A kind of disperse dye composition and application thereof
Technical field:
The present invention relates to a kind of disperse dye composition, particularly a kind ofly be applicable to dispersed dye and the application thereof that has good Color under the alkaline condition.
Background technology:
At present, the dyeing of trevira, more employing dispersed dye dye under solutions of weak acidity, and the defective that this dyeing process exists is: refining, the alkali decrement of trevira before dyeing, and soap boiling and reduction clearing after the dyeing are all carried out under alkaline condition.Therefore, cause easily when dyeing in the acid bath that dyeing is uneven, dye bath pH value fluctuation range is big, can cause the variation of coloured light, the dyeing poor reproducibility.
Also there is part producer to adopt dispersed dye under alkaline condition, to dye, dispersed dye can effectively be removed slurry, finish on the polyester textile in alkaline condition dyeing, overcoming other degradation production such as polyester oligomer separates out in acid bath and produces the shortcoming of dying defect, bring the effect that cloth cover is clean and tidy, Fabric Style is good simultaneously, often do not need reduction clearing can satisfy the fastness requirement.
But, at present, it is very few really to be applied to carry out under the alkaline condition painted dispersed dye, trace it to its cause: the one, existing alkaline dispersed dye have bigger restriction on textile dyeing is used, still can not be applicable to entirely widely to wash, wash/cotton and wash spandex and, ultra-fine fibre etc., and obtain good Color; The 2nd, existing alkaline dispersed dye are applicable to the restriction of dyeing, and pre-treating technology and dyeing need separately carry out, and energy consumption and environmental pollution are bigger; The 3rd, the suitability aspect of existing alkaline dispersed dye and other reactive dyestuffs has bigger restriction.
Have based on this, the applicant makes this invention, be intended to improve a kind of disperse dye composition, have under the alkaline condition and can obtain good Color, and the lining that is applicable to various styles as wash entirely, wash/cotton and wash spandex and, ultra-fine fibre etc., and can be suitable for one-bath dyeing technology separately or with other reactive dyestuffs, and can obtain good Color.
