Polyester npuag cov yam ntxwv thiab qhov zoo
Qhov zoo ntawm cov ntaub polyester:
Ua ntej, cov ntaub npuag polyester muaj lub zog siab. Cov luv luv fiber ntau lub zog yog 2.6-5.7 cN / dtex, thiab cov khoom siv high-lub zog yog 5.6-8.0 cN / dtex. Vim tias nws qhov tsawg hygroscopicity, nws lub zog ntub yuav luag tib yam li lub zog qhuav, thiab qhov cuam tshuam lub zog yog 4 npaug siab tshaj qhov ntawm nylon. Viscose fiber yog 20 npaug ntau dua.
Thib ob, lub elasticity ntawm polyester ntaub yog super muaj zog. Lub elasticity yog ze rau cov ntaub plaub. Thaum lub elongation yog 5% rau 6%, nws muaj peev xwm yuav luag zoo tu qab. Cov ntaub npuag polyester yog rov ua dua qub dua, thiab tus qauv qub tuaj yeem rov qab tau sai dua uas tsis tas tawm txoj kev qhwv. Cov qauv modulus yog 22 txog 141 cN / dtex. Nylon yog 2 mus rau 3 zaug ntau dua, uas yog tsis suav nrog los ntawm lwm cov ntaub.
Thib peb, tshav kub tsis kam ntawm polyester ntaub yog qhov zoo heev. Nws tuaj yeem hais tias polyester muaj qhov kub zoo tshaj plaws hauv cov tshuaj fiber ntau cov ntaub thiab yog cov yas tsis tshua muaj. Yog hais tias nws tau ua rau hauv daim tiab pleated, nws tuaj yeem tswj lub cev pleats zoo thiab tsis tas yuav siv ironing ntau dhau.
Plaub, cov ntaub npuag polyester muaj lub teeb zoo tiv. Cov khoom ua los ntawm polyester ntaub yog feem ntau siv tau ntev dua li ntawm cov ntaub ntawm ntuj. Muaj yeej tsis muaj teeb meem hauv kev ua kom pom cov ntaub polyester rau hnub ci. Tsis tas yuav txhawj xeeb txog kev phiv tshuaj. Cov yam ntxwv no ua rau cov ntaub xov polyester' s lub teeb tsis kam yuav luag zoo tib yam li cov ntaub acrylic.
Thib tsib, polyester ntaub tau zoo hnav tsis kam. Hnav tsis kam yog qhov thib ob tsuas yog nylon nrog qhov zoo tshaj qhov ua kom zoo dua, zoo dua li lwm yam ntuj tsim thiab hluavtaws.
Thib rau, polyester ntaub muaj cov khoom siv tshuaj zoo. Cov ntaub ua los ntawm cov ntaub polyester muaj kev puas tsuaj me me rau cov kua qaub thiab alkalis, yog li qee cov tshuaj ua kom dawb thiab oxidizing tsis ua hauj lwm txhua lub sijhawm, thiab polyester textiles tsis ntshai pwm thiab tsis ntshai kab.
Polyester nta:
1. Lub zog siab. Cov luv luv fiber ntau zog yog 2.6 txog 5.7 cN / dtex, thiab lub zog fiber ntau yog 5.6 txog 8.0 cN / dtex. Vim nws qis hygroscopicity, nws lub zog ntub yog qhov tseem ceeb tib yam li lub zog qhuav. Qhov cuam tshuam lub zog yog 4 npaug siab dua li ntawm nylon thiab 20 zaug siab dua viscose.
2. Zoo elasticity. Lub elasticity yog ze rau ntawm cov ntaub plaub, thiab thaum nws ncav los ntawm 5% rau 6%, nws tuaj yeem rov qab yuav luag zoo. Tus tiv taus wrinkle yog zoo dua rau lwm lub fibers, uas yog, cov ntaub tsis yog wrinkled, thiab qhov ntev seem yog qhov zoo. Modulus ntawm elasticity yog 22 txog 141 cN / dtex, uas yog 2 mus rau 3 zaug ntau dua qhov ntawm nylon. Cov ntaub npuag polyester muaj qhov ua kom muaj zog thiab rov qab ywj, yog li nws yog ruaj, tsis txhuam thiab tsis-hlau.
3. Thaum tshav kub kub-resistant polyester yog tsim los ntawm yaj yaj kiv, thiab cov hluav taws xob uas tsim tau tuaj yeem txuas ntxiv ua kom sov thiab yaj, uas yog cov fiber ntau thermoplastic. Polyester muaj qhov chaw siab dua thiab qhov muaj peev xwm ua hluav taws xob tsawg dua thiab cov thermal conductivity, yog li cov cua sov tsis kam thiab kub rwb thaiv tsev ntawm cov hluav taws xob polyester fiber ntau dua. Nws yog qhov zoo tshaj plaws ntawm cov khoom cua.
4. Kev ntsuas zoo thermoplasticity thiab tsis zoo tiv taus melting. Polyester yog cov cua kub tshaj plaws nyob rau hauv cov xov hluavtaws vim nws qhov chaw du thiab sab hauv cov molecules. Nws yog thermoplastic thiab tuaj yeem ua rau tiab pleats nrog pleats ntev. Nyob rau tib lub sijhawm, cov ntaub npuag polyester muaj qhov tsis zoo tiv taus kev yaj, thiab nws yog qhov yooj yim los ua qhov nyob rau hauv rooj plaub ntawm soot lossis Mars. Yog li ntawd, kev hnav yuav tsum zam kom txhob sib cuag nrog luam yeeb butts, thiab lwm yam.
5. Zoo hnav tsis kam. Hnav tsis kam yog qhov thib ob tsuas yog nylon nrog qhov zoo tshaj qhov ua kom zoo dua, zoo dua li lwm yam ntuj tsim thiab hluavtaws.
6. Lub teeb tsis kam yog qhov zoo. Lub teeb ci yog qhov thib ob rau acrylic. Cov ntaub npuag polyester muaj qhov pom kev zoo dua, thiab lawv lub teeb pom kev zoo dua li cov ntaub ntuj paj tshwj tsis yog rau cov xov acrylic. Tshwj xeeb tshaj yog nyob rau sab nraum qab ntawm lub khob, lub teeb nrawm yog qhov zoo heev, yuav luag zoo tib yam li cov acrylic fiber.
7. Kev txhim kho xeb. Nws tiv taus cov tshuaj pleev, oxidants, hydrocarbons, ketones, roj av khoom lag luam thiab cov kua qaub inorganic. Ruaj rau dilute alkali, tsis ntshai ntawm mildew, tab sis kub alkali tuaj yeem decompose nws. Kuj tseem muaj cov tshuaj tiv thaiv acid thiab alkali, UV tsis kam.
8. Dyeing yog qhov tsis zoo, tab sis cov xim nrawm yog qhov zoo thiab nws tsis yooj yim los thim. Vim tias tsis muaj ib qho tshwj xeeb dyeing pawg ntawm cov xov paj polyester molecular, thiab qhov polarity yog me me, qhov zas xim tsis yooj yim, lub zas xim tsis zoo, thiab cov zas xim tsis yooj yim nkag mus rau hauv fiber. Tsis zoo hygroscopicity, hnav ua rau lub siab xav, thiab yooj yim los nqa cov hluav taws xob zoo li qub, ua paug plua plav, cuam tshuam rau cov tsos thiab xis nyob. Txawm li cas los xij, nws yooj yim heev kom qhuav tom qab ntxuav, thiab lub zog ntub tsis muaj zog, nws tsis yog qhov deformed, thiab nws muaj kev ntxuav zoo thiab wearability. Qhov loj tshaj plaws ntawm polyester ntaub yog tias lawv tsis yooj yim deformed thiab txhuam.
