防水革特性的研究

STUDY ON THE CHARACTERISTICS OF WATERPROOF LEATHER

本文通过大量的重复试验．研究了用防水加脂剂乳液加脂的方法生产的防水革，经过水的长时间反复浸泡后，其某些物理机械性能的变化特性，并与普通革进行了对比试验。结果表明：防水处理并不损害革的物理机械性能；更重要的是，在经过水的长时间反复浸泡后，防水革物理机械性能的变化，比普通的革要小得多。

A large number of repeating tests were done to research the characteristiCS of waterproof leather produced by emultion fatliquoring with waterproof fatliquors, and control tests with ordinary leather were done also. The result showed that there was no harmness to leathers physical-mechanical properties when treating leather with waterproof fatliquors. The more important fact was that, after having been soaked repeatedly in water for a long time, the pysital-mechanical properties of waterproof leather had a much more low reduction rate than of that the ordinary leather.
