Synthetic Fibres And Plastics Fabrics are made of fibres which are obtained from natural and artificial sources. Wool, silk, and cotton are a few examples of natural fibres and fibres like polyesters and terylene are a few examples of synthetic fibres. Natural Fibre The naturally occurring fibres that humans derive from plants or animals are known as natural fibres. Eg: cotton, wool, silk, etc. · Basic component of animal fibres is Protein Synthetic Fibre Fibres that are made or created by humans are known as synthetic or man-made fibres.
