Abstract
A method of treating a woven fabric, this method including applying simultaneous and progressive heat and pressure to the fabric in such a manner that the yarn strands substantially across the width of the fabric are forced closer together thus imparting generally semi-permanent ease or stretch into the fabric, which is characterized and the method also includes affixing to the fabrics treated a selected interlining or interlining combination having inherent stretch whereby the semi-permanent ease or stretch imparted to the fabric is made substantially permanent is provided. Also provided is a fabric treatment apparatus having a heat applicator and pressure to a woven fabric and a transporter for affecting relative movement between the heat and pressure applicator and a fabric whereby passage of the fabric through the apparatus results in the yarn strands substantially across the width of the fabric being forced closer together thus imparting semi-permanent ease or stretch into the fabric, characterized and that the apparatus also includes means for affixing to the treated fabric an interlining and/or interlining combination having inherent stretch whereby the semi-permanent ease o…
