Problems solved by technology

[0004] The technical problem to be solved by the present invention is to aim at the shortcomings that the current polyester disperse dyeing and antistatic generally need to be processed in two steps, the process time is long, the cost is high, and the efficiency is low, which is not conducive to the further promotion and application of polyester fabrics. Graphene oxide or its derivatives are added to the dyeing bath of polyester disperse dyes. During the dyeing process, graphene oxide or its derivatives are adsorbed on the surface of polyester fabric and partially reduced. During the reduction cleaning process, graphene oxide or its derivatives are Further reduction has realized the one-bath processing of polyester disperse dyes for antistatic and dyeing, and the antistatic effect has good washability, especially has no effect on fabric handle, shade and fastness, reducing production costs and improving efficiency

Abstract

The invention discloses a one-step processing method of polyester fabrics for antistatic electricity and dyeing. The method comprises the following steps: adding graphene oxide or derivatives thereofinto a dip and pad dyeing bath of a polyester disperse dyes to simultaneously adsorb the graphene oxide and derivatives thereof on the polyester surface in the processing of dyeing the disperse dye and reduce part of the polyester surface, and further reducing the graphene oxide and derivatives thereof in the reducing and washing process. According to the method, a polyester fabric can be subjected to dyeing and antistatic treatment with disperse dye in one bath in one step, so that time is saved, the production efficiency is improved, the antistatic effect has excellent washing resistance, and the fastness, color and hand feeling of a dyed fabric are not influenced.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing, and in particular relates to a polyester fabric antistatic and dyeing one-bath one-step processing method. Background technique [0002] Polyester is the synthetic fiber with the largest output. It is often dyed with disperse dyes. Its good wrinkle resistance and high strength are the first choice for sports fabrics. However, polyester fibers are prone to static electricity due to the lack of polar groups in their molecules, which seriously affects their wearing performance. Polyester fabrics generally require antistatic finishing after they are dyed or printed. [0003] Invention patent CN 104562708 B discloses a preparation method of an antistatic polyester tablecloth, the method firstly passes the polyester tablecloth through Na 2 CO 3 solution, a mixed solution of N-(2-aminoethyl)-3-aminopropyltrimethoxysilane and vinyltrimethoxysilane, and ammonium persulfate solution for cont...
