1.Polyesterfiber ntau
Polyester fiber ntau yog polyester, belongs rau cov hloov polyester, belongs rau ntau yam kev kho mob (hloov los ntawm cov phooj ywg nco ntsoov) nws txhim kho cov dej polyester cov ntsiab lus yog tsawg, tsis zoo permeability, tsis zoo dyeing, yooj yim pilling, yooj yim rau stain thiab lwm yam shortcomings. Nws yog ua raws li refined terephthalic acid (PTA) los yog dimethyl terephthalate (DMT) thiab ethylene glycol (EG) raws li raw cov ntaub ntawv los ntawm esterification los yog transesterification thiab condensation cov tshuaj tiv thaiv los npaj cov polymer - polyethylene terephthalate (PET), spun thiab tom qab kev kho mob ua. ntawm fiber.
Qhov zoo: ci ntsa iab, nrog cov nyhuv flash, xav tias du, tiaj tus, zoo elasticity; Anti-wrinkle ironing, zoo lub teeb ua haujlwm; Tuav tus txhob lo lo ntxhuav nruj nreem ntawm tes thiab loosen yam tsis pom tseeb crease.
Qhov tsis zoo: luster tsis yog mos txaus, tsis zoo permeability, nyuaj dyeing, tsis zoo melting kuj, yooj yim rau tsim qhov nyob rau hauv lub ntsej muag ntawm soot, Mars thiab lwm yam.
Lub discovery ntawm polyester
Polyester, tsim nyob rau hauv 1942 los ntawm JR Whitfield thiab JT Dixon, tau tshwm sim los ntawm kev tshawb fawb ntawm WH Carothers, tus kws tshawb fawb Asmeskas uas tshawb pom nylon! Thaum nws siv los ua cov fiber ntau, nws tseem hu ua polyester, thiab yog tias nws siv hauv, piv txwv li, lub raj mis yas, nws hu ua PET.
Txheej Txheem: Kev tsim cov polyester fibers feem ntau suav nrog cov kauj ruam hauv qab no
(1) Polymerization: terephthalic acid thiab ethylene glycol (feem ntau ethylene glycol) yog polymerized los ua ib lub polyester polymer;
(2) Spinning: los ntawm melting lub polymer thiab dhau los ntawm spinning pore phaj los ua ib tug nruam fiber ntau;
(3) Kho thiab ncab: cov fibers tau txias thiab kho thiab ncab ntawm lub stretcher los txhim kho lub zog thiab kav ntev;
(4) Kev tsim thiab kev kho tom qab: fibers tuaj yeem tsim los ntawm ntau txoj hauv kev xws li textile, weaving, xaws, thiab tom qab kev kho mob, xws li dyeing, printing thiab xov.
Polyester yog qhov yooj yim tshaj plaws ntawm peb cov hluavtaws fibers, thiab tus nqi kuj pheej yig. Nws yog ib hom tshuaj fiber ntau khaub ncaws ntaub siv hauv lub neej txhua hnub. Nws qhov txiaj ntsig loj tshaj plaws yog tias nws muaj qhov zoo wrinkle tsis kam thiab zoo li qub, yog li nws tsim nyog rau cov khoom siv sab nraum zoov xws li cov ris tsho sab nrauv, txhua yam ntawm lub hnab thiab cov tsev pheeb suab.
Qhov zoo: siab zog, muaj zog elasticity ze rau ntaub plaub; Thaum tshav kub kub tsis kam, lub teeb tsis kam, hnav tsis kam thiab tshuaj lom neeg ua haujlwm zoo;
Disadvantages: tsis zoo staining, tsis zoo yaj kuj, tsis zoo noo noo nqus thiab yooj yim rau pilling, yooj yim rau stain.
2.Paj rwb
Nws hais txog cov ntaub uas ua los ntawm paj rwb ua raw khoom. Feem ntau, paj rwb fabrics muaj zoo dua noo noo nqus thiab tshav kub tsis kam thiab xis hnav. Qee qhov kev lag luam khaub ncaws uas yuav tsum muaj kev nqus dej siab tuaj yeem xaiv cov paj rwb ntshiab rau kev ua haujlwm. Piv txwv li, hnav khaub ncaws hauv tsev kawm ntawv lub caij ntuj sov.
Qhov zoo: paj rwb fiber ntau noo noo nqus tau zoo dua, elasticity kuj tseem siab, kub thiab alkali tsis kam, kev noj qab haus huv;
Disadvantages: yooj yim rau wrinkle, yooj yim rau shrink, yooj yim deformation, yooj yim rau lo plaub hau yog tshwj xeeb tshaj yog ntshai ntawm acid, thaum concentrated sulfuric acid stained paj rwb, paj rwb yog hlawv rau hauv qhov.
3.Nylon
nylon yog Suav lub npe ntawm hluavtaws fiber ntau nylon, lub npe txhais lus tseem hu ua "nylon", "nylon", lub npe scientific yog polyamide fiber, uas yog, polyamide fiber. Vim tias Jinzhou chemical fiber Hoobkas yog thawj cov khoom siv hluavtaws polyamide fiber ntau hauv peb lub tebchaws, nws yog lub npe hu ua "nylon". Nws yog lub ntiaj teb ua ntej tshaj plaws hluavtaws fiber ntau, vim nws cov kev ua tau zoo heev, cov khoom siv raw khoom nplua nuj, tau siv dav.
Qhov zoo: muaj zog, zoo hnav tsis kam, qeb duas ntawm tag nrho cov fibers; Lub elasticity thiab resilience ntawm nylon ntaub yog zoo heev.
Disadvantages: Nws yog ib qho yooj yim rau deform nyob rau hauv me me sab nraud quab yuam, yog li nws cov ntaub yog yooj yim rau wrinkle thaum hnav; Qhov cua tsis zoo, yooj yim los tsim hluav taws xob zoo li qub.
4.Spandex
Spandex yog ib hom polyurethane fiber ntau, vim nws cov elasticity zoo heev, nws tseem hu ua elastic fiber, uas tau siv dav hauv cov khaub ncaws fabrics thiab muaj cov yam ntxwv ntawm elasticity siab. Nws yog tsuas yog siv nyob rau hauv kev tsim cov khaub ncaws nruj, sportswear, jockstrap thiab ib leeg, thiab lwm yam. Nws muaj ntau yam raws li kev xav tau ntawm kev siv, yuav muab faib ua warp elastic ntaub, weft elastic ntaub thiab warp thiab weft ob-txoj kev elastic ntaub.
Qhov zoo: loj txuas ntxiv, zoo zoo khaws cia, thiab tsis muaj wrinkle; Qhov zoo tshaj plaws elasticity, zoo lub teeb tsis kam, acid tsis kam, alkali tsis kam, hnav tsis kam; Nws muaj cov khoom dyeing zoo thiab yuav tsum tsis txhob ploj mus.
Qhov tsis zoo: lub zog tsis zoo, tsis zoo noo noo nqus; Spandex feem ntau tsis siv ib leeg, tab sis yog sib xyaw nrog lwm cov ntaub; Tsis zoo cua sov.
