摘要: 为了完好地保留蚕丝上的丝胶,扩大蚕丝的应用领域,文章通过改变蚕吐丝结茧的习性,引导180只成熟桑蚕在表面光滑的方形PVC平板(66 cm×220 cm)上进行吐丝,得到一款轻薄且均匀的蚕丝膜材。该蚕丝膜材呈半透明状,厚度为0.18 mm,平方米质量为38 g/m2,扫描电镜下膜材上的蚕丝形态呈现出规则的交叉分层叠放,孔隙分布均匀,孔隙率为83.76%。通过一系列的实验,对蚕丝膜材的干湿强力、伸长、透气、抗菌等性能进行测试。实验结果显示,该膜材在干态下的强力大于湿态,干态下的断裂伸长小于湿态伸长,各部分透气均匀,对大肠杆菌和枯草芽孢杆菌均具有一定的抗菌性。

Abstract: To well preserve the sericin of silk and expand the application field of silk, 180 mature silkworms were put on a smooth square PVC plate(66 cm×220 cm) for spinning through changing the habit of silkworms spinning silk and cocooning. Then, a thin and light silk membrane of uniform thickness was obtained. The silk membrane was semi-transparent with the thickness of 0.18 mm and the weight of 38 g/m2. Under the scanning electron microscope, the silk showed regular cross stratification stacking on the silk membrane. The pores of the silk membrane were well distributed, with the porosity of 83.76%. Through a series of experiments, the dry and wet strength, elongation, air permeability and antibacterial properties of silk membranes were tested. Experimental results revealed that the dry strength of the silk membrane was stronger than the wet strength, and the elongation at break in dry state was less than that in wet state. The air permeability of each part was uniform, and the silk membrane had certain antibacterial properties against Escherichia coli and Bacillus subtilis.
