A novel macroano nonwoven with environment-friendly properties: The effect of air gap

摘要

@@Ramie web, which is made from a kind of natural cellular fiber-ramie, is of high air and moisture permeability, antibacterial ability. However, because of the high crystallinity and high degree of orientation of ramie fibers, it has some undesirable properties such as poor elasticity, bad wrinkle recovery and harsh handle [1], which hinders its application as underwear clothing, face mask and wound dressing. In the previous work, we successfully prepared a macroano nonwoven with better physical properties than pure ramie web by electrospining polyurethane (PU) into nanofibers and covering over the surface of ramie webs [2]. In the present work, the effect of air gap between nozzle and target during electrospinning was investigated in detail to figure out its influence on the morphology and tensile property of resultant nonwovens.
