How to solve the large uneven twist on the two-for-one twister?
Uneven twist of two-for-one twisted yarn tends to appear in the first few spindles or the latter few spindles of the car head.
One is to check whether there is any foreign matter on the spindle,
The second is to check whether the brake has accumulated flower loops,
The third is to check that there are flowers on the spindle,
Fourth is to check whether the pneumatic brake valve is running in with the spindle wheel,
Fifth, the tension wheel is damaged and does not work, causing the uneven twist of individual spindles.
To reduce the uneven twist of the two-for-one twister, you should pay attention to the following points:
1. Ensure that the tension of the dragon belt is moderate
2, clear the accumulated flowers at the bottom of the spindle in time
3, the dragon belt should be replaced in time after it is worn out
4. Do a good job of monitoring the spindle speed and include it in cycle management, and repair or replace slow spindles in time
5. Ensure the consistency of the bobbin quality and reduce the uneven twist caused by the quality of the bobbin
6. Try not to use plastic pipes as much as possible, because plastic pipes have a small friction coefficient and the speed is not synchronized, they form strong twists.
7. Clean the machine table and yarn passage.
