Abstract
Abstract A process for making a fabric is used to produce bedding especially well suited for hospitals, nursing homes, jails, mental institutions, and the like. The process begins with a tightly woven taffeta or ripstop weave cloth made from fine nylon or polyester threads. First, one surface of the taffeta is coated with a urethane water repellent. Next, the partially finished product is treated by immersion in a bacteriostatic and fungistatic, a fire retardant, and an anti-static bath. The cloth is then cut and sewn into a desired, at least partially, finished product, such as a pillow cover or mattress ticking and can be vented as desired.
