摘　　要：油蜡变色效应是一类有变色特性的油和蜡施于革面,成革在外力(拉力、顶伸、弯曲、折叠)作用下革面对光的吸收、折射差别表现出颜色深浅不一的效果,外力解除后粒面颜色又自然恢复。油蜡变色革要求革坯粒面紧实、平细,只有达到这种要求变色效果才明显。影响油蜡变色效果的关键就是革坯对油蜡的固定和油蜡的渗透深度。本文主要介绍了松软、有泡沫感的黄牛油蜡变色沙发革的制造技术。Leathers are coated by the characteristic oils and waxes, and then the finished leathers are effected by the external forces （i. e. pulling forces, stretches, bendings, foldings and so on） . As a result, the colors of the leathers may be different in depth, due to the various absorption and reflection of the leather surface to the sunlight. The grain color recovers to the original one if the outside forces disappear. That is the pullup effect. Oil-wax pulluped leather depends on the solid and fine grains of the crust. The effects on the oil-wax pullup are the oil and wax fixation and penetration depth. The preparation of the oil-wax pulluped cattlehide sofa leathers with softness and sponge feelings are introduced in this paper.
