What Causes Embroidery Machine thread to break?
Here are a few reasons why you embroidery thread may be breaking, The first and most obvious one is your machine is not properly threaded try re-threading your machine ensuring the thread has gone through all of the guides and the tension properly. If this is not the problem then you might consider these other possibilities.
There may be burrs in the needle’s eye, on the thread guides, needle plate or the hook; Change 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 defective hook.
Dry Hook; Since it gets dry faster, the hook must have regular lubrication. The hook assembly needs to be oiled every 4-8 hours of machine running time.
Needle too small; You should to change to a larger needle
An excessive amount of Adhesive spray; You need to be using exclusively Embroidery designed adhesive sprays, do not over use them. An excessive amount of adhesive build-up on the needle can make them drag and break threads. If this is occurring you need to take a look at the way you use your adhesive spray
Improper timing; If your Embroidery machine isn’t timed appropriately, it can cause many problems along with thread breaks. For example, broken needles, poor stitching or at times no stitching.
Old Thread; Thread can be 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 extend shelf life.
Bruised spool; A bruised cone of thread can occur when the thread falls on the floor, causing the lower winding of thread to undo and catch as the thread spools off. You can remove the affected part of the thread or exchange the cone.
Machine speed; Some Embroidery designs increase 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 could cause breakage. These areas ought to be cleaned regularly with air or maybe a brush.
Bent needle; This may happen after the needle hits a really hard object possibly Hoop, needle plate or the hook. If this occurs you have to replace 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. If the thread is too loose it can cause the thread to stack up and loop. You have to alter the tensions to achieve a flat smooth look.
Using Tape for loose ends; Using tape can leave a residue and this can cause friction and thread breakage.
