Abstract
The invention provides a method for non-bath dyeing and stuffing of leather. The process steps comprise retanning neutralization, water squeezing, dyeing and stuffing, out-of-drum and horse stacking, water squeezing, vacuum drying, hanging drying, moisture regaining, milling, surface cleaning, toggling and crush leather obtaining. In the water squeezing step, a passage water squeezing machine is used, and after the water squeezing step, the water content in wet blue leather is 35 to 40 percent. In the method, the dyeing and the stuffing are performed under a non-bath liquid condition, so that under the condition that the dyeing and stuffing effects of the leather are not lowered, the water and the energy are greatly saved; more than 5 tons of water can be saved when one ton of blue wet leather is processed, the discharge of sewage and waste water is reduced; waste water is basically not discharged in the step of dyeing and the stuffing; and thus, the production cost and the environmental protection cost are saved, and water is also saved.
Description
Technical field
The present invention relates to the leather processing technical field, is a kind of method for non-bath dyeing and stuffing of leather specifically.
Background technology
Traditional dyeing stuffing raw materials technology is the blue wet pelt leather behind the shaving, weighs as the materials benchmark process:
Temperature adjustment-70 ℃ hot water temperature adjustment is controlled water to 50-55 ℃, and the raffinate ratio is about 1.5, and promptly surplus water is 150%, and the actual used water amount is 250-300%; Stuffing-ammoniacal liquor 0.5%, dyestuff 0-5% changeed 30 minutes, and fatting agent 18-22% changeed 90 minutes, and formic acid 1% 15 minutes at interval adds at twice and fixes, and rotates then 30 minutes; Washing cooling-normal temperature waterside adds limit control water, and the interior temperature of drum is reduced to below 45 ℃ gradually, and the washing water is 200-300%; Go out drum; Take horse; Water squeezing is stretched; Extension dries dry.Traditional leather coloring stuffing need be carried out under the condition of 1.5-2.5 times of liquor ratio, 50-55 ℃.Temperature adjustment will be used 70 ℃ of hot water, and the water yield of using in the dyeing course is bigger, also can produce industrial wastewater in a large number simultaneously.Leather manufacturing enterprise needs corresponding techniques, finishing agent and personnel to support for sewage disposal, causes production cost to strengthen.
Summary of the invention
Technical problem to be solved by this invention is under the condition of no body lotion, to carry out stuffing dyeing; When not reducing leather coloring oiling effect; Save water and energy and reduce the discharging of sewage, waste water, thereby reduce production costs and the environmental protection cost, a kind of method for non-bath dyeing and stuffing of leather is provided for this reason.
Technical problem of the present invention solves through following technical proposals:
A kind of method for non-bath dyeing and stuffing of leather is characterized in that processing step comprises: retanning neutralization-water squeezing-dyeing and fat-liquoring-go out drum take horse-water squeezing-vacuumize-extension dry dry-soft-crust leather of washing one's face-toggling-process gets damp again-falls.
Through type wringing machine, wet blue moisture 35-40% after the water squeezing are adopted in described water squeezing.
Described dyeing and fat-liquoring is: do not have to bathe, normal temperature is the materials benchmark with the weight of the blue wet pelt behind the shaving,
Fatting agent 20-22% and dyestuff 0-5% are melted with 70 ℃ of hot water, add the high speed rotary drum and rotated 10 minutes, the wet blue rotating speed 45-50 commentaries on classics/min after the adding water squeezing changeed 90 minutes;
Inspection: the dyestuff fatting agent is scattered in leather, evenly absorbed by skin;
10 times of warm water dilutions of formic acid 1.2% usefulness of concentration content 40% slowly add from axis hole while rotating, and are rotated further 30 minutes, and dyestuff, fatting agent, retanning agent and hide fiber are combined securely;
Inspection: the dyestuff fatting agent absorbs fully, the no greasy feeling in surface.
The present invention carries out stuffing dyeing under the condition of no body lotion; When not reducing leather coloring oiling effect; Significantly save water and energy, process 1 ton of wet blue water saving more than 5 tons, and reduce the discharging of sewage, waste water; The basic non-wastewater discharge of dyeing and fat-liquoring operation, thus reduce production costs and the water saving of environmental protection cost.
