Sylic Textile Auxiliaries FAQ

Q What is wetting agent in dyeing?

A Another important auxiliary used in dyeing are wetting agents. Wetting agents are basically surfactants that lower the surface tension of a liquid, allowing easier spreading, and lower the interfacial tension between two liquids.
Q Is detergent a good wetting agent?

A Wetting agents consist of molecules that are attracted to water on one side and to waxes on the other. Wetting agents and washing detergents work the same way. The addition of ordinary washing detergent can improve the penetration of water in soil, but the effect does not last very long.
Q What is wetting and dispersing agent?

A Wetting agents are surface-active substances and improve the wetting of solids. Dispersing agents prevent particles flocculating by various mechanisms (electrostatic effects, steric effects). Wetting and dispersing additives unite both mechanisms of action in one product, i.E. They are both wetting and stabilizing.
Q Is a wetting agent the same as a surfactant?

A
All wetting agents are surfactants, but not all surfactants are wetting agents. Wetting agents are a class of surfactants that lower the interfacial tension of a liquid. An example is water. Water has a high interfacial tension, so a drop of water tends to “bead” on a hydrophobic surface, such as plastic.
Q What is the function of wetting agent?

A Wetting agents that lower the surface tension of a liquid, allowing easier spreading, and that lower the interfacial tension between two liquids.
