Embodiment Construction
[0067] Compared with traditional chemical methods, the method of using biological enzyme degumming has great cost and energy advantages. In the process of mixing filament and flax fiber for spinning, compared with ordinary hemp fiber spinning, there is no need to add new equipment, only the spinning frame is modified. In terms of energy saving, this project has energy-saving advantages mainly in the degumming step. Next Facing this specific analysis.
[0068] (l) Raw hemp: Compared with chemical degumming, the production rate of raw hemp biological degumming refined and dried hemp can be increased by 3-5%. Calculated by increasing the production rate by 3%, 0.05 tons of raw hemp is used less per ton of refined and dried hemp. At present, the price of raw hemp is 5800 yuan / ton, and the cost of raw hemp can be reduced by 290 yuan per ton of dry hemp.
[0069] (2) Water: After adopting biological degumming, no pickling, no alkali boiling, no bleaching, no pickling, and less wash...
