Calcium formate, as a white crystalline powder tanning material, has shown its unique advantages and important role in the field of leather manufacturing. It not only improves the softness, durability and dyeing fastness of leather, but also promotes the development of the leather industry in a more environmentally friendly direction.
Application of calcium formate in leather tanning
In the process of leather release, calcium formate, as an excellent tanning preparation, can react with collagen in leather to form a stable cross-linked structure. This kind of structure not only enhances the strength and elasticity of leather, but also significantly improves its wear resistance and water resistance. Compared with the traditional chromium tanning, vegetable tanning, protein tanning and other methods, calcium formate tanning has a faster reaction rate and better tanning effect. It can complete the tanning process in a relatively short time, while reducing the damage to the leather fiber, maintaining the natural texture and softness of the leather
In addition, calcium formate can also be used as a dyeing aid, play an important role in the leather dyeing process, it can improve the penetration and binding force of the dye, so that the dye is more evenly distributed on the leather surface and inside, thereby enhancing the leather dyeing medium and color brightness, this feature makes calcium formate in the production of colored leather and special effect leather is particularly important.
Second, the environmental advantages of calcium formate
With the enhancement of environmental awareness, the emission of harmful substances in traditional tanning methods has attracted increasing attention. As an environmentally friendly tanning material, calcium formate has the advantage that it has no emission of harmful substances. During the tanning process, calcium formate will not produce waste water and waste gas harmful to the environment, thus reducing the pollution to the environment. This feature not only meets the requirements of modern industrial green production, but also meets the needs of consumers for environmentally friendly products.
In addition, calcium formate also has good biodegradability, and even a small amount of wastewater generated during use can be rapidly decomposed in the natural environment without long-term impact on the ecosystem. This environmental advantage makes the application prospect of calcium formate in leather industry more broad.
Third, the effect of calcium formate on product quality
The application of calcium formate in leather tanning not only improves the physical properties of leather, but also significantly improves the touch and appearance of leather, and the surface of the leather after calcium formate tanning is more delicate, soft and elastic. At the same time, calcium formate can also reduce the moisture content of the leather surface, make the leather more durable, these advantages make calcium formate tanned leather in clothing, footwear, furniture and other fields have been widely used.
In addition, calcium formate tanned leather also has good air permeability and moisture absorption, can keep the skin dry and comfortable, reduce bacterial growth. This feature is of great significance for improving the comfort and service life of leather products.
To sum up, calcium formate plays an important role in leather tanning, it not only improves the physical properties and dyeing degree of leather, but also promotes the leather industry to develop in a more environmentally friendly direction, with the continuous progress of technology and the enhancement of environmental awareness, calcium formate in the leather industry application prospects are broader, the future, We have reason to believe that calcium formate will become one of the important forces in the field of leather tanning and make greater contributions to the sustainable development of the leather industry.
