Yarn processing varies depending on materials used and what the end-product will be. They include:

 

Winding and assembly winding

This process is the merging of different yarns together to achieve a required thickness, usually prior to the further processes listed below.

 

Ring twisting

This uses a ring twister, which comprises a frame, spindles, roller and creel.

The untwisted fibre passes through a thread guide to the spindle and is then threaded through a small ring, called a traveller. This is what gives the ring twisting process its name.

Ring twisters can process any type of yarn, but are especially suited to delicate or very thin fibres.

 

Two-for-one-twisting

For this process, each mechanical spindle gives the yarn two twists with each single revolution. Yarn is unwound from a stationery pot, receiving its first turn within the spindle rotor, and its second within the yarn balloon.

This method increases the yarn’s strength and smoothness, while reducing the material cost by superior coverage of the yarn by volume.

It is used to produce fibres for:

  • the automotive, aerospace and agriculture sectors
  • packaging
  • transport
  • geotextiles
  • body armour
  • sports equipment
  • household materials
  • insulation
  • hoses

 

Doubling

This process involves merging and twisting single yarns into thickened yarns.

This process is used to manufacture thicker ropes and slings.

 

Multi-folding

Also known as plying, this process twists together two or more single fibres to make the resulting yarn strong and balanced. The result is plied yarn.

The ply count, for example 2-ply or 4-ply, refers to the number of strands of fibre within the yarn.
