Working Principle And Types Of Weaving Machine

Bysuntech

A weaving machine is a machine that is used to weave fabric and tapestries. The primary function of any loom is to keep the warp threads taut in order to permit the interweaving of the weft threads. The specific design and mechanics of the loom may differ, but the core function remains the same. The first weaving machines were entirely hand-operated looms. Shuttleless loom technology has been investigated since the nineteenth century, and numerous innovative shuttleless looms have been introduced to the market one after the other since the 1970s. The weaving loom machine is currently an essential part of the weaving process in the textile industry.

The Weaving Machine’s Operation Principle

The separation of the weft yarn bundle from the shuttle or the carrying of just a little quantity of weft yarn is the fundamental characteristic of shuttleless weaving machines. The use of a tiny and light weft inserter instead of a big and heavy shuttle creates suitable circumstances for high-speed weft insertion. The bobbin package is directly employed in the supply of weft yarn, and it enters the weft insertion mechanism via the weft storage device, allowing the loom to avoid frequent weft replenishment.

The usage of a shuttleless weaving machine is very important for enhancing fabric variety, changing fabric structure, decreasing fabric flaws, improving fabric quality, lowering noise, and improving working conditions. Shuttleless looms have a fast speed and an efficiency that is 4-8 times that of shuttle looms. As a result, the widespread use of shuttleless weaving machines may significantly boost worker productivity.

 

Weaving Machine Types

Machine for Weaving Rapiers

Rapier weaving machines hold and guide the weft using rigid or flexible rapier heads and belts. Rapier looms, in addition to being suited for weaving simple and textured textiles, are distinguished by their ease of color change, suitability for multi-color weft fabrics, and suitability for the manufacture of yarn-dyed, double-layer fleece fabrics, terry fabrics, and ornamental fabrics.

Weaving Machine Using Air Jets

Compressed air jets pull the weft threads through the shed in air-jet weaving machines. The fastest and most productive aspect of air-jet weaving machines is their high labor productivity. They are appropriate for the manufacturing of simple and textured textiles, fine and extremely high-density fabrics, and large-batch fabrics.

Weaving Machine with Water Jets

Water is used as the weft insertion medium in water jet weaving machines to provide frictional traction on the weft yarn with the jet water flow, allowing the weft yarn on the fixed bobbin to be inserted into the shed. Water jet weaving machines have a high speed and unit output, and are mostly used to produce hydrophobic filament chemical fiber textiles with a smooth surface.

Machine for Weaving Projectiles

Projectile weaving machines use a tiny gripper to retain the weft and project the weft insertion. The benefits of the projectile weaving machine are steady weft insertion, great fabric quality, and a small number of weft threads. It may be used to make multi-color weft textiles, fine, thick, and dense fabrics, and broad fabrics.

the Loom’s Composition

  1. Opening: The warp strands are divided up and down according to the fabric structure to generate a shed for weft insertion.
  2. Weft insertion: the introduction of weft yarn into the shed.
  3. Beating-up: To make a fabric, push the weft yarn introduced into the shed to the weaving mouth.
  4. Coiling: The woven fabric is coiled into a certain package after being dragged away from the fabric forming region.
  5. Let-off: provide the warp in accordance with the interlacing requirements, and make the warp have a particular tension.

Sixth, the frame, starting, braking, and gearbox.

  1. Protection device: prevents weaving faults and ensures safe operation.
  2. Automatic weft filling device: It will automatically fill the weft once the weft yarn has been used up.
  3. Multi-color weft feeding device: provide various weft yarns alternately for interweaving without pausing.
