Polyacetamide methylene maleate systhesis method

Abstract

The present invention relates to a polyacetamide methylene maleate synthesis method, wherein raw materials comprise 5-15 parts of acetamide, 5-15 parts of hexamethylene tetramine, 4-20 parts of maleic anhydride, 0.5-5 parts of an inorganic acid, and 60-85 parts of water, the method is performed in a reaction kettle, and the substances are poured into the reaction kettle according to the predetermined ratios in the formula so as to obtain a textile auxiliary agent. With the present invention, loom efficiency can be improved, the polyacetamide methylene maleate has characteristics of good compatibility with starch, high adhesion, high lubricity and high moisture absorption, yarn strength is effectively ensured, and an adhesion performance is substantially reduced.

Description

technical field [0001] The invention relates to a synthesis method of polyacetamide methylene maleate, which belongs to the field of textile pulp. Background technique [0002] The size coats the surface of the sliver with a layer of smooth, wear-resistant, flexible and strong size film, so that the winding fibers on the surface of the sliver are close to the backbone of the sliver, reducing the friction coefficient of the surface of the sliver, and at the same time allowing part of the size to penetrate Inside the yarn, it can increase the adhesion between fibers and increase the tensile strength of the yarn, so as to adapt to the high tension and medium beating-up in the weaving process, reduce the breakage and improve the efficiency. With the development of textile size until today, it has been unable to meet the requirements of various yarn varieties and sizing processes.

Problems solved by technology

With the development of textile size until today, it has been unable to meet the requirements of various yarn varieties and sizing processes. No matter how the traditional three size systems are optimized and combined, the defects are still very obvious, not to mention the green sizing is also Prompting that PVA will gradually withdraw from the ranks of textile sizing materials in the near future. Even if we temporarily put aside the factors of environmental sizing, we can no longer regard PVA as a "universal sizing agent", because in the sizing process of high-grade fine-count and high-density yarns, PVA The innate high strength of the starch has become a restrictive factor, which reduces the efficiency of the loom in many cases; however, adding a small amount of high-performance additives to ordinary modified starch and combining with a small amount of other size is an ideal size formula that can achieve high cost performance Although its comprehensive performance-to-price ratio is higher than that of polyacrylic size, its application is limited and there are environmental risks. Grafted starch has come all the way from controversy, good and bad, and prices vary. No matter the size manufacturer or the textile mill , has never established a win-win platform, especially sizing needs to provide a kind of lubricity, at the same time, it needs proper moisture absorption, and the most important thing is to ensure yarn strength without making the yarn between the yarns Bonding occurs, no matter what kind of separate slurry or additives, can not meet the above requirements
