摘要
为了提高纳米复合口罩的过滤性能,采用静电纺丝技术,以丝胶蛋白、聚环氧乙烷为原料制备丝胶纳米复合口罩用料;设计四因素三水平正交试验,分析纳米复合口罩的过滤性能影响因素。结果表明:纺丝时间是影响纳米复合口罩过滤效率与吸气阻力的最重要因素,平均纤维直径的影响次之,而无纺布层数和无纺布克重对其影响较小。当纳米复合口罩制备工艺参数为纺丝时间10h,平均纤维直径472nm,无纺布克重20g/m2,无纺布层数为2层时,口罩的过滤效果好。
In order to improve the filtration performance of nano-composite masks,silk sericin and polyethylene oxide were used as materials to prepare sericin nano-composite masks using electrostatic spinning technology.Four factors and three levels of orthogonal test were designed to analyze the factors influencing the filtration performance of the nano-composite mask.The results showed that the spinning time was the most important factor affecting the filtration efficiency and suction resistance of the nano-composite mask,followed by the average fiber diameter,and the non-woven layer number and non-woven weight had little influence on it.When the processing parameters of the nano-composite mask were spinning time of 10 h,the average fiber diameter was 472 nm,the weight of non-woven was 20 g/ m^2,and the number of non-woven layers was 2,the filtration effect of the mask was good.
