[0002] When dyeing wool and leather products, due to the different fiber structures of the wool quilt and the leather board, the coloring sequence and coloring ability are different, it is necessary to dye the wool color at high temperature and then dye the board color at low temperature, and blackboard light-colored wool products are very easy to cause dyeing. Effect of board dye on the wool cover to change the color of the wool surface
The traditional blackboard light-colored wool drum dyeing technology consumes a lot of water, the cost of dyeing wastewater treatment is high, and the process is difficult to control, especially in summer when the temperature is high, the water temperature in the drum when dyeing boards is difficult due to mechanical effects and external environmenta...

Embodiment 1
[0030] The finishing process of black board light-colored wool leather products includes the following specific operations:
[0033] Penetrant Metoxi: 400 parts by weight, penetrating leveling agent 0240: 600 parts by weight, dye water 5915: 150 parts by weight, ultrafine pigment paste 5450: 100 parts by weight, BASF black dye water: 150 parts by weight;
[0034] Prepare the above chemical materials into a solution, roll the 24L roll of the roller coater, roll once, and roll the 32L roll, roll 3 times;
[0035] 3) Drying: Each roll needs to be dried once, the drying temperature is 50-70°C, and the board is placed on the board;
[0036] 4) Water spray: spray water from the water spray machine, drain water 2 times, and let it stand for 30 minutes;
[0039] 7) Polishing: make the surface pile uniform, and...
Embodiment 2
[0057] The difference with Example 1 is: the chemical material that roll coating adopts comprises the following components by weight: 300 parts of penetrating agent Metoxi, 700 parts of penetrating and leveling agent 0240, 100 parts of dye water 5915, superfine particle pigment 80 parts of paste 5450, 200 parts of BASF black dye water.
Embodiment 3

Abstract
The invention belongs to the technical field of processing of leather products and discloses a black plate light-colored fur leather product coating process. The process comprises pre-coating, finishing of semi-finished products, post-coating and finishing of finished products. Pre-coating includes horizontal toggling, roller coating, drying, water spraying and cage rotating; finishing of the semi-finished products includes staking and polishing; post-coating includes vertical toggling, bottom covering, spraying of a bottoming coat, one-time ironing, spraying of a surface coat and ironing of the finished products; finishing of the finished products includes fur ironing, fur shearing, brushing of a fur ironing agent, ironing of the finished products and warehousing of the finished products.A roll coating material includes, by weight, 200-500 parts of a penetrating agent Metoxi, 500-800 parts of a penetration leveling agent 0240, 100-200 parts of dye water 5915, 80-120 parts of ultrafine pigment paste 5450 and 100-200 parts of BASF black dye water, wherein the total use amount of the dye water 5915 and the BASF black dye water is 280-300 parts. The process reduces the discharge of dyeing wastewater and saves water and chemicals, and the production is safer and more environmentally friendly.
