Abstract: The regenerated leather (RL) was prepared by hot-pressing method. During the processing, the abandoned cow leather shavings after chrome tanning were used as raw materials, the natural high ammonia latex 60% DRC(HA) was used as adhesive, and the effects of material ratio and hot-pressing conditions on the surface wettability and water absorption of RL were studied. It found: The contact angle of RL（90°-150°）had little correlation with the sizing amount, had a linear positive correlation with the water consumption, a positive correlation with the hot-pressing temperature and pressure, and a significant negative correlation with the hot-pressing time, the RL was a hydrophobic material with low surface wettability.

Key words: hot-pressing conditions, natural rubber latex, regenerated leather, dry-processed, contact angle, water absorption
