Three pages from Posselt's Textile Journal, November 1921, on the chemical analysis and testing of cloth. It covers determining size and finishing matter in cotton cloth, analyzing sizing compositions, and diagnosing stained, mildewed or tendered (weakened) goods. It also gives laboratory tests for cotton bleached for guncotton, and begins a section on silk thread finishing and finishing of pure and half-silk fabrics. The pages open with the end of an unrelated article on boiler houses.
