Lub npe tag nrho ntawmtawv microfiberyog "PU tawv microfiber uas muaj zog dua", uas yog coated nrog PU txheej raws li microfiber hauv paus ntaub. Nws muaj kev tiv thaiv zoo heev hnav, zoo heev txias tsis kam, huab cua permeability, laus tsis kam. Txij li xyoo 2000, ntau lub tuam txhab hauv tsev kuj tau nqis peev rau hauv kev tshawb fawb thiab kev txhim kho thiab kev tsim khoom ntawm microfibers. Txawm li cas los xij, tus kws tsim khoom txoj kev tshawb fawb tob tob pom tias cov tawv microfiber uas twb muaj lawm tsuas yog coated nrog polyurethane ntawm qhov chaw ntawm lub substrate, txawm hais tias qhov hnav tsis kam ntawm cov tawv tau zoo dua, tab sis tag nrho cov kev ua tau zoo ntawm cov tawv tau cuam tshuam vim yog qhov muaj peev xwm khi tsawg ntawm polyurethane txheej thiab lub substrate.
Txawm li cas los xij, qhov tshwm sim ntawmcov microfibers uas ua los ntawm cov khoom siv bio-baseddaws qhov teeb meem no tau zoo. Hauv cov txheej txheem npaj tshwj xeeb ntawm cov microfiber bio-based, cov txheej txheem txhawb nqa thiab cov txheej txheem biological yog kho thiab xaws ua ke. Hauv txheej polyurethane, cov thev naus laus zis ultrasonic thiab ultrasonic, sab txuas cov txheej polyurethane txheej nkag mus rau qhov taper thiab qhov, txhawb kev sib txuas ntawm sab saud thiab hauv qab ntawm cov txheej polyurethane, yog li ua rau cov txheej polyurethane nce thiab nqis los ntawm qhov txuas tsim cov organic tag nrho, daws tau cov thev naus laus zis uas twb muaj lawm ntawm cov txheej nplaum polyurethane thiab cov ntaub hauv paus tsis muaj zog txaus, Tom qab ntawd nws tuaj yeem daws qhov teeb meem tev ntawm cov txheej polyurethane. Ntawm ib sab tes, nws tuaj yeem txhawb nqa lub zog tag nrho ntawm cov ntaub hauv paus thiab xyuas kom meej tias tag nrho cov tawv nqaij ruaj khov. Ntawm qhov tod tes, cov txheej txheem biological siv cov fiber chitosan, uas tuaj yeem ua lub luag haujlwm thaiv rau cov tshuaj radioactive, thiab yog qhov zoo rau kev npaj cov khoom tiv thaiv kev ua haujlwm rau cov neeg ua haujlwm koom nrog kev lag luam nuclear. Cov fiber bio elastic yog siv los txhim kho qhov elasticity tag nrho ntawm cov ntaub hauv paus, thiab kev sib xyaw ua ke ntawm Arlene fiber los xyuas kom meej tias tag nrho elasticity thiab lub zog ntawm cov ntaub hauv paus, txhim kho kev ua tau zoo tag nrho ntawm cov tawv nqaij.
Kev loj hlob ntawm cov microfibers bio-based
Ua ntej, bio-based microfiber muaj kev tiv thaiv hydrolysis zoo, hws tsis kam, laus tsis kam, hnav tsis kam thiab muaj zog tiv thaiv dej, tiv thaiv kev ua qias tuaj, tawv yooj yim los tswj thiab tsis muaj tshuaj lom rau ib puag ncig.
Qhov thib ob, cov khoom siv microfiber bio-based los ntawm kev sib xyaw ua ke ntawm biology ntawm theem hauv paus thiab txheej txhawb zog, los txhawb lub zog tag nrho thiab elasticity ntawm cov ntaub puag thiab lwm yam kev ua tau zoo, ua kom zoo lav qhov ruaj khov thiab lub neej ua haujlwm ntawm cov khoom siv tawv, thiab los ntawm cov nyhuv tiv thaiv hluav taws xob ntawm chitosan fiber, txhim kho kev ua tau zoo tshwj xeeb, xws li kev tiv thaiv hluav taws xob ntawm cov tawv nqaij ntawm cov khaub ncaws tiv thaiv thiab lwm yam khoom siv tiv thaiv kev siv muaj kev cia siab zoo.
Qhov thib peb, cov microfibers bio-based muaj cov qauv tsim nyog, ntau yam kev siv, lub zog zoo thiab hnav tsis kam, thiab muaj txiaj ntsig zoo thiab kev txhawb nqa.
