Abstract

The invention relates to a dyeing method of a polyester-polyamide composite silk fabric and belongs to the technical field of fabric dyeing. The method comprises the steps of treatment before cold piling, open-width vibrated rinsing based on a rotating drum, preshrinking in an overflow vat, pre-setting treatment, dyeing with dispersed dyes, acid overdyeing and setting treatment. According to the method, by utilizing the synergic action of working solutions in each step and the synergic action among the processes in each step, the fabric shows high color fastness to sweat stains, water stains and soaping, so that the fabric has the advantages of high color fastness and full and rich colors.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing, in particular to a method for dyeing polyester-nylon composite silk fabrics. Background technique [0002] Polyester-nylon composite yarn fabric is a fabric made of polyester-nylon composite yarn. Polyester-nylon composite yarn is two polymer melts that are divided by a special distribution plate, and then extruded through the same spinneret hole, that is, it has nylon It has the advantages of wear resistance and high strength, and polyester has the advantages of good elasticity and shape retention. However, due to the imperfect dyeing process of the polyester-nylon composite yarn fabric, the dyeing property and color fastness of the polyester-nylon composite yarn fabric are relatively poor. Contents of the invention [0003] The object of the present invention is to provide a method for dyeing polyester-nylon composite silk fabrics, which has the advantages of high color fastness, full ...
