John Rex Whinfield tau sau ntawv patent rau cov khoom siv rau tsiaj nrog James Tennant Dickson thiab lawv cov neeg ua haujlwm hauv Calico Printers 'Association hauv Manchester xyoo 1941. Xyoo 1946, lub tebchaws United Kingdom tau luam tawm thawj daim npav rau kev npaj tsiaj, thiab thaum 1949 British ICI tiav tus tsav, tab sis tom qab DuPont muas tus patent, nws tsim tau cog ntau lawm hauv 1953 thiab yog thawj lub ntiaj teb ua kom muaj ntau lawm. Ntxov ntxov tsiaj yog yuav luag txhua siv nyob rau hauv hluavtaws fibers, feem ntau hu ua polyester, pes tsawg hauv Suav teb.
Txij li thaum 80's, tus tsiaj ua ib lub tshuab ua haujlwm engineering tau ua txoj kev nce qib, qhov kev tsim kom muaj tus neeg sawv cev nucleating thiab tus sawv cev ntawm crystallization, tus tsiaj ntawv thiab PBT ua ke raws li thermoplastic polyester, ua ib ntawm tsib yam loj ntawm cov khoom siv hlau. Nplai ntawm tus tsiaj cov khoom nyob rau hauv Suav lag luam lags deb qab ob peb lub lag luam loj hlob txawv teb chaws. Nkag mus rau ntawm 80's, Suav teb maj mam pib ua kaum ntawm tons ~ pua pua txhiab tus tons ntawm cov khoom siv hluav taws xob ntau dua los ntawm abroad, qhov zoo thiab cov zis tau ua tiav zoo. Raws li lub Tuam Tshoj Textile Society txheeb cais, 1997 Tuam Tshoj tus zus ntawm cov tsiaj ua liaj ua teb 1.74 plhom tons, uas yog siab ntim viscosity ntim nrog sliced resin qhuav muaj peev xwm ntawm 224.000 tons, yog li ntawm qhuav Engineering Plastics qib cob qhia tau txaus. Vim los ntawm kev npaj ntawm ntau hom kev hloov kho tsiaj yas thiab lwm hom polymer mixing modification ntaus ntawv yog universal, domestic mixing extruder thiab lwm yam kev tsim tseem tsim muaj ib qho kev ntsuas, ntev li ntev raws li qhov kev lag luam ib zaug qhib, domestic tsiaj yas ntau lawm tseem yuav loj hlob sai heev.
