Dacron yog ib qho tseem ceeb ntawm cov hluavtaws muaj hluavtaws thiab yog lub npe ntawm tus nplais polyester fiber. Nws yog ntshiab terephthalic acid (PTA) thiab dimethyl terephthalate (DMT) thiab ethylene glycol (MEG) ua raw khoom, los ntawm esterification thiab ester pauv thiab polycondensation cov tshuaj fiber ntau polymer, polyethylene terephthalate (PET), spinning thiab tom qab fibers.
Hauv xyoo 1941, JR Winfield thiab JT Dixon ntawm lub tebchaws United Kingdom tau tsim cov polyester fibre hauv kev kuaj zauv ntawm terephthalic acid thiab ethylene glycol (Terylene). Nyob rau xyoo 1953, Tebchaws Meskas tau tsim lub tshuab hluav taws xob hu ua Dacron. Tom qab, polyester fiber tsim tau sai hauv lub ntiaj teb. Nyob rau hauv 1960 polyester fiber ntau dua polyamide fibre, kab thawj loj ntau hom hluavtaws fiber ntau
Tus qauv thiab kev ua haujlwm
Fiber ntau yam ntxwv
✪ Cov feem pua polyester yog 1.38;
✪ melting point ntawm 255 ~ 260 ℃, 205 ℃ thaum pib tsevneeg, kev tiv thaiv kev kub ntxhov yog 135 ℃;
✪ ya raws haum qis heev, tsuas 0.4% xwb;
✪ rhuav lub zog ntawm lub ntsiab lus yog 4.5 ~ 5.5 g / denier, luv fiber yog 3.5 ~ 5.5 g / hnub ci;
✪ kev loj hlob nyob rau ntawm so ntawm 15 mus rau 25% ntawm lub ntsiab lus, staple fiber rau 25 ~ 40%;
✪ ntaus lub zog siab lub zog muaj peev xwm ncav cuag 7 ~ 8 g / denier, elongation yog 7.5 ~ 12.5%.
Hom thiab yam ntxwv
1. Thaum pib ntawm cov nyom nyoos
Thaum pib ntawm cov nyom nyoos yog hais txog qhov ncaj cov hmoov qhuav uas tsis muaj qhov nyhav lo lo ntxhuav, nyob ntawm txoj kev sib nrawm feem ntau muab faib rau hauv cov hlua khoob (UDY), ib nrab ntawm txoj kab hlau kev taw qhia (nws), ua ntej kev xaim hlau (xiamen), siab kev cob qhia hlau (HOY).
2. Cov xov paj twv
Lub hnab looj ntsej muag yog hais txog cov fibers uas muaj mob qis tshaj plaws thaum lub sij hawm khov thiab muab faib rau hauv stretches (DY) thiab tagnrho-daim duab (FDY) raws li qib ntawm kev ncab.
3. Textured yarn
Los ntawm kev siv cov yam ntxwv ntawm cov tshav kub thiab cov yas ntawm cov hluavtaws ua hluavtaws, nyob hauv qhov kev txiav txim ntawm cov khoom siv thiab cov cua sov, qhov ncaj cov fiber ntau yuav ua rau cov txiv hmab txiv ntoo, uas yog hu ua deformed filament, los yog cov kab ua kom deformation. Raws li nyias cov ntaub ntawv raw khoom thiab cov tshuab ua, nws muab faib ua cov ntawv xov xwm (textured thread) (TY), ncab textured texture (DTY) thiab cov ntawv xov paj cua (ATY).
