Abstract
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.
