Problems solved by technology

However, the cost of graphene is high, and graphene aqueous solution needs to be prepared; in addition, this method uses padding to coat graphene on the surface of the fabric, so the durability is not high
[0004] In addition, in the article "High temperature thermallyconductive nanocomposite textile by "green" electrospinning" in the 10th issue of "Nanoscale" in 2018, the experimental study constructed a new material through boron nitride (FBN) nanosheets and polyimide (PI) nanofibers. A heat-conducting nanocomposite textile material, the method has cumbersome steps and harsh conditions, which is not conducive to large-scale industrial production; and this method can only prepare heat-conducting filaments, which cannot be realized for the heat-conducting treatment of textiles such as yarns and fabrics
