Dab tsi yog Specifications ntawm Polyester Xov Paj?

Dab tsi yog qhov txawv ntawm polyester yarn thiab polyester yarn?
Polyethylene yarns xa mus rau yarns spun los ntawm polyester, uas yog cov fibers ua los ntawm ib chav kawm ntawm polymers los ntawm spinning. polyethylene terephthalate feem ntau yog cov fibers ua nrog ethylene glycol phthalate. Raws li lus Askiv lub npe ntawm nws cov ntaub ntawv raw, PET fibers luv luv. Nws yog feem ntau hu ua dacron nyob rau hauv peb lub teb chaws. Feem ntau lub npe hu ua "yarn", qhov tseeb, yog hais txog "yarn" thiab "xov", nyob rau hauv cov ntaub ntawv ntawm cov khoom siv science yog txhais raws li nram no: "yarn" yog ntau luv fibers los yog filament teem rau hauv ib tug kwv yees li ntawm lub xeev, thiab raws li kev sib hloov axial, tsim los ntawm qee lub zog thiab cov kab tawm ntawm cov khoom sib luag; Ib "xov" yog ib txoj hlua uas ua los ntawm ob lossis ntau dua ib lub xov paj. Cov xov paj yog paj rwb, ntaub plaub, hemp, tshuaj fibers elongated thiab spun rau hauv nyias strands (feem ntau yog siv los ua raw cov ntaub ntawv rau weaving), thiab ces paj rwb, hemp, txhob lo lo ntxhuav, ntaub plaub thiab lwm yam nyias strands ntawm nyias strands, hu ua xov.
Polyester fibers hais txog cov fibers ua los ntawm spinning ntawm ib chav kawm ntawm polymers uas muaj ester pawg ntawm lawv cov chains tseem ceeb. Lawv feem ntau xa mus rau cov fibers ua nrog ethyl phthalate ua raw khoom. Raws li lus Askiv lub npe ntawm lawv cov ntaub ntawv raw, PET fibers yog abbreviated li "terephthalate". Nws yog feem ntau hu ua dacron nyob rau hauv peb lub teb chaws. Feem ntau lub npe hu ua "yarn", qhov tseeb, yog hais txog "yarn" thiab "xov", nyob rau hauv cov ntaub ntawv ntawm cov khoom siv science yog txhais raws li nram no: "yarn" yog ntau luv fibers los yog filament teem rau hauv ib tug kwv yees li ntawm lub xeev, thiab raws li kev sib hloov axial, tsim los ntawm qee lub zog thiab cov kab tawm ntawm cov khoom sib luag; Ib "xov" yog ib txoj hlua uas ua los ntawm ob lossis ntau dua ib lub xov paj.
