Weaving machinery introduction
May 08, 2018

The weaving machine is a device that forms warp and weft warp and weft perpendicularly intersecting each other to form a fabric. In the weaving process, the weaving machine introduces the weft yarns into the spread warp yarn layer (consisting of several warp yarns of the same length arranged in parallel) so that the warp and weft are interlaced to form the fabric. This process is called "weft insertion". Weft insertion methods for weaving machinery include shuttle weft insertion and shuttle less weft insertion. Weaving machinery is also divided into shuttle looms and shuttle less looms. The shuttle weaving machine adopts the traditional weft insertion method. The shuttle introduces the weft yarn into the opened warp yarn layer. The shuttle is generally made of wood or composite material that is impact-resistant, wear-resistant, tough, and has certain elasticity; During the working process, the shuttle needs to be projected repeatedly to complete the weft insertion. Due to the large volume and heavy weight of the shuttle, the shuttle looms have large vibrations, high noise, slow speed, and low efficiency. Shuttle less weaving machines use a small, lightweight weft feeder (such as air or water jets, rapier heads) instead of shuttles for weft insertion; shuttle less weaving machines have been introduced to the market since the 1950s. With the advantages of light weight, low vibration, low noise, fast speed, and high insertion rate, the shuttle weaving machine is continuously replaced, and the shuttle less transformation of weaving machinery has become the trend of the global looms market. At present, the proportion of shuttle less looms in developed countries has reached more than 90%. Shuttle less looms are classified into rapier looms, air jet looms, water jet looms, and projectile looms, depending on the type of weft insertion carrier.
