Product Description of Printing and Dyeing Grade Sodium Alginate Manufacturers

　　Industrial-grade sodium alginate is mainly used in printing and spinning industry, and industrial-grade sodium alginate products are also necessary products in papermaking and other industries. Qingdao Nanshan industrial-grade sodium alginate manufacturer, please read the following contents carefully:
　

　　Introduction of printing and dyeing grade sodium alginate products;

　　Printing and dyeing grade sodium alginate, also known as printing and dyeing grade sodium alginate, printing and dyeing grade kelp gum, printing and dyeing grade alginate, is a natural polysaccharide carbohydrate extracted from kelp. Industrial printing and dyeing grade sodium alginate is mainly used in food, medicine, textile, printing and dyeing, paper making, daily chemical industry and other products, as thickener, emulsifier, stabilizer, adhesive, sizing agent and so on.

　　Main uses:

　　Printing and textile industry

　　Printing paste

　　Printing and dyeing grade sodium alginate has been used for warp sizing, finishing sizing and printing sizing for a long time, but it is mainly used in printing sizing. Printing and dyeing grade sodium alginate is used as the color paste of reactive dyes, which has unique properties. The fiber reacts with reactive dyes to fix the dyes on the fiber, and the printing paste used in the dyeing process should not interfere with or participate in the chemical reaction bonding. If the color paste participates in the reaction, it will be fixed on the fiber, which will cause the dyed fiber to feel hard, brittle and bad color. When sodium alginate is used as printing paste, it does not affect the dyeing process of reactive dyes and fibers, and at the same time, the printed patterns are clear and bright, with high color supply and good hand feel. Sodium alginate is not only suitable for printing cotton, but also for printing wool, silk and synthetic fiber.
　

　　Industrial sodium alginate with medium viscosity and low viscosity is suitable for the requirements of color paste from screen printing to drum printing. In fact, it is stable to prepare printing paste with low viscosity sodium alginate, which makes it possible to prepare printing paste with high content, which can lead to dense film during drying and increase the coloring rate.

　　Other industries

　　Using water-soluble sodium alginate to replace part of rosin pulp dispersant or paper surface sizing can increase the smoothness of paper surface, adjust the absorption of printing ink, wax and oil, and improve the rubbing resistance of paper.

　　Negative electrode: covered electrode coating material mixed with sodium alginate, potassium alginate and calcium alginate can bond the negative coating and wet the coating material, so that it has enough plasticity in the extrusion process, and it is easy to burn into ash in the welding process to reduce splashing.

　　In addition, printing and dyeing grade sodium alginate can be used in resin coatings, rubber pastes, battery separators and water treatment. In agriculture, sodium alginate can be used as seed treatment, insecticide and antiviral material.
