Glycerol (also known as glycerol) is an organic substance. It is colorless, odorless and sweet. Its appearance is a clear and viscous liquid. It is miscible with any proportion of water, alcohol, amine and phenol, and the aqueous solution is neutral. Glycerol is a polyol moisturizer. Hydroxyl groups form hydrogen bonds with water molecules in the molecular structure and play a good role in water absorption and water locking. Glycerol has a wide range of uses. At present, there are more than 1700 uses for food and industry.

Role of glycerol in textile printing and dyeing industry:

In the textile printing and dyeing industry, glycerol is a commonly used organic solvent to help dissolve some powdered dyes, such as vat dyes / direct dyes / reactive dyes. Its function is basically the same as that of urea and can be partially replaced.

In addition, glycerol has another function, that is, dye printing lubricant / hygroscopic agent, especially the special significance of mechanical printing.

When glycerol is used in spinning and weaving, it is used as a lubricant in the textile industry because it can be completely dissolved in water and can be easily washed off on the fiber.

The application of glycerin in the printing and dyeing industry is conducive to dye penetration and uniformity. The general dosage is 5%.

Synthetic glycerol derivatives can be used as detergents, penetrants and emulsifiers.
