【摘要】 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;更多还原

【Abstract】 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.更多还原
