Japanese Patent JP3194431
Kind Code:
B2
Abstract:
The present invention provides a yarn composed of polytrimethylene terephthalate fibers, particularly polytrimethylene terephthalate multifilamentary fibers having a single-fiber size in a range from 1 to 56 dtex, which are collected together to have a total size in a range from 2000 to 22000 dtex. Further, the present invention provides a racket string composed of polytrimethylene terephthalate multifilamentary fibers having a single-fiber size in a range from 1 to 56 dtex, which are collected together to have a total size in a range from 7000 to 22000 dtex, and a musical instrumental string composed of polytrimethylene terephthalate multifilamentary fibers having a single-fiber size in a range from 1 to 56 dtex, which are collected together to have a total size in a range from 2000 to 14000 dtex. The yarn according to the present invention is high in strength, elastic recovery and stress-retaining ratio as well as excellent in water resistance, softness and homogeneity of yarn properties. The racket string according to the present invention can be set across a racket frame, for example, for tennis or other, games under a high tension, whereby high resilience is obtainable when the string is set, and maintained for a long time. Also, this racket string is excellent in impact resistance, durability and water resistant.
