Twist Insertion
The new spinning systems clearly avoid the limitations produced by the twist insertion mechanism. It is possible to increase the twist insertion rate
and the yarn production speed quite considerable. This increase is shown in the following:
| Spinning System | Actual twist inserting rate (rpm) | The system is limited by | |
|---|---|---|---|
| Twist insertion rate | Doffing & transport | ||
| Ring | 15,000-24,000 | Yes | No |
| Wrap | 25,000-35,000 | Yes | No |
| Rotor | 80,000-1,50,000 | Yes | Partly |
| Air-Jet | 1,50,000-2,50,000 | No | Yes |
| Friction | 2,00,000-3,00,000 | No | Yes |
