Sodium carboxymethyl cellulose
1. Textile Warp Sizing
In recent years, the textile industry has made extensive use of Sodium carboxymethyl cellulose as the sizing agent instead of grain. Practices have proven that sizing with Sodium carboxymethyl cellulose not only saves a lot of grain and oil but also is far superior to starch and animal glue. In the warp of cotton, silk, wool, chemical fiber, synthetic fiber and blended fiber, Sodium carboxymethyl cellulose has the following advantages as the adhesive material.
1). Sodium carboxymethyl cellulose aqueous solution is clear, transparent, homogeneous and has favorable stability. Furthermore, its viscosity won’t be affected by mechanical force, so it has no change with pump cycle or stirring. It is stored in the size tank and not affected by the temperature or bacteria so can be taken at any time according to production needs.
2). Sodium carboxymethyl cellulose aqueous solution is full of viscidity and film-forming property. It can form smooth, wear-resistant, and flexible film on the surface of warp, bear the absolute strength, relative activity and friction of weaving machine, so it helps to provide favorable conditions for weaving more exquisite high grade fabric and high-speed production.
3). The yarn processed with Sodium carboxymethyl cellulose aqueous solution is easily dry and glossy, with a soft hand feel. Furthermore, desizing is very convenient without chemical treatment or the consumption of desizing agents.
4). The yarn count and fabric processed with sodium carboxymethylcellulose aqueous solution won’t get yellowing or mildewed, so it can dramatically reduce substandard goods with defective spots or greasy dirt, and avoid damages by worms or rats.
5). When starch is used as the size, it needs to have a full set of precise machinery and control instrument with complicated operations. However, using cellulose gum can greatly simplify the requirements, improve the sanitary condition of workshop, making the maintenance of mechanical equipment more convenient, and meanwhile enhance the production capacity of weaving machine.
