Abstract

The invention discloses a low-temperature dyeing method for an aramid / fire-retardant viscose blended fabric, which comprises the steps of: preparing pre-treatment solution; placing an aramid / fire-retardant viscose blended fabric which needs to be dyed into the prepared pre-treatment solution for pre-treatment; compounding to obtain a dyeing assistant; taking a dye which accounts for certain weight percentage of the pre-treated aramid / fire-retardant viscose blended fabric, then taking a dispersant NNO, an electrolyte, anhydrous sodium carbonate, a wetting agent and the prepared dyeing assistant respectively, and preparing the raw materials into dye solution with the pH value of between 4.0 and 5.5; and placing the pre-treated aramid / fire-retardant viscose blended fabric into the prepared dye solution for dyeing, and then finishing the dyeing of the aramid / fire-retardant viscose blended fabric through the afterfinish. The dyeing method can perform integral one-bath dyeing on the aramid / fire-retardant viscose blended fabric, and ensure that the fabric has bright color, lower cost and unlimited color varieties and the fabric has better homochromatism.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to a low-temperature dyeing method, in particular to a low-temperature dyeing method of an aramid / flame-retardant viscose blended fabric. Background technique [0002] Aramid / flame-retardant viscose blended fabric is a new type of high-performance heat-resistant and flame-retardant blended fabric, which has the properties of fire prevention, heat resistance and flame retardancy. [0003] The aramid fiber in the aramid / flame-retardant viscose blended fabric is composed of amide groups and benzene rings. The stable skeleton structure endows the fiber with excellent chemical stability, thermal stability, high strength, and high modulus. . Its macromolecular structure is compact, its crystallinity is relatively high, its glass transition temperature is about 270°C, and it has no affinity group. The dye is basically not dyed by conventional dyeing methods. At present,...
