FABRIC SCIENCE AND ANALYSIS

AIR JET LOOMS

Presentation By: Payal Gupta

INTRODUCTIONAir jet weaving is done on an air jet loom,which propels yarn called “Weft" by using ajet of air. Weft yarn fills in the lengthwisepattern set down first by the “Warp" yarn.

Shuttle less Weaving Machines are generally of wider widths enabling the simultaneous weaving of two or more widths; up to 400/420 cms. in the case of Air Jet.

SHUTTLELESS LOOM AIR JET (I)

Jet looms take the weft yarn across the loom by using a high speed of either air or water

The force of air or water carriers the yarn from one side to the other.

Jet looms are faster than projectile or rapier looms (picks per minute).

Multiple Air nozzles are used to insert the weft yarn into the shed

SHUTTLELESS LOOM AIR JET (II) With the air-jet looms, the initial

propulsion force is provided by a main nozzle.

Relay nozzles (auxiliary nozzles) along the shed produce additional booster jets to help carry the yarns across the loom.

The fabric width of air-jet loom is normally narrower than rapier or projectile loom

ADVANTAGES High productivity. Low initial outlay. Multicolor weft insertion up to 6 colors. Unusual electronic features like: Bidirectional communication with host

computer. Automatic pick repairing.

Automatic controls on weft insertion timings.

More reliability.

Minimum maintenance.

Less spare parts reqiured.

DISADVANTAGES

Power consumption due to compressed air.
