Rayon is moisture absorbent (more so than cotton), breathable, comfortable to wear, and easily dyed in vivid colors. It does not build up static electricity, nor will it pill unless the fabric is made from short, low-twist yarns.
Certain qualities such as fineness, length, color and appearance determine the end use and value of wool. Fineness largely determines whether the wool is used in a suit, sweater, blanket or in a pair of socks.
Kapok/Capok fibre is one of the natural cellulosic fibres which grow on the kapok plant. It has a hollow body and a sealed tail, which are desirable features of candidates for functional textiles of this nature. However, the low volume weight of kapok is (specific density 0.29g/cm3), and the short length and smooth surface of the fibres, causing poor inter-fibre cohesion, have prevented kapok from being processed by modern spinning machines.
Coir or coconut fibre belongs to the group of hard structural fibres. It is an important commercial product obtained from the husk of the coconut. Industries based on coir have developed in many coconut producing countries especially India, Tanzania, Kenya, Bangladesh, Burma, Thailand, Sri Lanka, Nigeria, Ghana etc.
Fiber is a hair-like strand of material. It is flexible and can be spun or twisted for weaving, braiding, knotting, crocheting, etc. to make desired products. Fibres can be obtained in natural form from plants and animals as well as in synthetic form. Man-made or synthetic fibres are either made up of chemicals or by processing natural fibres to create new fibre structures/properties.
