PROCESS FOR THE PRODUCTION OF STAPLE FIBERS

摘要

Staple fibers are produced continuously and rapidly from a thermoplastic material by spinning and drawing filaments from the thermoplastic material, projecting the spun filaments at high speeds onto a lay-down receiver partly disposed over a vacuum zone so that ropy fiber aggregates are laid down on the receiver outside the vacuum zone and a random web is formed on the receiver above the vacuum zone, consolidating the resulting non-uniform web, twisting it into a strand and cutting the strand into staple fibers.
