    摘要： PURPOSE: Polyvinyl alcohol type binder fiber is characterized by having under 30% of cross-section circularity, over 100% of a degree of swelling in water of 30deg.C and under 20% of a degree of dissolution. The polyvinyl alcohol type binder fiber is used in manufacturing high strength paper or non-woven fabric even under low-energy dry conditions such as a high speed drying method like a hot air drying method or a low temperature drying method like a multi-cylinder method. CONSTITUTION: Polyvinyl alcohol type binder fiber has under 30% of cross-section circularity, over 100% of a degree of swelling in water of 30deg.C and under 20% of a degree of dissolution. The polyvinyl alcohol type binder fiber has a flat cross-section. The PVA binder fiber is obtained by using a resin copolymerized 0.1-15mol% of one selected from the group containing carboxylic acid group, sulfonic acid group, ethylene group, silane group, silanol group, amine group and ammonium group. Paper or non-woven fabric contains 1-50%by mass of the PVA binder fiber.

    摘要： PURPOSE: High-absorbent polyvinyl alcohol(PVA) fibers and non-woven fabric comprising the same are provided, which PVA fibers have high water absorbency and good strength and elongation properties, and from which fabrics containing the fibers can be readily prepared. CONSTITUTION: The cross-linked polyvinyl alcohol fibers prepared from a water-soluble polyvinyl alcohol satisfy the following requirements: (1) a water absorption in water at 30 deg.C ranging from 10 to 100 times the weight of the fibers; (2) a fiber diameter in water at 30 deg.C as a result of absorbing water ranging from 2 to 10 times the diameter of the fibers not having absorbed water; and (3) a melting point ranging from 160 to 220 deg.C, and a heat of fusion ranging from 40 to 100 J/g.
