Abstract

The invention discloses an environment-friendly acid black dye composition, which consists of the following components in percentage by weight: 3 to 15 percent of dye component A shown in a formula (1), 38.5 to 52 percent of dye component B shown in a formula (2), 0.2 to 1.0 percent of dye component C shown in a formula (3), and the balance of assistant. The dye composition has super compatibility, has the advantages of wide application range of pH value, high color yield, good level-dyeing property and good various fastnesses during dyeing, has more remarkable advantage in the aspect of water washing fastness, and is an environment-friendly black acid dye with superior performance.

Description

technical field [0001] The invention relates to an environment-friendly acid black dye composition, which is especially suitable for dyeing and printing nylon and wool. Background technique [0002] With the improvement of living standards in recent years, people's awareness of environmental protection has also gradually increased. In the printing and dyeing industry, higher requirements are also provided for the dyeing performance and environmental protection performance of dyes. If you choose one with good dyeing reproducibility and exhaustion rate, excellent wet fastness and light fastness, certain migration and level dyeing properties, economical price, it can be used for nylon microfiber or nylon / Lycra Environmentally friendly acid black dyes for dyeing blended fibers have become a top priority. Although similar products have appeared on the market, their chromatographic range is not wide, the price is expensive or the performance cannot meet the requirements, making i...
