The problem of non slip fabric not moving when using a sewing machine may be caused by various reasons. Below, I will provide some suggestions to help you solve this problem:

Replace suitable needles: Anti slip fabrics are usually thicker, so it may be necessary to use needles that are suitable for thicker fabrics. Try replacing with a larger needle size that is more suitable for thick fabrics and see if there is any improvement.

Adjust the thread tension of the sewing machine: Check the thread tension setting of the sewing machine to ensure it is suitable for the anti slip fabric you are using. If the thread tension is too high, it may cause the fabric to not pass through the sewing machine smoothly.

Choose the appropriate sewing machine thread: Use thread that is suitable for the material and thickness for sewing. Choosing high-quality thread can improve the sewing effect.

Adjusting the sewing speed of the sewing machine: If the speed of the sewing machine is set too fast, it may cause the anti slip fabric to be difficult to pass through the sewing machine. Reducing the sewing speed appropriately can improve the coordination between the shuttle head and the fabric.

Check the cleanliness of the sewing machine: Ensure that the sewing machine is in a clean state, especially the conveyor of the sewing machine. If there is dust or fiber blockage in the conveyor, it can also cause the fabric to not pass through properly.

Try adjusting the stitching method of the sewing machine: Depending on the characteristics of the non slip fabric, it may be necessary to try different stitching methods (such as needle step length, double needle stitching, etc.) to ensure the stitching effect.

If the above methods are ineffective, it is recommended to consult a professional. If you still cannot solve the problem after trying the above methods, it is recommended to consult a professional sewing machine repairman or sewing teacher, who may be able to help you find a more suitable solution.

I hope the above suggestions can help you solve the problem of the sewing machine not moving. If you have any other questions or need further assistance, please feel free to let me know. Wishing you a pleasant sewing experience!
