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

摘要

A woven/knit fabric in which the porosity, upon humidification, reversibly decreases from the porosity in a dry state. The fabric comprises: crimped fibers (A) whose percentage crimp decreases upon humidification; and fibers (B) selected among non-crimped fibers or crimped fibers whose percentage crimp does not substantially change upon humidification. Crimped fibers (A) collected from this woven/knit fabric have a difference between the percentage crimp in a dry state DCf (%) and the percentage crimp in a humidified state HCf (%) (DC f-HCf) of 10% or larger. In the woven/knit fabric, the average RA of the rate of dimensional change in the warp (or wale) direction RP (%) between the humidified state and the dry state and of the rate of dimensional change in the weft (or course) direction RF (%) between the humidified state and the dry state (RA=(RP-RF)/2 (%)) is 5% or higher.
