Abstract
A cation modifying method for dyeing cotton yarn features that the cotton yarn is first modified by the quaternary ammonium salt compound containing chloralcohol group or sym-triazine group, and then dyed by reactive dye. Its advantages include high dyeing speed and dyed percentage, low consumption of reactive dye, preventing pollution of waste water to environment, improved quality of cotton fabrics.
Description
The present invention relates to the colouring method of cotton cation modifying.
The used REACTIVE DYES saturation limit of the dyeing of cotton yarn of the prior art is worth less, dyestuff hydrolysis in dyeing course greatly reduces the utilization rate of dyestuff, when dying dark color as colors such as bright red, emerald green orchid, black, not only dye dosage is very big, and relatively more difficult.Reason is that the fiber of yarn fiber element is electronegative because weak disassociation forms, and can give birth to Coulomb repulsion between cellulose and dye molecule, stops the diffusion of dyestuff to fiber, causes dyeing speed slow, and dye-uptake is low.
Purpose of the present invention is intended to overcome the deficiencies in the prior art and provides a kind of dyeing time short, and dye-uptake and degree of fixation are high and the saving cost of dye reduces and the colouring method of the cation modifying of the cotton yarn of minimizing environmental pollution.
The object of the present invention is achieved like this:
A kind of colouring method of cation modifying of cotton yarn is characterized in that earlier cotton yarn being gone again dyeing after modified technique is handled, the technology of modification and prescription are:
Modifier 5-40 grams per liter
Caustic soda 1-20 grams per liter
After 70 ℃ of dippings flooded 60 minutes in 30 minutes or 60 ℃, wash with water near neutral.
---described modifier is the quaternary amine salt type compound of response type modifier such as chloride alcohol groups or the quaternary ammonium salt compound that contains cyanuro.
---described dyeing is not add glauber salt promptly not add Na
2SO
4The dyeing of salt.
Be example explanation modification theory and embodiment with response type modifier below:
Under suitable condition, it reacts the hydroxyl on modification and the cellulose fibre, connects cation group on fiber, thereby improves the dyeability of fiber.
As when using reactive dyeing since in the reactive dyestuff molecule except that containing active group, also contain a considerable amount of sulfonic groups, this group is electronegative.In when dyeing, cellulose fibre is because weak disassociation formations-cell-o and electronegative, during with the active group reaction of dyestuff, Coulomb repulsion can take place between cellulose and dye molecule, and the prevention dyestuff is to the diffusion of fiber.Add glauber salt in dyeing course, its effect is exactly to weaken or eliminate above-mentioned electrical charge rejection effect, dyes in the promotion.And it is cotton through after cation-modified, a little less than hydroxyl, be dissociated into the negative oxygen ion, simultaneously also because the modification cotton is positively charged, not only can eliminate the repulsion of cellulose to dyestuff negative electricity group, also can increase the CATION cotton on the contrary to the anionic attraction of dyestuff, increase improves the dyeing rate and the dye-uptake of dyestuff to the affinity of dyestuff.
Embodiment:
Get raw material and be 20 cotton yarns of EPO4 pre-treatment and put into 100 liters of alkali lye that contain 1000 gram caustic soda for 16.7 kilograms, add quaternary amine 2000 grams of the chloride pure gene of response type modifier, wash with water to nearly neutrality after 30 minutes at 70 ℃ of dippings.Then according to a conventional method but do not add glauber salt and dye with REACTIVE DYES.
Remarkable result of the present invention can be as seen from Table 1:
The comparison of dye dosage before and after table 1 modification

| EVE?YW?HE4R | 3.37 | ?5.22 | ?1.49(28.5％) |
As can be seen from the above table, after the modification, the dye-uptake of dyestuff is greatly improved, and the consumption of dyestuff also reduces significantly.From the color of dye bath raffinate, unmodified raffinate color is very dark, the then very slight color after the modification.
The nearly all REACTIVE DYES used to company all is suitable for.
Method of the present invention makes the dyeing speed of REACTIVE DYES accelerate, dye-uptake has raising largely, saves REACTIVE DYES, gets rid of the pollution of glauber salt sewage to environment, and the COLOR FASTNESS and the level-dyeing property of the cotton yarn that is dyed are excellent, thereby have improved the quality and the style of COTTON FABRIC.
