Uneven twist of double-twisted yarn often appears in the first or last few spindles of the front of the car, which is caused by the looseness and tight edges of the dragon. As for other twist unevenness.

First, check whether the spindle is stuck with foreign objects.

Second, check whether the brake has accumulated flowers.

Thirty-three is to check that the ingot is jammed with flowers.

The fourth is to check whether the pneumatic brake valve is running in with the spindle.

Fifth, the twist of individual spindles is uneven due to damage to the tension wheel and other reasons.

The following points should be noticed when reducing the twist unevenness of the double twister:

1. Make sure the tension of the belt is moderate

2, clear the bottom of the spindle in time

3. Replace the belt in time

4. Do a good job of monitoring the spindle speed and incorporate it into the cycle management, and repair or replace the slow spindle in time.

5. Guarantee the consistency of the quality of the bobbin and reduce the uneven twist caused by the quality of the bobbin

6. Try not to use plastic pipes. Plastic pipes have strong twist because of the low friction coefficient and asynchronous speed.

7. Clean the machine and yarn channel.
