What Is Yarn Spinning Processes? How Is it Done?
Yarn spinning is the process which converts the fibre into the yarn, which is later used in manufacturing various types of fabrics. Spinning is a vital part of the textile manufacturing cycle as it is through this process that the end nature of the fabric is decided. Different types of spinning methods are used to make different types of yarns. There are various methods through which a fibre can be spinned to be used as a fibre to make different types of textile products. You can get top deals on various types of yarns which are made with various types of fabrics for the buyers to choose from.
The aim of spinning process is to convert the single strands of fibre into workable and continuous length of yarn spinning processes. This yarn is later used to make different types of fabrics. The spinning process is different for both natural and man made fabrics, and therefore there are various types of spinning processes.
List Of All Types Of Spinning Processes
Spinning process is a highly vital process in textile manufacturing and aims to make the fibres more compliable and easy to work with. There are various type of fibres which are available in the market and are spun to make yarns of different types. These yarn spinning processes are suitable for being used in textile production. Following given is a list of all types of fibre spinning methods which are commonly practiced in the textile sector:
1. Ring Spinning
Ring spinning is one of the most popular types of spinning processes and is also the oldest form of spinning processes in textile industry. Ring spinning converts short length and raw fibres into continuous yarns with the help of various machines. Cotton and wool fibres are commonly produced from ring spinning process. However, ring spinning process is costly because of its slower production rate and requirement of other additional processes.
2. Hollow Spindle Spinning
In this type of spinning process, the parallel fibre’s drafted strands are wrapped either by the surface fibres or by a continuous filament. This wrapping filament used in the spinning process adds strength to the yarn which is produced from the wrap spinning process. the yarn spinning processes produced from hollow spindle spinning process have a diverse range of application and are of superior quality.
3. Combined Systems
Combined spinning process is known to produce superior quality yarn and was originally invented to combine the benefits of ring method and hollow spindle method. It was later discovered that two hollow spindles can be installed in the structure. This resulted in production of different types of yarns which had various benefits. Combined spinning method is used to manufacture yarn spinning processes which have a stable structure and a special effect on them.
4. Doubling System
Doubling system is a type fo textile spinning technique which facilitates simultaneous feeding of two or more yarns which can be fed independently at controlled speed. The feed of the fibre in this type of spinning process can be uniform, fluctuating or intermittent, as required. Doubling system produces spiral or marl type yarn spinning processes when the feed material in the system is in the yarn form itself. This method is popular amongst spinners who wish to produce dimple and yet fancy structures. The most significant term in weaving technology is yarn sizing.
5. Open End Spinning
Open end spinning is a yarn spinning processes which eliminates the use of spindle. Open end spinning uses a rotor in which various fibres can be collected altogether and then drawn off as a yarn. The rotor rotation gives a twisting force in open end spinning. There are two commonly used techniques in open end spinning, which are rotor and friction. Keep reading further to know about all types of yarn spinning processes methods practiced in the textile industry.
5.1 Rotor System
In rotor system, each fibre is carried on to the rotor on an air stream and is laid in contact with the collecting surface. This is done so that the collecting fibres are arranged around the circumference. Moreover as the fibres are drawn off, the twist is imparted by the rotor, resulting in creation of Yarn sizing Process. Rotor spinning is ideal for spinning short staple fibres and is one of the most popular open end spinning technique.
5.2 Friction System
Frictional system uses two frictional rollers to spin the fibres into yarns and is another highly popular type of open end spinning technique. The fibres are delivered to the rollers in silver for and are opened by the opening roller. These opened fibred are later blown off to the opening roller by air current and are transported to nip area with the help of two fractional drums rotating in the same direction.
5.3 Vortex Spinning
Vortex is a relatively new form of yarn spinning processes technology in the open end spinning. This is one of the most advanced form of technology in yarn spinning processes which has gained immense popularity in past years. Vortex spinning is a advanced form of air jet spinning and has the ability to spin carded cotton yarns at a high speed, therefore ensuring efficient results.
6. Air Jet Spinning
In air jet spinning, the drafted fibre strands have to go through one or two air nozzles which are situated in the middle of the front drafting roller and take up system. Highly pressured air is pushed inside the nozzles, which results in swirling airstreams inside these nozzles. This causes insertion of false twist into the drafted fibre and the edge fibre wraps on the surface of core stand, therefore resulting in creation of yarn.
7. Chenille Yarn System
The chenille yarn system is a highly popular method of producing chenille yarn which creates two ends in the end of each unit. This result in effect yarn being wrapped around a triangular shaped gauge at the top, which narrows towards the base, allowing the coils of effect yarn to slide downside on the cutting knife. The effect length is dependent on the width of the bottom gauge.
Electro statically flocking ground yarn along with loose fibres results in creation of yarn which has a chenille effect. This type of spinning is known as flocking process. The loose fibres and ground yarns used in flocking are charged with opposite electrostatic charges to ensure that the electro static flocking is strong. Moreover, the loose fibres have the same electrostatic charge and repel each other, therefore, providing food fibre separation to the end product.
9. Mock Chenille
In mock chenille spinning, a mock chenille effect is achieved by plying two gimp, loose or boucle yarns with dense effects. The yarn spinning processes made with this spinning technique does not has chenille look of its own but the fabric made from this yarn resembles a chenille like effect. This is because of a large number of small loops present in the surface of the fabric.
Different Types Of Yarn Spinning processes Techniques
There are various different types of spinning techniques which are practiced in the textile sector. This articled has highlighted all types of fabric spinning methods which are practiced in the textile sector. Each type of spinning technique results in a unique type of yarn which has its own distinguished characteristics and traits. Yarn manufacturers use various types of spinning techniques to produce different type of yarn spinning processes. Moreover, the choice of spinning technique largely depends on the fibre being used for the process and the desired end results.
