Description
Technical field
The present invention relates to a kind of polyimide fiber black-dyeing methods, belong to textile dyeing and finishing manufacture field.
Background technology
Polyimides (Polyimide, PI) is a kind of high performance material containing imide ring, has excellent thermostabilization
Property, limit oxygen index has the characteristic that do not melt up to 38% or more, is put out from fire;The glass transition temperature of fiber 300 DEG C with
On, heat decomposition temperature is up to 600 DEG C.Except first, polyimide fiber also has preferable mechanical performance, the polyamides of equal benzene-type
The tensile strength of imine fiber is up to 170MPa, stretch modulus 3.0GPa;Polyimides does not dissolve in common organic solvents, to oxygen
Agent, the stability of reducing agent are high, but intolerant to basic hydrolysis, chemical stability is good.Therefore polyimides can be widely applied to navigate
Sky, space flight, automobile, microelectronics, the various special dimensions such as medical instrument.It is wide that various excellent performances assign polyimide fiber
Application prospect.
Polyimide fiber glass transition temperature is higher, and chemical-resistant reagent has good stability, and causes dyeing and the colorant match of fiber
It is very difficult.At present original liquid coloring method is mostly used in the polyimide of commercialization, but the original liquid coloring method product of fiber
Cost is higher, production is more difficult.In addition to this, the not alkali resistance that can utilize polyimides carries out fiber using alkaline agent
Processing, the content for increasing fiber polarity group achieve the purpose that dyeing to make the effect between dyestuff and fiber enhance.
For polyimide fiber itself in golden yellow, general coloring covers its golden yellow, the color after dyeing completely
It is in the Overlay of yellow and dye colour more, therefore also needs to the golden yellow by itself in terms of polyimides dyeing as three
Primary colors carries out colorant match using other dyestuffs.Additionally as textile, black is most common and most important color, as high property
Energy fiber is mainly used for commercial application just with greater need for black, and there has been no in terms of polyimides colorant match and dye black at present
Document report.
Invention content
