TEXTILE-ACCESSORY SUBSTANCE FOR PREPARING TEXTILE MATERIALS CONTAINING NATURAL FIBERS TO STAINING AND FINISHING Russian patent published in 1996 - IPC

FIELD: textile industry. SUBSTANCE: textile-accessory substance (TAS) has, wt.-%: acetaldehyde alkylpolyhydroxyethylene butylacetal with C₁₀-C₂₀-alkyl and hydroxyethylation degree 9-20 30-35; N-octadecylsulfosuccinoylaspartic acid tetrasodium salt 20-26; copolymer of maleic anhydride with styrene sodium salt at polymerization degree 6000-10000 0.5-5.0, and water - the rest up to 100. Properties of cotton and mixed fabrics after preparing with TAS: capillarity is 130-135 mm/h; desizing degree is 7-8 points, and whiteness degree is 80-85%. TAS is stable in solution at sodium hydroxide concentration 140 g/dm³. Surface tension (stalagometric method) of TAS aqueous solution at concentration 2 g/dm³ is 31-33 mn/m; foam-forming capability at TAS concentration 2.5 g/dm³ is 30-35 ml after 180 s. TAS is used in textile-finishing manufacture for preparing textile materials made of natural and mixed fibers for staining and finishing at stages of washing, desizing and whitening. EFFECT: enhanced quality of substance.
