Abstract:
Sponge-textured thread is made from natural silk thread by subjecting the silk thread to conventional degumming operations, then to known operations of the conventional method of obtaining a sponge-textured thread; i.e., twisting, fixing by thermal or steam treatment and untwisting, and then placing the silk thread in a humid medium, which is preferably hot. If the humid treatment is effected after weaving or knitting, these must be very loose. After the degumming step the silk thread can be coupled to another thread of silk or other fiber.
