The history of sewing machines dates back to the first Industrial Revolution and was invented to decrease manual sewing work in clothing companies. The first sewing machine was invented by Thomas Saint in 1790. Home sewing machines are designed for individual use, while industrial sewing machines are larger, faster, and more varied in size and cost. The invention of sewing machines led to the production of ready-to-wear clothing and shoes. Sewing machines have evolved over time, with electronic sewing machines being introduced in the 1970s. Electronic sewing machines have enabled new features such as automating thread cutters, needle positioning, and back-tacking. Sewing machines can make over three dozen distinct stitch formations, with plain stitches falling into four general categories: chainstitch, lockstitch, overlock, and coverstitch. Chainstitch is still used today in clothing manufacture, though it is generally paired with an overlock stitch. Lockstitch is the stitch performed by most household sewing machines. Overlock, also known as serging, is commonly used for garment seams in knit or stretchy fabrics. Coverstitch is formed by two or more needles and one or two loopers.Sewing Machine: Types, Feed Mechanisms, Needles, and Social Impact
Types of Stitches:
- Chain stitch forms a chain-like series of loops.
- Lockstitch is made by interlocking two threads, one passed through a needle and the other coming from a bobbin or shuttle.
- Overlock stitch is formed by one or more needles passing through the fabric and interlooping with a pair of loopers positioned on either side of the needle(s).
- Coverstitch is formed by two or more needles and one or two loopers.
- Zigzag stitch is a variant geometry of the lockstitch.
- Feed is the motion of material being sewn so that each cycle of needle motion involves a different part of the material.
- Types of feed mechanisms are drop feed, differential feed, needle feed, walking foot, puller, and manual.
- Almost all household machines and majority of industrial machines use drop feed.
- Differential feed is used for stretchy materials and overlock machines.
- Needle feed is used only in industrial machines and is useful for sewing heavy materials.
- Walking foot is most useful for sewing heavy materials where needle feed is mechanically inadequate.
- Puller feed is used for large heavy items like tents and vehicle covers.
- Manual feed is used primarily in freehand embroidery, quilting, and shoe repair.
- Sewing machines use special needles tailored to their needs and to the character of the material being sewn.
- Modern sewing machines may be equipped with a needle guard to help avoid injuries.
- Tension in a sewing machine refers to the pull of the thread between the needle and the bobbin.
- Sewing machines have tension discs and a tension regulator.
Industrial vs. Domestic:
- There are mainly two types of sewing machines available: industrial and domestic.
- Industrial sewing machines are larger, faster, and more varied in their size, cost, appearance, and task.
- Industrial machines can handle heavy-duty sewing jobs and are capable of continuous use for long periods.
- Domestic machines have their OEM motors mounted inside the machine, while industrial machines have separate motors mounted to the underside of the table.
- Industrial machines use a clutch motor or a servo motor, while domestic machines use a smaller motor.
- Industrial machines perform a single dedicated task, while domestic machines are more versatile.
- Before sewing machines were invented, women spent much of their time maintaining their family's clothing.
- Sewing machines reduced the time for making clothing, resulting in women having a diminished role in household management and allowing more hours for their own leisure as well as the ability to seek more employment.
- Industrial use of sewing machines further reduced the burden placed upon housewives, moving clothing production to large-scale factories.
- The movement to large-scale factories resulted in a great increase in productivity, reducing clothing prices significantly and increasing the income for families.
- In the long run, unemployed skilled workers gained employment in jobs created as the clothing industry grew.
- The sewing machine's effects on the clothing industry resulted in major changes for other industries as well.
