<p>A woven fabric contains a wrapped yarn in warp or weft, or both of which the core is a non-shrinkable, pref. cotton, yarn whilst the wrapping yarn is a highly elastic yarn having a shrinkage of at least 10%, pref. at least 15%. The wrapping yarn is pref. a plain synthetic yarn which is wrapped around the core at high tension forming an open helix, i.e. in which adjacent turns do not touch. The wrapping twist is equal to the ratio of the number of threads per metre in the woven fabric to the number of threads in the design repeat. The wrapping yarn may consist of a covered elastomeric yarn. This process gives a light, open fabric with no size content in which warp and weft yarns have no tendency to slip w.r.t. each other. It has a novel handle, high dimensional stability, high strength and crease-resistance.</p> |
