Method of preparing rayon staple by benne stalk

Abstract

The invention relates to a method for using pedaliin stem to prepare adhesive staple fiber, comprising that preparing pedaliin stam adhesive slurry and using said slurry to prepare adhesive staple fiber. The first step comprises that preparing material, degelatinizing, beating, refining, dechlorinating, acid treating, and softening. And the second step comprises that feeding slurry, immerging, compressing, aging, cooling, sulfidising, dissolving, filtering, ripening, defoaming, filtering, spinning, beaming drawing, following treating, circling and drying. The invention has the advantages that the resources are abundant, with low cost, while the prepared fiber has high quality, high mechanism strength, soft face, or the like.

Description

technical field [0001] The invention relates to a process for producing viscose fiber pulp by using flax whole stalks, and further spinning to produce viscose fiber. Background technique [0002] Viscose fiber is based on natural cellulose. Traditional viscose fiber is made of coniferous wood. Due to the shortage of raw materials and the innovation of pulping technology, some hardwood, cotton linters, and hemp materials are also used. In the production of viscose fiber pulp, the use of coniferous wood and hardwood as raw materials may involve tree felling, which will affect the environment and destroy natural ecology; therefore, the application of some new raw materials will have broader prospects. Flax is a kind of flax, which is rich in resources in Inner Mongolia, Gansu, Ningxia, Qinghai, and Hebei. Flax belongs to oil crops and is mainly used for oil extraction. Textiles are of great importance. [0003] After searching, no method for preparing flax whole stalk viscose...
