Method for making bamboo fiber

Abstract

The present invention is preparation process of bamboo fiber, including coarse bamboo fiber, refined bamboo fiber and spinnable bamboo fiber. The coarse bamboo fiber is prepared through cutting bamboo, separating bamboo fiber, steaming inside the No. 1 softening liquid and enzyme fermentation; the refined bamboo fiber is prepared through steaming inside the No. 2 softening liquid, enzyme fermentation, rinsing and bleaching, acid treatment, and oil soaking and drying; and the spinnable bamboo fiber is prepared through emulsifying, initial carding, combing and drawing. The bamboo fiber has lignin content lower than 5 %, and has the features of being natural and green, high in strength, high toughness, high brightness and high elasticity.

technical field

[0001] The invention relates to a method for preparing fibers, in particular to a method for preparing bamboo raw fibers. Background technique

[0002] Bamboo is the second largest forest resource in the world. The bamboo forest area in the world is about 20 million hectares, and it is widely distributed, from tropical to subtropical, temperate and even frigid regions. Due to the rapid growth and high economic value of bamboo, a large number of artificial bamboo forests have appeared all over the world. my country is rich in bamboo plant resources, ranking first in the Asia-Pacific region in terms of both the type and area of ​​bamboo. There are about 40 genera and more than 400 species of bamboo in my country. The bamboo forest area is about 7 million hectares, accounting for about 35% of the world's bamboo forest area and 58% of the Asia-Pacific region.

[0003] Bamboo fiber is made of natural bamboo, which is a real environment...
