FABRIC COMPOSED OF REGIONS DIFFERENT IN STRETCHABILITY AND PROCESS FOR PRODUCTION THEREOF

摘要

A fabric composed of regions different in stretchability which has relatively high-stretch regions and relatively low-stretch regions, wherein the former regions are constituted of stretch fibers and nonstretch fibers and exhibit an extension higher than that of the latter regions; and a process for the production of the fabric which comprises applying an etching paste containing an etching accelerator by printing to arbitrary portions of a stretch base fabric and removing part or the whole of etchable fibers (a) present in the portions with an etching agent and which satisfies the following requirements (1) to (4): (1) the stretch base fabric is constituted of the etchable fibers (a), unetchable fibers (b), and unetchable fibers (c); (2) at least part of the etchable fibers (a) are made of a polymer soluble in the etching agent; (3) the unetchable fibers (b) are insoluble in the etching agent and exhibit stretchability; and (4) the unetchable fibers (c) are insoluble in the etching agent and exhibit nonstretchability.
