Muaj ntau txoj hlua xaws hauv khw.Ntawm lawv, polyester sewing thead thiab nyon fiaments yog ob hom kev xaws thead Koj puas paub qhov txawv ntawm lawv?Tom ntej no peb yuav qhia koj txog qhov sib txawv ntawm polyester yarn thiab nylon yarn.
Hais txog polyester
Polyester yog ib qho tseem ceeb ntawm cov hluavtaws fiber ntau thiab yog lub npe lag luam ntawm polyester fiber hauv Suav teb.Fiber-forming polymer ua los ntawm esterification los yog transesterification thiab polycondensation ntawm PTA los yog DMT thiab MEG-Polyethylene terephthalate (PET).Nws yog fiber ntau ua los ntawm spinning thiab tom qab kho.
Hais txog nylon
Nylon tau tsim los ntawm Carothers, tus kws tshawb fawb Asmeskas, thiab pab pawg tshawb fawb coj los ntawm nws.Nws yog thawj cov hluavtaws fiber ntau hauv ntiaj teb.Nylon yog ib hom polyamide fiber ntau.Cov tsos ntawm nylon tau revolutionized textiles khoom.Nws cov synthesis yog ib qho tseem ceeb hauv kev lag luam hluavtaws fiber ntau thiab yog lub hauv paus tseem ceeb hauv kev ua haujlwm siab polymer.
Qhov sib txawv ntawm Kev Ua Haujlwm
Nylon kev ua haujlwm
Muaj zog, hnav-tiv taus, ranking thawj ntawm tag nrho cov fibers.Nws hnav-tiv taus yog 10 npaug ntawm cov paj rwb fiber ntau thiab qhuav viscose fiber, thiab 140 npaug ntawm cov ntaub ntub dej.Yog li ntawd, nws durability yog zoo heev.Lub elastic thiab elastic rov qab ntawm lubnylon ntaub yogzoo heev, tab sis nws yog yooj yim deformed los ntawm sab nraud quab yuam, yog li cov ntaub yog yooj yim wrinkled thaum lub sij hawm hnav txheej txheem.Nws yog qhov tsis zoo hauv qhov cua thiab yooj yim los tsim hluav taws xob zoo li qub.
Polyester Performance
Siab zog
Lub zog luv fiber ntau yog 2.6 txog 5.7 cN / dtex, thiab lub zog siab fiber ntau yog 5.6 txog 8.0 cN / dtex.Vim nws tsis tshua muaj hygroscopicity, nws lub zog ntub yog qhov tseem ceeb tib yam li lub zog qhuav.Lub zog cuam tshuam yog 4 npaug siab dua li ntawm nylon thiab 20 npaug siab dua li viscose.
Zoo elasticity
Lub elasticity yog ze rau ntawm cov ntaub plaub, thaum nws ncav cuag 5% mus rau 6%, nws tuaj yeem yuav luag tag nrho.Lub wrinkle kuj yog superior rau lwm cov fibers, uas yog, cov ntaub yog tsis wrinkled, thiab qhov seem stability yog zoo.Lub modulus ntawm elasticity yog 22 txog 141 cN / dtex, uas yog 2 mus rau 3 zaug siab dua li ntawm nylon.
Kev nqus dej zoo
Zoo sib tsoo kuj.Hnav tsis kam ntawm polyester yog thib ob tsuas yog nylon.Nws yog zoo dua li lwm yam ntuj thiab hluavtaws fibers, thiab nws lub teeb tsis kam yog thib ob rau acrylic fiber.
Qhov sib txawv ntawm daim ntawv thov ntawm polyester thiab nylon
Xav txog qhov hygroscopicity, nyion fabricis ntau yam zoo hauv cov ntaub hluavtaws, yog li gaments ua los ntawm nylon yog ntau comiortable hnav dua polyester gaments.Nws muaj cov hnoos qeev zoo thiab corosion tsis kam, tab sis qhov kub thiab txias tsis zoo txaus.Lub roning kub yuav tsum contolled hauv qab 140 ℃ C.Ua zoo rau cov xwm txheej ntawm kev ntxuav thiab tu, thiaj li tsis ua rau cov ntaub puas. ib lub teeb fab, uas tsuas yog ited afe polypropylene thiab acrylic fabrics nyob rau hauv hluavtaws fabrics.Yog li ntawd, nws yog tsim rau mountaineering ntaub thiab lub caij ntuj no daim ntaub.
Polyester npuag tsis zoo hygroscopicity thiab sultry thaum hnav.Nws yog ib qho yooj yim los nqa cov hluav taws xob zoo li qub thiab stain plua plav, uas cuam tshuam rau cov tsos thiab kev nplij siab.Txawm li cas los xij, nws yooj yim heev kom qhuav tom qab ntxuav, thiab tsis deformed.Polyester yog qhov zoo tshaj plaws tshav kub-resistant ntaub nyob rau hauv hluavtaws fabrics.Lub melting point yog 260 ° C thiab ironing kub yog 180 ° C. Nws muaj ib tug thermoplastic perfomance thiab yuav ua tau rau hauv ib tug pleated tiab nrog ntev pleats.
Cov ntaub polyester muaj qhov tsis zoo melting tsis kam, thiab nws yog ib qho yooj yim los tsim qhov nyob rau hauv cov ntaub ntawv ntawm soot los yog mars.Yog li ntawd, hnav cov ntaub polyester yuav tsum tsis txhob sib cuag nrog cov luam yeeb butts, sparks, thiab lwm yam. Polyester fabrics muaj zoo wrinkle kuj thiab zoo zoo tuav, yog li lawv yog haum rau outerwear.
