Abstract
The invention discloses a dyeing method for sheep skin and belongs to the field of leather dyeing. The method comprises the steps of washing for the first time, retanning, washing for the second time, stacking, standing, hanging and airing, softening, stretching, ironing and dimensioning. Before the washing step, the method also comprises the following steps of: (1) skin placement: putting sheep skin dyed with a ground color into a drum, and laminating at least two pieces of sheep skin one by one, wherein a grain surface of the sheep skin faces up; (2) adding normal-temperature water into the drum, and rotating the drum for one to three circles; (3) dissolving a dye in the water, adding the dissolved dye into the drum, rotating the drum for one to three circles, and standing; and (4) adding formic acid and a color fixing agent into the drum, forwardly rotating the drum for one to three circles, reversely rotating the drum for one to three circles, and standing. By adoption of the method, a plurality of pieces of sheep skin which are laminated in the drum cannot be uniformly contacted with the dye, so patterns which are formed are irregular and natural.
Description
Technical field
The present invention relates to a kind of sheepskin colouring method, belong to the leather coloring field.
Background technology
The artificial dyeing flower complex process of tradition sheepskin, operation is various, can not produce in enormous quantities, and this brings very big difficulty to factory.Though in the existing technology of producing the drum dyeing method is arranged, it is of the same colour uniformly all to adopt dyestuff that sheepskin is dyed, the flower type is dull, can not produce the colored type of nature.
Summary of the invention
The technical problem that the present invention will solve provides a kind of sheepskin colouring method, and the sheepskin of piling up together in the rotary drum of the present invention can not contact with dyestuff uniformly, and formed like this pattern is irregular, flower type nature.
The technical scheme that the present invention taked is: a kind of sheepskin colouring method; May further comprise the steps: washing for the first time, retanning, wash, take horse for the second time, leave standstill, hang dry in the air, fall soft, stretch, ironing and row's chi, further comprising the steps of before washing for the first time:
(1) pendulum skin: the sheepskin grain that will dye background color is put into rotary drum up, one pile one, puts two at least;
(2) in rotary drum, add normal-temperature water, change 1～3 circle;
(3) water melts dyestuff, and the dyestuff that melts is joined changes 1～3 circle in the rotary drum, leave standstill;
(4) in rotary drum, add formic acid and color-fixing agent, rotary drum is just changeing 1～3 circle that reverses again behind 1～3 circle, leaves standstill.
The normal temperature water yield that adds in the step (2) in the rotary drum is that every 100kg sheepskin adds 700～900kg normal-temperature water.
In rotary drum, add normal-temperature water in the step (2) and change 1 circle.
In the step (3) dyestuff that melts is joined commentaries on classics 1 circle in the rotary drum, leave standstill 30min.
Rotary drum is just changeing 2 circles that reverse again behind 2 circles in the step (4), leaves standstill 20min.
Every 100kg sheepskin adds 0.7～1.2kg formic acid.
Every 100kg sheepskin adds 2.5～3.5kg color-fixing agent.
Every 100kg sheepskin need add dyestuff 1.5～2.5kg.
Water with 10～15 times of dyestuff quality melts dyestuff.
Dyestuff and color-fixing agent are industry commercially available prod commonly used, and wherein dyestuff can be selected the golden yellow G of ACID DYES, the modern GR of Neihuang County and red B for use.Color-fixing agent is a cyanamide polymer class color-fixing agent, and can select model for use is the color-fixing agent of R4B.
Adopt the beneficial effect that technique scheme produced to be: the processing step when the present invention dyes for table; The rotary drum of putting into one pile one of sheepskin adds normal-temperature water and turns around, and has the water of part can guarantee that the sheepskin of piling up together is not scattered between two adjacent skins; Thereby two adjacent skins can not touch dyestuff uniformly after the adding dyestuff; The centre has part to contact with dyestuff, has part not contact by dyestuff, therefore can form the irregular colored type of nature.
