Sewing machine principle

For every lady who loves beauty, buying clothes, shopping and dressing up can be said to be a compulsory course in life. In daily life, we often hear people say: "There is always a piece of clothing missing in a woman's wardrobe." This is enough to show how much women love clothes. However, in daily life, we often encounter the situation where our clothes have a little hole. When faced with such a situation, what will you do?

I believe that most people will not throw away clothes just because of small holes in them. After all, they are just small holes that can be patched with needle and thread. However, needlework requires a technical job and not everyone can sew well. At this time, we might as well consider using a sewing machine.

Sewing machine is a machine that people use to produce large quantities of high-quality clothes at the lowest cost in modern life. Now life is the easiest loop stitch is the chain stitch. To create a chain stitch, the sewing machine will loop the same length of thread behind the thread. The fabric sits on a metal plate underneath the needle and is held in place with a presser foot. At the beginning of each stitch, the needle pulls one loop through the fabric. A coil-making device catches the coil before the needle is pulled out, and the device moves synchronously with the needle. Once the needle pulls out of the fabric, the feed dog assembly pulls the fabric forward. When the needle passes through the fabric again, the new loop will pass directly through the middle of the previous loop. The coil making device will grab the thread again and make a coil around the next coil. This way, each coil holds the next one in place.

The above is the working principle of a sewing machine. We can see that it is not difficult to use a sewing machine, and the effect of using a sewing machine is better than using needle and thread to mend clothes. It is easy to operate, does not take time or effort, and clothes sewn by a sewing machine generally do not have obvious sewing marks. Therefore, every family may consider placing a sewing machine.
