Filaments and fibers having discontinuous cavities |
摘要 |
A filament of a thermoplastic synthetic polymer having a plurality of adjacent, separate discontinuous cavities is made by a process wherein a silicone oil and an inert gas or gas-forming substance are dispersed in a polymer melt, and the melt is extruded into a filament. The melt contains up to and including 1% by weight of the silicone oil, based on the weight of the melt, at the time it is extruded and up to and including 10% by weight of an inert gas.
