HT Fine Textile Chemical Auxiliary Agent

  Definition of scouring agent in textile   Scouring agent 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 agents 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 phenomenon with n...

The dyeing and printing of textile products need to be done in a certain way to remove impurities and oil stains on the cloth surface. This cooking process is often called scouring. And in the refining of various types of infiltration, emulsification, washing, dispersing, wetting function of chemical auxiliaries, called  scouring agent . During the refining process, the scouring agent is through its wetting effect, the weakened adhesion of the oil wax and the fiber in the fabric, and the gradually reduced interface, to make the oil wax fall off the fabric. At this time, the oil wax particles and water contact surface increased, forming a very unstable system, the surfactant in scouring agent has emulsifying and dispersing effect, which is easy to form micelles in water, and the oil wax wrapped in the micelle to form a comparatively stable system, which can prevent the oil grains from being deposited on the fabric. On the other hand, with the help of the ...
