<p>The lengthwise and crosswise stretchable cloth according to the present invention contains 30 wt % or more of conjugate polyester fibers obtained by the bicomponent spinning of polyethylene terephthalate (component A) containing 1.5 to 6.0 mol % of a comonomer unit having a metal sulfonate group and either polyethylene terephthalate or polybutylene terephthalate (component B) and stretching the resulting fibers. The obtained conjugate fibers have a double refraction ratio of 90 x 10-3 to 195 x 10-3 and show, when three-dimensionally crimped, an elongation falling within the following range in the lengthwise and crosswise directions: 9 « ((L¿2?-L1)/L1) x 100 « 160, wherein L1 represents a vertical length of a 5-cm wide test sample with a given length when a 5-g load is imposed thereon, and L2 represents a vertical length of said sample when a given load - 240 g in case of non-woven fabric and 1500 g in case of woven or knitted fabric - is imposed thereon. The stretchable cloth of the specific conjugate fibers showing an elongation of 9 % or more in both the directions has a good hand, and shows excellent dyeability and heat-setting properties, thus being extremely effectively used as both clothing and industrial materials.</p> |
