Polyester (Polyester Fiber), Ib qho ntawm lub ntiaj teb feem ntau tsim hluav taws xob, tau dhau los ua cov khoom siv hauv lub cev thiab cov kws kho mob, tshuaj lom neeg ruaj khov, thiab kev ua haujlwm. Nws cov yam ntxwv ua tau zoo tau khwv tau nws ib txoj haujlwm methplaceable hauv cov ris tsho, tsev textile, thiab cov xeem.
I. Cov txiaj ntsig zoo ua tau zoo
1. Muaj zog thiab ua phem tsis kam
Polyester lub zog muaj zog tuaj yeem ncav cuag 3.5- 5.0 CN / DTEX, ob mus rau peb zaug uas yog ob tsuas yog rau nylon. Qhov no ua rau nws haum rau kev siv kev siv ntau xws li cov haujlwm ua haujlwm, khoom siv sab nraum zoov, thiab cov ntaub pua plag.
2. Zoo elasticity
Polyester muaj lub siab pib modulus (kwv yees li 90-120 CN / DTEX), uas ua rau muaj kev ntxhov siab thiab ua tau zoo heev. Txawm tias tom qab tau ncab 10%, nws tseem tuaj yeem rov qab mus rau nws cov thawj uas xav tau hauv cov khaub ncaws zoo, xws li cov tsho thiab tsho thiab cov khaub ncaws.
3. Koj cov tshuaj tiv thaiv
Nws ua rau cov khoom ruaj khov rau cov accic acid), alkalis (resistant rau cov pa hluav taws xob) Cov cuab yeej no ua rau nws siv dav hauv cov ntaub ntawv ntim pom kev lim dej, cov khaub ncaws tiv thaiv, thiab lwm thaj teb.
Ii. Cov Khoom Muaj Peev Xwm thiab Kev Xaiv Kev Hloov
1. Thermal thiab seem ruaj khov
Polyester muaj lub khob hloov cua sov ntawm kwv yees li 67-81 degree. Cov cua cua sov luv luv ntawm 150℃cov txiaj ntsig hauv tsuas yog shrinkage, thaum lub sij hawm kev txiav txim siab pib ntawm 240 degree. Nws cov kev hygroscopicity qis (cov haujlwm noo noo rov qab los ntawm 0.4%) muab cov ntaub ntawv tsawg heev (feem ntau tsawg dua 2%), ua kom haum rau cov khaub ncaws uas xav tau qhia meej meej.
2. Yooj yim saib xyuas
Nws cov xwm hydrophobic ua rau nws wrinkle - tiv taus thiab yooj yim rau hlau, tab sis nws noo noo tsis zoo. Kev hloov kho rau cov ntoo khaub lig tshwj xeeb -} Cov khoom siv ua kom zoo nkauj thiab cov pa roj av) tuaj yeem txhim kho kom sov.
3. Kev nthuav dav ua haujlwm
Copolymerization hloov kho tau tuaj yeem tiv thaiv UV tsis kam, cov tshuaj tua kab, thiab kom deb} infrared hluav taws xob. Composite spinning txheej txheem (xws li polyester / spandex core- spun yarn) sib xyaw ua ke thiab ua kom nruj.
3. Thov yoog
Polyester ntsib ntau hom kev lag luam muaj ntau yam kev sib tw sib txawv: Cov pa polyester yog siv rau hauv Fashioning Apparel; high - Lub zog polyester yog siv nyob rau hauv hlua thiab siv tawv phom; Thiab ultra {- kev ua haujlwm zoo polyester (ib leeg xaiv rau high-} zoo li ntaub.
Yav tom ntej, nrog kev txhim kho ntawm bio - Raws cov khoom siv thev naus laus zis nyob rau hauv kev lag luam textile.
