▎ 摘　　要

NOVELTY - Fabric comprises a graphene sea wool fabric, a graphene honeycomb layer, a hollow insulating layer and an encryption lock temperature layer from up to down in turn. The graphene honeycomb layer comprises 0.01-5 wt.% graphene. The hollow insulating layer is provided with heat insulating material. The weight parts of the encrypted surface layer is 30-70 wt.% of the graphene wool fabric. The encrypted surface layer is used for locking the temperature and preventing temperature loss. USE - Used as Hamb fabric. ADVANTAGE - The Hamb fabric has a compact structure, and adopts the corresponding materials to improve the heat preservation and air permeability of the fabric, can solve the problems of warmth, ventilation and comfort without wearing too thick in winter and keep the temperature of the human body and clothing consistent in a short time, has the effect of promoting human microcirculation and long-term wear can properly alleviate the health problems caused by the poor microcirculation of the human body.
