Early braids had many uses, such as costume decoration, animal
regalia (like camel girths),
sword decoration, bowls and hats (from
palm leaves),
locks (such as those made in Japan to secure precious tea supplies through the use of elaborate knots), and weapons (e.g. slings). Materials that are used in braids can vary depending on local materials. For instance, South Americans used the very fine fibers from the wool of
alpaca and
llama, while North American people made use of
bison fibers. Throughout the world, vegetable fibers such as
grass,
nettle, and
hemp have been used to create braids. In China, Korea, and Japan
silk still remains the main material used. In the Americas, the braiding of
leather is also common. Plaiting with
kangaroo leather has been a widely practiced tradition in rural Australia since
pioneering times. It is used in the production of fine leather belts, hatbands, bridles, dog leads, bullwhips,
stockwhips, etc. Other leathers are used for the plaiting of heavier products suitable for everyday use. For nomadic peoples, braiding was a practical means of producing useful and decorative textiles. In other areas, such as the
Pacific islands (where leaves and grasses are braided), and for many hill tribes, braids are made using minimal equipment. It was only when braiding became a popular occupation in the home or school, as it is in China and Japan, and when the Industrial Revolution came about, that specific tools were developed to increase production and make it easier to produce more complicated patterns of braids. Braids are also very good for making rope and decorative objects. Complex braids have been used to create hanging fibre artworks.
Gold braids and
silver braids are components or trims of many kinds of
formal dress, including
military uniform (in
epaulettes,
aiguillettes, on headgear).
Ropes and cables Braiding creates a composite rope that is thicker than the non-interlaced strands of
yarns. Braided ropes are preferred by
arborists,
rock climbers, and in
sport sailing because they do not twist under load, as does an ordinary twisted-strand rope. These ropes consist of one or more concentric tubular braided jackets surrounding either several small twisted fibre cords, or a single untwisted yarn of straight fibres, and are known as
Kernmantle ropes. In electrical and electronic cables,
braid is a tubular sheath made of braided strands of metal placed around a central cable for shielding against
electromagnetic interference. The braid is grounded while the central conductor(s) carries the signal. The braid may be used in addition to a foil jacket to increase shielding and durability.
Litz wire uses braids of thin insulated wires to carry high frequency signals with much lower losses from
skin effect or to minimise
proximity effect in transformers. Flat braids made of many copper wires can also be used for flexible electrical connections between large components. The numerous smaller wires comprising the braid are much more resistant to breaking under repeated motion and vibration than is a cable of larger wires. Similar braiding is used on pressurized
hoses, such as in plumbing and
hydraulic brake systems in automobiles. Braiding is also used for fibres for composite reinforcements. A property of the basic braid is that removing one strand unlinks the other two, as they are not twisted around each other. Mathematically, a braid with that property is called a
