10 Questions
What is the main purpose of a wetting agent?
To reduce the surface tension of water
What is the surface tension of pure water at 20°C?
72.8 mN/m
What is the effect of wetting agents on the penetration of dyes into a substrate?
They make it easier for dyes to penetrate
What is the primary function of wetting agents in wet processing?
To help water or chemical penetrate the fiber surface
What is the function of the hydrophobic tail of a wetting agent molecule?
To repel water molecules
Wetting agents are used to increase the surface tension of water.
False
Wetting agents are molecules with a hydrophilic head and a hydrophobic tail.
True
Wetting agents are primarily used in wet processing to accelerate the drying of materials.
False
The surface tension of pure water is around 50 mN/m at 20 °C.
False
Wetting agents help water-based solutions to spread and penetrate surfaces more easily.
True
Learn about wetting agents, surfactants that reduce surface tension and interfacial tension, and their role in textile processing, including wetting the surface and facilitating penetration of water or chemicals into fibers.
