It is interesting that the melt spin process for this polymer had already been licensed in 1939 to IG Farbenindustrie for the production of PA 6 filaments.

PA6 is highly polar and absorbs up to 2.8% water (at 23°C, 50% RH) [41]. The reasons why fibers from PA 6 were not developed at DuPont are also discussed. values cannot be derived. In spite of being described in the metabolic routes of some Pseudomonas and Acinetobacter, its synthesis by biological route is not well-characterized, however, it can also be elaborated by hydrogenation of muconic acid, which has been obtained by glucose fermentation using modified strains of E. coli and Saccharomyces sp.

There are three specialty polyamides that bear mentioning for flexible packaging: PA6/66. C(CCCN)CCN Results are PA 66 chips. Stable. PA66 is sometimes used in high temperature applications such as boil-in-bag packaging. evaluated By continuing you agree to the use of cookies. The PA 66 fiber has good dye wash fastness and UV light fastness, and excellent performance in high-speed spinning processes but handling is stiffer with a slightly harsher feel as compared to PA 6 (Richards, 2005; Mather and Wardman, 2015).
