Nanofibers

3 Properties of Nanofibers Nanofibers exhibit special properties mainly due to extremely high surface to weight ratio compared to conventional nonwovens Low density large surface area to mass high pore volume and tight pore size make the nanofiber nonwoven appropriate for a

In a US patent entitled 'composite nonwoven fabrics' Gessner and Trimble (1998) described a composite nonwoven fabric prepared by laminating two oxidatively degraded spunbond nonwoven webs of thermoplastic filaments to a meltblown web of microfibres thus forming a spunbond/meltblown/spunbond composite nonwoven fabric for numerous applications including

Adsorptive nonwoven substrates are composite media that contain adsorbent materials within their fibrous structure the methods to incorporate adsorbents in nonwoven webs determine their adsorption capacity The key objective for hybridization is to immobilize the adsorbent while controlling the packing density and pressure drop of the composite media

Attempts have been made to produce a nonwoven fabric having the appearance of terry cloth For example U S Pat No 4 465 726 and U S Pat No 4 379 799 both to Holmes et al describe an apertured ribbed terry cloth-like nonwoven fabric produced by fluid entangling of fibers on a special forming belt Even if apertures could be avoided in

The formed web (usually air-laid or wet-laid but someti mes spun bond or melt-blown etc ) is first compacted and prewetted to eliminate air pockets and then water-needled The water pressure generally increases from th e first to the last injectors Pressure s as high as 2200 psi are used to direc t the water jets onto the web This pressure is sufficient for most nonwoven fibers although
