What is twisting technology?
The process of combining yarn is the preparatory process of yarn twisting or yarn doubling. However, two or more yarns are twisted, i. h The result is a yarn with higher strength, greater regularity, special color combination and special structure. Twisted yarn is produced from a single yarn in two steps: First, several yarns are brought together on a spinning machinet and then twisted together on a spinning machine.
The weavingThe g-process is the first stage and the twisting process is the second stage. When using a double twister or bar twister with three or more yarns to produce twisted yarn, the process of gathering is essential. This applies to two strands of yarn. There are two process lines that can be used in double twisting: Firstly, the classic method of double twisting is used. The second method is to use two single yarns that are wound and unwound on the double stock of the yarn roller assembly.
What is the use of a twisting machine?
Double twisting The machine is a kind of twisting equipment, which can realize one twist and two twists, and the twisting efficiency is compared to the conventional twine equipmentarmor doubled. By increasing the volume, ten thousand meters without connection, the twisting quality is greatly improved, low floor , particularly suitable for operation.
Characteristics of double twisting machine:High performance, high degree of mechanical and electrical integration, low energy consumption , high quality, convenient operation. Large volume and high yield. The double lathe has a fully automatic computer control system to ensure good positioning accuracy and running stability. Use high quality parts, low loss, long service life. Special roller design, avoid yarn winding, improve yarn quality. PLC operation, frequency conversion, stepless speed control, adapting to a variety of process needs, low maintenance costs.
Working principle
The double twisting machine can twist two or more single strands of yarn by twistingstick together into yarn and improve the performance of the original yarn to meet the needs of customers.
Possible defects
The main defects are generally weak twist, strong twist and no twist
What is the effect of the twist?
The experiment in the textile factory shows that the speed of the twine can be increased by 10%. This is due to the fact that the two yarns are balanced and stressed equally , when the parallel rollers are assembled. As a result, higher productivity is achieved.
Therefore, these benefits brought about by parallel winding are of vital importance, indicating that the parallel winding process cannot be aborted. It is better to consider the merits of a particular situation before making a decision.
What are the benefits of the Twister machine exercise?
1.The spindleTwo turns per revolution can be achieved, so the performance is high.
2. Make the coil in large rolls directly, saving one winding operation.
3. No steel collar wire ring, the ingot speed is not limited by the speed of the wire ring, reduce yarn oil.
4. Fewer processes, big roll, can improve labor productivity.
What materials can be twisted?
Application: low-elasticity polyester yarn, high-elasticity nylon yarn twisting. A chemical fiber filament made of thermoplastic synthetic fiber with permanent non-linear crimp, fluffy and elastic. Yarn can be used to make knitted outerwear, but can also be used to weave strong socks, underwear, sportswear, gloves and other knitted fabrics.
Application of double lathes in textile industryThe traditional Me Mechanical Twisting Machine
Due to der limitations of the speed, forming effect and maintenance of traditional mechanical forming, many spinning machine manufacturing companies have devoted themselves to the research and development of electronic forming twisting machines in recent years. Due to the limitations of shape control accuracy, anti-folding algorithm and other problems, the equipment actually put on the market is not very mature. The electric servoform control system of Sanacer products has been sold in large quantities in the market and achieves good economic and social benefits.
The traditional twisting machine uses only one motor as the power applied to the spindle, winding shaft and the cross coil is distributed ndulum rod by the kite belt drive mechanism and the gear mechanism. Mainly mechanical transmission, firm and durable, relatively low technical threshold, are the main characteristics of the traditionalTwisting machine.
Double lathe in the electric age
With the development of control technology, the purely mechanical transmission system can be replaced with a multi-motor transmission system to realize the optimization of machines and applications. The continuous development of modern electric control technology can achieve:
The three-phase induction motor is driven by the frequency converter to realize stepless speed control, which can control the spindle speed and winding speed. Separate control of spindle speed and winding speed makes it easier to control the rotation of the yarn, and the winding speed can be adjusted without a pole, which is more advantageous to control power consumption.
The permanent magnet synchronous servomotor is equipped with a high-precision encoder, which is controlled by the servo driver wird to enable fast start and stop and high-precision positioning, and which can be used to control the horizontal swing rod. The reverse swing rod servo control can realize the yarn angle and winding movement can be adjusted arbitrarily, but it can also control the stacking of yarns into a certain shape to match the needs of subsequent processing.
What\'s the difference between spinning and twisting?
A spinning frame is a machine that splices yarns together. It usually consists of a yarn splicing machine, a drawing machine and a fabric shrinking machine. It binds yarn to fabric and can change the structure and strength of the fabric.
Double twister refers to the machine that twists yarn into fabric, which usually consists of a yarn twister, a fabric tensioner, and a fabric shrinking machine. It twists yarn to fabric &nd can change the structure and strength of the fabric.
The difference between the two ways is that a spinning mill combines the yarn into a fabric, while a double lathe twists the yarn into a fabric. A spinning mill can produce thicker cloth, while a double lathe can produce thinner cloth. In addition, spinning can change the structural strength of the fabric, while double twisting can change the elasticity and strength of the fabric
DW7051H Laboratory Twisting Machine
