Abstract
The present invention discloses the preprocess method of a kind of aramid fiber dyeing, this preprocess method includes, is immersed by aramid fiber in pretreatment fluid, processes 40 60 minutes at 110 130 DEG C, wherein, described pretreatment fluid contains 2 sulfosalicylic acid acid anhydrides and the zinc chloride of 2 5wt% of 1 3wt%.
Description
Technical field
The present invention relates to the preprocess method of a kind of aramid fiber dyeing.
Background technology
As synthetic fibers, aramid fiber has high intensity and toughness, and excellent high temperature resistant, resistance to acids and bases,
But shortcoming aramid fiber vitrification point is the highest, employing is conventionally synthesized fiber dyeing method dyestuff and is difficult to upper dye, general solution
Method is to use carrier dyeing process, i.e. adds PVOH, butyl benzoate, o-phenyl phenol etc. in dye liquor as carrier, with
Improve the dyestuff dye-uptake to aramid fiber, but the carrier of the method residual will significantly reduce the color fastness to light of fabric, dye
Need after color to wash away the carrier on fiber as far as possible so that color is dim.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that the pretreatment side before the dyeing of a kind of aramid fiber
Method, to improve dye-uptake during aramid fiber dyeing.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of preprocess method of aramid fiber dyeing, including, aramid fiber is immersed in pretreatment fluid, at 110-130 DEG C
Processing 40-60 minute, wherein, described pretreatment fluid contains 2-sulfosalicylic acid acid anhydride and the zinc chloride of 2-5wt% of 1-3wt%.
Further, during pretreatment, bath raio is 1:(20-50).
Compared with existing aramid fiber colouring method, the preprocess method of the present invention can significantly improve and contaminate on the dyestuff of aramid fiber
Rate and color fastness to light, bright in luster.
Detailed description of the invention
Below in conjunction with preferred embodiment, the present invention will be described, it will be appreciated that preferred embodiment described herein is only

After dyeing, K/S value=25, fastness to wet rubbing 3 grades, dry fastness 4 grades, color fastness to light 4 grades.
Embodiment 3
Dyeing: kevlar fabric pretreatment → washing → drying → dyeing → washing → drying
Wherein, during pretreatment, pretreatment fluid is: 2-sulfosalicylic acid acid anhydride 1wt%, zinc chloride 2wt%, and solvent is water, processes
Temperature 120 DEG C, 60 minutes time, bath raio 1:50.
During dyeing, formula for dye liquor: Disperse Red 3B 4wt%, sodium chloride 2wt%, dyeing condition: pH value=4.5(acetic acid is adjusted
Joint), temperature 120 DEG C, 40 minutes time, bath raio 1:20.
After dyeing, K/S value=28, fastness to wet rubbing 4 grades, dry fastness 5 grades, color fastness to light 5 grades.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
