CMC Printing Dyeing Grade

CMC (Carboxymethyl Cellulose) - Printing and Dyeing Grade

In the textile industry, CMC is mainly used as a sizing agent and printing paste.

1. CMC Printing and Dyeing Grade: Used as a textile sizing agent, CMC's stable properties and good film-forming ability give it a high affinity for cellulose yarns, resulting in a high-strength film that reduces yarn skipping and breakage on high-speed looms. The film formed by CMC Printing and Dyeing Grade is water-soluble and biodegradable. As a finishing agent for fabrics, it can replace traditional starch pastes, significantly reducing the environmental pollution caused by re-sizing and desizing.

2. CMC Printing Grade (Textile Printing Grade): Used as a printing paste, primarily acting as a thickener, emulsifier, and suspending agent. CMC for printing and dyeing does not readily react with reactive dyes; it has good paste formation and is relatively stable in storage; it has high structural viscosity and good water-holding capacity, making it suitable for rotary screen, flat screen, and hand printing.
refined CMC Textile Dyeing Grade has high water solubility, minimal solution gelation, high transparency, excellent screen penetration and filtration performance, and stable viscosity, which can enhance the hydrophilicity and penetration of dyes, thereby improving the clarity of printing and pigment fixation. It also has good rheological properties, making it more suitable than sodium alginate for fine pattern printing on hydrophilic fiber textiles, and can also achieve good economic benefits.

Core Advantages

1. Superior Solubility and Stability

① Rapid, Lump-Free Dissolution: The unique formula significantly improves upon the clumping and dispersion issues of traditional CMC. It dissolves rapidly in both hot and cold water, producing a clear, transparent solution free of white particles and fibrous residue, greatly improving preparation efficiency.
② High Long-Term Storage Stability: CMC Textile & Dyeing Grade exhibits excellent resistance to biodegradation and mold growth. The solution viscosity remains stable over the long term, preventing rancidity and ensuring batch-to-batch consistency.

2. High Purity and Superior Application Performance

① Ultra-High Purity, Extremely Low Impurity Content: Through a proprietary purification process, impurities in the raw materials are effectively removed, resulting in high purity and significantly improved light transmittance, making it particularly suitable for high-end applications requiring high transparency.
② Significant Thickening and Stabilizing Effect: Textile Dyeing & Printing Grade CMC possesses excellent thickening, suspending, and emulsifying capabilities. It has a wide and stable viscosity range and effectively forms a protective colloid, preventing component stratification and precipitation, exceeding industry standards.

3. Outstanding cost-performance advantage: While providing performance that surpasses that of comparable products, CMC in Textile Printing maintains a highly competitive cost thanks to its optimized production processes, bringing customers a high return on investment.
 

FAQ

1. Q: In which processes is CMC used in Textile Printing?
A: It is mainly used for warp sizing and printing paste to improve yarn abrasion resistance, reduce yarn breakage, and make printed patterns clear and well-defined.

2. Q: Is desizing easy? Will it damage the fibers?
A: Desizing is very easy. It can be easily removed with hot water or enzymatic hydrolysis without damaging the fibers. The waste liquid has a low COD value, meeting environmental protection requirements.

3. Q: Can you provide technical support?
A: Yes. Our technical team can provide selection advice and process guidance for different yarn counts and printing processes to ensure smooth production.
