Abstract

The invention belongs to the technical field of textile assistants and discloses a scouring agent for short-process pretreatment. The scouring agent contains the following components in parts by weight: 12-20 parts of sodium dodecyl benzene sulfonate, 1-4 parts of nonyl phenol, 0.9-10 parts of isoflurane, 1-1.5 parts of pethidine, 5-7 parts of acrylate, 10-15 parts of acrylonitrile, 12-14 parts of polymethylhydrosiloxane, 1-12 parts of diethylpropanediol and 90-150 parts of ethanol. The invention also discloses a method for preparing the scouring agent, application of the scouring agent in a desizing / scouring one-step process of cotton-polyester blended fabrics, in a desizing / scouring-bleaching two-step process of pure cotton fabrics and a cold pad-batch process of cotton-polyester blended fabrics, and further discloses a technological process of the process and a padding liquid formula. The scouring agent disclosed by the invention is rapid in penetration, high in emulsifying capacity, high in detergent washing capacity, high-temperature-resistant, oxidant-resistant, wide in application range and good in treatment effect.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of application of textile auxiliaries, and in particular relates to a scouring agent for short-process pretreatment. [0003] Background technique: [0004] Scouring agent is the process of removing natural impurities, contaminants and weaving pulp from various textiles such as cotton, wool, hemp, silk and synthetic fibers by chemical and physical methods, which is called scouring. Therefore, in a broad sense, chemicals such as acids, alkalis, oxidants, reducing agents and various surfactants added during the scouring process can be called scouring agents. However, in the textile industry, when it comes to scouring agents, it is mostly a narrow concept, mainly referring to various anionic, nonionic surfactants and appropriate additives, which are obtained through a certain proportioning method and have a cleaning effect. It is the main compound with synergistic effects such as penetration, emulsifica...
