24-36h is set to get nanometer feather down azelon film.
It is poured into according to different needs in different molds in step 3), the nanometer feather down protein fiber of different-thickness is made
Film is tieed up, preferred thickness is 1.5mm.
Compared with prior art, compound lye system is used in the present invention, is stirred under 20-25 DEG C of cryogenic conditions
Feather down is dissolved, dissolution system provided by the invention can be sufficiently destroyed the Hyarogen-bonding between feather down fibril, and retain albumen
Disulfide bond pattern, provide the foundation for the formation of nanometer fibril, while reducing single aqueous alkali and feather down albumen is divided greatly
The degradation of son, stablizing component has uniform protein dissolution system effect, avoids generating excess destruction, system to protein partial structurtes
Standby feather down fibril distribution is more uniform, and fibrillar size distribution is concentrated；The dissolution rate of the technology mesoptile suede is higher than 98%, almost
Noresidue, the process advantages such as high, energy-saving with dissolution rate, the feather down for dissolving preparation has nanometer fibril pattern, through certainly
Right drying or freezing film forming, can prepare a nanometer feather down azelon film, have higher hydrophilicity.
