Problems solved by technology

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, even the smallest atomic size Helium cannot pass through

Abstract

The invention discloses a graphene antibacterial fabric and a preparation method thereof. The graphene antibacterial fabric comprises the following raw materials of 25-65% of common fibers, 30-70% ofgraphene antibacterial fibers, 0.1-5% of oiling agent and 0.1-5% of finishing agent. The invention also provides a preparation method of the fabric, and the method comprises the following steps of step 1, weighing the raw materials; step 2, oiling the common fibers and the graphene antibacterial fiber short fibers by using the oiling agent; step 3, mixing and opening the oiled common fibers and graphene antibacterial fiber short fibers, performing carding to obtain card slivers, performing drawing and drafting twice to obtain drawn slivers, spinning the drawn slivers, and performing twisting to prepare blended yarns; step 4, weaving the prepared blended yarns into a woven fabric on weaving equipment; and step 5, performing after-treatment on the prepared fabric. According to the graphene antibacterial fabric and the preparation method thereof, the common fibers and the graphene fibers are woven into the antibacterial fabric, so that the antibacterial fabric has a good antibacterial effect, and meanwhile, the fabric is low in cost, good in wearability and wide in application prospect.

Description

technical field [0001] The invention relates to an antibacterial fabric and a preparation method thereof, in particular to a graphene antibacterial fabric 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, even the smallest atomic ...
