Abstract

The invention relates to the field of fur dyeing and in particular relates to a novel small-bath-ratio fur dyeing method. A device adopted in the novel small-bath ratio fur dyeing method is a drum; the novel small-bath-ratio fur dyeing method comprises the following steps: step one, feeding water and fur dyeing auxiliaries into the drum; second two, putting dry fur in the drum and rotating for 10-15 minutes; step three, adding a dye according to dyeing requirements and then continuously rotating until even dyeing is achieved; and step four, adding formic acid to the drum until the PH value of the solution is in the range of 3.2 to 3.8 and then continuously rotating for 30-60 minutes; if the dyeing requirements are met, directly taking out the fur and carrying out spin-drying; if the dyeing requirements are not met, repeating the step three and the step four, and then taking out the fur and carrying out spin-drying after the dyeing requirements are met. The novel small-bath-ratio fur dyeing method is characterized in that the adopted bath ratio is in the range of 3-7, and is greatly reduced compared with the bath ratio of 20-30 in a traditional process, and therefore, the water consumption in the dyeing process is greatly reduced, the cost is reduced and the economic performance is improved, meanwhile, the processing time is shortened and the energy consumption is reduced, and moreover, the fur dyeing quality can be improved, the pollution on a dermal plate is low and the color fastness of the fur is high.

Description

Novel little liquor ratio fur colouring method

Technical field

The present invention relates to fur colouring art, a kind of novel little liquor ratio fur colouring method.

Background technology

Under the staining technique integral level of fur industry is relatively low, the fur product overwhelming majority (more than 90%) is required for through dyeing, so the dyeing process output value is big.Existing dyeing level of relative is relatively low, and the water consumed in dyeing course and the amount of other energy are big, especially water；In existing dyeing, the amount of water needed for 1 kilogram of dried bark reaches 20-30 kilogram, and when dyeing, temperature needs at about 75 DEG C, and dyeing temperature is high, and energy resource consumption is big.

Summary of the invention

The invention aims to solve the deficiency of above-mentioned technology and a kind of consumption that can effectively reduce water in dyeing course is provided and the novel little liquor ratio fur colouring method of dyeing temperature can be reduced.

In order to achieve the above object, the novel little liquor ratio fur colouring method designed by the present invention, the equipment of employing is rotary drum；The first step, puts into water and fur dyeing assistant in rotary drum, and temperature is promoted to 60-70 DEG C, and rotary drum turns to water and mixs homogeneously with fur dyeing assistant；Second step, then put into dried bark, rotate 10-15 minute；3rd step, dyestuff is added according to coloration requirements, the dyestuff that powder dye need to carry out spraying or use particle dye to be directly placed at rotary drum by spray equipment after opening by the aquation of more than 90 DEG C in rotary drum adds in district, rotates 30-60 minute the most continuously to even dyeing；4th step, then addition formic acid is rotated further 30-60 minute after reaching 3.2-3.8 to solution pH value in rotary drum；If reaching coloration requirements, the most directly going out skin and drying；If not up to coloration requirements, then need to repeat above-mentioned 3rd step, the 4th step is added dyestuff and adjusted coloured light, dry to going out skin after reaching coloration requirements；Wherein: the amount of the water needed for 1 kilogram of dried bark is 3-7 kilogram, the amount of the fur dyeing assistant needed for 1 kilogram of dried bark is 4-20 milliliter.

Rotary drum used in technique scheme is Patent No.: 2014201342209, and patent name is: the all-in-one in energy-efficient low emission fur polychromatic dyeing all-in-one.

Technique scheme, use rotary drum as dyeing installation, control suitable temperature, in dyeing course, dyestuff is sprayed on fur by the way of spray uniformly, can make to dye in the case of little liquor ratio dyes more uniform, it is achieved thereby that the feasibility of little liquor ratio dyeing, reduce the amount of the water that unit dried bark is consumed, the temperature relative reduction simultaneously dyeed, energy resource consumption can be reduced, the dyeing cost being significantly reduced on the whole, can reduce the Colour Difference time simultaneously, improves working (machining) efficiency.

Novel little liquor ratio fur colouring method obtained by the present invention, its liquor ratio used is 3-7, compares the 20-30 of traditional handicraft, and the amplitude of reduction is big, greatly reduces the water consumption in dyeing course, reduces cost, increases the benefit；Shorten process time simultaneously, reduce energy resource consumption；And fur dyeing quality can be improved, dermatotome pollutes light, and skin is high by color fastness.

Detailed description of the invention
