According to the different ratio of raw materials, it is divided into the following three products:
AA:MA | Weight average molecular weight | Viscosity mpa·s(25℃) | Calcium chelation force mgCaCO3/g | Calcium dispersity mgCaCO3/g | Monomer residue ppm |
7:3 | 60000-80000 | 2000-3000 | ≥360 | ≥260 | ≤3000 |
6:4 | 30000-50000 | 1000-1500 | ≥340 | ≥280 | ≤5000 |
5:5 | 10000-20000 | 500-1000 | ≥300 | ≥300 | ≤5000 |
Product features:
1. Pre-treatment process such as desizing and scouring as a chelating dispersant to eliminate the influence of metal ions such as calcium, magnesium and iron on product quality and processing; disperse suspended dirt and impurities to prevent dirt adhering to fabric fibers Re-attach to the fiber after being taken off during the washing process to improve the scouring and washing effect;
2. Oxygen bleaching process can stabilize the oxygen bleaching system to significantly improve the whiteness and eliminate the yellow spot phenomenon, which can effectively prevent the fabric from being damaged and broken in bleaching;
3. Dyeing, reactive printing or post-dyeing washing process, which is excellent in the dispersion and complexing ability of the dye, is beneficial to the uniform dyeing of the dye, and can also remove the floating color and prevent the dye from forming a stain;
4. The soaping process can suppress the formation of calcium precipitates in the equipment, and has certain protection for the fibers, thereby effectively preventing the fiber strength from being damaged.
