Bobbin threads for industrial machine embroidery
They may only be visible on the reverse side, but they are of tremendous importance. Roughly speaking, you always need at least half of the length of the top thread for the matching bobbin thread. The two work together to produce the embroidery; therefore you should take care to complement the quality top threads with the corresponding bobbins.
The importance of bobbin threads for embroidery
The bobbin threads affect the productivity during manufacturing and the beauty and resistance of the result. It is very important to set the tension of all threads you are using correctly and efficiently. This will ensure that the bobbin threads do not show on the front side and will reduce the risk of breaking or looping. When used for garments, the bobbin threads come into contact with the skin and they should feel soft and be safe. They should also have the proper resistance to the treatments the final product will need to withstand during wearing or cleaning. Madeira offers many versions of polyester bobbin threads that are washable at 95°C and certified by Oeko-Tex class I.
Self-winding bobbin threads or pre-wound bobbins?
The choice between the two options is really a matter of preference or habit. There are arguments in favour of each: for both the ready-to-use bobbins and for winding them yourself. You only need to test and decide which is the most convenient for each of your projects.
Ready-made for convenience and perfection
Pre-wound bobbins are suitable for a wide range of embroidery machines, but you should first ensure that they fit and will perform on yours. You will benefit from their usage in terms of speed, planning and convenience. All you need to do is to place them in the bobbin case and then you are ready to start. A constant tension and quantity of thread ensure that you won't need to interrupt your work for adjustments and you can better plan the frequency of replacements. A perfect consistency in tension is provided by magnetic bobbins.
Cones for flexibility and economy
There are various thicknesses of threads on cones that can be used for self-winding. These offer an economical solution at the cost of additional time, tools and work. Often the tension is not as stable as for the pre-wound bobbins and the quantity varies each time and is smaller. The result is less accurate and the bobbins might need to be changed more often. For multi-head machines, this also means more interruptions at different moments. With fine bobbin threads, one can fit a larger quantity onto a bobbin, while the large cones will save more money and will last longer.
