Melt-Electrospinning of Polypropylene/Poly(ethylene-co-vinyl alcohol) Core/sheath Composite Fibers
Polypropylene Poly (ethylene-co-vinyl alcohol) Melt-electrospinning Laser melting
2009/4/13
Rodlike samples were made from Polypropylene (PP)/Poly(ethylene-co-vinyl alcohol) (EVOH) core/sheath composite fibers. From these rodlike samples, ultra thin fibers were produced using a melt-electr...
Approximate Study on Tensile Model of Wool/spandex Core-spun Yarn
core-spun yarn spandex specific stress stress-strain curve tensile strength
2009/2/16
An approximate approach is presented to calculate and predict the specific stress of wool/spandex core-spun yarn, based on an idealised yarn structure model and Hearle’s yarn theory. The approximate m...
