Abstract
Abstract A method of producing a relatively open air permeable glass fiber fabric for use in orthopedic casts, bandages and the like and comprising interlaced chemically desired glass yarns consisting essentially of filaments having an average diameter not greater than about 0.00021 inches. The fabric is formed by a method wherein sized glass yarns consisting of filaments of the above diameter are desized by forcing a treatment solution through the yarns while confining the yarns in wound package form. A coupling agent may also be applied to the glass yarns, and then the yarns are interlaced to form a fabric.
