| Sumario: | This paper studies the application of two isoprene resins, TANEX LF and TANEX LW, in leather tanning. Systematic experiments, the effects of TANEX LF and TANEX LW in the tanning process were analyzed, including their improvements in leather tensile strength, tear strength, waterproof properties and appearance. This study focused on several specific objectives. First, the effect of different pH on leather before tanning was tested. The effect of different pH of resin on the shrinkage temperature during the tanning process was tested. Second, the effect of different concentrations of resin on the shrinkage temperature during the tanning process was tested. Then, the time of resin addition during the tanning process was changed. The results show that isoprene resin shows significant effects in improving the strength and elasticity of leather, but there are certain differences in specific properties. TANEX LF excels in enhancing the strength of leather and is particularly suitable for leather products that require high durability. On the other hand, TANEX LW significantly improves the waterproof properties of leather, making it better in moisture resistance and weather resistance. Taking all factors into consideration, both tanning agents show unique advantages in different application scenarios. This paper also explores the applicability of the two tanning agents under different process parameters and proposes suggestions for optimizing the tanning process. The research results provide important theoretical basis and practical guidance for the leather industry to select suitable tanning agents, and promote the development of green leather tanning technology. |
