short description:

The rewetting agent is a key auxiliary material in the wet finishing process of leather tanning. It is mainly used to replenish water to the blue wet leather or the dried leather pieces that have been left for a long time, so as to restore the leather to a soft and pliable state, allowing the fibers to regain their loose and malleable properties. This is necessary for laying a solid foundation for subsequent processes such as re-tanning, dyeing, and oiling. If the re-humidification is insufficient, it will lead to uneven absorption of the chemical materials in the subsequent processes, resulting in problems such as color spots, oil stains, and even cracking.
