Description
Technical field
The invention belongs to fabrics printing and dyeing method and technology fields, and aramid fiber can be enhanced to anionic dye dyeing by being related to one kind
The preprocess method of performance.
Background technology
Aramid fiber is a kind of lilion of aromatic rings, and industrialized aramid fiber is mainly aramid fiber 1313 (poly- isophthalic
Two formyl m-phenylene diamine (MPD) fibers) and Fanglun l414 (Fanglun 1414) two major classes.Aramid fiber has height
The excellent performances such as by force, Gao Mo, high temperature resistant, radiation hardness, electrical insulating property, anti-flammability, hot wet migration and chemical stabilization be good.Virtue
Synthetic fibre material is widely used, in addition to being applied to high-temperature-resistant filtering material, electrical apparatus insulation material, honeycomb structure material and fire proofing material etc.
Outside, moreover it is possible to be applied to high-performance apparel material, such as the high-performance of space suit, fire-entry suit, racing car clothes, field operations clothes specific use
Textile.Thus aramid fiber dyeing product is caused increasingly to be valued by people.
However, aramid fiber is to interconnect the linear macromolecule that phenyl is constituted by amido bond.Aramid fiber macromolecular structure is very
Closely, a large amount of amide groups and aromatic rings are contained in molecule, intermolecular hydrogen bonding is more, and cohesive force is big, and fiber swelling is difficult, crystallinity
Height, glass transition temperature is high, and meta-aramid glass transition temperature is up to 270 DEG C, and p-aramid fiber glass transition temperature is up to 350 DEG C, and virtue
Water soluble group is free of in synthetic fibre molecular structure, therefore aramid fiber has that dyeing is difficult, tinctorial yield is low, is difficult to contaminate deep heavy colour.
And when usually aramid fiber uses disperse dyes and cation stain, dyeing temperature is up to 140 DEG C, and it is big, dirty that high-temperature dyeing has energy consumption
Dye is big, requires the problems such as high to dyeing installation.In recent years, there are many dyeing and finishing workers to be dedicated to studying aramid fiber carrier, to improve
The dyeability of aramid fiber.
The method for improving aramid fiber dyeing performance at present mainly has：(1) method of original liquid coloring is used to dye aramid fiber,
But make aramid fiber coloring there are the tone single and inflexible disadvantage of the mode of production relatively by spinning solution method, limit aramid fiber
Extensive use in textile garment field；(2) polar solvent pre-processes aramid fiber, such as uses polar solvent dimethylacetylamide
(DMAc) aramid fiber is handled, aramid fiber intermolecular force is weakened, so that aramid fiber diameter and specific surface area is increased, improves
Aramid fiber dyeing performance, but a large amount of solvent can be remained on aramid fiber after dyeing, need massive laundering to remove residual solvent, and
Solvent is difficult to recycle；(3) dyeing carriers such as acetophenone, benzyl alcohol are used to handle aramid fiber, carrier can be such that aramid fiber is plasticized, and drop
Low-fiber glass transition temperature, while having good dissolubility energy to dyestuff, and then Dye Adsorption can be promoted and diffused into
Fibrous inside.Cationic dyeing is mainly used through the puffing aramid fiber of carrier, or uses disperse dyeing.But it carries
Body generally has special odor, and carrier can also remain on fiber after dyeing, it is necessary to which a large amount of water of application remove residual support.
