纺织基雾中集水装置的研究与制作

The Research and Preparation of Textile Fog Water Collecting Device

为缓解水资源短缺的困境,寻找可能存在的淡水获取方式,将甲虫背部表面特性及蜘蛛丝的吸水机制与纺织技术相结合,采用织造技术制备纺织基雾中集水装置(集水帆),并且对其进行优化改进,得到最优化的雾中集水装置。通过测试得知:集水量随亲水面积比例的减小先增大后减小,当亲水面积比例为4∶20时集水量最大;相同比例下具有四角菱形亲水区域的集水帆集水效果好于圆形集水帆;随着集水帆平面倾斜角度的增大,集水量逐渐增大,当集水帆平面角度为90°时达到最大;长丝集水帆的集水效果优于短纤纱集水帆的集水效果。

To alleviate the water shortage dilemma and look for a fresh water obtaining method,the characteristics of the back surface of the beetle Stenocara,the water absorption mechanism of the spider silk and the textile technology were combined to prepare the textile fog water collecting device by weaving technology,and the optimization device was done.The results showed that the water collecting capability increased at first then decreased with the decrease of the hydrophilic area ratio,and the best proportion was the ratio 4 ∶ 20.Under the same proportion,the collecting effect of the sails of hydrophilic area with four angle diamond shape was better than that of the circular shape,and the water collection increased gradually with the increase of the inclination angle of the sail,when the angle of the catchment is 90＆#176;,the best collecting effect was achieved.At the same time,the water collecting effect of filament yarn sails was better than that of staple yarn.
