ABSTRACT
Shuttleless looms overcome most of the aforesaid limitations. e technologies of we insertion in shuttleless looms, which have seen commercial success, can be classied under four heads (Banerjee, 2015):
1. Projectile (partially guided solid carrier)
2. Rapier (fully guided solid carrier)
3. Air-jet (guided uid carrier)
4. Water-jet (unguided uid carrier)
Small we carriers are used in projectile looms for the insertion of pick. e mass of a projectile is around 40-50 g. Rapier looms use exible or rigid carriers which transport the pick across the shed. Fluid looms (airjet and water-jet) utilise uid drag created either by air or by water for the insertion of pick. In contrast to shuttle loom, all the we carriers in shuttleless looms carry the we yarn which is sucient for one pick. Besides, we insertion is done from one side of the loom (generally from the le-hand side). Air-jet is the most popular, whereas rapier is the most versatile among the shuttleless weaving systems. Air-jet loom consumes
the maximum power to produce one square meter of fabric, followed by rapier, shuttle, projectile and water-jet.
