Weaving Mechanism of Woven Fabric?

Weaving Mechanism of Woven Fabric?

Answer:

Weaving Mechanism:

The process of producing a fabric by interlacing warp and weft threads is known as weaving. The machine used for weaving is known as weaving machine or loom. Weaving is an art that has been practiced for thousands of years. The earliest application of weaving dates back to the Egyptian civilization. Over the years, each the method in addition because the machine has undergone extraordinary changes. As of these days, there's a good vary of looms getting used, right from the only hand loom to the foremost sophisticated loom.

Classification of Weaving Machines:

Weaving machines are classified consistent with their filling insertion mechanism. The classification is as follows:

1. Shuttle
2. Shuttle-less

 Projectile
 Rapier
 Air-Jet
 Water-Jet

Shuttle Weaving:

In shuttle weaving, a shuttle that traverses back and forth across the loom dimension inserts the filling. Shuttles are often made from wood or plastic. Filling yarn is wound on the quill and also the quill is placed within the shuttle. because the shuttle moves across the loom, the filling yarn is unwound from the pirn and lay within the shed.

Projectile Weaving:

Projectile weaving machines use a projectile equipped with a gripper to insert the filling yarn across the machine. The gripper projectile draws the filling yarn into the shed. The Projectile glides through the shed in a rake- formed guide. Braked within the receiving unit, the Projectile is then sent to its original position by a transport device put in below the shed.

Rapier Weaving:

In rapier weaving, a versatile or rigid solid component, referred to as rapier, is used to insert the filling yarn across the shed. The rapier head picks up the filling yarn and carries it through the shed. when reaching the destination, the rapier head returns empty to pick up following filling yarn, that completes the cycle. A rapier performs a reciprocal motion.

Rapier weaving machines are often of 2 types:

1. Single rapier Machines: 

One, rigid rapier is used in these machines. The rigid rapier may be a metal or composite bar sometimes with a circular cross-section. The rapier enters the shed from one side, picks up the tip of the filling yarn on the opposite side and passes it across the loom dimension whereas retracting. Therefore, one rapier carries the yarn in a method only and half the rapier movement is wasted. additionally, there's no yarn transfer since there's just one rapier. the one rapier’s length is up to the dimension of the loom.

2. Double rapier Machines: 

2 rapiers are used in these machines: one rapier, referred to as the giver, takes the filling yarn from the yarn accumulator on one side of the loom, brings it to the middle of the machine and transfers it to the second rapier that is termed the taker. The taker retards and brings the filling yarn to the opposite side. like the one rapier machines, only half the rapier movements are used for filling insertion.

Air-Jet Weaving:

The air jet weaving machines are the weaving machines with the best weft insertion performance and are thought-about because the most efficient within the producing of sunshine to medium weight fabrics, ideally made from cotton and sure synthetic fibers (sheets, cloth fabrics, linings, taffetas and satins in staple yarns of synthetic fibers); it's any way to be acknowledged that technically positive results are obtained at the present additionally with significant weight fabrics (denim) which some makers manufacture additionally machine models for terry production.
These machines are the perfect resolution for people who need to provide bulk quantities of customised fabric designs. The weaving widths vary typically from one hundred ninety to four hundred cm. As regards the multicolored weft carrier, up to eight completely different wefts will be fed. it's to be thought-about that the air jet weaving machines need a high-energy consumption to organize the compressed gas which this consumption rises undoubtedly with increasing loom dimension and running speed. The reduction within the energy consumption is, after all, one among the most issues of the makers, and builds for the user a vital choice criterion.

Water-Jet Weaving:

A water-jet weaving machine inserts the filling yarn through the extremely pressurized water. The relative velocity between the filling yarn and also the water jet provides the attraction. If there's no speed distinction, then there would be no tension on the yarn ends up in curling and snarling of the yarn. Water-jet weaving machine will solely be used for hydrophobic fibers.
