Water Wool Detergent

Cold water textile detergent and wool fulling agent. 

In the conventional scouring machine (Fig. 5-17), raw wool is propelled through a tank filled with warm water containing detergent, raked through the bowl, conveyed by means of a transfer mechanism to squeezing rollers and then earned into another similar tank. The bowls have false bottoms consisting of perforated plates...

Along with the fiber stracture damage, some bacteria and fungi decrease its quality by making wool dirty blue or green that may not be removed by water or detergents. Splotches of color also occur on wool, for example, due to the impact... 

Nonionic detergents are usually viscous liquids with excellent solubility in all kinds of water. They are particularly good detergents for wool and have found their widest acceptance in this branch of the textile industry.

A combination of 2 parts of caustic soda and 1 part of sodium carbonate is often used in single stage boiling. Soda-ash softens the water while interacting with Ca and Mg salts (if such are present) it creates an active reaction of the medium which is most favourable for the formation of stable emulsions and suspensions increases fibre swelling, thus contributing to the release of impurities from the fibre neutralises fatty acids contained in the fabric by soap formation obviates soap hydrolysis in the presence of wool reduces the adherence of detergents to wool in the alkaline medium conditions. 

Scouring of wool is mainly done by detergent and solvent. The main components of wool scouring waste water are wool grease, suint and dirt and excrement. Table 13.13 shows the pollutant load of the wool scouring effluent. The detergent...
