Polyamide (PA) hangata e tsejoa e le nylon, 'me nylon e telele ea k'habone e bua ka mefuta ea nylon e nang le lihlopha tse 10 kapa ho feta tsa methylene lipakeng tsa li-amide tse haufi le ketane e kholo ea macromolecule, joalo ka PA11, PA12, PA1010, PA1212, PA1012, joalo-joalo. .

Har'a bona, PA610 le PA612 li-aliphatic polyamides tse peli, khetho ea li-diamine tse telele le hexamethylene diamine condensation, ha e le hantle, ha e kopane le tlhaloso e ka holimo, ka lebaka la bolelele ba diacid ho feta 10 carbon, bolelele ba eona nako le nako ka nako. ea halofo ke ho kopana le tlhaloso ea nako e telele k'habone ketane nylon, ha bolelele ba diamine feela 6 k'habone, ho fella ka thepa ho hanyetsa mocheso le thepa mechine le thepa e meng molemo ho feta nako e telele k'habone ketane nylon, hanyenyane ka tlaase ho feta Sepheo kakaretso nylons PA6 le PA66, kahoo PA610 le PA612 hangata li khetholloa e le li-nylon tse telele tsa k'habone.

PA6 le PA66 li na le sekhahla se phahameng sa ho monya metsi, se bakang phapang e phahameng ea boholo ba sehlahisoa le thepa le mocheso o phahameng oa ts'ebetso.Li-nylon tse telele tsa carbon chain li ka etsa hore ho be le khaello ea liketane tse khutšoanyane tsa carbon ka lebaka la likarolo tse telele tsa ketane ea methylene pakeng tsa lihlopha tse haufi tsa amide.Ntle le lisebelisoa tsa mantlha tsa polyamides, li boetse li na le letsoalo le tlase le lekanyelitsoeng, ho monya metsi a tlase, botsitso bo botle ba sebopeho, khanyetso e ntle ea lik'hemik'hale, thepa e ntle ea motlakase, ho hanyetsa kutu, ho hanyetsa abrasion, ho tiea, ho hanyetsa mokhathala le ho hanyetsa mocheso o tlase.
