Abstract
A narrow woven stretch fabric is formed from bare elastomeric warp threads separated by high shrink warp threads and from a high shrink weft thread. The edge elastomeric warp threads are loosely wrapped with heat set yarn. These edge threads, which are under the same tension as the other elastomeric warp threads, are wrapped between the supply and the loom. The weft thread is interwoven at a low weft per inch and the fabric is heat treated to shrink the non-elastic high shrink threads and corrugate the elastomeric threads without heat setting. The wrapping device and the surface feed rollers for the elastomeric threads are driven by the loom drive at appropriate speeds.
Claims7
A narrow woven fabric comprising:
- a plurality of shrunk non-elastomeric warp threads;
- a plurality of bare elastomeric warp threads separated by said shrunk warp threads;
- a pair of elastomeric threads forming the edge warp threads, each of said edge warp threads having a loosely wrapped yarn thereon which was heat set before being wrapped about said edge warp threads for increasing the holding of said edge warp threads without modifying the diameter of said edge warp threads;
- and
- a shrunk non-elastomeric weft thread.
