Viscose rayon 

Rayon, artificial textile material composed of regenerated and purified cellulose derived from plant sources. Rayon is a manufactured regenerated cellulosic fiber derived from wood pulp. Rayon is typically made of wood from eucalyptus, spruce, and pine trees, but can also be made from cotton or bamboo. Typical rayon called rayon, viscose rayon, viscose. Rayon made using the cuprammonium process can be labeled cupra, cupro, or cupra rayon. 

Developed in the late 19th century as a substitute for silk, rayon was the first man-made fibre. Rayon is described as a regenerated fibre because the cellulose, obtained from soft woods or from the short fibres (linters) that adhere to cottonseeds, is converted to a liquid compound, squeezed through tiny holes in a device called a spinnerette, and then converted back to cellulose in the form of fibre. 

The first commercially available synthetic fibre, viscose rayon, was developed around 1910 and by the 1920s had made its mark as reinforcement material for tyres and, subsequently, other mechanical rubber goods such as drive belts, conveyors and hoses. Its relatively high uniformity, tenacity and modulus (at least when kept dry within a rubber casing), combined with good temperature resistance, proved ideal for the fast emerging automotive and industrial equipment markets. At a much later stage of its lifecycle, other properties of viscose such as its good absorbency and suitability for processing by paper industry-type wet laying techniques contributed to its role as one of the earliest and most successful fibres used for nonwoven processing, especially in disposable cleaning and hygiene end-uses.
