Softener is a kind of chemical substance that can change the static and dynamic friction coefficient of fiber. When the coefficient of static friction is changed, it feels smooth and easy to move on the fiber or fabric; When the coefficient of dynamic friction is changed, the fine structure between

I. Levelling agent for high temperature dyeingIn the process of high temperature and high pressure dyeing with disperse dyes, the uneven dyeing is often caused by the poor dispersibility, evenness, transference and improper control of temperature rise rate. In particular, the linear density of fine

The smaller the surface tension of the lubricant, the better its spreading performance. Under normal circumstances, the surface tension of pure water is high, up to 72.75×10-5N/cm, so it is necessary to reduce its surface tension in order to be suitable for wetting printing plates. At present, the b

Penetrants are known to play a role in osmosis, a substance that can be arranged in a directional manner on the surface of a solution to reduce surface tension. Simply put, it is a chemical that can help the substance that needs to be penetrated to penetrate into the substance that is penetrated, m

The broad concept of penetrant refers to a class of chemicals that can help the substance that needs to be permeated to penetrate the substance that needs to be permeated, and the industry generally uses surfactants (which can be anionic or non-ionic) or organic or inorganic solvents. Penetrants are

Polyethylene glycol peg, polypropylene glycol ppg, Span, Tween and so on are widely used non-ionic surfactants, usually used in makeup, food, textile and other industries more!Polyethylene glycol is used for molar molecular weight reasons, small and large arrangements can reach more than 20000, comm

In the middle of the 20th century, with the rapid development of industrial production and the rapid promotion and application of polymer materials, on the one hand, some high resistivity polymer materials such as plastic, rubber and other products are widely used and the high-speed modern productio

Nonionic surfactants have many uses. The drilling fluid used in drilling needs to add defoamer, emulsifier, fungicide, viscosifier, diluent dispersant, dewatering agent, lubricant, anti-corrosion agent, etc., which are closely related to non-ionic surfactants.Non-ionic surfactants are used in oil di

Chemical composition: Polyethylene glycol 400 monostearateType: Non-ionicAppearance: yellowish to milky white solidHLB value: 11Content: >99%Second, performance and use1, soluble with oil and organic solvents, compatible with most surfactants, stable in a wide PH range, with excellent emulsification

1. Causes of surfactant foam formationWhen a surfactant is mixed with water, the hydrophilic end dissolves in the water, and the hydrophobic end detaches from the water and gathers at the surface. In surface surfactants, hydrophobic groups will leave the water surface and enter the air, and hydrophi
