A reusable permeable dispenser for dispensing solid or semi-solid fabric conditioning agent which can be attached to a machine dryer drum or tumbles loosely in the dryer, comprising a flexible permeable container comprising a composition of a quarternary ammonium anti-static agent, a polyalkylene oxide compound, and silicone dioxide which has a substantially constant release rate regardless of dryer operator temperature.

Treatment of fabrics in machine dryers using treating means containing

Methods of warewashing utilizing a solid rinse aid, and the solid rinse aid which comprises a surfactant and urea, and preferably a dispensing rate adjusting additive, are disclosed.

Solid rinse aids and methods of warewashing utilizing solid rinse aids

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. The fabric-conditioning agent comprises a fabric conditioner, a softening point modifier, and a viscosity modifier. 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.
