Abstract
The invention discloses a tanning process for kid lamb skin and Hu sheep skin. The tanning process comprises the following steps that size measuring, skin cleaning, fleshing, first degreasing, first cleaning, acid maceration, depickling and secondary degreasing are sequentially conducted; the piece of the kid lamb skin and the piece of the Hu sheep skin are soaked into clear water and heated to 36-38 DEG C; a degreasing agent is added into the clear water for rotating the pieces of skin; two hours after the stop of rotating, the pieces of skin are taken out, and waste water is discharged into a skin cleaning water collecting tank; cleaning, acid maceration and tanning are conducted again, and then the pieces of skin are soaked into tanning collected water which has been recycled for less than a week to be heated to 33 DEG C; a grease dispersing agent, a fatting agent, an aluminum tanning agent, a chrome tanning agent, a synthetic tanning agent, an auxiliary tanning agent, sodium bicarbonate and a mildew preventive are complementally added, so that the PH value of the tanning collected water is 3.8-3.9, the pieces of skin are stored overnight and taken out, and waste water is discharged into a tanning water collecting tank; and wet grinding, rinsing, neutralizing, fat liquoring, drying and tidying are conducted. The tanning process for the kid lamb skin and the Hu sheep skin saves energy, protects the environment and lowers the manufacturing cost.
