the mechanism and the parameters affecting the matrix-fibril morphology in melt spun polyblend fibers are discussed. the properties of polymeric blends depend considerably on their final morphologies. blending of two miscible polymers, normally gives rise to formation of a single-phase morphology while blending of two immiscible polymers can create a two or three (in case of using compatibilize...

Sm(CobalFe0.1CuxZr0.03)7 (x = 0.0–0.25) ribbons have been prepared by melt spinning. The effects of annealing parameters on coercivity and its temperature dependence have been studied systematically. It is found that the melt-spinning technique remarkably improves the magnetic properties and simplifies the annealing process. The high-performance precipitation-hardened magnets can be obtained by...

The application of melt spinning processes for the production of cellulosic fibres would be a significant sign of progress for economic and environmental reasons. A process for melt spinning of trimethyl-silycellulose (TMSC) was developed. Bis(trimethyl-)silylcarbamate (BSC) was found to be excellent for the silylation of cellulose due to good swelling and penetration into cellulose. The synthe...

The features of martensite transformation in Fe (31 32)% Ni melt-quenched alloys are considered. The meltquenching was realized by spinning technique with variable parameters. The influence of the melt-quenching on structural and kinetics transformation parameters is revealed. In particular Ms point is shown to decrease but volume percentage of athermal martensite is found to be invariable with...

Melt spinning of polypropylene nonwoven nanofiber mats is demonstrated using Forcespinning The effects of rotational speed and melt flow rate of polymer on fiber diameter were studied. It was observed that melt flow rate of the polymer plays a major role in nanofiber formation and uniformity. Differential scanning calorimetry and X-Ray Diffraction analysis indicate that the crystallinity of nan...
