Dab tsi yog cov yam ntxwv ntawm polyester yarn?

Taw qhia: Polyester yarn yog hais txog cov xov paj spun los ntawm polyester, uas yog fiber ntau ua los ntawm ib chav kawm ntawm polymers los ntawm spinning. Tam sim no, polyester feem ntau yog hais txog cov fibers ua nrog ethyl phthalate ua raw khoom. Raws li lus Askiv lub npe ntawm lawv cov ntaub ntawv raw, "PET" fibers yog 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" ua ke, hauv cov khoom siv hauv khaub ncaws kev tshawb fawb tau txhais raws li hauv qab no: "yarn" yog ntau luv fibers lossis filament teem rau hauv kwv yees li ntawm lub xeev, thiab raws li kev sib hloov ntawm axial xyoo, tsim los ntawm ib qho kev muaj zog thiab cov kab ncaj nraim ntawm cov khoom siv; Thiab "xov" yog ua los ntawm ob los yog ntau tshaj ib lub xov paj. Cov xov paj yog paj rwb, ntaub plaub, hemp, tshuaj fibers elongated thiab viscose 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 nyias strands, hu ua xov.
1. Lub zog muaj zog. Vim nws cov cuab yeej hygroscopic tsawg, nws lub zog ntub dej yog qhov zoo ib yam li lub zog qhuav. Kev cuam tshuam lub zog yog 4 npaug siab dua nylon, 20 npaug siab dua li viscose fiber.
2. Zoo elasticity. Lub elasticity yog ze rau ntawm cov ntaub plaub, thiab tuaj yeem rov qab yuav luag tag. Wrinkle kuj yog ntau dua li lwm cov fibers, uas yog, cov ntaub tsis wrinkle, zoo seem stability. Nws yog 2 ~ 3 zaug siab dua li nylon. Polyester npuag muaj lub zog siab thiab ua haujlwm zoo, yog li nws ceev ceev, ruaj khov thiab tsis muaj ironing.
3. Thaum tshav kub kub resistant polyester yog tsim los ntawm melting spinning, tsim fiber ntau tuaj yeem ua kom sov thiab yaj dua, yog cov thermoplastic fiber. Cov ntsiab lus melting ntawm polyester yog qhov siab, thiab qhov tshwj xeeb tshav kub muaj peev xwm thiab thermal conductivity tsawg dua, yog li qhov kub thiab txias rwb thaiv tsev ntawm polyester fiber ntau dua. Nws yog qhov zoo tshaj plaws hauv cov hluavtaws fibers.
4. Zoo thermoplasticity, tsis zoo fusible kuj. Vim hais tias ntawm nws qhov chaw du thiab nruj molecular kev npaj nyob rau hauv, polyester yog ib tug ntaub nrog zoo kub kuj nyob rau hauv hluavtaws fiber ntaub, thermoplastic, yuav ua tau rau hauv pleated tiab, thiab pleated. Nyob rau tib lub sijhawm, polyester ntaub muaj qhov tsis zoo melting tsis kam, thiab nws yog ib qho yooj yim los tsim lub qhov thaum nws ntsib soot thiab sparks. Yog li ntawd, hnav yuav tsum sim zam kev sib cuag nrog cov luam yeeb pob tw, sparks thiab lwm yam.
