Sewing machines can run smoothly and reliably for years to come if they are properly setup, and regularly oiled and serviced. But, another important thing to remember is that the bobbins and needles you use, and the winding of bobbins must be perfect for flawless stitching, and avoidance of any sewing problems and damage to the machine.
Bobbins
You need to use the right kind of bobbins that suit your machine type. Your machine manual states the kind of bobbin your machine requires. Make sure you use only the mentioned bobbin type. Any kind of changes to the shape, size, type, or material of bobbin will affect not only the stitch, but may also damage the machine. Also, make sure you get A-grade quality bobbins from reliable and trustworthy metal bobbin manufacturers in India like Trim Engineering Services.
Needles
Just as much as the right kinds of bobbins are required, equally important is the usage of the right needles. The wrong size of needle can result in needle breakage, thus damaging the machine and causing safety hazards for the operator. Every fabric requires a different needle size to be sewn. Going up or down even one size can affect the stitch and functioning of the machine. Needles are sized from 8 to 18. A size 9 to 11 needle is appropriate for delicate and lightweight fabrics like chiffon, organza, and silk. A size 14 needle is best for medium-weight fabrics like cotton, linen, and suedes. And, a size 16 needle is designed for heavy-weight fabrics like denim and velvet.
Bobbin winding
Once the appropriate bobbins and needles are selected, it is crucial that you wind the bobbins properly. Improper winding may disrupt the timing of the machine, break needles, create downtime from clearing tangled thread, and require expensive machine repairs. To avoid all of this, it is important to wind bobbins properly, or use pre-wound quality bobbins. This will not only bring smooth finishes, but will also increase efficiency of the sewing operations. If not properly wound, there may be multiple issues you may have to face.
Threading the machine
Bunching thread under the fabric – When you have a perfectly straight stitch on the top of the fabric, and thread bunching at the bottom, you may tend to think that the bobbin is not wound properly. But, the truth is that there is no tension on the upper thread. To resolve this, you need to raise the pressure foot lifter and rethread the machine. Next, you will need to raise the take-up lever and needle to the highest position as per your machine’s manual. This way, you will have the right tension.
Apart from making sure that all of the above is appropriately done on your machine, there are a few other tips you must follow too. Experts recommend that you replace your needles every 16 hours of usage. This will avoid the needles from breaking, bending, and being damaged. Also, remember not to force the fabric under the feed dogs by pulling it from behind. This will result in messy stitching, and can even break your machine. Let the fabric move smoothly on its own.
