POLYPHENYLENE SULFIDE MICROFIBRES

摘要

Fibres, nonwovens or loose heaps of fibres consisting of polyphenylene sulphide (PPS) or of mixtures of PPS with other polymers are produced by a melt spinning process, in which the melt filaments are drawn through a gaseous medium flowing essentially parallel thereto at the speed of sound or supersonic speed and are cooled below the melt temperature, amorphous fine or very fine fibres (17) of infinite length being formed by simultaneous deformation and cooling, which fibres are laid to form a nonwoven or loose heap of fibres. ……
