In head tank, while 1000 r/s are slowly increased to up to constant speed with the rate of 10 r/s, then spinning material tank is spun into centrifugation
Spinneret orifice is opened, and under gravity and centrifugation force effect, spinning solution obtains tunica fibrosa after centrifugal spinning；
Step C anion acarus-proof antibiotic films
It is 0.1MPa that the tunica fibrosa obtained through step B, which is placed in vacuum degree, and temperature is dry in 120-145 DEG C of vacuum drying chamber
8-10h obtains dry tunica fibrosa, then handles dry tunica fibrosa with mite-proofing and antimicrobial sustained-release liquid, obtains anion
Acarus-proof antibiotic film.
