Fiber Society 2012 Spring Conference: Fiber Research for Tomorrow's Applications | Year: 2012

Besides considerable progress in the direct web spinning processes (melt blown, electrostatic spinning centrifuge spinning) to produce nonwoven materials with finest fibers, success has been reached as well in the formation of filament yarns and staple fibers close to the submicrometer range. The centrifuge spinning reached the production process level and actually developments are ongoing for applications in technical fields (filtration, isolation, battery separators etc) and in medical technology. The melt blow technology is going down to 0,2 μm but still in laboratory scale. The filament and staple fiber spinning yet is still bound to the 1 μm range. The bicomponent technology is needed here and a matrix has to be dissolved or the fibers are to split. The challenges are to do this environmental friendly as well as to allow processing on standard textile machinery. The presentation will show the newest developments at the ITV with regard to the special features and the still existing technical limitations.
