Abstract

The invention discloses a dyeing process for a nylon-cotton fabric. The dyeing process is used for dyeing an undyed nylon-cotton fabric by adopting a one-bath one-step method, and comprises the following steps of S1, putting the nylon-cotton fabric subjected to desizing treatment into a dye vat, and adding a dye fixation accelerant into the dye vat at room temperature for soaking treatment for 1-2 hours, with the use amount of the dye fixation accelerant being 1-5g / L; S2, adding a neutral dye and a reactive dye into the dye vat, adding an acid-base buffer agent to adjust the pH value to be 9.5-10.5, then heating to 96-100 DEG C at the rate of 1-1.5 DEG C / min, carrying out heat preservation dyeing for 15-20 minutes, and then cooling and draining liquid, wherein the use amount of the neutral dye is 0.5-3% owf, and the use amount of the reactive dye is 1-3% owf; and S4, sequentially performing steaming reduction, water washing, oxidation and soaping on the dyed nylon-cotton fabric to enable the dye to fully develop color, and then performing water washing, drying and cloth discharging to finish the whole dyeing process.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a nylon-cotton fabric dyeing process. Background technique [0002] In recent years, nylon and cotton fabric series products have become more and more popular in the international and domestic markets. Nylon fiber has the characteristics of good elasticity, high strength, light weight and wear resistance, and good moisture absorption. Its durability, durability and wear resistance are about 4-5 times that of wool, and it is deeply loved by people. However, nylon fiber is a kind of Hydrophobic fibers feel moisture impermeable and airtight when in use. Cotton fiber is a hydrophilic fiber, which has the advantages of soft hand feeling, good moisture absorption and air permeability, but it is easy to wrinkle and not crisp. Nylon and cotton fibers are blended into nylon and cotton fabrics, which have both the advantages of the two fibers but are complementary to...
