Abstract
Silk fabrics are widely used as high quality cloth, interior, quilting and bedding materials because of having excellent touch, drape, resilience and low specific gravity characteristics. But, many waste silk materials are produced during the reeling, spinning, weaving, dyeing and finishing processes. From this fact, the recycle of waste silks is interested in studying for the application of industrial textile materials such as filter, oil absorbent and wound protector. Thus, this research has surveyed the decolorizing and carding characteristics in order to recycle the colored waste silk materials. As the results, the carding condition of waste silk fabrics was optimized with different fiber lengths and curding passage. In addition, the fiber failure mechanism from the wasted silk microdamage caused by carding process was investigated. Also it was found that longitudinal and transverse cracks, abrasion and pilling were formed on the surface of wasted silk fibers.
