Application characteristics:
(1)Sericin
is rich of amino acids with polar pendant groups, such as serine
and asparaginic acid. It is a kind of protein with abundant
hydrophilic groups. Because amino acid with hydrophilic polarity
accounts for about *5% in sericin, especially serine which takes up
about *0% of sericin, whose hygroscopicify is *0 times stronger
than glycerol. Thus, sericin, is highly effective in moisture
absorption, moisture, breathable function and antimicrobial
function when used as raw material of cosmetic and chemical fiber
lay material.
(2)The
film-forming property of silk glue on hair is excellent and the
membrane is glossy, while the hair feels good and elastic. It can
not only avoid the direct contact between hair and chemicals that
can damage hair, and it can also increase the elasticity and gloss
of hair. Sericin can form the membranes with certain strength on
the hair surface, which can be used as the hairspray.
(3)Sericin
has an excellent inoxidizability. It can effectively inhibit the
polyphenol oxidase activity in food and is an excellent natural
antioxidant for fat food, which has very prominent value in
developing the additive to extend the refreshing time of dairy
foods.
(4)Using
sericin protein as main raw material, then coating on the fiber,
underwear, bedding, close skin and leather products through the
cross-linking agent, achieving the silky effects like skin caring,
being friendly to skin, antibacterial, comfortable, etc.
