[0029] Flame-retardant blended fiber A kind of dyeing process of flame-retardant blended fiber, it comprises the following steps:

[0030] Step 1, desizing treatment: Add the flame-retardant blended fiber to the desizing aqueous solution at 50-60 ° C, keep it warm for 10-24 hours, and then wash it with water at 50-70 ° C to remove the surface residue;

[0031] Step 2, rinsing treatment: take the flame-retardant blended fiber treated in step 1, add it to the rinsing aqueous solution at 95-100°C, keep it warm for 0.5-2hr, and then wash at 50-70°C to remove the surface residue;

[0032] Step 3, depilation treatment: take the flame-retardant blended fiber treated in step 2, and remove the surface hairiness;

[0033] Step 4, the first dyeing treatment: take the flame-retardant blended fiber treated in step 3, add it to 15-35°C water, gradually raise the temperature of the water bath to 100-102°C, and add dye when the water bath is 68-71°C And when the water bath is 95-100°C, add d...

Abstract

The invention aims to provide a dyeing process of flame-retardant mixed fiber. The dyeing process includes following steps: adding the flame-retardant mixed fiber into a desizing water solution of 50-60 DEG C, holding the temperature, and washing with water at 50-70 DEG C; adding the flame-retardant mixed fiber that is desized into a rinsing water solution of 95-100 DEG C, holding the temperature, and washing with water at 50-70 DEG C; unhairing; adding the flame-retardant mixed fiber that is unhaired into water of 15-35 DEG C, rising the temperature to 100-102 DEG C, adding dye at 68-71 DEG C, adding a dye auxiliary at 95-100 DEG C, and holding the temperature at 100-102 DEG C; rising the temperature to 130-135 DEG C, and holding the temperature at 130-135 DEG C; lowering the temperature to 75-80 DEG C; taking out the flame-retardant mixed fiber, and soaping the flame-retardant mixed fiber at 75-80 DEG C; taking the flame-retardant mixed fiber dyed for the first time, padding the flame-retardant mixed fiber in dye liquid, and air-drying at high temperature; padding the flame-retardant mixed fiber in color fixing liquid, and performing saturated steaming at high temperature; subjecting the flame-retardant mixed fiber after saturated steaming to water washing at 10-15 DEG C, acetic acid neutralizing, soaping at 85-90 DEG C and water washing at 15-35 DEG C sequentially; taking the flame-retardant mixed fiber after being dyed, and subjecting the flame-retardant mixed fiber to air finishing and full decatizing sequentially. The dyeing process has the advantage that 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 blended fibers. Background technique [0002] In some fields such as firefighting clothing, flame-retardant blended 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 kind of viscose flame-retardant blended fiber, which i...
