Nanofibre Potential

Spunmelt electret nonwovens (formed in the association of spunbond and meltblown processes with electrostatic field) are commonly employed for such filters as they offer good filtration efficiency with low energy losses The meltblown process gives very fine fibres from 500 nm to 8 m but with lognormal fibre diameter distribution (Bresee et al 2006) This leads to a completely

Handbook of nonwovens

Fibre type 17 18 Handbook of nonwovens such as polyester have evolved to improve compatibility with high-speed nonwoven carding systems The applied forces in carding give rise to fibre breakage and permanent fibre elongation which modifies the original fibre length distribution and in some low-temperature materials such as PVC may be subject to thermal shrinkage during the process Whilst

Technology of nanofibres: An overview

Another possible approach to the use of bicomponent fibre spinning to manufacture nanofibres is to make splittable fibres in melt spinning process [27 28] The number of segments would need to be sixteen or greater and the best approach might be to use a water dissolvable polymer in a small ratio along with PET or PP (Figure 4) The ultimate approach is to melt blown INS fibres that contain
