Seile lebanta ka ho fetisisa e atisa ho sebelisoa thepa maiketsetso joalokaha poliester le la nylon mekhahlelo e 'meli. Har'a bona, poliester le la nylon ba arotsoe ka mefuta e sa tšoaneng.
Poliester: Product lebitso poliester, nhua polyethylene terephthalate lebitso libuka tsa saense e se e ntse diester, khutsufalitsoe joalokaha PET. Poliester na molemo oa molemo futhumatsa ntlo manganga, deformation nyenyane, ha ho bonolo ho monya mongobo, matla phahameng. Ao ho 'ona ea poliester khoele ea ka tshebetso ya yona pele, arotsoe ka matla phahameng (khr, ba sa rutehang mofuta), e phahameng modulus tlaase shrinkage, mofuta tlaase shrinkage, le tlaase shrinkage thaepa.
Nylon: il'o hoeba lebitso la nylon, nylon 6 le la nylon 66, nylon arotsoe ka mefuta e 'meli. Nylon 6 e polycaprolactam lebitso saense, khutsufalitsoe joalokaha PA6, PA66 lebitso libuka tsa saense ke polycaprolactam adipamide, khutsufalitsoe PA66. le menyetla kakaretso oa mehleng oa nylon e ke matla ea phahameng, mokhathala ho itoanela la lintho tse nyenyane, le tlaase segokanyipalo. Empa ea drawback ke mongobo phahameng boele, qalile ho hlaseloa ke tshusumetso tikoloho.
