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