Description
Technical field
The invention belongs to Textile Engineering field more particularly to a kind of superhigh temperature dyeing sides for being modified poly- fragrant oxadiazoles fiber
Method.
Background technique
Poly- virtue oxadiazoles fiber can be widely applied to fire-retardant demand as a kind of novel heat-resistance and flame-retardant fiber
The industries fabric field such as electric power, petroleum, army and police, fire-fighting, the anti-flammability of poly- virtue oxadiazoles fabric is outstanding, thermal stability is good and hand
Sense is comfortable.Fiber applied to fabric field needs good dyeability to cope with different fields and wear operating condition, gathers
Fragrant oxadiazoles fiber has certain stainability, commonly uses disperse dyes to dye, and chromatography is more complete, and fragrant oxadiazoles poly- at present is fine
Dimension is mainly using the high-temperature pressure dyeing method at 130 DEG C similar with terylene, since poly- fragrant oxadiazoles fiber is heat resistance fiber,
Its heat resistance is very excellent, and glass transition temperature is up to 400 DEG C or more, therefore in common high-temperature pressure dyeing condition
Under, it is difficult that the strand of poly- fragrant oxadiazoles fiber is made to generate loosening, dyestuff is not easily accessible inside fiber molecule chain, to make dyestuff
Into, thus the dyefastness especially light fastness of the poly- fragrant oxadiazoles fiber dyed under common high-temperature pressure dyeing method compared with
It is low, it is not able to satisfy special industry such as public security, fire-fighting, army etc. to the color fastness demand of fabric.Add a certain proportion of aliphatic
Diacid monomer shell is modified poly- fragrant oxadiazoles, the thermal decomposition temperature and vitrifying temperature of modified poly- fragrant oxadiazoles polymer
Degree is declined, and is deteriorated to the tolerance of organic solvent, and dyeing difficulty is improved.Present invention employs superhigh-temperature and-pressures
Dyeing and combine suitable textile auxiliary, improve modified poly- fragrant oxadiazoles fiber dye-uptake and dyefastness to reach.
Summary of the invention
In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a kind of superelevation for being modified poly- fragrant oxadiazoles fiber
Temperature dyeing method makes the strand of modified poly- fragrant oxadiazoles fiber have a degree of expansion to loosen after pre-treating technology,
Then dyeing process is carried out at higher temperatures, and dye molecule is able to improve dyeing effect and color well into fibrous inside
Fastness.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of superelevation temperature dyeing method being modified poly- fragrant oxadiazoles fiber, its main feature is that carrying out in accordance with the following steps:
S1: fiber to be dyed is placed in dye vat by pre-treatment one, carries out dyeing pre-treatment, by the advanced soft water of bath raio 1:20,
Soap flakes washing, drain after heat preservation 20-30 minutes are added when being warming up to 60-80 DEG C, then is washed 10-15 minutes into soft water overflow, takes out
Fiber drying；
S2: the fiber after clean drying is placed in another dye vat, pretreating reagent is added in dye vat, close by pre-treatment two
It is warming up to 85-95 DEG C under the conditions of closing to fiber treatment 20-40min, takes out fiber drying；
S3: dyeing auxiliaries, dyestuff, high temperature levelling agent is added in dyeing in high pressure dye vat, by bath raio 1:20 by the fibre after drying
Dimension is placed in high pressure dye vat, is warming up to 170-220 DEG C with the heating rate of 2 DEG C/min, is kept the temperature 90min；Then it cools the temperature to
Normal pressure is rinsed 3-4 times after drain with clear water；
Step 4: post-processing adds lye and sodium hydrosulfite to be reduction cleaning 20-25min at 70 DEG C, after rinsed with clear water it is dry
Only, it is eventually adding suitable softener processing；Fiber drying is taken out after drain, is dried in baking oven later.
Further, pretreating reagent described in the pre-treatment two is the mixing of dimethyl sulfoxide and N-Methyl pyrrolidone
Solvent.
Further, the proportion of the mixed solvent of the dimethyl sulfoxide and N-Methyl pyrrolidone is 1:9-5:5.
Further, dyeing auxiliaries described in the staining procedure is acetophenone and sulfolane mixture.
Further, the proportion of the acetophenone and sulfolane is 3:7-7:3.
Further, the poly- fragrant oxadiazoles fiber of the modification is poly- for the modification containing certain proportion aliphatic diacid monomer shell
Fragrant oxadiazoles fiber is prepared by adding a certain proportion of aliphatic diacid monomer shell in the poly- fragrant oxadiazoles fiber of production.
Compared with prior art, it is an advantage of the invention that after pre-treating technology, make modified poly- fragrant oxadiazoles fiber
Strand has a degree of expansion to loosen, and then carries out dyeing process in superhigh-temperature and-pressure and in conjunction with suitable textile auxiliary,
Dye molecule is able to improve Dye up-take and dyefastness well into fibrous inside.
