Scouring is a very important process in the pre-treatment process of printing and dyeing. The purpose is to remove the impurities contained in the cotton fiber, such as cottonseed hulls, cotton wax, pectin, protein, not-removed paste in the desizing process, Dirty grease and so on. In the recent 20 years, with the promotion of high-efficiency short-flow pretreatment processes such as caustic soda-baths and cold pad mills, raising the scouring speed, saving energy, reducing water consumption and shortening the process flow have become prominent issues, Information speed, strong emulsifying power, high detergency, high temperature and concentrated alkali, resistant to hard water, low foam 沬, biodegradable, safe and non-toxic efficient rapid refining agent. To achieve the above performance and requirements, a single surfactant has been unable to meet, for some, to be synergistic and synergistic effect from the development of complex with a variety of surfactants and other inorganic and organic additives to develop a new and efficient refining Agent.
As a refining agent, in addition to the physical and chemical properties of surfactants and application performance requirements more comprehensive outside, you should also consider the price, source and other factors. The overall requirements should be superior comprehensive application functions, the cost is reasonable. Efficient sizing agents are designed to analyze single surfactants that, from a structural and performance standpoint, show good wetting, permeation, emulsification, dispersion, and cleansing surfactants in a proportion to better synergize And synergy. Auxiliary plant compound refining agent or printing and dyeing plant self-compound refining agent should follow this principle. Therefore, the refining agent is a traditional and time-keeping issue, and the development of surface science enables us to make the transition from traditional trial and error to science-based understanding.
