Abstract

The invention relates to blended fibers and a preparation method thereof and belongs to the technical field of blended fibers. In order to overcome the technical defects of low strength and low toughness of cellulose fibers in the prior art, the invention provides blended fibers adopting cellulose as a main component and a preparation method thereof. The blended fibers comprise the following components in parts by weight: 60-80 parts of natural cellulose, 10-15 parts of polylysine, 3-7 parts of polyacrylonitrile, 2-8 parts of polyvinyl alcohol and 0.5-3.5 parts of chitosan. The blended fibers prepared by the formula and the process are excellent in performance, strong in toughness and good in elasticity and can meet the needs of the textile industry.

Description

technical field [0001] The invention relates to a blended fiber and a preparation method thereof, belonging to the technical field of blended fibers. Background technique [0002] With the development and progress of technology and the continuous improvement of people's requirements, fibers of a single material sometimes cannot meet people's needs very well, and various multi-component fibers have emerged as the times require. They have properties that cannot be possessed by fibers of a single material at the same time, and combine the advantages of multiple fibers to provide better performance. The blended fiber can have part of the excellent properties of the two blended components at the same time, and the blended fiber with excellent properties can be obtained by a reasonable combination of properties. The preparation process is simple, and at the same time, the amount of more expensive materials can be reduced and the cost can be saved. [0003] Cellulose is a common n...
