  • Woven/knit fabric with reversible air premeability and production process thereof
    Patent number: 8722552
    Abstract: This woven/knit fabric contains composite yarn comprising a multifilament yarn A2 and a multifilament yarn B2, which satisfies the following conditions (1) to (3): (1) the ratio (WA2/DA2) of the yarn length of the multifilament fiber A2 during absorption of moisture and humidity (WA2) to the yarn length of the multifilament yarn A2 under conditions of 20° C. and 65% humidity (DA2) is 1.02 to 1.30; (2) the ratio (WA2/DB2) of the yarn length of the multifilament yarn A2 during absorption of moisture and humidity (WA2) to the yarn length of the multifilament yarn B2 under conditions of 20° C. and 65% humidity (DB2) is 0.9 to 1.1; and (3) the drying shrinkage stress (DS value) of the multifilament yarn A2 is 0.08 cN/dtex or more.
