Abstract
The longitudinal contraction of fibers of nylon in textile fabrics is caused by the application of a nylon textile fabric contracting agent. The agent comprises a mixture of ammonium or a metal nitrate; an acid selected from the group inorganic acid, organic carboxylic acid, sulfonic acid, and mixtures thereof; and a halo, carbocyclic aryl, carbocyclic aryloxy or alkoxy substituted aliphatic alcohol. The textile fabric is treated with the contracting agent and heated to a temperature of from about 200.degree. F. to about 400.degree. F., to initiate a longitudinal contraction of the treated portions of the nylon fabric. After removal of substantially all of the textile fabric treating agent, the textile fabric is dried, thereby completing the longitudinal contraction.
