Polyester (polyester fiber), e 'ngoe ea likhoele tsa maiketsetso tse hlahisoang ka ho fetisisa lefatšeng, e se e le thepa ea mantlha indastering ea masela ka lebaka la litšobotsi tsa eona tse ntle tsa 'mele le tsa mochini, botsitso ba lik'hemik'hale le ts'ebetso ea eona. Litšobotsi tsa eona tsa ts'ebetso li entse hore e be boemong bo ke keng ba nkeloa sebaka lekaleng la liaparo, masela a lapeng le a indasteri.
I. Melemo ea Ts'ebetso ea Motheo
1. Matla a Phahameng le ho hanyetsa Abrasion
Matla a ho pshatla ha polyester a ka fihla ho 3.5-5.0 cN/dtex, makhetlo a mabeli ho isa ho a mararo a likhoele tsa tlhaho, 'me ho hanyetsa ha eona ke ho bobeli ho feta nylon. Sena se etsa hore e tšoanelehe bakeng sa lisebelisoa tse phahameng tse kang liaparo tsa mosebetsi, lisebelisoa tsa ka ntle le lik'hapete.
2. E babatsehang Elasticity
Polyester e na le modulus ea pele e phahameng (hoo e ka bang 90-120 cN/dtex), e bakang ho holofala ho fokolang tlasa khatello ea maikutlo le ho boloka sebopeho se setle haholo. Esita le ka mor'a ho otlolloa ka 10%, e ntse e ka khutlela sebopeho sa eona sa pele, e leng se etsang hore e sebelisoe hangata liaparong tse hlokang ho lekana hantle, tse kang lihempe le lisutu.
3. Khanyetso e ikhethang ea lik'hemik'hale
E bontša botsitso bo phahameng khahlanong le li-acids (ntle le nitric acid e ngata), alkalis (e hanyetsanang le metheo e fokolang mocheso oa kamore), le li-oxidants, 'me e bontša khanyetso e phahameng ho lihlapolli tsa tlhaho ha li bapisoa le likhoele tsa tlhaho. Thepa ena e e etsa hore e sebelisoe haholo lisebelisoa tsa ho sefa liindasteri, liaparo tse sireletsang le masimo a mang.
II. Thepa e sebetsang le likhetho tsa ho fetola
1. Thermal le Dimensional Stability
Polyester e na le mocheso oa phetoho ea khalase oa hoo e ka bang likhato tse 67-81. Ho futhumala ha nakoana ka likhato tse 150 ho fella ka ho fokotseha feela, ha ho bola ho qala ka likhato tse 240. Hygroscopicity ea eona e tlase (ho khutlisa mongobo ka 0.4%) ho etsa hore lesela le fokotsehe haholo (hangata le ka tlase ho 2%), le etsa hore le tšoanelehe bakeng sa liaparo tse hlokang ho lekana hantle.
2. Tlhokomelo e Bonolo
Sebopeho sa eona sa hydrophobic se e etsa hore e somane-e thibane 'me e be bonolo ho aene, empa ho monya mongobo le ho phefumoloha ha eona ho batla ho fokola. Liphetoho ho tse khethehileng-karolo (tse kang cruciform le pentagonal shapes) li ka ntlafatsa ho monya mongobo le ho omisa kapele-, athe theknoloji ea microporous foaming e ka matlafatsa ho boloka mocheso.
3. Katoloso ea Ts'ebetso
Phetoho ea Copolymerization e ka fana ka tšireletso ea UV, thepa e thibelang likokoana-hloko, le mahlaseli a kotsi a hole-. Mekhoa e kopaneng ea ho ohla (joalo ka polyester/spandex core-spun khoele) e kopanya ho otlolla le ho boloka sebopeho.
3. Phetoho ea Kopo
Polyester e kopana le litlhoko tse fapaneng ka ts'ebetso e fapaneng: polyester e tloaelehileng e sebelisoa ka liaparo tsa feshene tse potlakileng; -polyester e matla e sebelisoang liropong le mabanta a tšireletso; 'me ultra-fine denier polyester (filament e le 'ngoe Ka tlase ho kapa e lekanang le 1 dtex) ke khetho e ratoang bakeng sa masela a phahameng-joaloka masela a silika{4}.
Nakong e tlang, ka ntshetsopele ya{{0}poliester e thehilweng ka bioloji le thempereichara e bohlale-e laolang likhoele, thepa ena ea khale e tla tsoelapele ho etella pele boqapi ba theknoloji indastering ea masela.
