Cov yam ntxwv ntawm polyester
1. Lub zog muaj zog. Qhov luv fiber ntau zog yog 2.6 ~ 5.7cN / dtex, thiab siab tenacity fiber yog 5.6 ~ 8.0cN / dtex. Vim nws tsis tshua muaj hygroscopicity, nws lub zog ntub thiab qhuav lub zog yog qhov zoo ib yam. Qhov cuam tshuam lub zog yog 4 npaug siab dua nylon thiab 20 npaug siab dua viscose fiber.
2. Zoo yoog raws. Lub elasticity yog ze rau ntawm cov ntaub plaub, thiab nws yuav luag tag nrho rov qab thaum nws stretches 5% mus rau 6%. Lub wrinkle kuj zoo dua li lwm cov fibers, uas yog, cov ntaub tsis wrinkled thiab muaj qhov zoo ntawm qhov ntev. Modulus ntawm elasticity yog 22 ~ 141cN / dtex, uas yog 2 ~ 3 zaug siab dua nylon. .Polyester npuag muaj lub zog siab thiab elastic rov qab muaj peev xwm, yog li nws yog ruaj, tiv thaiv wrinkle thiab tsis-ironing.
3. Thaum tshav kub kub-resistant polyester yog tsim los ntawm yaj spinning, thiab cov tsim fiber ntau tuaj yeem ua kom sov thiab yaj dua, uas yog cov thermoplastic fiber ntau. Cov ntsiab lus melting ntawm polyester yog qhov siab, thiab qhov tshwj xeeb kub muaj peev xwm thiab thermal conductivity yog me me, yog li qhov kub tsis kam thiab thermal rwb thaiv tsev ntawm polyester fiber ntau dua. Nws yog qhov zoo tshaj plaws ntawm cov hluavtaws fibers. 4. Polyester muaj ib tug du nto thiab nruj nreem kaw nyob rau hauv lub molecules. Polyester yog qhov zoo tshaj plaws tshav kub-resistant ntaub ntawm hluavtaws fibers. Nws yog thermoplastic thiab tuaj yeem ua rau hauv pleated tiab nrog ntev pleats. Nyob rau tib lub sijhawm, polyester fabrics muaj qhov tsis zoo melting tsis kam thiab nws yooj yim rau kev tsim qhov nyob rau hauv muaj cov hmoov tshauv thiab sparks. Yog li ntawd, sim zam kev sib cuag nrog cov luam yeeb pob tw, sparks, thiab lwm yam thaum hnav.
5. Zoo abrasion tsis kam. Kev puas tsuaj yog qhov thib ob tsuas yog nylon, uas yog qhov zoo tshaj plaws hauv kev puas tsuaj, thiab zoo dua li lwm cov fibers ntuj thiab hluavtaws fibers.
6. Lub teeb ua haujlwm zoo. Lightfastness yog thib ob tsuas yog acrylic fiber. Lub teeb ceev ceev ntawm polyester ntaub yog zoo dua, tshwj tsis yog tias nws yog qhov phem dua li acrylic fiber, nws lub teeb nrawm yog zoo dua li cov ntaub fiber ntau. Tshwj xeeb tshaj yog lub teeb nrawm tom qab iav yog qhov zoo heev, yuav luag sib npaug nrog acrylic fiber.
7. khaws cia. Nws tiv taus cov tshuaj bleaching, oxidants, hydrocarbons, ketones, roj av khoom thiab inorganic acids. Nws yog resistant rau dilute alkali, tsis ntshai ntawm mildew, tab sis kub alkali yuav ua rau nws decompose. Kuj tseem muaj zog tiv thaiv acids thiab alkalis, thiab UV tsis kam
8. Cov dyeability tsis zoo, tab sis cov xim ceev ceev yog qhov zoo, thiab xim tsis yooj yim rau ploj. Vim tias tsis muaj ib pawg dyeing tshwj xeeb ntawm cov saw molecular ntawm polyester, thiab cov polarity me me, dyeing nyuaj dua, dyeability tsis zoo, thiab cov xim molecules tsis yooj yim nkag mus rau hauv fiber ntau.
9. Tsis zoo hygroscopicity, sultry zoo thaum hnav, thiab yooj yim rau them nrog hluav taws xob zoo li qub thiab av, uas cuam tshuam rau qhov tsos thiab kev nplij siab. Txawm li cas los xij, nws yooj yim heev kom qhuav tom qab ntxuav, thiab lub zog ntub dej tsis tshua poob, tsis deform, thiab muaj kev ntxuav zoo thiab hnav zoo.
