Abstract

The invention discloses a preparation method of an enteromorpha carbon nano material and regenerated cellulose blended fiber. The preparation method is characterized by comprising the following preparation steps of (1), preparing a high-performance enteromorpha carbon nano material by using enteromorpha as a raw material; (2), blending the enteromorpha carbon nano material with a regenerated cellulose spinning solution; (3), spinning the blended spinning solution through a wet-method spinning device, and shaping a fiber through a coagulating bath, so as to prepare the enteromorpha carbon nano material and regenerated cellulose blended fiber. According to the preparation method of the enteromorpha carbon nano material and regenerated cellulose blended fiber, the raw materials are rich in source and low in cost, the method is simple in preparation process, is free from pollution and can be used for quantitative production; the prepared enteromorpha carbon nano material and regenerated cellulose blended fiber is good in antibacterial, adsorptive and deodorant effects, and is higher in added value compared with ordinary regenerated cellulose.

Description

technical field [0001] The invention belongs to the technical field of preparation of blended regenerated cellulose, and in particular relates to a preparation method of Enteromorpha carbon nanomaterial regenerated cellulose blended fiber. Background technique [0002] Regenerated fibers are chemical fibers made from natural polymers by chemical methods, and have basically the same chemical composition as the original polymers. Due to the characteristics of softness, comfort, breathability and environmental protection of regenerated cellulose fiber, the clothes woven by it are favored by consumers all over the world. Due to the reduction of cultivated land and the depletion of oil resources, the output of natural fibers and synthetic fibers will be more and more restricted; while people pay attention to the environmental protection performance in the process of textile consumption, the value of regenerated cellulose fibers has been reconsidered. Know and discover. [0003]...
