Application of Compound Formaldehyde Scavenger in Leather


Article Preview

Different types of formaldehyde scavenger were used to remove free formaldehyde in aldehyde tanning leather. The results showed that: the formaldehyde removal effect of self-made aminated collagen (EAC) was the best, followed by hyperbranched polymer with active methylene (HPAM). Then the mixture of EAC and HPAM was used to remove free formaldehyde. The optimum conditions were obtained by single factor experiment. The weight ratio of EAC and HPAM was 1:1 and the processing time was 2h. Finally, EAC, the mixture of EAC with HPAM and chitosan were used to remove free formaldehyde in oxazolidine tanned sheep skin. The comparison results showed that the formaldehyde-removal rate of the mixture of EAC and HPAM reached to 75% which was better than that of EAC and chitosan, but also it had obvious thickening and assisting dyeing effects to leather.
