The advent of the sewing machine directly led to the mass market and assembly line production of clothing.
The invention of the sewing machine can be traced back to the 18th century. In order to improve the production efficiency of shoemaking, the British Thomas Sainter thought hard and designed a machine with single chain stitch for sewing boots and shoes. In 1790, he built the first hand-operated sewing machine in London with a wooden body and some parts made of metal.
Although this machine was crude and impractical, it opened the door to the invention of the sewing machine. Because there was no record of sewing machinery manufacturing at that time, his patent was placed in the patent library of textile machinery and was ignored for 83 years. Later, the machine was copied and exhibited at the 1878 Paris International Exhibition.
In 1885, the Singer Vibrating Shuttle sewing machine designed by Singer Company used the method of vibrating shuttle sewing machine, which was more usable than the swing sewing machine at that time. Selling millions of machines, it became the world's first truly practical household sewing machine until it was replaced by the rotary shuttle sewing machine in the 20th century.
Sewing principles of sewing machines:
The basic principles of most sewing machines are the same. The core of a car is the internal combustion engine, and the core of a sewing machine is the coil stitching system. The loop stitching method is very different from ordinary hand sewing. In the simplest form of hand stitching, the sewist ties a piece of thread through a small eye at the end of a needle and then threads the needle and thread completely through two pieces of fabric, from one side to the other, and then back to the original side.
In this way, the needle drives the thread in and out of the fabric, sewing them together. While this is very easy to do by hand, pulling with a machine is extremely difficult. The machine needs to release the needle on one side of the fabric and then instantly grab it again on the other side. Then it involves pulling all the loose threads out of the fabric, turning the needle around, and repeating all the steps in the opposite direction.
This process is too complicated and impractical for a simple machine, and even by hand it only works well with shorter threads. Instead, the sewing machine only pushes the needle partially through the fabric. On a machine needle, the eye of the needle is just behind the tip, not at the end of the needle.
