Summary:FIELD: textile industry. SUBSTANCE: process includes (i) desizing in presence of oxalic acid (0.5-0.8 g/l), enzyme-containing preparations Aquasim 240L and Viscosim L (0.5-0.8 and 0.2-0.5 g/l, respectively), and moistening agent; (ii) two stages of high-temperature whitening with intermediate low-temperature whitening in aqueous alkali-peroxide solution; and (ii) acidification during 15-20 min. EFFECT: decreased process duration, improved environmental safety, and increased capillarity and strength of fabrics. 2 ex
