Propylene series ester emulsion copolymerized size

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 size used in a water jet loom, in particular to a propylene-based ester emulsion copolymerization size. Background technique [0002] Acrylic esters have been widely used in the sizing of water jet looms since a very early time, and in the 1990s, first- and second-generation acrylic sizings were successfully formulated for this purpose. However, when the acrylic size is used for the size of the water jet loom, due to its high hygroscopicity, the weft insertion of the weft will be very difficult due to re-adhesion and poor opening of the sizing yarn, and it is easy to cause stoppage. In addition, because the film of the acrylic size is too soft, twisting, lateral movement and relaxation will occur during weaving, which will greatly reduce the quality of the fabric. On the other hand, this year, the demand for fabric products with international competitiveness has been increasing day by day, and the development of high-...

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.
