Description
Technical field
The present invention relates to a kind of colouring method of goat cashmere fabric, particularly relate to a kind of method adopting the dyestuff containing tobacco leaf and stem extraction to dye to goat cashmere.
Background technology
Goat cashmere fabric product in the market, especially natural goat cashmere fabric product, because the color and luster being limited to natural goat cashmere fabric is single, needs to obtain other colors by dyeing mostly.The colouring method of usual employing comprises use chemical synthetic dye and uses vegetable colour.Wherein, use this class colouring method of chemical synthetic dye, due to the painted requirement of chemical dye, the high temperature of more than 90 DEG C is needed in dyeing course, consume energy larger, and owing to usually containing harmful substance in chemical synthetic dye, seriously polluted in dyeing course and after dyeing goat cashmere fabric can be made also may to have harmful effect to human health.And use the traditional plant colouring method of vegetable colour, also also exist that COLOR FASTNESS is not high, color and the problems such as colour system is not abundant, under-supply.
Summary of the invention
For above-mentioned shortcoming of the prior art, the object of the present invention is to provide that a kind of Color is good, the goat cashmere fabric colouring method of environmental protection and energy saving.
In order to realize foregoing invention object, the colouring method of the goat cashmere in the present invention, comprises the steps: a, wetting also modification goat cashmere fabric; B, under the temperature conditions of 30-45 DEG C, use the dye solution containing tobacco leaf and stem extraction to dye to the goat cashmere fabric obtained through step a process, it is surperficial and permeate goat cashmere fabric inside that the duration is enough to make dye solution to be adsorbed on goat cashmere fabric; Be warming up to 65-75 DEG C subsequently, temperature retention time is enough to make color to anchor on goat cashmere fabric thus to the further fixation of described goat cashmere fabric; C, wash the goat cashmere fabric obtained through step b process.
Dye solution is by using the acidic soft water dissolving dye of 30-35 DEG C formulated in independent reaction kettle.The bath raio of goat cashmere fabric and dye solution is 1:10.
In a preferred embodiment, also enzyme cocktail is comprised in described dye solution.Dyestuff can be the AVANI organic dyestuff of Dimora Colours Inc. Company.The weight ratio of dyestuff and goat cashmere fabric is 6:100 to 16:100.
In a preferred embodiment, the duration under the temperature conditions of 30-45 DEG C in step b is the temperature retention time under the temperature conditions of 10-15 minute, 65-75 DEG C is 25-35 minute.And, being warming up to 65-75 DEG C and temperature being raised for the speed by+2 DEG C/min in step b.
In a preferred embodiment, the wetting also modification goat cashmere fabric in step a carries out by being infiltrated by goat cashmere fabric for 15-25 minute in the acidic soft water of 70-80 DEG C.
In a preferred embodiment, the washing in step c comprises: use acidic soft water to rinse with dye solution remaining in removing step b to processing the goat cashmere fabric obtained in step b; And use soft water again to rinse to remove remaining acidic soft water to the goat cashmere fabric after aforementioned flushing.
The present invention has following Advantageous Effects relative to prior art:
Colouring method of the present invention is compared with using the colouring method of chemical dye, and dyeing temperature is low, it is little to consume energy, and the environment friendly and pollution-free and goat cashmere fabric after dyeing of dyeing course is not also containing dangerous substance.
Colouring method of the present invention is compared with using the traditional plant colouring method of vegetable colour, dye at low temperatures and also can obtain the high product of COLOR FASTNESS, and color abundant species, the dye solution simultaneously containing tobacco leaf and stem extraction easily obtains, and also contributes to other purposes developing tobacco plant.
