How is yarn made? Dec 06, 2023

Yarns can be made of staple fibres by several techniques. The method used is dependent upon such factors as the economic implications, the fibres to be used and desired properties of the yarn to be produced. Rings pinning is the oldest and most wide spread technique. Open end spinning is another major method. The development of short fibres, or staple, into yarn, when started in terms of basic manufacturing processes, is as follows:

Carding

Combing

Drafting

Twisting

Winding


As the fibres pass through these processes, they are successively formed into lap, sliver, roving and finally yarn. Here the manufacturing operation in which these stages occur:

Lap to card sliver by the carding process
Card sliver to comb sliver by the combing process (if the fibre is to be combed)
Sliver to roving by the drafting, or drawing process
Yarn reeled on bobbins, spools or cones by the winding process
