Daim ntawv thov
- Sericin yog nplua nuj ntawm cov amino acids nrog polar pendant pawg, xws li serine thiab asparaginic acid. Nws yog ib hom protein uas muaj ntau pawg hydrophilic. Vim tias cov amino acid nrog hydrophilic polarity suav txog li 75% hauv sericin, tshwj xeeb tshaj yog serine uas siv li 30% ntawm sericin, uas nws hygroscopicify yog 50 npaug zog dua glycerol. Yog li, sericin, muaj txiaj ntsig zoo hauv kev nqus dej noo, noo noo, ua pa ua haujlwm thiab ua haujlwm tiv thaiv kab mob thaum siv los ua raw khoom ntawm cov khoom siv tshuaj pleev ib ce thiab tshuaj fiber ntau.
- Cov cuab yeej ua yeeb yaj kiab ntawm lo lo ntxhuav ntawm cov plaub hau yog qhov zoo heev thiab daim nyias nyias yog glossy, thaum cov plaub hau zoo nkauj thiab elastic. Nws tuaj yeem tsis tsuas yog zam kev sib cuag ncaj qha ntawm cov plaub hau thiab tshuaj uas tuaj yeem ua rau cov plaub hau puas, thiab nws tuaj yeem ua rau cov plaub hau elasticity thiab gloss. Sericin tuaj yeem tsim cov membranes nrog qee lub zog ntawm cov plaub hau saum npoo, uas tuaj yeem siv los ua cov tshuaj tsuag plaub hau.
- Sericin muaj ib qho zoo heev inoxidizability. Nws tuaj yeem cuam tshuam cov polyphenol oxidase kev ua haujlwm hauv cov khoom noj thiab yog ib qho zoo heev ntuj antioxidant rau cov zaub mov muaj roj, uas muaj cov nqi tseem ceeb hauv kev tsim cov additive kom ncua lub sij hawm refreshing ntawm cov khoom noj mis nyuj.
- Siv cov sericin protein ua cov khoom siv tseem ceeb, tom qab ntawd txheej txheej ntawm fiber ntau, ris tsho hauv qab, ntaub pua chaw, cov khoom siv tawv nqaij thiab tawv los ntawm tus neeg sawv cev sib txuas, ua tiav cov nyhuv silky zoo li kev saib xyuas tawv nqaij, ua phooj ywg rau daim tawv nqaij, tshuaj tua kab mob, xis nyob, thiab lwm yam.
