ʻO Nylon a i ʻole Polyamide kahi ʻohana nui loa, ʻo Polyamide 6.6 a me 6 i hoʻohana nui ʻia i ka ʻenehana ʻoihana. Ma ka ʻōlelo kemika, ʻo Polyamide 6 hoʻokahi monomer me 6 mau kalapona kalapona. Hana ʻia ka Polyamide 6.6 mai 2 monomers me 6 carbon atoms i kēlā me kēia, e hopena i ka koho ʻana o 6.6.
