Nanofibers by conjugated spinning

Abstract

Historically, conjugated spinning technology was proposed more than 50 years ago. Recently, this technology has enabled the production of nanofibers. Using this technology it is possible to produce uniform nanofibers in a filament shape. Thus, produced nanofibers can be processed to woven fabrics and knitted works; this is not possible for other types of nanofibers such as the web-type shape made by electrospinning technology, etc. In this chapter, two types of conjugated spinning technology, i.e., blend-spinning technology and spinneret technology, are introduced. By the application of the former technology, nanofibers can be thinned to 60 nm in diameter, and by the latter technology, circular and noncircular cross-sectional nanofibers with uniform thickness can be produced.
