Textile Printing and Dyeing Grade CMC

Introduction

Jinsheng Sodium Carboxymethyl Cellulose CMC is widely used in printing and dyeing,it has higher cost performance compared with sodium alginate. With a higher degree of substitution, Sodium Carboxymethyl Cellulose CMC can replace most sodium alginate. Sodium CMC can act as the sizing agent for the warp sizing of fabrics including cotton, gloria, chemical fiber and blend.
The print paste of rayon fiber usually contains cleaning solvent with high boiling point, dye, water and enough thickening agents. Sodium CMC is the thickening agent as well as the emulsifying agent, so it helps to uniformly mix the dye with high boiling point cleaning solvent with as well as to stabilize the dye suspension and thus to prevent the occurrence of sedimentation and the formation of foam in storage. 

As printing thickener, Sodium CMC has the following features in the products. 
1). Excellent viscosity stability; 
2). Good distribution uniformity of DS (degree of substitution); 
3). Good fluidity of solution in the color paste system; 
4). Higher washable performance in the washing process after printing and dyeing.

Function of CMC in Food Industry:

1. Good stability of viscosity compared with natural printing paste.

2. Good fluidity, even dyeing.

3. Good distribution uniformity of degree of substitution reduce the reaction with reactive dyes.

4. Low gel.

5. Good color yield.

6. Good property of holding water , suitable to printing fine pattern.

7.Good capability with other printing paste.

Packing and Storage
