The silk fabric is a silk-like fabric, and generally refers to silk, including mulberry silk, tussah silk, castor-oil plant silk, cassava silk, and the like. It is a rather expensive surface fabric, widely used in clothes and furniture, and is famous for uneasy care and comfortable ventilation. Its skin-friendly property is incomparable with all other fabrics. The silk fabrics are divided into 15 categories according to fabric weave, warp and weft combination, processing technology and silk varieties of silk surface expression shapes. The other major categories are based on the ground structure except the patterns and the ground structure of the yarns, the threads and the velveteens. Each large silk-like surface can have plain (scouring, bleaching and dyeing) or flower (weaving and printing) expression.
