Qhov sib txawv tseem ceeb ntawm dacron thiab polyester yog Dacron yog ib daim ntawv ntawm polyester, thaum polyester yog cov khoom siv polymer uas muaj cov ester pawg txuas nrog cov saw tseem ceeb.
Dacron yog lub npe lag luam, thiab nws yog cov khoom siv polymer uas peb tuaj yeem nrhiav tau raws li tus tswv cuab ntawm tsev neeg polyester. Polyester yog cov khoom siv polymer uas tsim los ntawm cov tshuaj tiv thaiv ntawm carboxylic acids thiab cawv. Nyob ntawm cov khoom, cov ntaub ntawv sib txawv ntawm polyester muaj ntau daim ntawv thov.
Dacron yog dab tsi?
Dacron yog lub npe lag luam ntawm polyethylene terephthalate hauv Asmeskas. Qee lub sij hawm, peb sau ua PET lossis PETE. Nws yog cov tswv cuab feem ntau ntawm cov thermoplastic polymers ntawm polyesters. Tsis tas li ntawd, cov khoom siv polymer no muaj txiaj ntsig zoo hauv kev tsim cov fibers rau khaub ncaws, ntim khoom noj thiab dej haus, tsim cov resins, thiab lwm yam. Dacron polymer cov khoom muaj cov khoom ntawm ethylene terephthalate monomers txuas rau ib leeg ntawm polymerization. Chav tsev rov ua dua yog C10H8O4 Ntxiv mus, peb tuaj yeem rov ua cov khoom no yooj yim.

Feem ntau, peb tuaj yeem categorize dacron ua cov khoom siv semicrystalline. Tab sis, nws tuaj yeem tshwm sim hauv lub xeev amorphous thiab. Yog li ntawd, nws tuaj yeem muaj nyob hauv ob lub xeev opaque thiab pob tshab. Lawm, nws yog cov khoom tsis muaj xim thiab nws tuaj yeem nruj lossis semi-rigid nyob ntawm txoj kev tsim khoom. Txawm li cas los xij, nws yog qhov hnyav heev. Tsis tas li ntawd, cov khoom no ua rau muaj kev cuam tshuam zoo rau cov dej noo thiab cov kuab tshuaj. Tsis tas li ntawd, qhov paub zoo tshaj plaws ntawm dacron yog nws cov viscosity intrinsic.
YPolyester yog dab tsi?
Polyester yog ib lub npe siv los piav txog cov hlua ntev ntev uas muaj cov ester pawg hauv cov saw tseem ceeb. Polyesters yog chemically tsim los ntawm tsawg kawg yog 85% los ntawm qhov hnyav ntawm ester thiab dihydric cawv thiab terephthalic acid. Hauv lwm lo lus, cov tshuaj tiv thaiv ntawm carboxylic acids thiab cawv uas tsim esters ua rau tsim cov polyester.
Polyesters yog tsim los ntawm condensation cov tshuaj tiv thaiv ntawm dicarboxylic acids thiab cawv (diols). Polyesters feem ntau yog ob hom li saturated polyesters thiab unsaturated polyesters. Saturated polyesters yog tsim los ntawm cov pob txha saturated. Txij li thaum lawv saturated, cov polyesters no tsawg dua los yog tsis reactive. Unsaturated polyesters yog tsim los ntawm vinyl unsaturation. Yog li ntawd, cov ntaub ntawv polyester no reactive heev.

Polyester fibers yog qhov muaj zog thiab ruaj khov. Ntawd yog, vim tias polyesters feem ntau tiv taus cov tshuaj, ncab, shrinking, thiab lwm yam. Cov kev siv feem ntau ntawm polyester yog nyob rau hauv kev lag luam textile, kev lag luam khoom noj (rau cov ntim khoom noj), thiab lwm yam.
Qhov txawv ntawm Dacron thiab Polyester yog dab tsi?
Dacron yog lub npe lag luam thiab nws yog cov khoom siv polymer uas peb tuaj yeem nrhiav tau raws li tus tswv cuab ntawm tsev neeg polyester. Yog li ntawd, qhov sib txawv tseem ceeb ntawm dacron thiab polyester yog Dacron yog ib daim ntawv ntawm polyester, thaum polyester yog cov khoom siv polymer uas muaj cov ester pawg txuas nrog cov saw tseem ceeb. Dacron yog lub npe lag luam ntawm polyethylene terephthalate hauv Asmeskas. Nws yog ib qho tseem ceeb heev hauv kev tsim cov fibers rau khaub ncaws, ntim rau kev khaws cov khoom noj thiab dej haus, kev tsim cov resins, thiab lwm yam. Cov kev siv feem ntau ntawm polyester yog nyob rau hauv kev lag luam textile, kev lag luam khoom noj khoom haus (rau cov ntim khoom noj), thiab lwm yam.

Summary – Dacron vs Polyester
Hauv cov ntsiab lus, dacron yog lub npe lag luam thiab nws yog cov khoom siv polymer uas peb tuaj yeem nrhiav tau los ua tus tswv cuab ntawm tsev neeg polyester. Yog li ntawd, qhov sib txawv tseem ceeb ntawm dacron thiab polyester yog Dacron yog ib daim ntawv ntawm polyester, whereas polyester yog ib tug polymer cov ntaub ntawv uas muaj li ntawm ester pawg txuas mus rau lub ntsiab saw.
