Textile-Grade CMC (Carboxymethyl Cellulose)

CMC is primarily used in the textile industry as a sizing agent and printing paste.

1. CMC is used as a textile sizing agent due to its stable properties and excellent film-forming ability. It exhibits high affinity with cellulose yarns, enabling the resulting film to achieve superior strength and effectively reducing issues like "jumping yarn" and "broken ends" in high-speed looms. Moreover, the sizing film formed by CMC is water-soluble and biodegradable, making it an ideal alternative to conventional starch-based sizing agents for fabric finishing. This not only minimizes the environmental impact of re-sizing and desizing processes but also significantly cuts down on pollution caused by these traditional methods.

2. CMC, when used as a printing paste material, primarily functions as a thickener, emulsifier, and suspending agent. It does not easily react with reactive dyes during printing and dyeing, exhibits excellent paste-forming properties, and maintains good storage stability. With its high structural viscosity and excellent water-retention capability, CMC is well-suited for rotary screen, flat screen, and hand-printing applications. Furthermore, the refined CMC forms solutions that are highly soluble in water yet produce minimal gelation, resulting in exceptional transparency, outstanding mesh-passing and filterability, and remarkably stable viscosity. This makes CMC particularly effective in enhancing the dye's hydrophilicity and penetration ability, thereby improving the clarity of printed patterns and ensuring superior pigment adhesion. Additionally, CMC demonstrates superior rheological properties, making it more suitable than sodium alginate for fine-pattern printing on hydrophilic fiber textiles. In practical applications, the printing results achieved with CMC are comparable to those obtained using sodium alginate alone, and CMC can even serve as a direct replacement or be blended with sodium alginate in printing pastes—offering significant cost advantages while delivering equally impressive performance.
