  • Treatment of fabrics in machine dryers
    Patent number: 4098937
    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 reusable dispenser of solid or semi-solid fabric-conditioning agent is placed in the dryer drum and tumbled with the fabrics 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 cause the fabric-conditioning agent to soften and assist in its distribution over the surface of fabric with which it is brought into tumbling contact.
    Type: Grant
    Filed: July 12, 1976
    Date of Patent: July 4, 1978
    Assignee: Economics Laboratory, Inc.
