Why does uneven coating occur? And how do we resolve this issue?

As you can see from our videos, we supply high‑quality yarn with proven solutions for common yarn defects. Take uneven oil pickup for example. It is usually caused by dirty oil‑application wheels, unstable oil supply, offset yarn bundles, tension fluctuation and abnormal oil parameters. We clean equipment regularly, stabilize oil supply and process parameters, calibrate yarn guides and test oil content to ensure even oil application. Therefore, our product quality is beyond doubt. Feel free to contact us if you are interested.
