chemical used in leather industry
Chemicals used in the leather industry play a crucial role in transforming raw hides into finished leather products. These essential compounds encompass a wide range of substances, including tanning agents, dyes, finishing chemicals, and processing aids. Chrome tanning agents remain the most widely used chemicals, accounting for approximately 80% of leather production worldwide. These chemicals facilitate various processes such as soaking, liming, deliming, bating, pickling, tanning, and finishing. Modern leather processing chemicals are designed to optimize leather quality while minimizing environmental impact. They enhance leather characteristics such as softness, durability, water resistance, and color fastness. Advanced surfactants and enzymes are employed in the pre-tanning stages to ensure proper cleaning and preparation of hides. Specialized fatliquoring agents provide the necessary lubrication and flexibility to the leather fibers. Additionally, various finishing chemicals, including pigments, binders, and top coats, contribute to the final appearance and performance properties of leather products. The industry has seen significant developments in eco-friendly alternatives, including vegetable tanning agents and biodegradable processing chemicals.
