Abstract

The invention discloses a biodegradable fiber material and a preparation method thereof. The method comprises the following steps: 1) drying, crushing and screening common waterhyacinth to obtain common waterhyacinth powder; 2) successively soaking the common waterhyacinth powder in methanol and acetyldimethylamine to obtain a material A; 3) putting the material A in alkaline liquor to be alkalized and then adding chloroethane to heat the mixture to obtain a material B; 4) irradiating the material B; 5) crosslinking the irradiated material B to obtain a material C; and 6) putting the materialC in a dual screw extruder to be extruded and granulated to obtain the biodegradable fiber material. The fiber material has good biodegradability, can replace plastics partially as a novel green environment-friendly material for manufacturing plastic uptake products, soft packaging materials and the like, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of degradable materials, and in particular relates to a biodegradable fiber material and a preparation method thereof. Background technique [0002] Biodegradable materials refer to materials that can be degraded under the respiration or chemosynthesis of natural microorganisms such as fungi and bacteria. Cellulose is the most abundant natural polymer compound in the world. It is a polymer synthesized by plants through photosynthesis. It has the advantages of renewable, biodegradable, environmentally friendly, and pollution-free. It is an industrial-grade sustainable Primary source of material. [0003] Water hyacinth is a floating herb. Studies have shown that its stems are rich in cellulose, which can be extracted and used to make composite materials. But water hyacinth is listed as one of the most invasive weeds in the world, often due to overgrowth, blocking waterways and affecting traffic. Therefore,...
