WebRayon 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. WebRayon, developed in France at the end of the nineteenth century, was the first “synthetic” fiber. It is not strictly a synthetic material because the cellulose polymer remains intact throughout the processing of the raw material, high-purity wood pulp.
