The invention discloses anti-bending leather. The anti-bending leather comprises the following leather
processing technology steps that 1, a
preparation stage is carried out, specifically, soft
skin materials are carefully selected, impurities are removed, and
degreasing,
softening and
pickling are carried out; and 2, a tanning stage is carried out, specifically, the structure of the leather is changed through a chemical method, wherein the main procedures comprise pre-tanning, main tanning and retanning. According to the anti-bending leather, multiple soaking and
impurity removal are adoptedin the
preparation stage, so that the permeability of pores of the leather is conveniently improved, and the smoothness of the inner surfaces of the pores is improved; the leather is repeatedly processed through multiple
layers of pre-tanning, main tanning and retanning, and collagenous fibers of
animal skin are changed in structure through the chemical method, so that the
animal skin is changed into the leather from the
skin, the softness of the leather is improved, the fullness is improved, the part difference is reduced, the
surface charge of the leather is changed, and the
dyeing uniformity and adhesion performance are promoted; and through adding of
sodium bicarbonate, resin and
tannin extract and scientific proportion of the multiple materials, the surface of the leather is more delicate in touch, oily,
antioxidant and better in bending-resistant effect.
