1. Textile grade sodium carboxymethyl cellulose (CMC)
Sodium carboxymethyl cellulose (CMC) is made from natural cotton fibers, through etherification, purification and drying process. Sodium carboxymethyl cellulose (CMC) appears to be white powder or granules, with good water solubility, having the functions of thickening, stabilizing emulsifying and suspending in aqueous solution.
In the textile industry CMC is used as woof trimming agent replacing traditional starch paste material,which can reduce pollution of woof during sizing and desizing.At the same time,CMC can form a membrane on woof which reduces"drop woof" and "decollation" sign.CMC can be used as printing material for dye-trimming industry and it can improve hydrophilic force and osmosis force of dye material,making dying more even and reducing chromatism.
