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

本研究将具有粘接性的PVA和具有抗菌性的壳聚糖的生物降解性高分子混合溶液作为皮革用粘合剂，通过耐折性试验，发现皮革表面的等离子体处理作为粘合剂的防脱漆剂效果是有效的。 虽然皮革容易发霉，但通过将共混溶液涂覆在皮革表面上，可以减少皮革中霉菌的生长。 此外，壳聚糖与聚乙烯醇的混合物的抗菌性能是有效的。 结果表明，聚乙烯醇与壳聚糖的最佳共混比为6：4，可满足各种性能的要求。 预期通过使用PVA/壳聚糖共混溶液的可生物降解聚合物共混溶液来防止皮革材料的问题。

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.
