If you decide to purchase an overlock, it is worth considering one important factor that the quality of its work depends on the correct selection of threads. They must be chosen separately from sewing ones. Even with the ideal setting of the equipment, quality stitching will not be obtained if the wrong thread is used, and the product will have an unrespectable appearance.
Instructions
Step 1
Firstly, the thread for the overlock should be quite thin, since 2-5 threads are used when processing the edge of the fabric. They, intertwining with each other, form a chain. If you use a thread that is too thick (for example, # 40), the seam will turn out to be thick, inelastic and puffy. The optimum thickness for selection should range from # 50 to # 120. But do not choose a thread that is too thin, over No. 120, as it will break at the intersections of the seams and in places of thickening, fray with the needle eyes.
Step 2
Secondly, the overlock thread should be smooth, strong and flexible, without any pronounced defects: knots and terry, etc.
Step 3
Thirdly, it is worth considering the high consumption of threads in the overlock, so the thread should not run out too quickly. Of course, for a small amount of work, a standard sewing winding of 200 meters may be enough. But remember that quality threads are quite expensive. The price per running meter of yarn in a regular bobbin will be three cans higher than in a large winding. There are craftsmen who use cheap threads in working with an overlocker. They sew and are happy with them, but definitely not on all seams, on a maximum of three thread overlock and on the cheapest fabrics. Basically, those who have purchased an overlock strive for high-quality processing of products. If you are not sure about the correct filling of the material and setting up the equipment, then you should start with high-quality threads.
Step 4
Never use Soviet-made cotton threads purchased 20-25 years ago in an overlock; such material will not work with modern technology. Lavsan and reinforced threads of Russian manufacturers marked LL (flax + lavsan) and LH (cotton + lavsan) are also not suitable. The above threads can cause rapid wear of the overlock. Because even when the disc tensioners are set to their maximum value, the required tension is not created. You should also not use threads that are used for industrial single-stage overlocks, as they may only be suitable for some seams. It is worth considering that modern household overlocks are multi-operational, with a large number of functions and they have different whims for threads. By trial and error, you need to choose the best option for your equipment.
