Fortunately, you don’t need to think too much about it – set up your machine for polyester, and it will cope with most types of poly fabrics without further adjustments being needed. As a general rule of thumb, the upper tension will usually be around a 4.
What number should tension be on sewing machine?
The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing. This should be suitable for most fabrics. If you are doing a zig-zag stitch, or another stitch that has width, then you may find that the bobbin thread is pulled through to the top.
When should I adjust the tension on my sewing machine?
When lower tension is too loose (or upper tension is too tight), knot is visible on right side (left). When upper tension is too loose (or lower tension is too tight), knot is visible on wrong side (right). Tensions can still need adjustment even if they’re balanced.
What tension should I use to sew thick fabric?
The thicker the fabric, higher the tension must be to lift the lower thread up to the middle of the layers of fabric. You will usually be alright with a 4 or 5 on medium to medium-heavy fabrics like linen and twill weaves such as drill and denim.
Why is my thread bunching underneath?
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
What width should my sewing machine be on?
A straight stitch has no width so it makes sense to set the dial at “0”. However, each machine varies so you will want to set the Stitch Width dial at the position where the needle is centered over the stitch plate. This will give you the most accurate seam allowance.
What size needle do you use for polyester?
Knits/Jersey (80/12 Ball Point and Polyester or All-Purpose Thread) Ball point needles are made especially for sewing on knits, such as T-shirt fabric and jersey. The ball point won’t damage or break the fibers as it pierces the fabric.
What stitch should I use for stretchy material?
The best stitch for stretchy fabric is a zigzag stitch. We need a flexible stitch that can get stretched with the fabric. There are different zigzag stitches according to the choice of fabric and it’s use cases.
How do I know if my bobbin tension is correct?
The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.
Can you use thick thread in sewing machine?
Most threads will work as long as they fit through the throat plate of the sewing machine. Stay away from threads and yarns that are too nubby and coarse, like bouclé yarns. And don’t try to use grosgrain ribbons, because they are not flexible enough.
Why won’t my sewing machine sew through thick fabric?
If the presser foot misalignment is too large, place thick paper or fabric (with the same thickness as the fabric being sewn) under the heel of the presser foot to be able to start sewing smoothly.
What tension should I use for cotton?
Cotton requires a moderate tension setting, usually between three and four. Always start adjusting your tension settings with your upper tension.
