3 Textile Sizing Industry Standards Have Been Revised.

Recently, the cotton textile standard annual meeting was held in 2019. The meeting deliberated and revised and adopted "acrylic acid sizing for textile warp sizing". "Textile yarn sizing polyacrylic acid slurry test method, determination of non-volatile content", "textile yarns sizing polyacrylic acid slurry test method viscosity determination" and other 3 textile sizing standards.

It is reported that the above 3 industry standards have been formulated for more than 5 years. According to the requirements of the Ministry of information industry standard revision plan, they are included in this year's standard revision work plan.

According to the introduction, polyacrylic size is one of the three main sizing agents in the textile sizing industry, and plays an important role in the process of replacing PVA sizing. However, due to the professional knowledge of chemical polymerization, chemical production and so on in the process of R & D, production and inspection, textile enterprises have some difficulties in product identification and related indicators inspection. In order to better standardize the acrylic acid sizing industry and enable the standard to better guide the development of the industry, the members and experts of the bidding committee have seriously discussed, revised and determined the index data and test methods in the standard so as to promote the healthy and sustainable development of the pulp industry. The next relevant standards will be reported to be approved, and it is expected to replace the old standards in 2020.
