Problems solved by technology
Many defoamer preparation manufacturers have only made corresponding defoamers for different types of products, but these have not been fully optimized and combined. Synergistic effect in application; (2) The triphenyl phosphate defoaming system used in starch has a foaming effect on the PVA system; (3) The extensive use of defoaming agents reduces the adhesion of the size to the yarn; (4) ) may cause mutual influence and even failure. Finally, defoamers must be added when cooking and using pulp. These problems have caused unnecessary waste of defoamers and even reduced the quality of the pulp itself. Sizing performance

Abstract
The invention discloses a method for preparing a textile sizing defoaming agent. Mainly aiming at different proportions of modified starch, modified polyvinyl alcohol (PVA), other synthetic size and surfactant in textile combined size, the proportion of A silicon paste material, dimethyl silicon oil, white carbon black and tributyl phosphate defoaming effective ingredient is adjusted, and the materials are dispersed in a saturated hydrocarbon solvent such as animal oil, vegetable oil or the like by a certain preparation process. The textile sizing defoaming agent is added at the early stage of preparation of commercial combined size, the size is boiled at the temperature of over 80 DEG C, the deforming agent plays a strong targeted long-time defoaming role in the size use process, and the consumption and use cost of the defoaming agent in the size are reduced to realize specificity of different combined sizes.
Description
technical field [0001] The invention relates to a preparation method of an antifoaming agent in textile sizing, and specifically relates to the application in the pre-addition of combined pulp, and exerts a strong and targeted long-term foam suppression ability in the process of pulp cooking and pulp use . Background technique [0002] In the process of textile sizing, how to eliminate the generation of foam is a matter of great concern to sizing technicians, especially after the popularization and application of steam sizing machines, textile mills have put forward higher foam suppression requirements for textile sizing additives . [0003] Some technical workers in the textile industry have carried out theoretical analysis and research on the mechanism of anti-foaming, and summarized the reasons for the foaming of textile pulp. For example, Hong Zhongqiu of the Shanghai Cotton Textile Industry Association, based on his long-term in-depth understanding of the production s...
