Polyesteryog cov ntaub hluavtaws uas feem ntau muab los ntawm cov roj av.Cov ntaub no yog ib qho ntawm cov khoom siv nrov tshaj plaws hauv ntiaj teb, thiab nws tau siv ntau txhiab tus neeg siv khoom sib txawv thiab cov ntawv thov kev lag luam.
Chemically, polyester yog ib tug polymer feem ntau tsim los ntawm cov tebchaw nyob rau hauv lub ester functional pawg.Feem ntau cov khoom siv hluavtaws thiab qee cov nroj tsuag polyester fibers yog tsim los ntawm ethylene, uas yog cov khoom siv roj av uas tuaj yeem muab tau los ntawm lwm qhov chaw.Txawm hais tias qee cov ntaub ntawv ntawm polyester yog biodegradable, feem ntau ntawm lawv tsis yog, thiab polyester ntau lawm thiab siv ua rau muaj kuab paug thoob ntiaj teb.
Hauv qee qhov kev siv, polyester tej zaum yuav yog ib qho ntawm cov khoom siv tsoos tsho, tab sis nws muaj ntau dua rau polyester yuav tsum tau tov nrog paj rwb los yog lwm yam ntuj fiber ntau.Kev siv polyester hauv khaub ncaws txo cov nqi tsim khoom, tab sis nws kuj txo qhov kev nplij siab ntawm cov khaub ncaws.
Thaum sib xyaw nrog paj rwb, polyester txhim kho lub shrinkage, durability, thiab wrinkling profile ntawm no dav-tsim ntuj fiber ntau.Polyester ntaub yog heev resistant rau ib puag ncig tej yam kev mob, uas ua rau nws zoo tagnrho rau mus sij hawm ntev siv nyob rau hauv sab nraum zoov daim ntaub ntawv.
Cov ntaub peb tam sim no paub tias yog polyester pib nws nce mus rau nws lub luag haujlwm tseem ceeb tam sim no hauv kev lag luam niaj hnub hauv xyoo 1926 raws li Terylene, uas yog thawj zaug los ntawm WH Carothers hauv UK.Thoob plaws xyoo 1930 thiab 1940s, cov kws tshawb fawb Askiv txuas ntxiv txhim kho cov ntaub ntawv zoo dua ntawm ethylene npuag, thiab cov kev siv zog no thaum kawg tau txais kev txaus siab ntawm Asmeskas cov tub lag luam thiab cov neeg tsim khoom tshiab.
Polyester fiber ntau yog tsim los rau kev noj ntau los ntawm DuPont Corporation, uas kuj tau tsim lwm cov khoom siv hluavtaws xws li nylon.Thaum Ntiaj Teb Tsov Rog Zaum II, cov Allied powers pom lawv tus kheej xav tau fiber ntau rau parachutes thiab lwm yam khoom siv tsov rog, thiab tom qab tsov rog, DuPont thiab lwm lub tuam txhab Asmeskas tau pom cov neeg siv khoom lag luam tshiab rau lawv cov khoom siv hluavtaws hauv cov ntsiab lus ntawm kev lag luam tom qab kev lag luam.
Thaum xub thawj, cov neeg siv khoom tau zoo siab txog kev txhim kho qhov ntev ntawm polyester piv rau cov fibers ntuj, thiab cov txiaj ntsig no tseem siv tau niaj hnub no.Nyob rau hauv xyoo tsis ntev los no, txawm li cas los xij, qhov teeb meem ib puag ncig ntawm cov khoom siv hluavtaws no tau los ua kom pom tseeb, thiab cov neeg siv khoom ntawm polyester tau hloov pauv ntau.
Txawm li cas los xij, polyester tseem yog ib qho ntawm cov khoom siv dav tshaj plaws hauv ntiaj teb, thiab nws nyuaj rau nrhiav cov neeg siv khoom siv uas tsis muaj tsawg kawg yog qee feem pua ntawm polyester fiber.Cov khaub ncaws uas muaj polyester, txawm li cas los xij, yuav yaj thaum tshav kub kub, thaum feem ntau cov fibers char.Molten fibers tuaj yeem ua rau lub cev tsis zoo.
Yuav cov khoom zoo, tus nqi qispolyester txaj ntaubntawm no.
