Glycerin (also known as glycerol) is colorless, odorless and tasteless. Sweet, an organic substance that appears as a clear, viscous liquid. It is miscible with water, alcohols, amines and phenols in any proportion, and the aqueous solution is neutral. Glycerin is a polyol moisturizer. The hydroxyl groups in the molecular structure can form hydrogen bonds with water molecules, which plays a good role in absorbing and locking water. Glycerin has a wide range of uses. Currently, it has more than 1,700 uses. It is used in both food and industry.
The role of glycerol in the textile printing and dyeing industry:
Glycerol is a commonly used organic solvent in the textile printing and dyeing industry, used to help dissolve some powdery dyes. Such as vat dyes/direct dyes/reactive dyes, etc., glycerol and urea have basically the same function and can partially replace each other.
Another function of glycerin is as a lubricant/moisture absorber for dye printing, which has special significance especially when using mechanical printing.
In the textile industry, glycerol is used as a lubricant during spinning and weaving because it is completely soluble in water and can be easily washed off the fibers.
Glycerin is used in the printing and dyeing industry to help with dyeing penetration and uniformity. The general dosage is 5%.
Derivatives of complex glycerol can be used as detergents, penetrants and emulsifiers.
