Problems solved by technology

Existing sizing also has a big shortcoming that is exactly that the sizing rate is very high in use, and the usual sizing rate is all high (such as polyester spinning reaches more than 3 to 3.5%). It will fall off during the weaving process, which will cause a lot of pollution to the environment, and the cost of processing is very high.

Abstract

The present invention relates to an acrylic ester emulsion copolymer slurry. It is mainly formed from acrylic acid slurry and styrene-butyl methacrylate copolymer, in which the described acrylic acid slurry includes the following components: acrylic ester, methacrylic acid ester, acrylic acid and methacrylic acid.

Description

technical field [0001] The invention relates to a sizing slurry used in a water jet loom, in particular to a propylene ester emulsion copolymerization slurry. Background technique [0002] Acrylic esters have been widely used in the size of water-jet looms since very early on. In the 1990s, the first and second generation of acrylic size were successfully formulated. But when acrylic size is used for the size that water-jet loom is used, because its hygroscopicity is big, can cause weft weft insertion very difficult because of re-adhesion, poor opening of sizing yarn, and easily cause downtime. In addition, because the film of acrylic size is too soft, twisting, lateral movement, and relaxation will occur during weaving, resulting in a significant decline in fabric quality. On the other hand, this year, the demand for fabric products with international competitiveness is increasing day by day, and it is constantly required to develop high-performance ...
