Inorganic salts are ammonium chloride, sodium chloride, any one in sodium acetate.
Step 2, kevlar fabric pre-processes:
According to kevlar fabric and pre-dyeing treatment agent mass ratio 1:20~50, kevlar fabric is placed in 60 DEG C~90 DEG C steps 30~60min is handled in 1 pre-dyeing treatment agent being prepared, then room temperature is washed, 70 DEG C~90 DEG C drying.
Step 3, it dyes:
According to kevlar fabric and dye liquor mass ratio 1:20~50, dye liquor will be placed in by the pretreated kevlar fabric of step 2 In, in 120 DEG C~140 DEG C 30~60min of dyeing time, then successively carry out hot water wash, soap, hot water wash, cold water are washed, are dried It is dry.
Wherein dye liquor is made of following raw material according to mass percent: dyestuff 2~4%, promotor 3~7%, levelling agent 0 ~1%, surplus is water, and the sum of above constituent mass percentage is 100%.Dyestuff is the dye of positive ion or disperse dyes；Promote Agent is aramid fiber deep-dyeing agent (commercially available), methyl benzophenone, any one in methyl hydroxybenzoate；Levelling agent is commercial goods.
Hot water temperature is 80 DEG C~90 DEG C during hot water wash；
During soaping, the dosage of soap powder is 1~3g/L in soap lye, and temperature of soaping is 80 DEG C~90 DEG C, and the time of soaping is 5 ~15min；
Cold water, which is washed, to be referred to and is washed with room temperature；
Drying temperature is 70~90 DEG C.
Step 4, it arranges:
Kevlar fabric after step 3 dyeing is put into finishing fluid and is padded, then dries at 70 DEG C~90 DEG C, then exists Be formed 3~5min at 180 DEG C~210 DEG C.
Wherein finishing fluid is made of following raw material according to mass percent: oxidation cross-linked dose 3~6%, inorganic dyestuff 1~ 3%, natural polysaccharide compound 0~1%, oxidant 0~1%, surplus is water, and the sum of above constituent mass percentage is 100%.

The present invention is effectively increased by aramid fiber pre-treating technology, dyeing, postfinishing process, mutual coordinated The light fastness of aramid fiber dyeing fabric.Aramid fiber pre-treating technology is to improve the physical method that fiber is contaminated on dyestuff, by aramid fiber Fabric carries out pre-treatment while ensure that fiber strength does not damage, and increases color depth, improves the K/S value of fabric； Aramid fiber macromolecular is set to generate hole in moment by the way that certain auxiliary agent is added in dyeing course, so that dyestuff be enable to quickly enter Fibrous inside improves dye level, guarantees the light fastness under fabric color depth heavy colour；Finishing technique can make aramid fiber dyeing Fabric light fastness further increases, to be applicable in the aramid fiber dyeing fabric that outdoor study requires high fastness.
Fig. 1 is the scanning electron microscope (SEM) photograph of aramid fiber surface after pre-processing in the method for the present invention, it can be seen from the figure that passing through Pretreatment improves the surface roughness of aramid fiber, increases fibre diameter, and surface relief is uneven, and the specific surface area of fiber increases Greatly, so that the physical absorption ability of fiber and dyestuff improves, to improve dyeability.
Fig. 2 is the influence curve figure of dyeing promoter type and dosage to kevlar fabric dye level, EA-1, DCK-2, V50 be respectively methyl benzophenone be, methyl hydroxybenzoate, aramid fiber deep-dyeing agent.The effect of promotor mainly improves the movement of aramid fiber macromolecular State moves molecule at a certain temperature, and moment generates hole, and the dyestuff of promotor carrying at this time enters fibrous inside, It realizes and contaminates purpose on dyestuff, since fiber surface roughness increases, the adsorption capacity of dyestuff and fiber increases, on more dyestuffs Fiber is contaminated, so that dye level is deepened.In figure, EA-1 color depth is maximum, illustrates the compound effect with ketone group class formation Good, color is deeper better to light fastness raising.
Fig. 3 is influence curve figure of the finishing technique to kevlar fabric dye level.Since aramid fiber itself contains amino, centainly The solarization time will lead to fiber xanthochromia, while the physical absorption easily photooxidation that fiber and dyestuff occur leads to light fastness Very poor, certain chemical assistant and organic pigment, which is added, can increase fabric surface color depth, under certain condition effectively resistance Ultraviolet light is kept off to dyestuff photooxidation, to effectively improve dyed fabric light fastness.Therefore, inorganic pigment concentration increases, K/S value Increase, dyed fabric light fastness improves.
The light fastness of kevlar fabric under different process is compared, result is as shown in the table:
Influence of 1 different process of table to aramid fiber colour fasteness to sunlight
As can be seen from the table, as the ultraviolet irradiation time increases, the kevlar fabric solarization of above-mentioned 3 kinds of different process processing Fastness is declined, and the fall through aramid fiber dyeing fabric post-treatment is minimum, can satisfy light fastness requirement.
