COMPACT YARN

The process

Compact spinning is designed to reduce hairiness in yarn. In traditional spinning fibers in the selvedge of strand emerging from front roller nip do not get fully integrated into yarn because of restriction to twist flow by the spinning triangle. These fibers therefore show up partly as protruding hairs or wild fibers. To overcome this effect, the spinning triangle is nearly eliminated in compact spinning by incorporating a condensing zone after main drafting zone. The condensing zone has a revolving perforated apron with suction underneath. The fibers are collected on the perforated track and thus get condensed. The width of strand under front roller nip is substantially reduced and this enables twist to flow right up to nip

Eliminating the spinning triangle at the delivery section of the front roller produces quality yarn with low hairiness and high evenness.
