Problems solved by technology

[0003] In the desizing process, generally do not choose to use high-concentration alkali, because in the case of using high-concentration alkali, first of all, the permeability of the entire working fluid will be poor at high temperature, which is not conducive to desizing and may easily cause desizing It is not clean, and secondly, ordinary desizing and refining agents will not be able to withstand such a high alkali, and problems such as floating and demulsification will occur

Abstract

The invention discloses a high-alkali resistance desizing refining agent and a preparation method and the application thereof. The desizing refining agent comprises the following components in percentby weight: 5-20% of an anionic surfactant, 0-30% of a zwitterionic surfactant, 0.2% of a defoaming agent, 5% of a cosolvent and the balance of water. The desizing refining agent can adapt to a high-alkali desizing raw material; alkali reacts with a sizing agent in the desizing process, and in the case of high alkali, the amount of the alkali in the same amount of a working liquid is larger and the amount of the sizing agent capable of reacting is relatively larger, so that more sizing agent can be desized, and the desizing efficiency is improved.

Description

technical field [0001] The invention relates to a highly alkali-resistant desizing and refining agent, a preparation method and application thereof, and belongs to the technical field of textile processing. Background technique [0002] Chemical fiber fabrics will be sized on the fiber surface during the weaving process. The main sizing material is acrylic pulp. The refining and desizing process is a complex physical and chemical process, which has the functions of penetration, dispersion, cleaning, and chelation. It usually involves two processes: (1) removing the size from the fiber; (2) dissolving the size in the aqueous solution to form a suspension to prevent it from sticking back to the fiber again. [0003] In the desizing process, generally do not choose to use high-concentration alkali, because in the case of using high-concentration alkali, first of all, the permeability of the entire working fluid will be poor at high temperature, which is not conducive to desizin...
