棉杆韧皮制备纤维素膜

Preparation of cellulose membrane through cotton stalk bast

以棉杆韧皮为原料,对其进行浸泡、洗涤,然后采用化学方法进行脱胶处理,得到较为纯净的棉杆韧皮纤维,再用铜氨法制取纤维素膜,并对纤维素膜的透水性、透光性及其在土壤中的降解程度进行了测试。

The cotton stalk bast was used as the raw material and it was soaked, washed and degummed with chemical method. Then the pure cotton stalk bast fibers were obtained, and the cellulose membrane was made by copper ammonia method. Finally, the water permeability, transmission of light and the soil degradation degree of the cellulose membrane were tested.
