[0011] General fibers can be divided into natural fibers and artificial fibers. There is natural fiber in natural fibers, depending on the source, can be divided into plant fibers, animal fibers and mineral fibers; the fiber made of the artificial fiber refers to the fibers made of processing, can be processed by natural raw materials (for example: modal fiber, Lai Saier fibers, etc.), can also be synthesized by chemical methods (eg polyester fibers, nylon, etc.).
[0012] The source of recovery fibrous material can be recovered natural fibers and recycled artificial fibers. The recovery of natural fibers can be treated recycled cotton, recovered wood pulp, recovered pulp, and recovered numb (such as recycling linen, recycling ramie and recovery jute), including natural plant fibers. Natural fiber. The source of natural plant fibers can be completely or partially from clothing to produce residual objects and / or old clothing, wood pulp, cutting pulp, textile, clothing, cotton to save resources and re-use the recovery fiber material.
[0013] Natural cellulose fiber is a human fiber, and the method for producing natural cellulose fibers is usually (1) in a N-methyl morphine-N-oxide (NMMO) solvent, Classic fibrus slurry; (2) a spinning solution is discharged through a membrane squeezed machine; (3) After the process of spinning, washing, drying, etc., is wound therethrough; (4) finally The yarn is woven into the fabric, and then further processed into commodity applications in clothing, furniture, medical equipment, etc., selling in the market.
[0014] Due to environmental awareness, green environment, sustainable business issues have been continuously concerned, and traditional natural cellulose fiber products are still required to have a large amount of natural raw materials, and therefore, the present invention provides a natural cellulose with recovery cellulose. The fibers can be mainly derived from second-hand textiles, such as recycling old clothes, furniture or other abandoned textiles to obtain recovery fibrous materials, and preparing cellulose slurry in recovery fibrous materials to obtain recovery cellulose.
[0015] The natural cellulosic fibers of recovery cellulose can be supplied with a natural cellulose fiber process, and the mixed native wood pulp is dissolved in the NMMO solvent in the NMMO solvent. Further, the woven solution is further prepared. Cut the wire. Further, purification and removal impurities are purified and removed to enhance the stability of the spinning of the recovery cellulose slurry.
[0016] The invention has a natural cellulosic fiber of the recovery cellulose which is used in a spinning solution, and the weight percentage of the recovered cellulose slurry is 30% to 55%, so that the wire made of only the original wood pulp is used. Or better features. Preferably, the use of a solution-based mass of 35% to 55% in the spinning solution is used to recover the cellulose slurry. Preferably, the use of a solution of 43% to 52% of the solution mass based on a solution mass is used in the spinning solution. The concentration of cellulose long chain molecules in the spinning solution used is high, and the viscosity of the spinning solution is improved to avoid the case where the wire break during the spinning process.
[0017] In summary, the present invention has the following benefits: 1. Natural cellulosic fibers of the present invention, can be applied to long fibers producing longofibers; 2. Natural cellulose fibers that are not added to recover, this The natural cellulosic fibers of the invention also have hydrophilic, cool sensation, vertical, antistatic, biological decomposition, and the like; 2. Natural cellulose fibers of the present invention, due to the use of higher proportional recovery materials, can help achieve "Low pollution, recyclable, provincial resources" environmental protection, sustainable development goals.
[0018] The above disclosure is only the preferred feasible embodiment of the present invention, and is not limited thereto, and therefore, the equivalent techniques of the present invention are intended to use the equivalent techniques of the present invention, all of which are included in the claims of the present invention. In the range.
