Each woman, keen on sewing, early orlate faced with the need to purchase an overlock. However, when the treasured device was purchased, one of the first problems of a happy owner is the selection of the right threads for it. So, what is the difference between the specialized threads for overlock from conventional and why is it so important to use them?
Before you deal with threads, it's worth freshening upIts knowledge of what an overlock is, than it differs from a standard sewing machine. It basically makes two types of seams: straight stitch and zigzag. While the first kind allows to connect two or more pieces of fabric, the second one is often used for edge lapping. However, in the case of thin or trailing tissues, the zigzag is ineffective because it stretches and deforms the material. Unlike the sewing machine, the nibs neatly allows you to process the edges. He does not stretch the fabric, cutting the excess. To form a seam, two to five threads are used. The more they have a particular model, the more types of seams it is able to do.
Overlocks are household and industrial.As a rule, the hulls of the first models consist of plastic. Such devices are less demanding on threads and resources. In this case, they can usually perform several types of joints. Industrial overlocks are designed for hours of work. Therefore, their design is simpler and more reliable. In this case, they are usually able to perform only 1-2 types of stitches.
Sometimes the overlock is confused with a stitching machine(raspashivalkoy). It is able to make flat seams. It is designed for the manufacture of knitwear, elastane and other fabrics of similar properties. There are hybrid devices - koverloki. They are able to make flat seams and grind the edge. All of the above devices are rather capricious to sewing threads and often deliver their owners a lot of problems in this matter.
Нитки для оверлока, как и иглы, – это один из тех factors on which directly depends not only the quality of the future product, but also the service life of the sewing machine itself. Improperly selected, they can damage the shuttle of the device. In addition, the process of sewing itself depends on the quality of this type of fittings. After all, unsuitable threads will be confused, torn or simply slow down the machine.
First of all, unsuitable for overlockers,carpet weaving and flat-stitched machines are cotton threads. They have insufficient elasticity and strength, because of this, often tear during work and deform the plastic parts. Also, do not use very popular lavsan and reinforced threads. Despite their strength, they can also cause a breakdown of overlocks, as they can not create the necessary tension.
There are a huge number of manufacturersaccessories for overlocks: Ideal, Gamma, AMANN Group Mettler, Gutermann, Alterfil, etc. Each of them produces several types of their products. Despite this, three main types of threads for overlockers are distinguished:
Choosing the thread for the overlock, it is first of all to look at their composition. The fibers must be 100% synthetic. Threads of this type are much stronger than natural, as well as mixed.
Also it is worth remembering that the type of tissue shouldmatch the type of threads used. Otherwise, when washing and ironing the finished product, unpleasant incidents may occur. Thickness also plays a very important role. Overlock seam is an interlacing of two or more threads. And if they are fat, it will look gross. It is best to use the thread of the following numbers: from 50 to 120. And among the textured, they are best suited for overlock models No. 100, 120 and 250. When buying hardware from an unknown manufacturer, it is worth to assess the quality of the thread. It should be smooth, without knots, thickenings and noticeable defects. As for length, the best option is to buy 1000-meter coils. They are not very expensive. They will be enough for a long time.
Household overlock, compared with sewingmachine, is more expensive. Therefore, some lovers sew to save money, buy household overlock 51 class. Despite the fact that they are unacceptable for the processing of very thin fabrics and in many respects inferior to modern models, otherwise the instruments can become an indispensable assistant in the sewing business. As for the selection of threads, in this aspect the overlock of class 51 is universal. You can buy any, including Soviet cotton. It is important that all threads of the industrial overlock are of the same thickness. In addition, for each version used, it is necessary to individually adjust their tension.
In the CIS, due to climate, in dwellingsit is customary to make floors. Due to the fact that the situation in each house is unique, when buying a carpet, carpet and similar products they have to be cut. To make the edges look neat and not strewed, they are overlaid on specialized devices. Such sewing machines require a separate type of polypropylene thread. These threads for carpet overlock are not only durable and elastic, but they do not crumble or break over time. In addition, they easily tolerate freezing temperatures. The disadvantages of this type of thread include the fact that they fade a little in the sun.
В отличие от обычной швейной машинки, в которую there is only one thread (in rare cases, two), in the overlock it is necessary to fill several - from two to five. And in some cases, this is quite a laborious task. To facilitate their work, many professional seamstresses use one technique. They simply tie new threads to the old fragments at the base of the coil, pulling them up to the needle itself. And then they cut the knot and fill it with a needle. This method can be used by all. But it is worth remembering that this refueling should be done only with the raised foot. The first time to fill the thread in the overlock, you can ask the seller to purchase or use the instructions for the device.
Proper selection of threads for overlock is very importantfor its further work and quality of finished products. In this case, every woman should herself figure out which thread is better suited for her typewriter. In this case, this surprisingly useful device will serve her faithfully for many years, helping to embody all creative ideas.
