Introduction
Most sewing machines come with standard tension to suit general sewing requirements, and the tension settings will vary depending on the fabric and thread being used. Although it can be complicated to adjust, setting the tension correctly is essential to achieve the best stitching results. In this article, we’ll provide some useful tips and techniques on how to adjust tension on your Singer sewing machine for the best results.
The Purpose of Tension
The tension of the thread on the sewing machine is the adjustment of the upper thread so that it corresponds perfectly with the tension of the lower thread. It is a crucial element to achieve successful sewing. Too much thread tension will cause the fabric to pucker, too loose for machine to hold fabric and top threading will appear on the right side of the fabric.
Types of Thread
The type of thread used will affect the tension of the sewing machine. Regular sewing thread should be used on lightweight fabrics, while heavier fabrics require heavier thread such as cotton, polyester, or nylon. The thread type and weight should be selected according to the weight of the fabric that is being sewn.
Adjusting the Tension
To adjust the tension on a Singer sewing machine, first locate the tension dial. It is usually located on the needle bar assembly. Turn the tension dial until the mark on the dial lines up with the number printed on the machine. Turn the dial in a clockwise direction to increase the tension, and in a counter-clockwise direction to decrease the tension.
Test Sewing
Once the tension is adjusted, a test seam should be sewn to check the results. Change the stitch length to a longer stitch and start sewing. Make sure to check the back of the fabric. It should show an even line of stitches with no thread loops on the top or bottom. If there are thread loops, loosen or tighten the tension dial as required.
Troubleshooting
If the fabric puckers, then the tension is too tight. If it is too loose, then the tension is too loose. If the thread has started to unravel, the upper thread tension may be the problem. Try to adjust the tension until the stitch looks even and the thread remains in place.
Using Alternate Thread
For special fabrics or applications, it may be necessary to use alternate types of threads, such as metallic thread, metallic bobbins, or specialty threads. These types of threads require specific tension settings for successful results, so consult the thread manufacturer for specific recommendations.
Lower Thread Tension
The lower thread tension should be adjusted so that it is slightly looser than the upper thread. To do this, turn the lower thread tension into a slightly clockwise direction to increase the tension and counter-clockwise to decrease the tension.
Using Decorative Stitches
When using decorative stitches, it is important to check the tension of the upper thread. This is because the stitches require more tension than regular stitches. Increase the tension by turning the tension dial slightly clockwise and check the test seam again.
Using Specialty Fabrics
When working with specialty fabrics, such as velvet or organza, it is important to use the appropriate thread. It is also important to adjust the tension accordingly. To do this, adjust the tension dial until the stitches appear even and the fabric does not pucker.
Doing Repairs
If you are making repairs to a garment, sometimes you may need to adjust the tension setting of the sewing machine to get the best results. In this case, try different tension settings until the stitch is even and the fabric does not pucker or buckle.
Sewing on Thick Fabrics
When sewing on thick fabrics, such as denim or canvas, it is important to adjust the tension setting. The tension should be adjusted such that the stitches appear even, and the fabric does not pucker or shrink. Adjust the tension in a clockwise direction to increase the tension, and counter-clockwise to decrease the tension.
Using Heavy Weight Threads
When using threads that are heavier than normal, such as metallic threads and other specialty threads, it is important to adjust the tension settings. Increase the tension by turning the tension dial slightly clockwise and check the test seam for evenness.
Troubleshooting Machine Problems
Sometimes, tension issues can be caused by other problems with the sewing machine. Check for any blockages along the thread path and remove them. Also check for any loose screws or worn parts that may need replacing.
Final Considerations
Setting the tension on a Singer sewing machine is relatively simple, but can be quite daunting if you are unfamiliar with the process. Remember to adjust the tension according to the type of fabric and thread being used, and test your stitch before making any final adjustments. With the right technique and a bit of practice, you’ll soon be able to confidently adjust the tension on your machine and achieve great results.
