The names of the weaves indicate a method of interlacing threads rather than fiber content. Any fiber or combination of fibers may be used for any type of weave. Some weaves initially were associated only with one particular fiber, as in the case of taffeta and satin, which were made of silk; serge, a twill weave formerly restricted to wool; and denim, a twill originally made only of cotton. Present-day production includes nylon taffetas, cotton satins, silk serge, and denims of blended fiber yarns.
The introduction of synthetic fibers has led to research to determine the most desirable fiber content for specific applications. Required characteristics are achieved by use of various combinations and blends of fibers, methods of weaving, and dyeing and finishing processes.
