Use of Coarser Yarn

A fine looking twill may be produced with a somewhat coarser face yarn by using a five threaded face over a six-thread repeat. This is shown in the harness draft at Fig. 3.

In non-elastic fabrics there are available a variety of twill and satin weaves for the production of soft lustrous surfaces, but this is not so in elastic webs, as the contraction of the goods after weaving would produce a ragged, spongy surface. A float of three picks on the face is about the limit it is practicable to go on an elastic web, with few exceptions, and even this only in connection with fine picking.
