Xanthan gum has important applications in the printing and dyeing industry. The following is an introduction to its applications and addition levels:
Applications
- As a thickener and adhesive: Xanthan gum can be used as a thickener and adhesive in textile sizing. It can increase the viscosity and stability of the sizing agent, thereby improving the sizing effect of textiles. In the printing and dyeing process, it can also be used to improve the stability and uniformity of the color paste, ensuring that the dye is evenly distributed on the fabric.
- As a suspending agent: Xanthan gum can be used as a suspending agent for dyes and pigments in the printing and dyeing industry. It can prevent the settlement of dyes and pigments, keep them in a suspended state, and is conducive to the dispersion, coloring, and color enhancement of pigments, making the printed patterns more vivid and the color fastness higher.
- Controlling the rheological properties of printing paste: Xanthan gum can control the rheological properties of printing paste, prevent the migration of dyes, and make the patterns clear. It has good compatibility with most components in the paste, and its own washing characteristics are also very effective, which is beneficial to the post - treatment process of printing and dyeing.
Addition Levels
The addition amount of xanthan gum in the printing and dyeing industry varies according to specific processes and product requirements. Generally, when used as a printing paste, the concentration of the printing paste is usually 1% - 2%, and the concentration of the sizing agent is 0.5% - 1.5%. When used as a suspending agent or thickener, the addition amount is usually in the range of 0.5% - 1.5%.
