 ≤ average single filament fineness (dtex) ≤ 6, (2) 84 ≤ total fineness (dtex) ≤ 200, (3) 80 ≤ number of interlaced spots (interlaced spots/m) ≤ 200, (4) 30 ≤ number of loops (loops/m) ≤ 50 and (5) 1.4 ≤ bulkiness (cc/g) ≤ 2.2. The method for producing the acetate multifilament yarn comprises carrying out a fluid interlacing treatment of a yarn spun in dry spinning of the acetate fibers and having 12-25% content of a residual solvent component capable of dissolving the acetate during a period between an outlet of a spinning stack to a winder at 1.5-3.0% relaxation ratio.

摘要： PROBLEM TO BE SOLVED: To provide a highly glossy cellulose acetate fiber excellent in color fastness to dyeing, having dry and cool feeling and a specific feeling same to a conventional acetate fiber.
SOLUTION: This cellulose acetate fiber has ≥20 of convex parts in a cross section in vertical direction to the fiber axis. The convex part is defined as the part protruding from outside of a polygon formed by connecting local minimum points to the inside direction of the fiber on a photograph of the cross section of the cellulose acetate fiber taken in a scanning electron microscope of 3000 magnification. The fiber preferably has glossiness ≥40 and if the glossiness is less than 40 the high gloss of the fiber can not be obtained.

摘要： PROBLEM TO BE SOLVED: To obtain the subject spinning dope which gives fibers having excellent dynamic characteristics when spun by a dry spinning method, by dissolving cellulose acetate having a specific acetylation degree and a specified viscosity in a non-halogenated organic solvent containing an ester-based solvent. SOLUTION: This spinning dope is obtained by dissolving cellulose acetate having an acetylation degree of 57.0 to 62.5% and a 6% viscosity of 80 to 300 mPa.s in a non-halogenated organic solvent (preferably an ester, and the content of the ester-based solvent in the whole solvent is 60 to 99.9 wt.%) containing an ester-based solvent (preferably methyl acetate) in a concentration of 5 to 50 wt.%.

摘要： PROBLEM TO BE SOLVED: To obtain both of an acetate yarn having a wet feeling and moist handle completely opposite to a dry touch, by reducing a cross-sectional shape of great number of unevenness of a conventional acetate yarn and the dry touch based on the cross-sectional shape, and its aggregate, and to provide a method for producing the yarn. SOLUTION: A cellulose acetate yarn 1 having >=45% acetylation degree is spun by a spinneret having plural spinning holes with a shape obtained by cutting off a part of a circle by two to four straight lines and an angle θ made between the two ends of the straight line and the center of the circle satisfying the equation 15 deg.

摘要： PROBLEM TO BE SOLVED: To produce a cellulose acetate conjugated fiber, having a touch feeling with extreme wetness, excellent in smoothness and suitable as a material, etc., for clothes by using respective specific spinning solutions for a core and a sheath components, carrying out the dry spinning under specified conditions and performing the saponification treatment of the resultant fiber with an alkali. SOLUTION: This cellulose acetate conjugated fiber is obtained by dissolving cellulose triacetate having 56.2-62.5% average acetyl content in an organic solvent, using the resultant spinning solution as a core component, dissolving cellulose diacetate having 48.8-56.2% average acetyl content in an organic solvent, using the prepared spinning solution as a sheath component, delaying the volatilizing and drying rates of the solvent in the spinning solutions, carrying out the dry spinning of the solutions into a core-sheath type and performing the saponification treatment of the obtained conjugated fiber with an alkali. Furthermore, the dry spinning is preferably carried out under conditions of =380m/min discharge linear velocity to provide the core-sheath type.
