Cotton can be defined as a soft, furry plant fibre being extracted from the cotton plant. Cotton is made up of staple fibre that grows in a ball or protective case. Cotton is a widely used fibre that is used all over the world for different purposes. Cloth factories use this staple fibre for producing shirts, sarees, socks, towels, blankets, medical purposes, and other medical or cosmetic products.


What is Spinning?

Spinning is the process of binding together drawn-out strands of fibres to form a yarn. It is a major process used by the textile industries. It is the manufacturing process for creating polymer fibres. Some of the different types of spinners used in the textile industries are Ring, Rotor, Air Jet. 

The polymer is first converted into a fluid state. A thermoplastic polymer is just melted. The others may be treated chemically or dissolved in a solvent to form thermoplastic derivatives. The fluid polymer is made to pass through the spinneret. The polymer becomes cool to turn into a rubber-like structure and then solidifies. 


Types of Spinning

There are four different types of spinning:

  • Dry Spinning

The type of spinning used for fibre forming substances in solution is called Dry Spinning. A polymer is not drizzled by any chemical reaction or dilution. But it is solidified by evaporating the solvent in a stream of inert gas or air. The process that is used for the production of triacetate, acetate, vinyon, acrylic, etc. is termed as Dry Spinning. 

  • Wet Spinning

The process used for fibre forming substances dissolved in a solvent is called the Wet Spinning. This is an old process used for spinning. This method is termed as being ‘wet’ because the solution is directly extruded into the precipitating liquid. This old method of Wet Spinning is used to produce acrylic, rayon, modacrylic, spandex, etc.

  • Melt Spinning

When the fibre forming substance is melted in a process for extrusion through the spinneret and solidified directly by cooling, it is called Melt Spinning. This method is used to produce nylon, olefin, saran, sulfur, etc.

  • Gel Spinning

When the polymer is not in the true liquid state during extrusion, that method is called the Gel Spinning. This process is used to obtain high strength properties of the fibre.


What is the Yarn?

Yarn can be termed as a long continuous interlock of fibres that are suitable for the production of textiles, knitting, weaving, embroidery etc. Yarn is produced from a group of filament or staple fibres that are twisted together. 

The Processing of cotton involves the following steps:

Preparatory Processes → Spinning → Weaving → Finishing


How is Cotton Manufactured from the Yarn?

Spinning is the most vital and significant stage of processing textile products. In this method of spinning, the extracted fibres are made into yarn and are used in the production of textiles. The thread is a type of yarn intended for sewing, knitting, weaving, embroidery, etc. The obtained plant fibre has to go through several stages before the spinning of cotton yarns to remove the impurities, namely - Blending, cleaning, opening to finally draw the desired thickness. 


Cotton Yarn Spinning Process

Cotton Yarn Spinning

The initial state of textile product processing is known as the spinning process of the cotton yarn. When the yarns are produced from the extracted fibres, that process is called Spinning. Here, in this process - 

  • Twisting of the cotton strands together to form yarn takes place 

  • The yarn is placed on the rings of the spinning frame and is then passed through several sets of rollers, which are rotating at a successively higher speed.

  • The yarn is rolled by the rollers and wounded upon the desired bobbins.

  • This is the final stage of spinning the cotton yarn, in which drafting, twisting, and winding of the yarn are all finished in one operation.


Weaving of Cotton

When the two sets of yarn are interlaced so that they cross each other at the right angles, it is called the Weaving of Cotton. This process is completed either manually or by the machines.


Finishing of Cotton

The process in which the woven cloth is converted into useful material is known as the Finishing of Cotton. The final textile material that comes out is then treated with bleach and dyes to enrich its quality.
