Nanofiber technology (Chapter 3)

Figure 3.1 shows a TEM image of a PET fiber island and Nylon-6 sea produced by conjugate spinning and flow-drawing [1]. Chemical vapor deposition (CVD) In a CVD process, a substrate is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface. Get price

Fiber Selection for the Production of Nonwovens

2016/03/24The island in the sea fibers have excellent tensile properties, and provide good feel, softness, and bursting and tearing strength for the nonwoven fabrics. Bicomponent filaments can be used to produce a bonded fabric, with one of the components being thermoplastic to facilitate heat bonding and the other component having properties that will enhance the quality of the final fabric [ 4 ].

Advances in Polymeric Nanofiber Manufacturing Technologies

Advances in Polymeric Nanofiber Manufacturing Technologies Nanofibers continue to be one of the major success stories of nanotechnology . Whereas the definition of nanofibers according to National Science Foundation is that the diameters have to be less than 100nm, in the textile trade, fibers less than one micron in diameter are treated as nanofibers.

Meltblown submicron fibers for filter media and other

2015/04/01Typical melt blown webs will have fibers in the range of 2-5 microns on the average with a wide distribution in diameter. Because of the type of the polymer used and the process, the fibers are not necessarily strong, but the fabrics have good barrier properties and serve as ideal materials for filter media. Meltblown webs are extensively used Get price

Fibers

Electrospinning, for the last few decades, has been extensively acknowledged for its ability to manufacture a macro/nanofibrous architecture from biopolymers, which is otherwise difficult to obtain, in a cost effective and user-friendly technique. Such biopolymer nanofibers can be tailored to meet applications such as drug delivery, tissue engineering, filtration, fuel cell, and food packaging Get price
