蛋白酶及其在羊毛处理中的作用

根据蛋白酶对羊毛纤维的作用机理，采用合适的酶和工艺对羊毛进行酶处理．蛋白酶对羊毛处理可以起到提高织物防毡缩、抗起毛起球、降低染色温度、提高织物光泽和细化纤维直径等作用，大大提高羊毛纤维及其织物的品质．

蛋白酶及其在羊毛处理中的作用

80年代，由于氯化一树脂两步法羊毛处理工艺废水中存在大量的可吸收有机卤化物AOX类物质(Absorbable organic Halogen)会残留在纤维中，对环境污染大，对人类身体也有害，随着环境问题愈加为人们重视，用酶进行羊毛织物防毡缩整理成为研究重点。

TiO_2/Polyester Non-woven Fabrics as a Kind of Photocatalyst for the Degradation of Formaldehyde Gas

The feasibility of photocatalytic degradation of the formaldehyde gas by titanium dioxide （TiO2）/polyester non-woven fabrics was studied. Tbe effects of parameters such as tbe concentration of TiO2 solution, pH value, and drying temperature on the photocatalytic degradation of the formaldehyde gas were also studied. The results showed that the photodegradation efficiency of the formaldehyde gas increased rapidly with the increasing of the concentration of TiO2 solution up to 15g/L, but when the concentration was in excess of 15g/L, the photodegradation efficiency decreased gradually and fluctuated due to light obstruction and disperse state of TiO2. Adjusting the pH value in the solution, the efficiency of photocatalytic degradation of the formaldehyde gas could be improved. The mechanisms of the reaction and the role of the additives were also investigated. After 42hours, TiO2/ polyester non-woven fabric showed no significant loss of the photocatalytic activity.
