Biopolymer is a term used to describe an organic compound of high molecular-weight.
Fibres are elongated cells with pitted cell walls. Found in water-conducting tissue, xylem (transport tissue in vascular plants ) and food-conducting tissue, phloem (living tissue carries organic nutrients), along leaf veins and margins, and surrounding vascular bundles in stems.
Hopsacking is a course, open, basket-weave fabric. The name comes from the plain-weave hemp and jute fibre for sacking in which hops gathered. Made from cotton, wool, linen, rayon, silk, hemp, or jute, it has a somewhat rough texture and is quite durable and often bulky.

Natural fibres are any hair-like raw material directly obtainable through an animal, vegetable, or mineral source that can be convertible, after spinning, into yarns and then into woven cloth.
