Sewing machine is a machine which is used to sew two or more pieces of fabrics together. A sewing machine sew not only fabrics but also other materials, such as bags, lather, tent and more. Sewing machine is also used to improve the fineness and appearance of fabrics. Different sewing machines follow their own duty to produce perfect products as we want, such as garments, mattress protectors, etc.
In textile industry, two types of sewing machines are used: manual swing machine and electric sewing machine.
Manual sewing machine is powered by hands or legs. That is to say, the users have to operate the machine by their own hands or legs. Comparing with electric sewing machine, the production capacity of manual sewing machine is low. Due to its low cost and easy use, most of sewing machines are used in a trailer shop or home, which are usually used by mattress protector manufacturers.
Electric sewing machine is driven by electrical power, so it works quickly and smoothly. Due to its high production capacity and efficiency, it is also called industrial sewing machine. Some common types of industrial sewing machine includes lock stitch machine, chain stitch machine, over lock machine, zigzag stitch machine, blind stitch machine, etc.
Some machines have been programmed to make automatic sewing. However, this kind of machines are expensive and difficult to maintain. Although they can produce better goods than others, they are rarely used in our country.
