The developments in spinning systems from mule
spinning, cap spinning, flyer spinning and then ring spinning to the
today's latest spinning systems like
rotor spinning, airjet spinning shows an ultimate ways to produce yarn. However, the versatility of ring
spinning has created its own root in todays
spinning world. The compact spinning is one
of the major developments in the history of spinning, as the improved properties of compact yarn over conventional
associated with conventional ring frame:-
The width of fiber strand fed is always more than width of spinning triangle. The width of spinning triangle is depends upon spinning tension and is directly related with spinning tension. Basically, the restriction of twist flow to the front roller nip, because of spinning geometry, causes the formation of spinning triangle. The fibers at selvedge of fiber strand, delivered by front roller may not get fully integrated into yarn body or they may gets lost through pneumatic suction tube (PN waste), because in the spinning triangle, the selvedge fibers are always at very high tension than inner ones and due to improper integration of selvedge fibers into yarn, the hairiness rises up.
