Â Non-ionic penetrants are mainly used in the pretreatment of various fibers such as cotton, polyester and cotton ; the elimination of red-light fixing agents can effectively improve the color fastness of dyed fibers; chelating dispersants have many uses, such as desizing, refining, The bleaching process. Â Non-ionic penetrant The main ingredient is a mixture of special alkyl polyglycol ethers with a transparent liquid appearance. Role: mainly used for pre-treatment of the various fibers of cotton, polyester and the like which; An active, dispersion dyes remove loose color printed fabric can be treated at a low temperature, to avoid fabric staining white ground, the general amount of 0.1 to 0.5 g / l. The oil on the finished product can be scrubbed, and is particularly effective for degreasing spots on finished silk products.

It can effectively improve the color fastness of dyed fibers, and can particularly improve the fastness of deep-colored fabrics. The feel of the fiber is small, and it has a wide adaptability to the equipment. Â Chelating dispersants The main ingredient is organic acid complexes, the appearance of colorless transparent liquid. Uses and characteristics: Excellent chelating and dispersing ability, chelating value is greater than or equal to 250mg/g . Acid and alkali and electrolyte stability is good. With a variety of uses, such as desizing, refining, bleaching and dyeing process. It also prevents impurities from re-precipitating, making the machine less susceptible to scaling. According to the quality of the water and the amount of use. It can be mixed with glycolic acid, PAA , BTA and molybdate copolymers. Classic sunglasses are never outdated.
