摘　　要：在黄牛沙发革的制造过程中,集成采用低硫低灰、保毛脱毛、无氨脱灰和少盐浸酸清洁准备工段技术。选择改性栲胶、改性戊二醛、合成鞣剂等无铬鞣剂进行复合结合鞣。结果表明,沙发革产品收缩温度达到94.5℃,耐拉伸和抗撕裂性能较好。革身丰满、柔软、有弹性,粒纹均匀一致,光泽自然。The cleaning technologies were used in producing the cattle upholstery leather, such as liming in low-lime and low-sulfide, hair saving unhairing, deliming without ammonium salt, soaking in low-sah etc. Several chrome free tannig agents such as modified vegetable tannin, modified glutaraldehyde and syntans were combined and applied in the tanning process to obtain high shrinkage temperature and high mechanical properties. It shows that Ts is 94.5℃. The resultant leather is plumpy and soft with good resilient, tensile and tearing resistance, and the surface grain is uniform and natural.
