The principles of spinning are exactly the same now as when the task was performed by hand. The fibres are first ‘carded’ – arranged parallel to one another – by working them between two parallel moving surfaces faced with sharp points. Next they may be combed to remove short fibres, then fed into machines with rollers which draw out the fibres, making the yarn finer, and introducing a twist which holds the fibres together.
A very intense twist induces a kink in the yarn, as in crepe materials. Yarns may also be twisted together to produce a stronger, thicker thread – as in two-ply or three-ply knitting wool. Blended-fibre yarns may be made by spinning together fibres from different sources, mixing wool with polyester fibre, for example, to produce a better combination of warmth, strength and ease of washing.
Finally, the finished yarn is wound onto a bobbin, ready for dispatch.
