Abstract
The open a kind of aramid fiber dyeing method of the present invention, including dyeing, wash, drying, during dyeing, adds 1-Phenylethanone. and the dihydroxymethyl dihydroxy ethylidene-urea of 1 3% of 5 10% in dye liquor.With existing swelling method or carrier dyeing process, the inventive method dye liquor adds the dye-uptake of dyestuff when appropriate 1-Phenylethanone. and dihydroxymethyl dihydroxy ethylidene-urea can significantly improve aramid fiber dyeing as the dyeing auxiliaries of dyestuff, and improves color fastness.
Description
Technical field
The present invention relates to a kind of aramid fiber dyeing method.
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, existing solution party
After the most first sweller of method carries out pretreatment to aramid fiber, then dye, or use carrier dyeing process, the most still
There is the problems such as dye-uptake is relatively low, color fastness is poor.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of aramid fiber improving dye-uptake
Dyeing method.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of aramid fiber dyeing method, including dyeing, wash, drying, its feature is, during dyeing, adds in dye liquor
Enter the 1-Phenylethanone. of 5-10wt% and the dihydroxymethyl dihydroxy ethylidene-urea of 1-3wt%.
The mass ratio of 1-Phenylethanone. and dihydroxymethyl dihydroxy ethylidene-urea controls at 1:(0.2-0.5).
Further, dye liquor adds the emulsifying agent of 0.2-1wt%.
With existing swelling method or carrier dyeing process, the present invention adds on the basis of existing aramid fiber colouring method in dye liquor
Appropriate 1-Phenylethanone. and dihydroxymethyl dihydroxy ethylidene-urea, as the dyeing auxiliaries of dyestuff, can significantly improve dyestuff when aramid fiber dyes
Dye-uptake, and improve color fastness.
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
