摘要

Improvements in the manufacturing process of an elastic fabric from non-elastic yarns and fabrics thus obtained, characterized by incorporating a first operative form in which, in the same step as the normal weft yarns, or the reinforcing weft, we insert weft threads of a material such that it can be made to disappear further, for example by means of carbonization or incineration, these supplementary threads being preferably of a relatively thick gauge in order to force the warp to take a significant contraction; the fabric is then subjected to a fixing treatment intended to maintain the warp yarns with their sinuous configuration due to the great contraction, then proceeding to the elimination of the supplementary threads of the weft, for example by means of carbonization or incineration, so that a fabric with a high longitudinal elasticity is obtained.
