Types of Rapier Loom

 

Since shuttle looms have obvious problems such as low weft insertion rate and poor product quality, shuttleless looms are replacing shuttle looms, and shuttle looms will eventually be eliminated. According to different weft insertion methods, shuttleless looms include rapier looms, jet looms, air-jet looms, water-jet looms and projectile looms. Among shuttleless looms, the weft insertion principle of the rapier loom was first figured out. At first, it was a single rapier, and later a rapier loom with a double rapier for weft insertion was invented.
Since the 1950s, following the rigid rapier, flexible, steel belt, two-phase, telescopic, double-layer, three-layer and other forms of rapier looms have appeared and been put into industrial production. With good variety adaptability, it is widely used in yarn-dyed, terry, silk, linen, wool and other industries. It has now developed into a shuttleless loom with many models and large quantities. In recent years, rapier looms have been popular among textile enterprises for their flexibility, versatility, and wide variety adaptability. They account for a considerable proportion of shuttleless loom production. The technology is mature and the level is high.

Weft insertion principle of rapier loom

The weft insertion method of the rapier loom is to use a reciprocating rapier as a weft insertion device to insert or clamp the weft yarn, and introduce the weft yarn on the fixed bobbin outside the machine into the shed. There are many forms of weft insertion for rapier looms, which can be classified according to the following characteristics. Click Here to visit more rapier loom

Rapier configuration quantity

Rapier looms are divided into single rapier weft insertion and double rapier weft insertion according to the number of rapier configurations.
Single rapier weft insertion is only equipped with a long rapier wider than the cloth width and its rapier transmission mechanism on one side of the loom, which sends the weft yarn into the shed to the other end. Or extend the empty rapier into the shed to hold the weft yarn on the opposite side, and then pull the weft yarn into the shed during the withdrawal process to complete the weft insertion.
Double-rapier weft insertion is equipped with rapiers (weft-feeding swords and weft-receiving swords) and corresponding sword-transmitting mechanisms on both sides of the loom. During weft insertion, the weft yarn is sent to the center of the shed by the weft-feeding sword, and then delivered to the opposite side to the weft-receiving sword that has also moved to the center of the shed. The two swords then return separately, and the weft joining sword pulls the weft yarn through the shed to complete the weft insertion.

Twist Test Methods and Influencing Factors

Image
  Twist test is an important part of yarn inspection. It is related to the strength, elongation, appearance, style, etc. of yarns and fabrics. Different yarns have different structural characteristics, and their twist testing methods are also different. Basic concept To understand twist testing, you must first understand what twisting is. Twisting is a necessary condition for yarn formation. Short fibers can be made into yarns with certain physical and mechanical properties through twisting; filaments often need to be twisted in order to increase the tightness between single filaments, facilitate processing, and improve fabric properties. Number of twists Twisting is to cause two cross-sections of parallel straight fiber slivers to rotate relative to each other. The number of relative rotations of the two cross-sections is called the number of twists. Twist Twist refers to the number of twists per unit length of yarn . Twist coefficient In actual production, the twist coefficient is of

Combing Process in Spinning

Image
Before processing cotton, wool, and silk fibers into fabrics, the process of removing impurities and short fibers in the fibers with a combing machine is called combing. The texture, washability and durability of the fabric produced through this process are greatly improved compared with carded fabrics. The following introduces the composition of the combing machine and the combing process. The kinematic coordination relationship of the main parts on the combing machine is indicated by a dial. The disc is mounted on the combing machine and rotates synchronously with the cylinder, which is generally called the indexing disc. The index plate is divided into 40 equal parts along the circumference, and each equal part is 9°, which becomes one index. The working cycle refers to the time interval between the combing cylinder of the intermittent combing machine corresponding to the two actions of combing the whiskers. That is: the first row of needles in the combing cylinder goes to the botto

Garment Dyeing-Special Dyeing Method In Textile

Image
Garment dyeing is a relatively special dyeing process for textiles and garments. Many people may not know much about this dyeing process. In the impression of most people, textile and clothing products are dyed in the fabric period, and garment dyeing is a dyeing process that breaks people’s cognitive limitations on textile dyeing. ​What is garment dyeing ​Garment dyeing means that dyeing the one not in the fabric type but in the garment type itself. The garment type mentioned above include socks, towels, sportswear, shirts, plush toys (without fillers), T-shirts, pants, bathrobes, handkerchiefs, bath mats, carpets, scarves, etc. The material of these garments can be wool, linen, silk and cotton of natural fibers. But most garments are made of cotton or a cotton-rich blends. Garment dyeing imparts vibrant colors to garments. The clothes such as denim garments, tops, sportswear and casual clothing with garment dyeing can provide a distinctive special effect. Garment dyeing method Garmen
