Spacing is the 2/3 of wingceltis maximum gauge, and the roller spacing of roll squeezer is reduced 2mm by roller process every time later, until roll squeezer
Roller stop roller process when being smaller than 1.2mm, after each roll-in, the wingceltis after roll-in is used into sodium carbonate-
Sodium bicarbonate buffer system, dodecyl sodium sulfate, water are by weight 5：1：200 solution prepared impregnate 8-10min, then again
It is further processed；
（3）, by step（2）The wingceltis handled well uses compound soak immersion treatment 60-75min at 42-50 DEG C, then
It is stirred using blender, fiber is made to disperse in compound soak, then removed the residue of offscum and floating, then will remain
Remaining fiber is combed, and the compound soak is made using following raw material by weight：1.2 parts of trihydroxy ethylamine oleate soap,
30 parts of 15 parts of ethanol solution, the water of 1.2 parts of dodecyl sodium sulfate, 0.4 part of triethanolamine, volume fraction 78%；
（4）, by step（3）The sodium citrate solution that the fiber handled well is 2% with mass fraction is by weight 1:2 ratio is mixed
It closes, fiber is then broken into the staple fiber that length is 2-15mm using crusher, obtains modified wingceltis hide fiber.
4. a kind of environment-friendly type inorganic agent for treated sewage according to claim 3, it is characterised in that：The carbonic acid
The pH9.2-10.8 of sodium-sodium bicarbonate buffer system.
