Question

what is the difference between nylon 66 and nylon 6

Answer 1

Both Nylon 6 and Nylon 6,6's polyamide chains are held together using hydrogen bonds, adding to the strength and dexterity of the fibers. Nylon 6's crystal structure contains parallel chains with hydrogen bonds between each chain, forming a more open structure with less internal hydrogen bonding. Compared to Nylon 6's crystal structure, Nylon 6,6 is tighter with less openings, making it the stronger and more resistant to heat of the two Nylons. Since Nylon 6,6's structure contains no set direction it makes the surface 12 percent harder and 20 percent more resilient than Nylon 6.

Answer 2

basic difference between nylon 66 and nylon 6 is that nylon 66 contain 6-6 C in each monomer unit and nylon 6 contain only one monomer I.e. caprolactom
