▎ 摘  要

NOVELTY - A textile article comprises pattern consisting of a composition comprising graphene, where the pattern defines a surface with empty portions on which the composition comprising graphene is not present, and full portions on which the composition comprising graphene is present, the pattern comprising lines that intersect in multiple points and form a network structure, full portions of the pattern occupy from 10-70% surface defined by the pattern and empty portions of the pattern occupy from 90-30% of surface defined by the pattern, the graphene consists of 90% graphene nanoplatelets has a lateral size of (x, y) 50-50000 nm and a thickness (z) of 0.34-50 nm, and the carbon/oxygen ratio is greater than or equal to 100:1. USE - Textile article for use in clothing items such as shirts, T- shirts, jackets, sweatshirt, trousers, shorts, hats, bonnets, socks, shoes, shoe linings, gloves and glove linings (all claimed). ADVANTAGE - The textile article has ensuring breathability and is simple. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) an item of clothing comprising textile article (2) a method for preparing textile article, which involves providing a composition comprising 10-40 wt.% polymeric binder, 1-15 wt.% compatibilizing solvent for the polymeric binder, 1-8 wt.% thickener, 1-20 wt.% graphene consisting of 90% graphene nanoplatelets has a lateral size (x, y) of 50-50000 nm and a thickness (z) of 0.34-50 nm, and the carbon/oxygen ratio is greater than or equal to 100:1, 17-87 wt.% water, the composition having a viscosity of 4000-30000 cPs, applying the composition on a flat textile article with the method of screen printing to a pattern defining a surface with empty portions, the composition comprising graphene is not present, and full portions on which the composition comprising graphene is present, where the full portions occupy 10-70% surface defined by the pattern and the empty portions occupy 90-30% surface defined by the pattern, and heating the textile article at an increasing temperature between 120-180 degrees C for a time of between 1-10 minutes.
