    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.
