Dyeing process of fire retardant fibers

Abstract

The invention aims at providing a dyeing process of fire retardant fibers. The dyeing process comprises the following steps: step 1, desizing: adding the fire retardant fibers into a desizing eater solution at 50-60 DEG C, keeping the heat and washing with water; step 2, rinsing: adding the fire retardant fibers subjected to the desizing into a rising water solution at 95-100 DEG C, keeping the heat and washing with the water; step 3, dehairing: taking the rinsed fire retardant fibers and removing hairs on the surfaces of the fire retardant fibers; step 4, dyeing: taking the unhaired fire retardant fibers and adding the unhaired fire retardant fibers into water at 15-35 DEG C; gradually heating a water bath to 100-102 DEG C; adding dyestuff when the water bath is 68-71 DEG C and adding a dyestuff auxiliary agent when the water bath is 95-100 DEG C; keeping the heat at 100-102 DEG C for 0.5-1 hour; gradually heating the water bath to 130-135 DEG C and keeping the heat at 130-135 DEG C for 0.5-1 hour; gradually cooling the water bath to 75-80 DEG C; taking out the fire retardant fibers and soaping at 75-80 DEG C for 0.1-0.5 hour; and step 5, finishing: taking the dyed fire retardant fibers and sequentially carrying out air finishing and full decatizing finishing on the dyed fire retardant fibers. The dyeing process has the advantage that the dyeing effect is improved.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, more specifically, it relates to a dyeing process of flame-retardant fibers. Background technique [0002] In some fields such as firefighting clothing, flame-retardant fibers have always been an important part. The flame retardancy of fibers can be seen from the combustion process, which is to try to hinder the thermal decomposition of fibers, inhibit the formation of flammable gases and dilute flammable gases, change the mechanism of thermal decomposition reactions, block the thermal feedback loop, and isolate the air and thermal environment. To eliminate or reduce the impact of the three elements of combustion (combustible substances, temperature, oxygen), and achieve the purpose of flame retardancy. [0003] The application publication number is CN103614795A, and the Chinese patent on March 5, 2014 discloses a viscose flame-retardant fiber, which is to uniformly add a certain pro...
