Spin material:

Collagenous, chitin fiber, Salt alginate fiber, vinylon, Kevlar, PAN, PVC, viscose rayon, Lyocell, Modal, Tencel, Newcel, chitosan fiber, Soybean protein fiber , milk protein fiber and so on.

Process route:

Reaction tank(1)(material polymerization，conduct oil)——reaction tank(2)（mixer and deaeration,conduct oil）——Spin pump(conduct oil)——Candle filter(conduct oil)——Dry-jet spinneret (or wet-jet spinneret,conduct oil)—— coagulating bath(with heating, conduct oil)—— 5 godets drawing(1)——Drawing bath(1)——5 godets drawing(2)——Drawing bath(2)——5 godets drawing(3)——Wash(with heating water)——Strong wind quit water(temperature 50℃)——Hot wind shaping box((temperature 100-250℃)—— 5 godet guide yarn——Finish application——Winding.
