It is secondary, exhaust every time after vacuum tumbling 5-10 minutes, then vacuum pumping, is so circulated 2-4 times so that leather base energy in tumbling procedure
The effect of breathing massage is enough reached, reduction inner material is hardened, makes cortex more soft, is easy to colouring；
(3) the leather base after tumbling is put into the PEG-400 polyglycol solutions that concentration is 30%, 60 points of normal temperature dipping
Clock, then takes out extension on the top of the shelf, to no liquid drippage；Then leather base is paved, fully sprays pretreating agent with spray gun, put
Put more than 80 minutes, then spray another side；
(4) leather base is put into progress dyeing processing in staining reaction kettle, dyeing temperature in the kettle is in 75-90 DEG C, dyeing caldron
Pressure is 15-22MPa, and dyeing time is 20-60 minutes；
Above-mentioned staining reaction kettle uses supercritical CO 2 dyeing kettle, and wherein supercritical carbon dioxide fluid flow velocity is 10
~20g/min.
(5) leather base is taken out after the completion of dyeing and is put into another reactor, steam is then injected into reactor, anti-
Answer the steam temperature in kettle to stop injection steam when reaching 90-110 DEG C, while starting agitating function, be heated evenly material, stir
Mix 20-35 minutes, then water filling is cleaned；The color fastness of leather can be improved using steam heating；
(6) the leather base after cleaning is placed in vacuum and low temperature cold wind drier, be dried under 50-55 DEG C of environment of temperature
Processing, obtains finished product.
Processing is dried from vacuum and low temperature cold air drying technology, so that product keeps preferable pliability, protective coloration
Pool is injury-free, and drying temperature and time are the optimal parameter obtained in substantial amounts of experimental basis, the production obtained under the conditions of this
Quality is preferable, and easily industrialized production.
To obtain good Color, it is necessary to leather base is pre-processed before dyeing, brushing pretreating agent is different
Pretreating agent produces different influences to the definition of dyeing pattern, and by the regulation to inorganic agent viscosity, enables coating very
It is uniformly coated.The proportioning of above-mentioned pretreating agent is as follows：
Mosanom 100g, urea 70g, sodium carbonate 30g, bleeding agent 5g, prevent reducing agent 10g, ethylenediamine tetra-acetic acid 2g, water
