Spongre Silk. A knitted fabric made from the waste or sweepings of silk. It is made out of the husks, the butts, and the odds and ends of everything left around the floor of a silk mill by way of wastes or shoddies. The knitted fabric or article looks very much like a rough crash or low grade of cotton toweling, only it is knitted and of very light weight. It is used for draperies and underwear, and also to wipe silverware and machinery.
