Sodium carboxymethl\yl Cellulose for textile printing use
Product Description
Sodium Carboxymethyl Cellulose (CMC) is a high molecular compound obtained from cellulose through chemical modification.
In textile printing and dyeing,CMCserves as a replacement for sodium alginate with active dye printing. Its color brightness, color
fastness, and feel are equivalento those of sodium alginate.CMChas a high paste rate,and the flm formed after diyingis tough
and easy to wash off compared to starch paste. Similar to sodium carboxymethyl starch paste, due to the presence of many
carboxylate anions in its molecules, it is suitable foranionic dyes.CMC paste generally withstands calcium and magnesiumions in
hard water.High-substitution and lowviscosity paste have strong electrolyte and acid resistance capabilties,making CMC widely
used in textile printing and dyeing processes.
Properties
1. Ultra-high degree of substitution, uniform distribution of
substitution groups, very few gel particles, ensuring no
defects in printing and dyeing.
2. Stable viscosity,good resistance to salt and alkali.
3.Good permeability ofthe solution,excellentflowability.
4.Good dyeing properties.
5.High eficiency in water washing after printing,good fabric
feel, comparable softness to sodium alginate.
6.Good waterretention, suitable for printing fine pattermns.
Itis non-reducing itself and does not react with active dyes.
