Problems solved by technology

This dyeing process not only has poor dyeing effect, but also takes a long time to process, consumes a lot of water, consumes a lot of electricity and steam, and has poor washing fastness.
At the same time, a large amount of inorganic salts such as sodium sulfate have been added to the dyeing bath, which not only increases the labor intensity, but also causes the ion concentration in the wastewater to be as high as more than 100,000 ppm, and the utilization rate of reactive dyes is low, generally only 60-70%. A large amount of colored wastewater is produced, its chroma exceeds the standard by several thousand times, and the COD value is generally 0.8-30,000ppm

Abstract

The invention discloses a nylon-cotton fabric one-bath dyeing method with an activated dye. The method comprises the steps that a nylon-cotton fabric is soaked into a activated dye liquor, dyeing is conducted under the conditions that the bath ratio is adjusted to be 1:(5-20) and the temperature is 20-30 DEG C, the temperature is raised to 55-75 DEG C, heat preservation is conducted for 5-15 min, then the temperature is raised to 105-125 DEG C, heat preservation is conducted for 30-40 min, 1-5 g/L sodium carbonate is added, and heat preservation is conducted for 5-25 min at the fixing temperature of 60-90 DEG C, wherein the activated dye liquor comprises 1-5% owf of rare earth coordinated microencapsulated activated dye, 5-15 g/L of anhydrous sodium sulphate, 0.5-10 g/L of pH lubricating agent, 0.1-0.3 g/L of hydrozybenzene halogenide and 0.01-0.1 g/L of organic fluoride surface active agent. The dyeing method has the advantages of being high in fixation rate and good in leveling property and is simple in technology and short in dyeing time, the consumption of salt in the activated dye is greatly reduced, and environmental protection is achieved.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a reactive dye one-bath dyeing method for nylon and cotton fabrics. Background technique [0002] Nylon cotton Roman cloth (nylon cotton cloth) dyeing mainly uses reactive dyes to dye cotton and acid dyes to dye nylon, which is widely welcomed and the amount of use is expanding year by year. Reactive dyes are combined with dyed fibers by covalent bonds, and have the characteristics of bright shade, complete color spectrum, simple dyeing process, and excellent color fastness. And the washing fastness is poor. Since reactive dyes are mainly fixed on cellulose fibers under alkaline conditions, and mainly fixed on nylon fibers under acidic conditions, the characteristics of reactive dyes are used in process design to finally achieve the purpose of coloring reactive dyes on two kinds of fibers. . [0003] The existing dyeing of brocade cotton cloth includes the following steps: add ...
