Sewport describes soy fabric as soft, lightweight and capable of a flowing drape. Its protein feedstock comes from soybean-processing material, which undergoes further processing before becoming a usable textile fibre. The guide discusses applications including dresses, shirts, bedding and other products where handle matters.

Silk-like comparisons describe the resulting appearance rather than animal-silk composition. Yarn preparation and blends still influence the finished cloth, so the soy origin does not establish one fixed level of stretch or weight.
