Graphene sleeping bag

Abstract

The invention discloses a graphene sleeping bag. The graphene sleeping bag comprises a sleeping bag body, wherein the sleeping bag body comprises an inner cloth layer, a graphene heating layer and anouter layer; the graphene heating layer is prepared by blending and weaving modified graphene fibers, bamboo charcoal fibers and mosquito-expelling cotton fibers. A preparation method of the modifiedgraphene fiber comprises the following steps of preparing a graphene film at the surface of a metal substrate by a chemical vapor deposition method, cleaning the graphene film by plasma, and graftingthe graphene film with hydroxyl groups, so as to obtain the modified graphene film; mechanically stripping to remove the metal substrate, and twisting the modified graphene film by a gathering and twisting device, so as to obtain the modified graphene fiber. A preparation method of the mosquito-expelling cotton fiber comprises the following steps of soaking cotton fibers into a mosquito-expellingliquid for 24 to 48h, dewatering, cleaning, and drying, so as to obtain the mosquito-expelling cotton fiber. The graphene sleeping bag has the advantages that the warming effect is good, the moistureabsorbing and air ventilating functions are realized, and the risk of heavy humidity in a human body due to high environment humidity is greatly reduced; the physical therapy effect is realized, the mosquitoes can be expelled, the sleeping is promoted, and the comfortability is good.

Description

technical field [0001] The invention belongs to outdoor products, in particular to a graphene sleeping bag. Background technique [0002] With the improvement of people's living standards, outdoor activities have gradually become one of people's main leisure activities, and sleeping bags are indispensable bedding for outdoor camping, and the comfort of sleeping bags has also received more and more attention. Sleeping bags generally include an outer layer, a filling layer and a lining layer, and are usually filled with down or chemical fiber, which has poor thermal insulation effect. Outdoor nighttime temperatures are generally low, so warmth retention is one of the main indicators of sleeping bag comfort. The current sleeping bags are usually used to keep warm, and the humidity is high outdoors at night, which can easily cause moisture intrusion. Among the "six evils" of wind, cold, heat, dampness, dryness, and fire that cause disease, Chinese medicine is most afraid of dam...
