Title: Treatment of fabrics in machine dryers

Abstract: Fabrics are treated in machine drying apparatus to reduce static electricity carried by the fabrics, soften the fabrics and improve other fabric properties. A sponge impregnated with a heat softenable solid or semi-solid fabric-conditioning agent is placed within the dryer drum and the fabrics are tumbled in the dryer thereby causing some of the fabric-conditioning agent to be transferred to the fabric. When the dryer is heated, the heat of the dryer helps the fabric-conditioning agent to soften and assists in its distribution over the surface of fabric with which the impregnated sponge is brought into tumbling contact.
