Peb paub tias hyaluronic acid, raws li cov khoom lag luam zoo nkauj, muaj cov nyhuv moisturizing thiab moisturizing thiab yog siv dav hauv ntau yam khoom tu tawv nqaij xws li daim npog ntsej muag, lub ntsej muag cream thiab moisturizers. Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho ntawm kev ua neej nyob, tib neeg txoj kev nrhiav cov khaub ncaws tsis yog tsuas yog zoo nkauj thiab sov so, tab sis kuj xis nyob, ib puag ncig tus phooj ywg thiab noj qab nyob zoo. Raws li kev ua haujlwm textile nrog tus nqi ntxiv, nws yog ntau thiab nrov dua. Thaum hyaluronic acid ntsib textiles, nws yuav tsim dab tsi?
Dab tsi yog hyaluronic acid thiab nws cov nyhuv yog dab tsi?
Hyaluronic acid, tseem hu ua hyaluronic acid, yog ib tug loj polysaccharide muaj li ntawm ob disaccharide units, D-glucuronic acid thiab N-acetylglucosamine. Hyaluronic acid yog ib qho tseem ceeb ntawm kev sib txuas cov ntaub so ntswg xws li tib neeg cov khoom sib txuas, lub cev vitreous, cov kua dej synovial, thiab ua lub luag haujlwm tseem ceeb hauv kev tswj cov dej, tswj qhov chaw extracellular, tswj osmotic siab, lubricating, thiab txhawb kev kho cell.
Dab tsi yog hyaluronic acid textiles? Nws cov txiaj ntsig yog dab tsi?
Hyaluronic acid textiles xa mus rau cov ntaub ntawv uas muaj hyaluronic acid los ntawm kev txuas hyaluronic acid molecules rau cov fibers los ntawm cov txheej txheem tom qab ua tiav. Piv nrog rau cov tshuaj pleev ib ce, lub sij hawm sib cuag ntawm textiles thiab tib neeg lub cev yog ntev dua thiab qhov chaw sib cuag yog loj. Hyaluronic acid, ib qho kev ua haujlwm ntxiv hauv cov ntaub, tuaj yeem ua tiav kev kho mob ntawm daim tawv nqaij kom ntau dua. Yog li ntawd, Hyaluronic acid textiles yog nrov nrog cov neeg siv khoom. Hyaluronic acid molecule muaj ntau pawg hydroxyl thiab lwm pawg polar, uas tuaj yeem tsim ib qho kev sib txuas ntawm peb-dimensional honeycomb network qauv ntawm qhov tsis tshua muaj siab, ua Hyaluronic acid, zoo li "molecular sponge", tuaj yeem nqus tau thiab tswj tau 1000 npaug ntawm nws tus kheej. qhov hnyav ntawm cov dej, yog li ua rau cov ntaub mos mos thiab xis nyob, thiab ua kom cov tawv nqaij noo thiab tsis qhuav. Hyaluronic acid yog thoob ntiaj teb lees paub tias yog qhov zoo tshaj plaws humectant, nrog lub npe qhuas ntawm "natural moisturizing factor", thiab nws kuj yog glycosaminoglycan, uas tsis muaj hom tshwj xeeb, zoo sib xws, thiab yuav tsis ua rau muaj kev fab tshuaj thiab teeb meem kev nyab xeeb.
hyaluronic acid textiles tsim thiab ua li cas?
Tam sim no, muaj plaub txoj kev npaj tseem ceeb ntawm cov ntaub uas muaj hyaluronic acid: dip dov method, microcapsule method, txheej txheej thiab fiber ntau. Txoj kev dipping yog ib hom kev ua haujlwm uas siv cov khoom tiav uas muaj hyaluronic acid los kho cov ntaub los ntawm txoj kev dipping. Txoj kev no yog qhov yooj yim, yooj yim thiab siv tau, thiab tau siv dav rau tam sim no. Microcapsule method yog ib txoj hauv kev uas siv cov ntaub ntawv ua yeeb yaj kiab los qhwv hyaluronic acid hauv microcapsules, thiab tom qab ntawd kho cov microcapsules ntawm cov ntaub fibers. Txoj kev no tuaj yeem tau txais cov ntaub nrog kev ruaj ntseg ntev. Cov txheej txheem txheej feem ntau tso hyaluronic acid rau ntawm qhov chaw fiber ntau los ntawm electrostatic self-assembly technology, uas yog qhov nyuaj dua thiab siv tsawg dua. Cov txheej txheem fiber ntau yog ib txoj hauv kev ntxiv hyaluronic acid rau hauv cov tshuaj spinning stock thiab ces spinning. Txoj kev no tuaj yeem tau txais hyaluronic acid textiles nrog kev ua haujlwm siab dua, thiab tseem yog cov kev taw qhia ntawm kev ua haujlwm loj ntawm hyaluronic acid textiles yav tom ntej.
Yuav ua li cas txheeb xyuas seb puas muaj hyaluronic acid hauv textiles?
Feem ntau, cov ntaub ntawv uas muaj hyaluronic acid tsis tuaj yeem paub qhov txawv ntawm qhov pom, thiab nws kuj nyuaj rau kev paub qhov txawv ntawm tes txoj kev xav. Yog li ntawd, nws yog ib qho tsim nyog los tshuaj xyuas seb cov ntaub ntawv puas muaj cov khoom siv moisturizing hyaluronic acid nrog kev pab los ntawm cov cuab yeej precision. Tam sim no, muaj peb txoj hauv kev tseem ceeb los txheeb xyuas cov ntsiab lus ntawm hyaluronic acid: colorimetry, ntim tsis suav nrog kev ua haujlwm siab ua kua chromatography thiab kev ua haujlwm siab ua kua chromatography. Cov txheej txheem colorimetric muaj qhov tshwj xeeb tsis zoo thiab yooj yim rau kev cuam tshuam, uas tuaj yeem ua rau cov txiaj ntsig tsis raug thiab cov txiaj ntsig tsis zoo. Qhov ntim tsis suav nrog kev ua haujlwm siab ua kua chromatography feem ntau muaj qhov ntsuas siab siab, uas muaj feem xyuam rau cov tshuaj pleev ib ce nrog cov ntsiab lus siab ntawm hyaluronic acid, tab sis tsis yog rau textiles nrog cov ntsiab lus tsawg. Kev ua haujlwm siab ua kua chromatography tam sim no muab faib ua acidolysis - precolumn derivatization-siab ua kua chromatography thiab enzymolysis - ua haujlwm siab ua kua chromatography. Ntawm lawv, acidolysis - precolumn derivatization-kuaj kev ua haujlwm cov kauj ruam yog cumbersome, thiab reproducibility ntawm kev ntsuam xyuas yuav tsum tau txhim kho, yog li no txoj kev no yog siv tsawg; Vim tias qhov tshwj xeeb zoo ntawm cov enzyme thiab cov khoom siv ib leeg enzymolysis, cov enzymolysis muaj qhov tshwj xeeb muaj zog thiab raug siab, thiab tau maj mam siv rau kev tshuaj xyuas cov ntsiab lus ntawm hyaluronic acid hauv cov qauv nyuaj.
