Abstract
The present invention discloses a kind of preparation method helping dye composition, including, acetophenone, emulsifying agent and dihydroxymethyl dihydroxy ethylidene-urea are added water, is stirred until homogeneous；Wherein, the mass ratio of acetophenone and dihydroxymethyl dihydroxy ethylidene-urea is 1:(0.2 0.5).With existing swelling method or carrier dyeing process, the dye composition that helps of the inventive method gained can significantly improve dye-uptake when aramid fiber dyes, and improve color fastness.
Description
Technical field
The present invention relates to a kind of preparation method helping dye composition.
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, after aramid fiber is pre-processed by the most first sweller of existing solution, then dyes, or employing carrier dyeing process, even so still suffer from 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 method helping dye composition prepared for improving aramid fiber Color.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of preparation method helping dye composition, including, acetophenone, emulsifying agent and dihydroxymethyl dihydroxy ethylidene-urea are added water, is stirred until homogeneous；
Wherein, the mass ratio of acetophenone and dihydroxymethyl dihydroxy ethylidene-urea is 1:(0.2-0.5).
Further, the aqueous solution contains the emulsifying agent of 2-6wt%.
In the aqueous solution, the concentration of acetophenone can be controlled in 10-40wt% as required.
With existing swelling method or carrier dyeing process, the inventive method gained helps dye composition can significantly improve the dye-uptake of dyestuff when aramid fiber dyes, and improves color fastness.
