Classification of Yarn in Textile Manufacturing

Yarn is a continuous strand of textile fibres or filaments used to produce woven, knitted and other textile structures. Yarn can be classified in several ways according to fibre content, manufacturing method, structure and end use.

1. Classification by Fibre Form

Spun Yarn

Spun yarn is produced by assembling and twisting staple fibres together. Cotton, wool and staple polyester yarns are common examples.

Filament Yarn

Filament yarn is made from continuous filaments. It may contain one filament or multiple filaments grouped together.

2. Classification by Yarn Structure

Single Yarn

Single yarn is formed from one strand of fibres or filaments. It is used directly in many weaving and knitting applications.

Ply Yarn

Ply yarn is produced by twisting two or more single yarns together. This can improve balance, strength or appearance depending on construction.

Cabled Yarn

Cabled yarn is produced by twisting multiple plied yarns together. It is used for specialised applications requiring particular structural properties.

3. Classification by Manufacturing or Appearance

  • Ring-spun yarn: Produced through a ring spinning system.
  • Rotor-spun yarn: Produced through open-end rotor spinning.
  • Compact yarn: Produced using a spinning arrangement designed to reduce the spinning triangle and improve yarn characteristics.
  • Textured yarn: Filament yarn modified to introduce bulk, stretch or surface texture.
  • Fancy yarn: Yarn designed with special visual or structural effects.

Yarn count is used to express yarn fineness or linear density. Learn the relationship between linear density and yarn measurement in our guide to yarn count and sliver. The raw material also affects yarn properties; see classification of textile fibres.

Frequently Asked Questions

What are the two basic forms of yarn?

Spun yarn and filament yarn are two major forms based on fibre form.

What is ply yarn?

Ply yarn is made by twisting two or more single yarns together.

What is textured yarn?

Textured yarn is a filament yarn modified to provide properties such as bulk or stretch.

Conclusion

Yarn classification helps textile professionals select suitable yarn structures for different fabric constructions and end uses. Fibre type, spinning method and yarn structure all influence final product performance.
