Abstract: PROBLEM TO BE SOLVED: To obtain a woven or knitted fabric comprising a hollow structure yarn having both stretchability and a sense of lightness by elasticity of a spiral aggregate, by forming a hollow structure of cavity form by an aggregate of multifilament. SOLUTION: This woven or knitted fabric comprises a spiral multifilament aggregate obtained by twisting conjugate multifilament yarns in which the central part of the aggregate has a cavity structure in the length direction of yarns. The conjugate multifilament yarns are of a high shrinkage stress type, are usable as a composite yarn by combining the yarns with another yarn such as a false twist textured yarn. After the conjugate multifilament yarns are woven or knitted, the woven or knitted fabric is subjected to relaxing wet heat treatment to form a cavity structure at the central part in the longer direction of yarn.

Abstract: PROBLEM TO BE SOLVED: To obtain a woven or knitted fabric excellent in frosting resistance without deteriorating the original lightweight property and swollen touch of the woven or knitted fabric using hollow fibers. SOLUTION: Hollow fibers having a hollow rate of 20-50% are used for weaving or knitting yarns. The hollow fibers are placed in at least the surface part of the woven or knitted fabric, and at least one part of the hollow fibers are pressed to give a hollow rate of

Abstract: The present invention provides crimped yarns that comprise a conjugate multifilament yarn and make it possible to produce woven/knitted products having unique surface texture, dry touch, and stretchability; woven/knitted products comprising said crimped yarn; and production methods thereof. Said crimped yarn is a conjugate multifilament yarn comprising polyester polymer components and meets the following equations: Such a crimped yarn can be produced by subjecting a crimp-forming conjugate multifilament yarn to relaxation-heat treatment.
