Molekyuru yeHyaluronic acid (HA) ine huwandu hwakawanda hwema hydroxyl groups nemamwe mapoka e polar, ayo anogona kunwisa mvura kanenge ka1000 kupfuura huremu hwayo se "molecular sponge". Data inoratidza kuti HA ine hunyoro hwakawanda pasi pehunyoro hushoma (33%), uye hunyoro hushoma pasi pehunyoro hwakanyanya (75%). Hunhu uhwu hwakasiyana hunoenderana nezvinodiwa neganda mumwaka yakasiyana nenzvimbo dzakasiyana dzehunyoro, saka inozivikanwa sechinhu chakakodzera chehunyoro hwechisikigo. Mumakore achangopfuura, nekuvandudzwa kwetekinoroji yekugadzira uye kufarirwa kwezvishandiso zvekuchengetedza ganda zveHA, mamwe makambani matsva akatanga kutsvaga nzira dzekugadzirira machira eHA.

Kuputira

Nzira yekuputira inzira yekugadzirisa inoshandisa mushonga wekupedzisa une HA kurapa jira nekuputira. Matanho chaiwo ndeekunyika jira mumushonga wekupedzisa kwenguva yakati wozoriburitsa, wobva waripfuudza nekurisvina nekuomesa kuti ugadzirise HA pajira. Zvidzidzo zvakaratidza kuti kuwedzera HA pakupedzisa machira akarukwa nenylon warp hakuna zvakunokanganisa pavara nekusimba kwejira, uye jira rakarukwa neHA rine moisturizing effect. Kana jira rakarukwa rikagadziriswa kusvika pafiber linear density iri pasi pe0.13 dtex, simba rekusunga reHA nefiber rinogona kuvandudzwa, uye kugona kwekuchengetedza hunyoro kwejira kunogona kudzivirirwa nekuda kwekusuka nezvimwe zvinhu. Pamusoro pezvo, ma patent mazhinji anoratidza kuti nzira yekuputira inogona kushandiswawo pakupedzisa donje, sirika, nylon/spandex blends nemamwe machira. Kuwedzerwa kweHA kunoita kuti jira rive rakapfava uye rakanaka, uye rine basa rekunyorovesa nekuchengetedza ganda.

Kuvharwa kwekapisiyumu

Nzira ye microcapsule inzira yekuputira HA muma microcapsules uchishandisa chinhu chinogadzira firimu, wobva wagadzirisa microcapsules pamachira ejira. Kana jira rakabatana neganda, microcapsules dzinoputika mushure mekukweshana nekudzvanya, uye dzoburitsa HA, dzinoita kuti ganda rirambe richichengetwa. HA chinhu chinonyungudika mumvura, chinorasika zvakanyanya panguva yekuwacha. Kurapa kwe microencapsulation kuchawedzera zvakanyanya kuchengetedza HA pajira uye kunatsiridza kugara kwenguva refu kwejira. Beijing Jiershuang High-Tech Co., Ltd. yakagadzira HA kuita nano-microcapsules ndokuishandisa pamachira, uye mwero wekuwana hunyoro hwemachira wakasvika kupfuura 16%. Wu Xiuying akagadzira microcapsule ine HA, ndokuiisa pamachira epolyester akatetepa nemachira edonje akachena kuburikidza ne resin ine temperature yakaderera uye tekinoroji yekugadzirisa temperature yakaderera kuti jira rirambe richichengetwa kwenguva refu.

Nzira yekuputira

Nzira yekuputira inoreva nzira yekugadzira firimu rine HA pamusoro pejira, uye kuwana simba rekuchengetedza ganda nekubata jira zvizere neganda panguva yekupfeka. Semuenzaniso, tekinoroji yekuzvisanganisa yega yega inoshandiswa kuisa chitosan cation assembly system pamwe neHA anion assembly system pamusoro pemachira edonje. Nzira iyi iri nyore, asi simba rejira rekuchengetedza ganda rakagadzirwa rinogona kurasika mushure mekusukwa kakawanda.

Nzira yefayibha

Nzira yefiber inzira yekuwedzera HA muchikamu che polymerization yefiber kana kutenderera dope, uye wozotenderera. Nzira iyi inoita kuti HA isangova pamusoro pefiber chete, asiwo iparadzirwe zvakaenzana mukati mefiber, nekugara kwenguva refu. MILAŠIUS R et al. vakashandisa tekinoroji ye electrospinning kuparadzira HA muchimiro chemadonhwe mu nanofibers. Kuedza kwakaratidza kuti HA inoramba iripo kunyangwe mushure mekunyikwa mumvura inopisa ye95 ℃. HA chimiro che polymer chain refu, uye mamiriro ekunze ane simba panguva yekutenderera anogona kukonzera kukuvara kwechimiro chayo chemamorekuru. Nokudaro, vamwe vaongorori vakagadzirira HA kuti vaidzivirire, sekugadzirira HA negoridhe kuita nanoparticles, uye vozoiparadzira zvakaenzana. Pakati pe polyamide fibers, cosmetic textile fibers ine kugara kwenguva refu uye kushanda zvakanaka inogona kuwanikwa.
