Sewing lovers face a problem when the thread breaks at the wrong moment. Sometimes it is enough to pull up another thread and the problem is solved. But often it doesn't change anything. You need to look for instructions, leaf through, understand, waste time. Having useful information on hand can significantly reduce troubleshooting time.
It doesn't matter what type of sewing machine you are sewing on - manual, foot-operated or electric - the reasons for this problem are the same. Matching the threads to each other So, the first thing to pay attention to is whether the lower and upper threads correspond to each other. Sometimes a slight difference is acceptable for a particular type of stitch, but, as a rule, the threads should not differ much in number. For example, the upper thread is # 40 and the lower thread is # 10 are invalid values. Matching the thread of the fabric The thread may break due to the mismatch of its number with the nature of the fabric. Too thick, thick fabric traps thin thread, makes it difficult to pass, as a result, the thread gathers and breaks. Matching thread number to needle number Even if you can insert thick thread into a needle designed for thinner threads, you will get the already known result - the thread will break. Select the correct thread for the needle and fabric. For this, there must be a special table in the instructions of the machine. This is all about the wrong selection of material. Now let's look at the nuances associated with the mechanism of the machine that lead to the breakage of the thread. Different tension of the threads If the tension of the upper thread does not match the tension of the thread in the hook, the thread may break. There are probably several options here. If the upper thread tension is too tight, the upper thread breaks. To rectify the problem, the tension must be released. There are washers in the machine's mechanism that regulate the thread tension, these washers rotate in opposite directions, and in case of strong tension on the upper thread, the washers must be loosened. If the lower thread breaks, then the tension of the lower thread must be loosened. Its tension is adjusted in the hook. It is necessary to remove it and use a special small screwdriver to loosen the screw, which is in a single amount - you will immediately find it. Problems with the needle First, you may have an incorrectly inserted needle, check it. Second, the new needle may have sharp eyelet edges that cut into the needle. You can change the needle to another, or you can take a strong thread, rub with a polishing paste and polish the eyelet. The choice is yours. And thirdly, you may have a defective needle. General Tips Do not forget to lubricate the clipper with special machine oil. If you use it often, do it once a month. If rarely, then lubricate the machine before using it. On an untreated machine, abrupt start can cause the thread to break. Don't discount the quality of the thread. It can also affect the sewing quality. And, of course, the threads must be properly threaded.
