ECOLOGICAL PROCESS FOR FINISHING TEXTILE MATERIALS OF ARTIFICIAL CELLULOSIC FIBERS WITH CONTENT OF NON-ENCAPSULATED PHASE-CHANGE MATERIALS IN ADMIXTURE WITH COTTON FIBERS

摘要

The invention relates to a process of finishing textile materials of artificial cellulosic fibers with content of non-encapsulated phase-change materials in admixture with cotton fibers. According to the invention, the process consists in treating the textile supports in two distinct baths, without intermediary rinses between the treatment baths, where bath 1 contains 0.5...1% non-ionic surface-active product based on fatty alcohol-derivative polyglycol ether, 0.5...1.5% anionic active oxygen-donor product, 1...2.4% NaOH, 3.5...5% HO, at the temperature of 95...110°C, for 15...30 min, and bath 2 contains 0.1...0.4 ml/l of a neutralizing product for adjusting the pH to 7 and 0.2...0.4% catalase, at the temperature of 50°C, for 10 min, followed by dyeing in the same bath, after which the operations of final rinse and centrifugation are performed and, in the end, the drying on the tentering frame, at the temperature of 130°C, for 2...3 min, with a cooling run in the last zone of the tentering frame.
