Why are the fibers obtained from plants or animals converted into yarns?

Answer: The process where the cotton wool are drawn out and being twisted. This process brings all the fibre together to form a yarn. The following steps are used in the preparing fabrics: (i) Obtaining fibre (ii) Spinning where you obtain the yarns, Gives 2 sets of yarns thus, yarns are woven to make a fabric.

Why are fibres converted into yarns?

Because filaments, such as silk and the synthetic fibres, have extreme length, they can be made into yarn without the spinning operation necessary for the shorter staple fibres. When grouped together in a loose, continuous rope without twist, synthetic filaments are called tow.
