CMC in textile industry is mainly used as textile sizing and printing paste.
Sodium CMC in textile is used as sizing, because CMC has stable characteristics and good film-forming properties, it has a high affinity with cellulose yarn and makes the film have high strength, reducing “yarn skipping” and “broken ends” on high-speed looms . The film formed by CMC is water-soluble and has the characteristics of biodegradation. As a finishing agent for fabrics, it can replace traditional starch and greatly reduces the environmental pollution caused by fabric restarching and desizing.
“LinGuang” CMC Is Used As A Printing Paste
CMC in textile is used as a printing paste, mainly as a thickener, emulsifier and suspending agent.
- Printing and dyeing using CMC is not easy to react with reactive dyes, good paste rate, stable storage, high structural viscosity, good water retention, suitable for rotary screen, flat screen and hand printing;
- Refined CMC has a high degree of water solubility, very little solution gel , high transparency, excellent mesh penetration and suction filtration performance, thereby improving the clarity of printing and pigment fixation;
- Sodium CMC has good rheology and is more suitable for fine pattern printing of hydrophilic fiber textiles than sodium alginate;
- The actual printing effect is comparable to that of the latter;
- Sodium CMC can replace sodium alginate or be used in printing paste in combination with it, and can achieve great results with better economic benefits.
