Problems solved by technology

[0006] Although the industry has provided some methods for the reuse of recycled fiber materials, the biodegradable, hydrophilic, cool, and drape characteristics of the resulting silk or textile silk products are still not ideal, and they are mostly used in staple fiber products , not suitable for long filament

Embodiment Construction

[0011] General fibers can be divided into natural fibers and man-made fibers. Natural fibers exist in nature, and can be divided into plant fibers, animal fibers and mineral fibers according to different sources; while man-made fibers refer to processed fibers, which can be processed from natural raw materials (such as modal fibers, rayon fibers, etc.) Cell fiber, etc.), can also be synthesized by chemical methods (for example: polyester fiber, nylon, etc.).

[0012] Sources of recycled fiber material can be recycled natural fibers and recycled man-made fibers. Recycled natural fibers can be processed recycled cotton, recycled wood pulp, recycled paper pulp, recycled hemp (such as: recycled flax, recycled ramie and recycled jute) and other recycled natural fibers containing natural plant fibers. The source of these natural plant fibers can be completely or partially from clothing manufacturing residues and / or old clothing, wood pulp, rag pulp, textiles, clothing, cotton, in o...

Abstract

The invention relates to a natural cellulose fiber with recycled cellulose. The natural cellulose fiber is prepared by dissolving recycled fiber slurry in a spinning solution, in the solution, weight percent of recycling natural cellulose fibers is 30-55 wt%. Compared with the natural cellulose fiber which is not added with recycled materials, the natural cellulose fiber disclosed by the invention has the properties of hydrophilicity, cool feeling, drape effect, antistatic property, biodegradability and the like.

Description

technical field [0001] The invention relates to a natural cellulose fiber (Lyocell), in particular to a natural cellulose fiber using recycled materials as raw materials. Background technique [0002] The process of natural cellulose fiber (Lyocell) includes the steps of pulping, dissolving, spinning and washing, that is, the wood pulp is usually dissolved in N-methylmorpholine-N-oxide (NMMO) solvent, and after the spinning step The raw silk is obtained, and the NMMO solvent remaining in the raw silk is washed to remove the residual NMMO solvent to make a natural cellulose fiber product. [0003] Natural fiber finished products can also be divided into staple filaments (Staple) and filament filaments (Filament), but the manufacturing process of the two is still different: the manufacturing process of staple filaments includes cutting, compression, blending, spinning and other processing procedures, right? The requirements for breaking and uniform forming are relatively low;...
