Classification of leather wounds

Leather wounds are generally divided into natural leather wounds and leather late wounds. Leather injuries due to the way the animals are raised, the season of slaughter, the place of origin, and improper processing are called natural injuries. Here we only focus on repairing the wounds in the later stage of leather, that is, the wounds caused by the use of leather goods.

Classification of leather repair paint

According to the shape, it can be divided into liquid repair paint and paste repair paint. It is common to see the claims of anions and cations in repair paints. The nuclei in the material are negatively charged when they get electrons, and positive when they lose electrons, and the repair effect is completed under the action of the force between the molecules. The distinction between anions and cations is mostly used in the spraying of the tanning process, and is related to its filling performance and firmness. Others are non-ionic, full-grain type.
