HT Fine Textile Chemical Auxiliary Agent

  Definition of scouring agent in textile   Scouring in textile refers to  a large number of auxiliaries with functions of emulsifying, penetrating, washing, dispersing and wetting in the scouring process before dyeing and printing, in order to remove oil stains and impurities from the textile fibers. The common scouring chemicals  include sizing agent, lubricating agent, oil stains agent, alkali-resistant agent, mercerizing agent, wax removing agent, penetrating agent and so on. The required property of scouring agent varies depending on materials, fabric structure, stains and applications.   Scouring agent is a non-toxic, tasteless, pollution-free white powder, soluble in water whose aqueous solution is alkaline, capable of cleaning, emulsification, dispersion, wetting, penetration and the pH buffering. It belongs to the inorganic alkali products, easily hygroscopic when placed in the air, sometimes there existing a little bit block, which is a normal phenomen...

The overcoming method (1) To strengthen the pre—treatment of textile The oil or greasy dirt contained on the fabric has a greater affinity for synthetic fibers, such as hydrophobic polyester so that it is not suitable to be washed. Especially before setting, the oil seeped into the fiber and made it difficult to wash. Fabric should be cleaned before desizing , scouring, bleaching, etc. For some fabrics containing a bit more polyester and other chemical fiber components, scouring and washing procedures should be adopted. And highly efficient  scouring in textile  and washing equipment must be selected. However, after washing, you must wash the  textile auxiliaries ; otherwise it will easily form tar with dyes and to make textile dirty. (2) To prevent dye condensation firmly (a) To select less condensed dyes under the dyeing conditions b)  To use leveling agent or dispersing agent with excellent properties. When disperse dyes in high temperature to be dyeing, to add pr...
