Speed Frame Machine Components

Top rollers are held strictly parallel to and in perfect alignment with bottom rollers.//The bottom rollers of speed frame exercise immense influence on the quality of roving.//The flyer is a special component of the roving frame that helps to insert twist in the roving. The flyer speeds employed normally range from about 1000 to 1400 rpm. The flyers’ special shape offers less air resistance, preventing roving breakages.

Zig-zag and Herringbone Twill Weave

Zigzag twill are those in which the direction of twill is frequently reversed at suitable intervals either across the width or along the length. Herringbone twill are those in which the direction of twill is frequently reversed at suitable intervals either across the width or along the length but not as zig-zag twill and weft yarns floating condition is reversed of the previous yarn.

Woven fabric Structure

The order of interlacement of warp and weft threads at right angles is known as structure of woven fabrics. The interlooping system of yarns is known as structure for knit fabrics. Classification of woven fabric structure: Simple structure and Compound Structure.Methods of fabric representation:❶Warp overlap in which warp is above weft and ❷Weft overlap in which weft is above warp
