Overview

Description

Guar gum is a macromolecular natural hydrophilic colloid that can be extracted from the fruit of the carob tree and guar beans. Guar gum is connected with mannopyranose units as the backbone to form the main chain, which has a similar structure to cellulose, so it can be quickly adsorbed on the surface of fibers, and can provide a large number of hydroxyl groups for the formation of hydrogen bonds between fibers, which can effectively to promote the bonding between fibers. In addition, guar gum improves retention of fillers and fines while avoiding undesirable flocculation between fibers. Guar gum can be dissolved in cold or hot water to form a sol, and the pH of the natural solution is between 6-8. Guar gum is divided into food grade and industrial grade, and is widely used in food, medicine, petroleum, daily chemical, papermaking, textile, printing and dyeing and other industries.
