HT Fine Textile Chemical Auxiliary Agent

The Introduction of dye fixing agents   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 fixing agent in 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 ...

  The main component of textile detergent   is a surfactant. The surfactant is a kind of organic compounds that contain both hydrophilic and lipophilic group in the molecular structure. Generally, surfactants are divided into two categories- ionic surfactants and non-ionic surfactants on the basis of whether the surfactant can break down into ions in the aqueous solution. The ionic surfactants can be divided into cationic surfactants, anionic surfactants, and zwitterionic surfactants.   The practice has proved that when washing the fabric only the anionic surfactants and non-ionic surfactants can play a positive and effective role in the fabric decontamination, therefore, these two surfactants have become the main material of textile detergents.   Textile Detergent should have good wetting, permeability, emulsifying, dispersibility, solubilization and foaming and defoaming performance. The combination of these properties is the washing performance of textile detergen...

  Time: 2017-07-13  Click: 5404 The pretreatment of textiles mainly refers to the treatment of fiber and textiles for dyeing or printing uniformity, and also for the improvement of whiteness and softness of textiles. Fiber properties, impurity components and textile methods should be considered in the pretreatment process of cotton fabric .   The purposes of pretreatment Through chemical and physical mechanical action, the natural impurities contained in the fibers are removed, and the slurry and oil stains applied in the textile processing are also removed, giving the fiber a full display of its high quality. Thus, the fabric has a white appearance, soft feel, and good permeability, which is to meet the use of demand, and to provide qualified semi-finished products for dyeing, printing, finishing.   The process of pretreatment The process of pretreatment varies as the quality of fiber 、 the processing of textile 、 quality of after processing and finished products. ...
