壳聚糖在皮革中的应用初探

Application of Chitosan in Leather Making Process

在皮革生产的湿加工中,向皮革胶原纤维上引入具有生物活性的壳聚糖分子,并分析了壳聚糖用量的变化、抗菌处理时间的变化、抗菌处理pH值的变化以及抗菌处理温度的变化等因素,对皮革物理性能和抗菌性能的影响.结果表明：壳聚糖与皮革纤维作用的合适条件为,壳聚糖用量为皮质量的0.45%,pH值控制在2.8～3.0,作用温度可选60℃,作用时间可取60～90min;

An active molecule- chitosan was introduced into the leather making process. The following factors that influence the physical and antibacterial properties of leather were analyzed： quantities of the chitosan, time of the antibacterial treatment, pH values and temperatures of antibacterial treatment. It shows that the optimal conditions for chitosan and leather are as follows： the quantity of chitosan is 0.45% （leather weight）, pH value is between 2.8-3.0, temperature is 60℃ and treatment time is 60 - 90min.
