Types of Fabric Weaving Looms
A textile is woven by interlacing the warp and weft threads in a regular pattern both lengthwise and widthwise during the weaving process. The technique is carried out with the help of a loom. Virtually in every instance, the interlacing of two sets of yarns is performed at a right angle to the other set of yarns. The warp is the segment of the loom that traverses the length of it, while the filler, weft, or woof is the cross-section that accomplishes this. When the rising and lowering sequences of the warp threads are varied, the result is a diverse range of weave topologies.
The Different Types Of Modern Weaving Machine
Looms may be divided into a variety of categories. Cotton looms, woolen looms, sack looms, silk looms, and other types of looms may be classified according to the kind of fabric fibers used in their production. For example, looms may be split into two groups based on the kind of weft insertion used: shuttle looms and shuttleless looms like weaving loom machine, which are both types of looms.
Shuttle looms are looms that insert the weft with the use of conventional shuttles (made of wood or plastic). The shuttle is huge and heavy in weight, and it is regularly launched into space by exchanges of passengers. The machine has a lot of vibration, makes a lot of noise, moves slowly, and has a poor efficiency.
The weft insertion techniques used on weaving loom machine are diverse, and include rapier, jet (air jet, water jet), projectile, multi-shed (multi-phase), and weaving, among other options.
1.The rapier weaving machine , which may be either rigid or flexible, uses rapier heads and belts to grip and guide the warp. In addition to being suitable for weaving plain and textured fabrics, rapier weaving machines are characterized by their ease of color change, making them suitable for the production of multi-color weft fabrics as well as the production of yarn-dyed, double-layer fleece fabrics, terry fabrics, and decorative fabrics, among other things.
- Air-jet loom: the weft yarn is drawn through the shed by the jetted compressed air flow, and the warp yarn is drawn through the shed. The fastest and most productive aspect of an air-jet loom is its high speed and labor productivity.
- The water jet loom, which uses water as the medium for weft insertion and creates frictional traction on the weft yarn, allowing the weft yarn on the fixed bobbin to be inserted into the shed. The water jet loom is characterized by its high speed and high unit output, and it is mostly used for the manufacturing of hydrophobic filament chemical fiber textiles with a smooth surface texture.
Weft clamping is accomplished using a little gripper and a clip on the weft, and the weft is entered after it has been clamped. In addition to the benefits of reliable weft insertion, good fabric quality, and the use of just a few weft threads, projectile looms are also well suited for the manufacture of multi-color weft textiles, fine thick fabrics, and broad fabrics.
History of Looms
When it comes to the history of looms, it’s important to remember that the history of civilization is also, to a certain degree, the history of textiles. There have been allusions to beautiful garments manufactured from the filament of silk in China, despite the fact that earlier civilizations utilized coarser threads to create clothes that were rough and harsh in appearance.
The rapier weaving machine is currently the most widely used shuttleless weaving loom machine. In addition to the characteristics of high speed, high automation and high-efficiency production of shuttleless weaving loom machine, its active weft insertion method has strong variety adaptability and can adapt to Weft insertion of all kinds of yarns, and rapier weaving machine also have obvious advantages in multi-color weft weaving, which can produce yarn-dyed products with up to 16-color weft yarns.
With shuttleless weaving loom machine replacing shuttle weaving loom machine, rapier weaving machine will become the main production machine for woven fabrics.

Loom Workflow flow:
Let-off —- Shedding —- Weft Insertion —- Weft Battening —- Take up
The warp yarn of the corresponding length is released from the weaving shaft, so that the warp and weft yarns are continuously intertwined to ensure the continuous weaving production process, which is called warp let-off.
(1) According to the weft density of the fabric, the warp of the corresponding length is sent out in time during the weaving process to maintain the continuous weaving production.
(2) Apply tension to the warp yarn that meets the technological requirements, and keep the warp yarn tension stable during the weaving process.
Different types of fabrics require different tension on the upper machine when weaving. Once the let-off mechanism adjusts the tension on the upper machine, in the weaving process, the weaving shaft should maintain a constant and consistent tension on the warp yarn from large to small. This is a measure of The main indicator of the performance of the let-off mechanism.
The size and stability of warp tension depend to a large extent on the amount of let-off.
The opening mechanism is generally composed of a lifting device, a returning device, and a control device for the lifting sequence of the Heald Frame (Heald Wire).
- Separate the warp yarns up and down to form a shed for the weft inserter to pass through;
- Control the ascending and descending order of the warp yarns according to the requirements of the interlacing rules of the warp and weft yarns of the fabric weave.
On the loom, weft insertion is to introduce the weft yarn into the shed formed by the warp yarn opening, so that the warp and weft interweave to form the fabric.
Function: Introduce the weft yarn into the shed, so that the warp and weft yarns are interwoven into a fabric.
On the loom, relying on the reed of the beating-up mechanism to reciprocate back and forth, the weft yarns introduced into the shed one by one are pushed to the loom, and the process of interweaving with the warp yarns to form a fabric that meets the design requirements is called Weft Battening movement.
Function: Push the weft yarn introduced into the shed to the loom, tighten the weft yarn, and form a fabric.
After the weft yarns are driven into the weft to form fabrics, these fabrics must be continuously drawn away from the weft and wound onto the cloth roll, which is called Take up.
rapier weaving machine use rigid or flexible rapier heads, belts to hold and guide the weft. In addition to being suitable for weaving plain and textured fabrics, rapier looms are characterized by easy color changing, suitable for multi-color weft fabrics, and are suitable for the production of yarn-dyed, double-layer fleece fabrics, terry fabrics and decorative fabrics.
