What Causes Embroidery Machine thread to break?
Your machine is not properly threaded; Re-threading the machine ensuring the thread has gone through all the guides and the tension properly to suit your embroidery design downloads
There might be burrs in the needle’s eye, within the thread guides, needle plate or the hook; Replace the needle and try buffing the thread guides and needle plate. Buffing may alter the timing, so it’s a good idea to change a damaged hook.
Dry Hook; Given it dries out fastermore quickly, the hook needs regular lubrication. The hook assembly must be lubricated every 4-8 hours of machine running time.
Needle to smallsmaller; You may have to change to a larger needle
A lot of Adhesive spray; You ought to be using only Embroidery design adhesive sprays, do not over use them. Excessive adhesive build up on the needle can make them drag and break threads. If this is happening you must examine the way you use your adhesive spray
Improper timing; If the machine isn’t timed appropriately, you can get many problems besides thread breaks. For example, broken needles, poor stitching or sometimes no stitching.
Old Thread; Thread may become brittle with age and long contact with light, air as well as heat. You need to keep your thread in a cool, dark place to prolong shelf life.
Bruised spool; A bruised spool of thread can come about if your thread falls on the floor, causing the lower winding of thread to loosen and catch as the thread spools off. You could take off the affected section of the thread or exchange the spool.
Machine speed; A few of theembroidery designs add to the stress on thread. You ought to lower the machine speed as required
Lint build up; A lint build up around the tension discs, needle plate or bobbin cases may cause breakage. These areas really should be cleaned regularly with air or perhaps a brush.
Bent needle; This may happen after the needle hits a really hard object for instance a Hoop, needle plate or the hook. If this occursyou have to switch the needle and look for burrs as well as the timing.
Improper tensions; If your tension is too tight, it can cause pulling, puckering and thread stress. When the thread is too loose it may cause the thread to pile up and loop. You need to adjust the tensions to realize a flat smooth look.
Using Tape for loose ends; Using tape can leave a residue and this could cause friction and thread breakage.
