Calcium chloride is often used as a coagulant in the production of biofabrics made from natural polymers like alginate. When we dissolved it in water and then brought it into contact with the liquid based solution, a chemical reaction called cross-linking took place. This reaction resulted in the formation of a gel-like network on top of the liquid solution, which provided structural stability and strength to the material. The gelation process helped the biofabrics maintain their shape and structure during production.
