Molekyulu ya Hyaluronic acid (HA) ili ndi magulu ambiri a hydroxyl ndi magulu ena a polar, omwe amatha kuyamwa madzi pafupifupi kuwirikiza 1000 kulemera kwake ngati "sponji ya molekyulu". Deta ikuwonetsa kuti HA imayamwa madzi ambiri pansi pa chinyezi chochepa (33%), komanso imayamwa madzi ochepa pansi pa chinyezi chachikulu (75%). Kapangidwe kake kapadera kamasintha malinga ndi zofunikira za khungu m'nyengo zosiyanasiyana komanso m'malo osiyanasiyana a chinyezi, kotero imadziwika kuti ndi chinthu chabwino kwambiri chonyowetsa khungu. M'zaka zaposachedwa, ndi kusintha kwa ukadaulo wopanga komanso kufalikira kwa ntchito zosamalira khungu za HA, makampani ena anzeru ayamba kufufuza njira zokonzekera nsalu za HA.

Kuphimba pansi

Njira yopangira ma padding ndi njira yopangira yomwe imagwiritsa ntchito chomaliza chokhala ndi HA pokonza nsalu pogwiritsa ntchito ma padding. Njira zenizeni ndikulowetsa nsalu mu yankho lomaliza kwa kanthawi kenako nkuitulutsa, kenako nkuidutsa mu kufinya ndi kuumitsa kuti pomaliza pake ikonze HA pa nsaluyo. Kafukufuku wasonyeza kuti kuwonjezera HA pomaliza nsalu zolukidwa za nayiloni sikukhudza mtundu ndi kulimba kwa nsaluyo, ndipo nsalu yothiridwa ndi HA imakhala ndi mphamvu yonyowetsa. Ngati nsalu yolukidwayo ikakonzedwa kukhala yopyapyala yochepera 0.13 dtex, mphamvu yomangirira ya HA ndi ulusi ikhoza kukonzedwa, ndipo mphamvu yosunga chinyezi ya nsaluyo ingapewedwe chifukwa cha kutsuka ndi zinthu zina. Kuphatikiza apo, ma patent ambiri akuwonetsa kuti njira yopangira ma padding ingagwiritsidwenso ntchito pomaliza thonje, silika, nayiloni/spandex blends ndi nsalu zina. Kuwonjezera kwa HA kumapangitsa nsaluyo kukhala yofewa komanso yomasuka, ndipo ili ndi ntchito yonyowetsa komanso kusamalira khungu.

Kutsekeka pang'ono kwa kapisozi

Njira ya microcapsule ndi njira yokulunga HA mu microcapsules ndi chinthu chopanga filimu, kenako n’kukhazikitsa microcapsules pa ulusi wa nsalu. Nsalu ikakhudzana ndi khungu, microcapsules imaphulika pambuyo pokangana ndi kufinya, ndikutulutsa HA, zomwe zimapangitsa kuti khungu lisamavutike. HA ndi chinthu chosungunuka m’madzi, chomwe chidzatayika kwambiri panthawi yotsuka. Chithandizo cha microencapsulation chidzawonjezera kwambiri kusunga kwa HA pa nsalu ndikuwonjezera kulimba kwa ntchito ya nsalu. Beijing Jiershuang High-Tech Co., Ltd. idapanga HA kukhala nano-microcapsules ndikuyiyika pa nsalu, ndipo kuchuluka kwa chinyezi chobwezeretsa nsalu kunafika pa 16%. Wu Xiuying adakonza microcapsule yokhala ndi HA, ndikuyiyika pa polyester yopyapyala ndi nsalu za thonje loyera kudzera mu resin yolumikizira kutentha kochepa komanso ukadaulo wokonza kutentha kochepa kuti nsaluyo isunge chinyezi kwa nthawi yayitali.

Njira yophikira

Njira yophikira imatanthauza njira yopangira filimu yokhala ndi HA pamwamba pa nsalu, ndikukwaniritsa zotsatira zosamalira khungu pokhudza nsaluyo ndi khungu lonse panthawi yovala. Mwachitsanzo, ukadaulo wodzipangira wamagetsi wodzipangira wokha umagwiritsidwa ntchito kuyika njira yolumikizirana ya chitosan cation ndi njira yolumikizirana ya HA pamwamba pa ulusi wa nsalu ya thonje. Njirayi ndi yosavuta, koma zotsatira za nsalu yosamalira khungu yokonzedwayo zitha kutayika mutatsuka kangapo.

Njira ya ulusi

Njira ya ulusi ndi njira yowonjezera HA mu gawo la polymerization ya ulusi kapena kupota dope, kenako kupota. Njirayi imapangitsa HA kukhalapo osati pamwamba pa ulusi wokha, komanso kufalikira mofanana mkati mwa ulusi, ndi kulimba kwabwino. MILAŠIUS R et al. adagwiritsa ntchito ukadaulo wa electrospinning kugawa HA mu mawonekedwe a madontho mu nanofibers. Kuyesera kwawonetsa kuti HA imakhalabe ngakhale itanyowa m'madzi otentha a 95 ℃. HA ndi kapangidwe ka unyolo wautali wa polymer, ndipo malo ochitira zachiwawa panthawi yopota angayambitse kuwonongeka kwa kapangidwe kake ka molekyulu. Chifukwa chake, ofufuza ena adakonza kale HA kuti ateteze, monga kukonzekera HA ndi golide kukhala tinthu tating'onoting'ono, kenako nkuibalalitsa mofanana. Pakati pa ulusi wa polyamide, ulusi wa nsalu zokongoletsa wokhala ndi kulimba kwambiri komanso kogwira mtima ungapezeke.
