Abstract

The invention discloses a low-temperature pretreatment auxiliary with easiness in biodegradation and for cotton fabric. The low-temperature pretreatment auxiliary comprises components in percentage by mass as follows: 15%-30% of N, N'-DTM 8, 5%-15% of alkyl glycoside as a nonionic surfactant, 5%-10% of low molecular weight sodium polyacrylate, 2%-5% of inorganic salt and the balance of water. According to the low-temperature pretreatment auxiliary, Gemini surfactant N, N'-DTM 8 is taken as the main component of the pretreatment auxiliary, the surface activity is higher than that of a general surfactant, so that the wetting and washing effects of a scouring agent are enhanced; alkyl polyglycoside as the nonionic surfactant is adopted for compound, the compound beneficiating function is achieved, and the treatment effect is further improved; the used surfactant is good in biodegradability, accordingly, the biodegradability of pretreatment waste water can be improved effectively, the treatment difficulty of dyeing wastewater is reduced, energy conservation and emission reduction are promoted, and requirements for ecological textile processing and environment protection are met.

Description

Technical field [0001] The invention relates to textile dyeing and finishing processing technology, in particular to a low-temperature pretreatment auxiliary agent for cotton fabrics that is easily biodegradable, and belongs to the technical field of textile printing and dyeing processing. Background technique [0002] The purpose of textile pretreatment scouring and bleaching is to remove natural impurities such as cotton wax, protein, cotton seed hulls, pectin, etc. on cotton fabrics, and the slurry applied during weaving, as well as impurities contaminated by the fabric during processing, and through oxidation or The pigment is reduced and taken out, so that the fabric has a good appearance and internal quality. The pre-treatment process is a complex chemical and physical process of textiles at a certain temperature, using alkali, oxidizing agent and pre-treatment assistants. It includes processes such as infiltration, expansion, emulsification, dispersion, chelation, and deco...
