The characteristics of the chrome-tanned sheep skin treated by radiation-induced graft of BA is presented.

Using the method of radiation-induced graft of BA instead of the chrome-retanning

the leather has been obviously improved not only in the surface

such as the brightness

fullness

uniformity of the thickness but also in the physical characteristics such as retaining of tensile strength

decreasing of water absorption after being immersed in water for 2h

and 24h

enhancement of tearing strength and stitch tear strength. Although the air permeability and water vapor permeability are a bit worse than the control

however is still in the range of the standard issued by Light Industry Ministry of our country.
