SPINNING PROCESS FOR THE PRODUCTION OF SYNTHETIC CONTINUOUS FILAMENT YARNS

摘要

The present invention relates to a spinning process for the production of synthetic continuous filament yarns that can be used in the continuous filament production industry. Suitable polymers are those that are melt-spun, such as, inter alia, polyesters, polyamides and polyolefins. The spinning process comprises two filtration steps: a first step corresponding to a prefiltration employing one or more centralized filters located at a point on the polymer melt transfer lines and a final filtration carried out in the filtering elements of the screen-pack/spinneret assemblies.
