Abstract

The invention discloses a sheep shoe upper leather manufacturing process which particularly and sequentially comprises the steps of soaking, fleshing, lime wrapping, depilating, liming, deliming, softening, souring, tanning, blue pelt lot grouping, wringing, shaving, retanning and dyeing, secondary wringing, vacuuming, hanging and airing, vibration softening, stretching, toggling, deburring, leather fluffing and finishing. The process provided by the invention is properly selected, since the retanning and dyeing procedure plays an important role in manufacturing sheep leather, through improvement of the procedures, leather quality is improved obviously, the growth lines and the back-ridged lines of rawhide are completely opened, grain sides are flat and fine, and the yield of leather is increased; the location difference of a leather body is reduced, the fullness of the entire leather is improved, the leather body can be moistened, the production cost is lowered, and the leather is enabled to be natural and environment-friendly.
