HT Fine Textile Chemical Auxiliary Agent

  Definition of non formaldehyde dye fixing agent At present, color fixing agent can be divided into cationic fixing agent, resin type fixing agent (containing formaldehyde resin type fixing agent containing polyamine resin type fixing agent) and cross linking reaction type fixing agent.   The mechanism of color fixing agent which can improve the dyeing fastness of dye solution on the fiber is through   (1) the quaternary ammonium salt or tertiary amine salt in color fixing agent molecules, when in acidic medium, relying on a combination of anionic ionic bond strength of cationic and anionic dyes in the structure and form insoluble fiber deposition in the inside and outside the lake;   (2) reactive binding groups in color fixing agent molecules covalently links active group covalent bond in fibers and dyes;   (3) Fabric which is treated by color fixing agent in the drying process, the reactive binding group on the color fixing agent molecules associate group age...

Fixing agent textile  is one of the important textile auxiliaries in dyeing and printing industry, which can improve the color fastness of dye in fabric. On the fabric, it can form insoluble colored material with dye, thus to improve the color of washing, perspiration fastness, and sometimes can improve its sun fastness. In recent years, with the development of science and technology, dyeing and finishing technology has also been significantly improved. Due to the expansion of international textile trade and the improvement of people's living standards and environmental awareness, it's more required of textiles comfort, clean and safety. Since the 1970s, Germany first launched the "Blue Angel" plan, the world's developed countries (Japan, the United States, etc.) have passed and implemented the related laws, regulations, and rules for the various indicators of textiles. Green textiles require that in the printing and dyeing process prohibit the use of carcinogenic...
