Abstract

The invention discloses an accelerator for carrying out alkali weight reduction treatment on polyester fiber fabrics, which belongs to the technical field of textile dyeing and finishing. Its composition and mass percentage are: 20-40% of double quaternary ammonium salt cationic surfactant containing polyoxyethylene group, 2-10% of non-ionic surfactant, and the rest is water. Due to the use of double quaternary ammonium salt cationic surfactants containing polyoxyethylene groups, on the one hand, the speed of the hydrolysis reaction has been improved; The mildness of the active agent improves the uniformity of weight loss. At the same time, after compounding the double-linked quaternary ammonium salt cationic surfactant containing polyoxyethylene group and the fatty alcohol polyoxyethylene ether nonionic surfactant, a synergistic effect will be produced, which can better reduce the surface tension and promote the lye The uniform penetration can make the weight reduction treatment more uniform, and can improve the handle and surface properties of the treated fabric.

Description

technical field [0001] The invention relates to a textile finishing agent, in particular to an accelerator for carrying out alkali weight reduction treatment on polyester fiber fabrics, and belongs to the technical field of textile dyeing and finishing. Background technique [0002] In recent years, the synthetic fiber industry has developed rapidly, and polyester fiber (polyester) is widely used in various textiles as the synthetic fiber with the largest output. In terms of performance, untreated polyester fabrics have defects such as hard hand feeling and easy to produce aurora. In order to solve the above problems, polyester fabrics are often subjected to alkali reduction treatment in dyeing and finishing processing, which is generally called "simulation". Silk" finishing. Alkali reduction treatment is to put the polyester fiber fabric into a concentrated alkali solution to undergo a chemical reaction. The alkali hydrolyzes the ester bonds in the polyester fiber macromol...
