New functional binder for leather material by using biodegradable polymers having bondability and antibacterial activity

研究了具有粘接性的PVA和具有抗菌效果的壳聚糖可生物降解的聚合物共混液作为皮革粘合剂的用途，通过耐屈曲试验发现，皮革表面的等离子体处理可以起到防止脱漆剂的作用。虽然皮革很容易发霉，但有研究表明，在皮革表面涂抹混合溶液可以减少霉菌的生长。此外，壳聚糖与PVA的混合具有较好的抗菌性能。结果表明，PVA与壳聚糖的最佳共混比例为6：4，能满足各项性能要求。可望通过PVA/壳聚糖共混液的可生物降解聚合物共混液来预防皮革材料的问题。

This study was investigated usefulness as the binder for leather by using biodegradable polymer blend solution of PVA with adhesive property and chitosan with antibacterial efficacy.It was found that plasma treatment on surface of the leather was useful as the effect of the binder to prevent the paint remover by testing flexing endurance. While the leather is easy to get moldy, it was revealed to reduce the growth of mold in the leather by coating the blend solution on the surface. Further, antibacterial property was effective by the admixture of chitosan into PVA. As a result, the most effective blend ratio of PVA and chitosan was 6 to 4 which can satisfy all properties. it was expected to prevent the problem about leather material by using biodegradable polymer blend solution of the PVA/chitosan blend solution.
