Abstract

The invention relates to application of a moisture absorbing and sweat releasing finishing agent to polyester fiber materials. The moisture absorbing and sweat releasing finishing agent comprises the following raw materials: 5-10 parts of dimethyl terephthalate, 2-5 parts of N,N'-dyhydroxyl pyromellitic acid imide, 20-30 parts of propylene glycol block polyether, 25-100 parts of polyethyleneglycol, 13-40 parts of glycol and 0.2-1 part of a catalyst. In the finishing or dyeing process, a fiber material including the polyester fiber materials or composite materials of the polyester fiber materials and other fiber materials is added into a finishing bath or a dyeing bath, not only are the hydrophilicity, the moisture absorption and sweat discharge properties, the antistatic performance, the soil removal property and the soft hand feeling of the polyester fiber materials improved, but also the problem of low color fastness caused by thermal migration of a dye is effectively solved.

Description

technical field [0001] The invention relates to the application of a moisture absorption and perspiration finishing agent in polyester fiber materials. Background technique [0002] In the international textile and clothing trade, in addition to traditional practicality, aesthetics and durability, the quality requirements of products also attach importance to safety and environmental protection. The same is true for the color fastness of textiles. The molecules of dyes and heavy metals Ions, etc. are likely to be absorbed by the human body through the skin and endanger health. The other side will also stain other clothes worn on the body, or stain other clothes when washed together with other clothes. Improving the color fastness of textiles can undoubtedly avoid and reduce this risk. [0003] After finishing with functional additives, polyester fiber materials not only have the hygroscopic properties of cotton fibers, but also have antistatic properties, non-ironing proper...
