Qhov no yog ib qho ntawm ntau yam khoom uas ua rau polyester xaiv zoo rau textiles thiab khaub ncaws. Polyester yog cov khoom siv hluavtaws ua los ntawm cov roj av, thiab nws cov fibers tiv taus cov shrinking, wrinkling thiab fading. Muaj ntau qhov laj thawj vim li cas polyester tsis ntsws, qee qhov kuv yuav piav qhia hauv kab lus no.
Ua ntej, polyester fibers yog kub-resistant. Lub melting point ntawm polyester yog nyob nruab nrab ntawm 230-250 degree, uas yog ntau dua li ib tug raug lub tshuab ntxhua khaub ncaws qhov siab tshaj plaws kub ntawm ib ncig ntawm 60 degree. Qhov no txhais tau hais tias txawm tias thaum ntxhua lossis ziab khaub ncaws polyester ntawm qhov kub thiab txias, cov fibers yuav tsis yaj lossis ntsws.
Qhov thib ob, polyester fibers yog noo noo-resistant. Tsis zoo li cov fibers ntuj xws li paj rwb lossis ntaub plaub, polyester tsis nqus dej. Hloov chaw, dej hlaws rau ntawm qhov chaw ntawm cov ntaub thiab swb tawm. Qhov no txhais tau hais tias thaum cov khaub ncaws polyester raug ntxuav, lawv tsis nqus dej ntau, thiab cov ntaub tsis cog lus raws li qhov tshwm sim.
Thib peb, polyester fibers muaj qhov coefficient ntawm kev sib txhuam. Qhov no txhais tau hais tias cov fibers tsis rub tawm ib leeg thaum ntxuav los yog ziab, uas txo cov kev sib txhuam vim qhov shrinkage. Tsis tas li ntawd, polyester fibers yog elastic heev thiab tuaj yeem ncav cuag li 5 feem pua ntawm lawv qhov ntev ntev, txhais tau hais tias txawm tias lawv shrink me ntsis, lawv tuaj yeem yooj yim rov qab lawv cov duab qub thiab loj.
Thaum kawg, feem ntau cov tsoos tsho polyester yog pre-shrunk ua ntej muag. Cov neeg tsim khoom siv cov txheej txheem hu ua "heat-setting" los kho cov ntaub cov duab thiab qhov loj me. Cov txheej txheem no suav nrog kev nthuav tawm cov ntaub rau qhov kub thiab txias, uas yuav pab kom ruaj khov ntawm cov fibers thiab tiv thaiv kom tsis txhob muaj kev sib txuas ntxiv.
Hauv kev xaus, polyester tsis ntsws. Nws cov cua kub thiab noo noo tsis kam, tsis tshua muaj coefficient ntawm kev sib txhuam, thiab elasticity ua rau nws zoo tagnrho cov ntaub rau khaub ncaws thiab textiles. Tsis tas li ntawd, cov txheej txheem ua ntej shrinking kom ntseeg tau tias cov ris tsho polyester tuav lawv qhov loj thiab zoo txawm tias tom qab ntxuav thiab ziab. Raws li tus kws tshaj lij textile, kuv pom zoo kom siv cov ntaub polyester rau lawv cov kav ntev, kev nplij siab, thiab kev saib xyuas qis.
