Abstract
The invention relates to a dyeing and finishing process, and especially relates to a leather acidic dye dyeing process comprising process steps that: blank leather is dyed; color fixing is carried out; water washing is carried out; and the obtained material is air-dried. The process is characterized in that water content of the blank leather is controlled at 60-70%; acidic dye dyeing is adopted in the dyeing process, and the material is rotated for 1h in a rotation drum; and formic acid is added during the color fixing step.
Description
Technical field
The present invention relates to a kind of dyeing and finishing technology, relate in particular to a kind of leather acid dyeing technique.
Background technology
Along with the raising of people's living standard, people pursue the softness, plentiful, comfortable of leather more.Traditional painted difficulty of leather coloring technique is large, in the material that selectively gentle, permeability is high emphatically, autotelic reinforcement tanning, in technological operation, emphasis point is in neutralization, so that whole skin degree of neutralization uniformity opened fiber channel, create good condition for later dyeing, stuffing, finally make evenly deep and thorough, soft, plentiful, consolidation of colored leather.
Summary of the invention
The invention provides a kind of technique of using acid dyeing, is that the leather colouring is more even, and feel is better.
The technical scheme that invention solves the problems of the technologies described above is as follows: a kind of leather acid dyeing technique, and its technological process is: crust leather → dyeing → fixation → wash → dry is characterized in that: described crust leather moisture control is at 60-70%; Acid dyeing was adopted in described dyeing, rotary drum transfer 1 hour; Described fixation adds formic acid.
The invention has the beneficial effects as follows: the present invention makes the quality of the dyeing of leather accomplish to spare, thoroughly, only, and does not damage fiber strength, has shortened simultaneously technological process.
The specific embodiment
Below principle of the present invention and feature are described, institute only gives an actual example and to be used for explanation the present invention, is not be used to limiting scope of the present invention.
A kind of leather acid dyeing technique, its technological process is: crust leather → dyeing → fixation → wash → dry is characterized in that: described crust leather moisture control is at 60-70%; Acid dyeing was adopted in described dyeing, rotary drum transfer 1 hour; Described fixation adds formic acid.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
