Problems solved by technology

[0004] Regenerated cellulose composite fiber is a kind of cellulose fiber with a wide range of uses. It has good mechanical properties and hygroscopicity, but it does not have functional properties.
The traditional functional regenerated cellulose composite fibers are mainly realized by adding additives to the regenerated cellulose composite fibers or by modifying the fibers. However, the regenerated cellulose composite fibers prepared by this method are not functionally washable. The pollution caused by post-processing is relatively serious, so the application of regenerated cellulose composite fibers is limited

Description

technical field [0001] The invention relates to a composite fiber and a preparation method thereof, in particular to a golden graphene oxide regenerated cellulose composite fiber and a preparation method thereof. Background technique [0002] Graphene is a single-layer carbon atom material peeled off from graphite. Carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure. It is the thinnest, hardest, and best-conducting material known to mankind. Material. Graphene has excellent mechanical, optical and electrical properties, and its structure is very stable. So far, researchers have not found the absence of carbon atoms in graphene. The links between carbon atoms are very flexible, harder than diamonds, and stronger than the world's The best steel is 100 times higher. If you use graphene to make a packaging bag, it will be able to bear about two tons of items, almost completely transparent, but extremely dense, impermeable, airtight, e...
