Polyamide yog cov ntaub ua los ntawm cov fibers ntawm cov khoom siv hluavtaws tau los ntawm kev sib cuam tshuam ntawm ntau yam kev daws teeb meem thiab polyamide alloys. Feem ntau, aliphatic polyamides yog siv kom tau cov khoom zoo li no.
Kev tsim khoom ntawm ntau yam polyamide-raws li ntaub tau tsim rov qab rau xyoo 60s ntawm lub xyoo pua xeem. Twb tau nyob rau hauv cov xyoo ntawd, fabrics tau saturated nrog ntau yam aromas thiab muab lawv ib tug heev kub kuj.
Niaj hnub no, cov khoom tsim los ntawm cov ntaub no nrov heev thoob plaws lub ntiaj teb, vim nws cov khoom pab cov khaub ncaws kom zoo nkauj rau lub sijhawm ntev. Ntawm tag nrho cov zoo, ib tug yuav tshwj xeeb tshaj yog hais txog zoo breathability. Polyamide yog cov ntaub feem ntau siv rau cov khaub ncaws ncaws pob vim nws muaj zog, hnav thiab mos.
Yuav kom polyamide ntaub kom tau raws li tej yam yuav tsum tau, nws yog tsim los siv ib tug tshwj xeeb tsim technology, uas muaj xws li peb theem:
- Kev tsim cov fibers lawv tus kheej.
- YPolymer synthesis.
- Texile processing.
YPolyamide - ntaub khoom
Ntawm cov yam ntxwv tshwj xeeb ntawm cov ntaub polymer tuaj yeem raug sau ua lub zog tensile siab lossis lwm yam kev cuam tshuam, nrog rau hnav tsis kam. Polyamide yog ib daim ntaub uas tiv taus ntau yam tshuaj los yog biochemical reagents. Nws tsis poob nws cov khoom thaum raug kub los ntawm 80 mus rau 150 degrees, uas txawv nws heev ntawm lwm yam ntaub. Ntau yam stabilizers uas siv rau hauv kev tsim cov polyamide fibers ua cov lav zoo ntawm cov khoom tsim. Txhua qhov fiber ntau no muaj kev nkag siab zoo rau cov hluav taws xob cuam tshuam (piv txwv li, zoo li qub). Yog li ntawd, polyamide yog cov ntaub uas poob nws qhov tsis kam rau thermal thiab oxidative teebmeem, nrog rau lub teeb hluav taws xob (ultraviolet radiation). Txhawm rau kho cov kev tsis txaus no, cov stabilizers tshwj xeeb tau qhia rau hauv cov khoom siv.
Polyamide npuag yog qhov xav tau zoo hauv kev tsim khoom rau
siv dav, xws li: cov khoom siv roj hmab, hlua, nuv ntses tackle, lim cov ntaub ntawv thiab lwm yam. Textured threads, uas yog ib feem ntawm polyamide ntaub nyob rau hauv lawv lub hauv paus chiv keeb, kuj nyob rau hauv kev thov heev.
Tam sim no cov xov polyamide yog tsim nyob rau hauv daim ntawv ntawm nruam spools los yog staple fibers, uas yog hu ua txawv nyob rau hauv txawv teb chaws.
Tau kawg, qee cov kev cai lij choj yuav tsum tau ua tib zoo saib thaum lub sijhawm ua haujlwm kom cov ntaub ntawv polyamide tsispoob nws qhov zoo. Piv txwv li, nws tuaj yeem ntxuav hauv lub tshuab tsis siv neeg, tab sis saib xyuas qhov kub siab tshaj plaws ntawm 40 degrees Celsius. Cov kiv cua thiab hom qhuav hauv cov khoom siv tshwj xeeb yuav tsum zam. Tom qab ntxuav, cov ntaub polyamide yuav qhuav nws tus kheej hauv lub sijhawm luv luv, uas yog cov khoom zoo ntawm cov khoom. Cov khoom nrog ntxiv polyamide fibers yuav tsum tau ironed ntawm qhov kub qis tshaj plaws thiab tsis muaj chav.
