Abstract

A process for producing a bale of crimped staple fibers includes the repeated steps of cutting continuous filament crimped nylon tow into segments, maintaining the integrity of the segments while tramping charges of the segments under pressure to form a compacted layer, holding the layer to retain layer compaction and then pressing the layers and strapping the pressed layers.
