PROBLEM TO BE SOLVED: To provide a water-repellent reversibly air-permeable woven or knitted fabric having both of an air-permeable properties reversibly changing the air-permeability so as to rapidly correspond to the moisture change in the interior of clothes, and the water repellency preventing the invasion of water from the outside of the clothes.;SOLUTION: The water-repellent reversibly air-permeable woven or knitted fabric contains ≥30 wt.% swellable conjugate fiber obtained by conjugating a high-swelling component and a low-swelling component so as to form a side-by-side shape, and has a water repellent imparted thereto. The water repellency of the woven or knitted fabric is grade 3 or more, and the variation of of the air permeability of the woven or knitted fabric, represented by the equation: (variation of air permeability (%))=[{(air permeability (B) in wet state)-(initial air permeability (A))}/(initial air permeability (A))]×100 is ≥10%. The woven or knitted fabric is obtained by subjecting the woven or knitted fabric including the conjugate fiber obtained by conjugating the high-swelling component and the low-swelling component so as to form the side-by-side shape to water-repelling finishing, and subjecting the resultant product to rubbing finishing.;COPYRIGHT: (C)2006,JPO&NCIPI
