Background
The water consumption of the leather industry is large, wherein the water consumption of a wet dyeing and finishing section (from blue wet leather processing to crust leather) is about 1/3-1/2 of the total water consumption. Taking cow leather as an example, 45-60m3 of water is needed for processing each ton of raw leather to finished leather, 40-55m3 of waste liquid is discharged, wherein the water consumption of a wet dyeing and finishing section is about 15-25m3/t, and the water consumption and the water discharge of the waste liquid are about 13-23m 3/t. In the previous research, attempts to prepare blue wet leather by using seawater instead of industrial water have been successful, but unfortunately, simply pretreated seawater cannot be used for wet dyeing and finishing, which can seriously affect the quality of the dyeing and finishing process and the quality of the product, and probably because of the complex seawater components and the partial components of the wet dyeing and finishing chemicals. The simple filtration treatment can not meet the water requirement of the wet dyeing and finishing process, and the treatment cost is too high after the membrane treatment. Therefore, seawater needs to be studied for proper pretreatment.
