Problems solved by technology

[0002] Graphene polyurethane fabric is one of the common fabrics in the world. Among them, graphene is a new type of nano light material. It not only has a two-dimensional crystal structure of single atomic layer, but also has the advantages of large specific surface area and high strength. It has a two-dimensional planar structure, high reflection efficiency for various types of optical fibers, and good shielding effect. Therefore, graphene polyurethane fabrics are widely used in sunscreen clothing, etc., but due to the imperfect printing and dyeing process of graphene polyurethane fabrics, graphene polyurethane fabrics The color fastness of the fabric is poor

Abstract

The invention relates to a graphene polyurethane fabric printing and dyeing process, which belongs to the technical field of fabric dyeing, including cold pile pretreatment, open-width drum vibration washing, air cylinder pre-shrinkage, pre-setting treatment, weak acid dye dyeing, flexible post-treatment, and setting treatment, and use the synergy between the working fluids of each step and the synergy between the processes of each step to make the fabric show higher color fastness to perspiration, color fastness to water stains, and color fastness to soaping. Moreover, the elastic recovery rate of the fabric is improved, so that the fabric has the advantages of high color fastness and is not easy to be stained with other colors.
