Dyeing Process of Reactive Dyes with High Color Fastness to Perspiration

Abstract

The invention relates to the technical field of dyeing and finishing, in particular to a dyeing process of reactive dyes with high color fastness to light and perspiration. The dyes used are Norwich EC-R blue, Norwich EC-2R yellow and red dyes; the amount of red dye When ≤0.5%owf, use AVITERA®Light Red SE red; when the amount of AVITERA®Light Red SE red>0.5%owf, replace it with AVITERA®Cardinal SE red dye. The invention provides a dye combination capable of obtaining high color fastness to light and perspiration. Utilizing the difference in performance of each dye, different dye combinations are adopted according to the amount of dye used during dyeing. Each dye combination not only has excellent color fastness, but also has good compatibility. The color rate can meet the needs of various colors, the color reproducibility is good, and it is not easy to stain other fibers. The color fastness to light and perspiration can reach above level 3-4 after the second stage of exposure, and the color of the fabric is basically unchanged.

Description

Dyeing process of reactive dyes with high light perspiration fastness technical field The present invention relates to dyeing and finishing technical field, be specifically related to a kind of reactive dye dyeing process of high light perspiration color fastness. Background technique [0002] The advantage of natural fiber clothing is that it is hygroscopic and breathable, skin-friendly and soft, and the disadvantage is that it is easy to fade. lining for summer Products such as clothing, T-shirts and casual pants are very prone to accidents due to direct contact with the sweaty skin of the human body and exposure to the sun. Fading or discoloration of the top part seriously affects the wearing effect of consumers, which makes us pay attention to the light and sweat resistance in summer products. Color fastness is a key focus in summer. Judging from the data of light-sweat composite color fastness testing in recent years, the light-sweat fastness The fabrics or clot...
