▎ 摘　　要

NOVELTY - Graphene oxide modified nylon material comprises nylon 6, graphene oxide, calcium carbonate, heat stabilizer, and silane coupling agent. USE - The graphene oxide modified nylon material is used for three-dimensional printing in textile (all claimed). ADVANTAGE - The graphene modified nylon material has excellent heat preservation and moisture absorption performance, and excellent moisture absorption and warm-keeping performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a method for preparing the graphene oxide modified nylon material, which involves mixing nylon 6, the graphene oxide, the calcium carbonate, the heat stabilizer and the silane coupling agent, and melt-extruding to obtain the graphene oxide-modified nylon material; and a textile is prepared by three-dimensional printing of the graphene oxide-modified nylon material.
