摘要： PROBLEM TO BE SOLVED: To obtain the subject fiber having high non-circularity of the cross-section and excellent mechanical properties, heat-insulation, water-absorption, dyeing and weaving performance and fastness and useful for clothes, etc., by spinning a spinning dope containing a polyvinyl alcohol polymer and a specific amount of a specific phyllosilicate. SOLUTION: This polyvinyl alcohol fiber having a circular length ratio of the cross-section of >=0.85 and a ratio of (the diameter of the maximum inscribed circle)/(the diameter of the minimum inscribed circle) of the fiber cross- section of >=0.35 is produced by spinning a spinning dope containing a polyvinyl alcohol polymer and >=0.05wt.% (based on the polymer) of a swelling phyllosilicate having a cation exchange capacity of >=40mg/100g such as synthetic fluorine mica. Preferably, a fiber structure is produced by compounding the polyvinyl alcohol fiber.

摘要： PROBLEM TO BE SOLVED: To efficiently divide and attenuate fibers by charging the fibers and other compositions into a barrel and rotating a screw having protrusions. SOLUTION: Fibers and other compositions are charged into a barrel and a screw having many rodlike protrusions on the surface thereof is rotated to thereby apply a shearing force to divide and attenuate the fibers. Island-in-sea fibers comprising (A) a polyvinyl alcohol-based polymer and (B) a water- insoluble polymer, in which either of the components A and B is an island component and the other is a sea component, are preferred as the fibers. The polyvinyl alcohol-based polymer having >=80 mol% sponification degree is preferred as the component A and a cellulosic polymer or a polyacrylonitrile-based polymer is cited as the component B. Cellulose acetate and cellulose itself are cited as the preferred cellulosic polymer.

摘要： PROBLEM TO BE SOLVED: To obtain a reinforcing material and a hydraulic hardened product which can increase the toughness after occurrence of cracking as well as improve the fragility of the hydraulic substance by forming these material from a specific fibrous substance. SOLUTION: In order to obtain high bridging effects after occurrence of cracking, the use of a fibrous material of high tensile strength is required and a material of >=70kg/mm is used. The bridging effect is satisfactorily developed only with high tensile strength of the reinforcing material and a proper degree of bonding strength to the matrix are required. Thus, a reinforcing material having a relatively low pull-out resistance and high friction resistance, for example, a reinforcing material having 10-80kg/mm pull-out resistance and >=10kg/mm friction resistance is used. Therefor, a material of intrinsically high pull-out resistance, for example, polyvinyl alcohol fibers are controlled in its affinity to the matrix by applying or coating a hydrophobic substance such as an epoxy resin, a polyolefin resin or a fluorine compound to the surface. The application rate of the hydrophobic substance is controlled in a range of 0.1-10wt.%. The fiber used as a reinforcing material is a non-corrosive organic fiber.

摘要： PROBLEM TO BE SOLVED: To impart excellent alkali absorptivity, separate property, alkali resistance, kinetic characteristic and waterproof property by forming a separator by use of a poyvinyl alcohol fiber containing a specified quantity or more of a laminated clay mineral. SOLUTION: A polyvinyl alcohol fiber containing 0.01wt.% or more of a laminated clay mineral is used to form a battery separator. As the laminated clay mineral, for example, swelling fluorine mica is used. The polyvinyl alcohol fiber preferably has an alkali absorbing quantity (Aab) of 1.5 times or more of a quantity determined by the expression: Aab=(Wb-Wa)/Wa. In the expression, Wa represented the weight (g) after the polyvinyl alcohol fiber is refined at a temperature of 20 deg.C and a humidity of 60% for 2 days, and Wb represents the weight when the sample of Wa is dipped in a potassium hydroxide aqueous solution having a concentration of 35wt.% at 30 deg.C for 15min in a bath ratio of 1:100, and then centrifugally dehydrated for 10min under the condition of 1G. The tensile strength of the polyvinyl alcohol fiber is desirably 4g/d or more.

摘要： PROBLEM TO BE SOLVED: To facilitate the continuous quantitative feed of fibers, unify the dispersion of short fibers, and improve the reinforcing effect of sediment by using the fibers having a specific feature. SOLUTION: Slivers of 10000-10000000 denier paralleled with single fibers having the average fineness 100 denier or below and the average fiber length 20-200mm are used to manufacture short-fiber mixed sediment. The slivers have the fixed fiber quantity in the length direction, and they can be fed easily, continuously, and quantitatively. The feeding method of the slivers and the mixing method of sediment and fibers are not limited in particular. The continuous quantitative feed accuracy of short fibers is improved, the generation of fiber balls is prevented, and the dispersion of short fibers is improved.
