6. Spinning mill (heart of the company)
The resulting end product has the following breathtaking parameters:
Thick yarn: 8m / 1g
Fine yarn: 120m / 1g
Finest yarn: 300m / 1g
This is where the actual spinning of the prepared fibers (roving) takes place. We have ring spinning machines with long staple drafting systems for this purpose. The attached roving is drawn and twisted in the drafting system so that a fine and stable thread is created.
Since we produce yarns with a count of Nm 2 (= 2 m / 1g) to Nm 300 (= 300 m / 1g), different types of machines are in use.
The spinning machines are fully automated. The full spinning corps are placed on a waiting carriage by means of a conveyor belt and empty spinning corps are placed on the machine.
For our finest yarn, the roving is spun into a fine silk thread with a delay of 50 times and over 950 twists per meter. The newest machine will be integrated in October 2021 after new installations in 2006, 2007 and 2009. The oldest spinning machines are over 50 years old. Additional equipment makes it possible to produce fancy yarns (with thick and thin places) or core yarns with Lycra threads as the core.
7. Winding
The finished yarn is rewound here.
The yarn has a length of 300 KM / 1 Kg
A quality check is carried out using sensors.
Nm deviations and foreign fibers are recorded and automatically cut out depending on the programmed cleaning level. The yarn is then put back together again by splicing (knot-free).
This process guarantees the highest yarn quality in order to meet the high quality demands of our customers.
8. Twisting
Most of the single yarns from the spinning mill are twisted in the next step.
Two to three threads are twisted together here
After the thread has received the direction of rotation Z during spinning, the two threads together get an S twist. A twist gives the yarn increased tear and abrasion resistance. In the area of thinner yarns, we work with the two-stage twisting process. First the threads are pinned (= wound together) and twisted slightly (= pre-twisted).
Only in the second stage is the correct speed per meter twisted (= twisting out).
For thinner yarns, this process runs in two stages on two machines.
