Problems solved by technology

[0005] It can be seen from the above prior art that sweet sorghum stalks can be used to prepare textile materials such as paper and fiber through processes such as crushing, kneading, and extrusion. However, the current existing technologies are too backward and do not address the characteristics of sweet sorghum stalks. Batch processing, simple preparation of finished products, low added value, limited economic value

Abstract

The invention provides a novel composite fiber based on sweet sorghum skin fiber and a preparation method thereof. The preparation method comprises the following steps: (1) removing leaves of sweet sorghum stalks which are about 15-20 cm long, cleaning the sweet sorghum stalks, obtaining sweet sorghum skin and flesh pith containing normal juice through a separator, performing squeezing separation on the flesh pith containing the normal juice to obtain stalk flesh residue, cleaning and drying the stalk flesh residue, and obtaining stalk residue powder after smashing and filtration; (2) refining the sweet sorghum skin into skin fiber strips, placing the skin fiber strips in a solvent to undergo ultrasound scattering, washing and drying to obtain the skin fiber; (3) evenly mixing the stalk residue powder and the skin fiber; after distilled water is added for swelling for a period of time, adding chitosan and sodium alginate, performing high-speed stirring at a high temperature, performing vacuum defoamation, and performing filtration to obtain spinning solution; (4) causing the spinning solution to form nascent fiber through a wet spinning technology, and obtaining the composite fiber based on the sweet sorghum skin fiber through drafting, washing and winding. The fiber is a composite fiber integrating toughness, antibiosis, anti-inflammation and greenness.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a composite fiber based on sweet sorghum sheath fiber and a preparation method thereof. Background technique: [0002] Sorghum is the fifth largest crop in the world and one of the ancient crops. It is the main food crop in arid and semi-arid areas. Its origin and spread have experienced a long history. Sorghum has high photosynthetic efficiency, large biological and economic output, and strong stress resistance and adaptability. Sorghum contains antibacterial ingredients such as tannin, which can replace the use of other antibiotics. Moreover, the grain shells of sorghum varieties are rich in color and the pigment content varies greatly. Sorghum products have a wide range of uses and high economic value. [0003] Sweet sorghum, also known as reeds and millet, is a variety of sorghum for seeds, mainly used for stems, and belongs to the original ecological ...
