Problems solved by technology

[0003] Nylon fiber is a chemical fiber with low cost, good performance and extremely wide uses, but traditional nylon fiber is not functional. With the development of society, traditional nylon fiber can no longer meet people's demand for functional textiles, while graphene emits light Nylon fiber has good antibacterial, far-infrared, anti-ultraviolet, luminous and other functions, and the functionality of the fusion graphene nylon composite fiber is permanent, and will not weaken with the increase in washing times, extending the traditional nylon. The scope of application increases the added value of the product, which satisfies people's demand for healthy and environmentally friendly functional textiles, and the luminous fiber enhances the fiber diversity, and the clothing fabric can be more colorful

Description

technical field [0001] The invention relates to a modified graphene luminescent nylon composite fiber and a preparation method thereof, in particular to a graphene luminescent nylon 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, imper...
