Nylon 6 chip is obtainable by hydrolytic polymerization of caprolactam in the presence of dicarboxylic acids as chain regulators, subsequent processing of the polymer melt into chip, extraction of the low molecular weight portions from the chip with water and subsequent drying of the chip.
Nylon 66 is made of hexamethylene diamine and adipic acid are combine with water in a reactor which gives nylon salt after polymerization process nylon 66 is produced. They are used for manufacturing textile grade yarns as well as industrial products. Available luster are Bright & Semi Dull.
