WOVEN/KNIT FABRIC INCLUDING CRIMPED FIBER AND DECREASING IN POROSITY UPON HUMIDIFICATION, PROCESS FOR PRODUCING THE SAME, AND TEXTILE PRODUCT

摘要

A woven or knitted fabric with a air space which is reversibly decreased by wetting with water compared to its dry state, comprises crimped filaments A whose percentage of crimp decreases upon wetting with water, and filaments B selected from among filaments with no crimps and crimped filaments which undergo substantially no change in percentage of crimp upon wetting with water, wherein the difference between the dry percentage of crimp DC f (%) and the wet percentage of crimp (HC f ) (DC f -HC f ) of a crimped filament A taken from the woven or knitted fabric is at least 10%, and the average value RA between the change in dimensions RP(%) of the woven or knitted fabric in the warp (or wale) direction when wet and when dry, and the change in dimensions RF(%) in the weft (or course) direction when wet and when dry (=(RP-RF)/2) (%) is at least 5%.
