Embroidered patches can be attached with a pin, sewn on, or affixed with more modern methods such as iron-on, dryer heat-activated adhesive, and Velcro backing.
Embroidered patches—an important identification tool for military and other uniformed personnel—trace their roots thousands of years ago to ancient cultures of the Mediterranean, Mideast, China, India and South America, where the art of decorating fabric with thread stitching originated.
Youth groups, including sports teams, scouting organizations and specialized clubs, often wear clothing emblazoned with embroidered patches.
[1] As with other forms of heraldry, the colours and images in military patches are chosen to symbolically convey different positive traits and values.
SSI became common during World War II and distinctive patches for individual units of the US Army, Navy, Marines, Air Force, and Coast Guard have become a proud tradition.
Embroidery—once a time-consuming hand-made stitch-by-stitch process—was revolutionized by the introduction of the Schiffli embroidery machine, invented by Isaak Groebli of Switzerland in 1863.
Early production from the multi-needle machine, powered by a hand-turned crank, wasn’t much quicker than handwork, but significantly, multiple copies of identical designs could be created.
[4] An automatic machine, refined by Isaak’s eldest son in 1898, simplified the mechanical system so it could be run by a single operator.
Images previously created by hand in a time-consuming process can now be quickly, digitally scanned, and computer-controlled, with multi-head sewing machines use several colors of thread simultaneously.
Other modern advancements include applying a plastic backing to the patch, improving stiffness, and preventing bunching or wrinkling of the design.
