A composite desizing aid

Abstract

The invention discloses a composite desizing aid. The components are in parts by weight, 20-25 parts of hydroxypropyl acrylate, 10-18 parts of silicate, 5-7 parts of chelating dispersant, 6- 10 servings. The composite desizing aid of the present invention adopts the combination of chelating agent, hydroxypropyl acrylate and silicate, etc., which can not only consume the metal ions produced in the desizing process, but also avoid the formation of precipitates. It can also remove the pectin in the desizing solution. The desizing rate and capillary effect of the fabric have been improved, and with the removal of metal ions in the pectin, the binding force of other impurities in the hydrophobic network layer of the pectin skeleton has decreased, and it has been successively processed. , which can be further removed by washing with water, so as to obtain the ideal finishing effect.

Description

technical field [0001] The invention relates to a desizing aid, which belongs to the field of printing and dyeing. Background technique [0002] In textile printing and dyeing technology, in order to obtain better performance of the fabric, various auxiliaries are usually used to treat the fabric. In the pretreatment of fabrics, in order to speed up the speed of pretreatment and improve the quality of pretreatment, some auxiliary agents are usually added. With the development of auxiliary agents, people began to use chelating agents in the pretreatment and dyeing process of fabrics. However, due to the immature selection and application technology of chelating agents, many side effects occurred. In the desizing process of pretreatment, chelating agents are rarely used, and alkalis are mostly used as desizing aids. Precipitation is easy to occur during desizing, which affects the dyeing effect of the sequence. Contents of the invention [0003] The technical problem to be...

Problems solved by technology

With the development of auxiliary agents, people began to use chelating agents in the pretreatment and dyeing process of fabrics. However, due to the immature selection and application technology of chelating agents, many side effects occurred.

In the desizing process of pre-treatment, chelating agents are rarely used, and alkalis are mostly used as desizing aids. Precipitation is easy to occur during desizing, which affects the dyeing effect of the sequence.
