Abstract
A woven or knitted fabric, formed from two types of yarns different in self-elongating property upon absorbing water and capable of facilitating the air-permeability when wetted with water, is constituted so that a ratio A/B of a mean length A of yarns (1) having a high water-absorbing, self-elongating property to a mean length B of yarns (2) arranged in the same direction as that of the yarn (1) and having a lower water-absorbing, self-elongating property than that of the yarn (1) is adjusted to 0.9 or less.
Claims24
A woven or knitted fabric containing two types of yarns different from each other in a self-elongating property upon absorbing water wherein, when a test piece is prepared from the fabric in such a manner that said woven or knitted fabric is stabilized in dimension in the atmosphere having a temperature at 20° C. and a relative humidity at 65% and then cut into pieces of 30 cm long in the warp or wale direction and 30 cm long in the weft or course direction;
- and yarns (1) having a high water-absorbing and self-elongating property and yarns (2) having a low water-absorbing and self-elongating property and respectively contained in the test pieces satisfy the following requirement:
- A/B≦0.9
- wherein A represents a mean length of the yarns (1) having high water-absorbent and self-elongative property and B represents a mean length of said yarns (2) having low water-absorbing and self-elongating property, the yarns (1) and (2) being arranged in the same direction as each other in the test piece and picked up from the test piece;
- the length of the respective yarn being measured under a load of 1.76 mN/dtex when the yarn is a non-elastic yarn having an elongation at break of 200% or less or under a load of 0.0088 mN/dtex when the yarn is an elastic yarn having an elongation at break higher than 200%, and whereby the air-permeability of said fabric increases when wetted with water.
