BRAIDINGIt began as a handicraft for the constructionof decorative fabrics. The limitations ofknitting and weaving made braiding animportant method of fabric formation intextile composite, rope etc.Introduction to BraidingThe limitations of the weaving,knitting and stitching processesinclude: poor shear resistance limited strength in the primaryloading direction inability to produce complex shapedpartsLimitations of other fabricstructuresDefinition of BraidingBraiding is a simple form of narrowfabric construction. It is done byintertwining of yarns in whateverdirection suited the makers purpose.MAYPOLE DANCE PRINCIPLE3-D braiding3-D braiding is an interesting concept ofcreating a two dimensional array ofinterconnected 2-D circular braids.3-D braids are formed on two basic typesof machines which differ only in theirmethod of yarn carrier displacement. The horn gear type machines offerimproved braid speed over the Cartesianmachines. Cartesian machinesoffer compactmachine size, comparatively lowdevelopment cost and braid architecturalversatility.Types of 3D braiding machineUsesUses Braiding is more significant for industrial fabrics thanconsumer textiles. Braiding is one of the major fabrication methods forcomposite reinforcement structures, with increasingapplications of electrical wires and cables, harnesses,hoses, industrial belts and surgical sutures. Examples of the relatively new application area of braidinginclude reinforcement structures of sporting goods(baseball bats, golf clubs, water skis, snow skis),aerospace and automotive parts. Because of the special properties, braids can be found(often hidden) in many different applications. Someexamples: Clothes and shoes, candle wicks, sash cords,water ski ropes, mountaineering ropes, yachting ropes,parachute lines, fishing nets, mooring lines, medicalapplications such as catheters or dental floss, over braidedhigh-pressure tubes, ground cables or harnessesTHE ENDTHE END
