Textile Grade CMC

CMC can form a sheet which is firm, strong with a certain soft and wear resistant, and make itself stick well with the fiber surface. In addition, it gives the chaine sufficient elongation characteristics, increases the textile strength in the process of manufacturing, enhances the production efficiency and takes thickening effect as well. It can be widely applied in the textile industry such as warp sizing, textile printing and fabric finishing etc.

1. Application in warp sizing

After starching with CMC and drying, it can form a sheet which is firm, strong with a certain soft and wear resistant, and make itself stick well with the fiber surface. In addition, it gives the chaine sufficient elongation characteristics, increases the strength of the chaine, and reduce the dusting-off rate. CMC which is applied in textile will show the advantages as follows:

*Green products, eco-friendly, and full biodegradation;

*Easy pulping, no heating up and boiling down, and can be dissolved by cold water. Low carbon and energy saving;

*No gel sedimentation, and no crusting, no foaming inside the size vat and pipe;

*Temperature resistance, antibiosis, and stability of size viscosity;

*Easy dividing yarn and no bonding even in the high humidity weave workshop;

*Tough and wear resistance of the size sheet; enhance the weave efficiency, and reduce the yarn breakage to the minimum;

*Without enzyme desizing, and the gray cloth can be scoured or decolorized directly.

2. Application in textile printing

CMC, with the ultra-high degree substitution, can be used as the thickener in various textile printing color paste, and it has the excellent anti-acid and anti-salt ( that is, electrolyte endurance). The viscosity is stable after making up the thickener and printing color paste, and it can fully replace the high quality alginate. The advantages of product are listed as follows:

*Good hygroscopicity, increase the consistent color rate, and enhance the vividness;

*Good Penetration. Deep color absorption and easy off the work intensity for textile embossing;

*Excellent rheoloty, and keep the printing smooth;

*High solubility, high transparency, little gel and good filtrability;

*Good stability of viscosity, water-retention and net permeability

*Easy for desizing, and soft texture.

3. Application in fabric finishing

Paint the CMC aqueous solution on fabric, and then after the acetic acid treatment, it can be produced a special fabric with airtight and water proof. Treat the fabric with CMC aqueous solution first and treat with the easy decomposition of quaternary ammonium salt, then after drying, burnishing and heating at the appropriate phrase, and it can form a waxy fabric which is insoluble in coating.
