Problems solved by technology

However, synthetic fibers will release toxic substances during the degradation and decomposition process, and recycling is difficult, which can easily cause "secondary pollution".
[0006] Although viscose fiber has the above-mentioned series of advantages, its disadvantages are also obvious: the strength of viscose fiber is low, especially the wet strength is poor, only more than half of the dry strength, it cannot be scrubbed strongly when washing, and the service life is short The shrinkage rate of viscose fiber is high, and the appearance of the fabric after washing is not ideal; the elasticity of viscose fiber is poor, and it is easy to deform when worn, causing wrinkles, especially the elbow and knee parts of the clothes will have local arching, which will affect the appearance of the fabric

Abstract

The invention discloses a high-strength viscose fiber and a production method thereof, which are characterized in that the viscose fiber is formed by mixing bacterial cellulose and viscose spinning solution, wherein the content of the bacterial cellulose in the viscose fiber is 1 to 10 percent. The production method comprises the following steps: the flake bacterial cellulose is pre-processed, and then the flake bacterial cellulose after the preprocessing is smashed with a ball milling method to obtain a micro nano-grade bacterial cellulose powder; the bacterial cellulose powder is added into the viscose spinning solution to be uniformly scattered and defoamed to obtain a spinning solution; and the spinning solution is made into a high-strength viscose fiber. The content of the bacterial cellulose in the viscose fiber is 1 to 10 percent. The viscose fiber which is prepared with the production method has high strength, small shrinkage and good elasticity, can be blended and interwoven with cotton, wool and other synthesized fibers to be used for the fields such as top-grade costume fabric and industrial textiles, and the like.

Description

technical field [0001] The invention relates to the technical field of viscose fiber production, in particular to a high-strength viscose fiber and a production method thereof. Background technique [0002] Viscose fiber is the earliest man-made fiber to achieve industrial production. As early as the end of the 19th century, three British scientists, Cross, Bevan and Beadle, invented the method for preparing cellulose xanthate and applied for a patent for the production process of viscose fiber. For more than 100 years, viscose fiber has been favored by consumers for a long time due to its comfortable wearing performance, and its output has always been the largest among cellulose fibers. Compared with synthetic fibers, the advantages of viscose fiber are mainly reflected in three aspects: Aspects: [0003] 1 Raw materials come from a wide range of sources and are renewable resources. Viscose fiber is a man-made fiber produced from natural cellulose as the main raw material...
