Out of these single phase looms, Air jet loom is having maximum speed
and maximum weft insertion rate. Because of the very high quality of yarn
required, the yarn must be of very high standard, otherwise the loom
stoppages due to warp breaks and weft breaks will be high. The
efficiency achieved will be in the order of 93 to 95%.
Other looms like projectile and repair will give an efficiency of about 90 to 95%. The cover of the fabric in air jet will not be as good as projectile and rapier looms. Efficiency in multiphase loom is in the order of 90 to 95% These are the speeds obtained by the weavers at commercial level. The main reason for targeting higher productivity is to reduce the cost of production, especially labour cost. The increase in speed is being achieved the improvement in all major functional parts of the modern looms Today the market particularly demands wide variety as much as possible at the lowest possible cost. These machines provide the feature such as :
The terry plus airjet terry weaving machines of Gunne not only permit greater pile height and heavier fabrics, it also offers greater flexibility in operation with the ability to change the fabric width and pile height. On the machine the drawing width can be changed using the same reed, simply by shifting the weft stop motion and the weft cutter. The pile height is programmable within the same fabric. Special fabric constructions with different pile heights on front and back are also possible. For Sulzer P7300 projectile looms a variety of back rest roller and cloth take up systems are available to suit the density and the type of fabric woven.

The increase in speed is being achieved the improvement in all major functional parts of the modern looms Today the market particularly demands wide variety as much as possible at the lowest possible cost. These machines provide the feature such as :
- The possibility of weaving more difficult products in terms of yarn employed and also in combinations
- Application potential in all weaving sectors.
