Ageing-free washing-free printing technique of diverse dyes

Abstract

The invention discloses an ageing-free washing-free printing technique of diverse dyes and relates to the technical field of printing of textile products. The ageing-free washing-free printing technique of diverse dyes according to the technical scheme is characterized by comprising the steps of pretreating, to be specific, spraying a pre-prepared pretreatment liquid to the surface of a printing grey cloth prior to drying; printing, to be specific, printing the printing grey cloth with ageing-free washing-free printing color paste with a circular screen printer or a flat screen printer or by amanual printing technique, wherein the ageing-free washing-free printing color paste, per 160 parts, comprises, by weight, 5-8 parts of diverse dyes, 60-70 parts of thickeners, 1-2 parts of dyeing accelerants, 0.1-0.5 part of pH regulators, and the balance of deionized water; drying, to be specific, drying at 100-120 DEG C for 2-4 min before discharging from the screen printing machine; and baking, to be specific, baking at 180-200 DEG C for 1-3 min to cause color development. The ageing and washing steps of the conventional printing techniques are omitted herein; the technique of the invention has the advantages of low water consumption, low energy consumption and low emission; the finished product printed via the technique is equivalent to products printed via the conventional printingtechniques in terms of color fastness and color uniformity.

Description

technical field [0001] The invention relates to the technical field of textile printing processing, more specifically, it relates to a disperse dye non-steaming and washing printing process. Background technique [0002] Fabric printing is the process of applying dyes or paints to form patterns on fabrics. The printing process is generally partial dyeing, which requires a certain color fastness. The printing process varies according to the dyes used and the printed gray fabric. [0003] Among them, in the large-scale use of traditional dye printing fabric technology, more and more products are printed with disperse dyes. Common products include printed polyester silk, printed knitwear, printed polyester / cotton cloth and printed vinegar silk fabrics. Products printed with disperse dyes have a mature screen printing process, easy operation, and low cost. Especially the finished product after printing, its color is bright, transparent and bright, elegant and luxurious, the d...
