莲纤维的物理性能

 为了解莲纤维的基本物理性能,为莲纤维织物的开发提供理论参考,对莲纤维的密度、线密度和回潮率等基本物理性能进行测试。研究表明:莲纤维的密度为1.1848 g/cm3,远比棉、苎麻及羊毛的密度小,与蚕丝、腈纶接近;莲纤维的线密度为1.55 dtex,远小于苎麻、蚕丝,与棉纤维及棉型化纤的线密度较接近,说明莲纤维较细,有利于成纱强力和条干均匀度,可纺高支纱;莲纤维回潮率为12.32%,比棉、蚕丝高,比羊毛、粘胶要低,与苎麻接近,说明莲纤维具有很好的吸湿性。

Physical property of lotus fibers

To understand the fundamental physical properties of lotus fiber and provide the theoretical basis for developing lotus fiber fabric,this paper tested the fundamental physical properties of lotus fiber such as density,linear density and moisture regain.The results show that the density of lotus fiber is(1.184 8) g/cm~3,much less than that of cotton,ramie and wool fibers,but similar to that of silk and acrylic.The linear density of lotus fiber is 1.55 dtex,finer than ramie and silk fibers,and similar to cotton and cotton type chemical fibers.It indicates that the lotus fiber is very fine and is beneficial to resultant yarn strength and yarn evenness.It can spin high count yarns.The moisture regain of lotus fiber is 12.32%,larger than that of cotton and silk,and less than that of wool and viscose,but similar to that of ramie fiber.It shows that the lotus fiber has very good absorbent quality.
