Scanning electron micrograph (SEM) of Viscose Fibres. This highly synthesized natural cellulose (Gossypium herbaceum) is from a hair product, the fibres of which are used for hair enhancement and thickening for people with thinning hair and who are balding. This product is a manufactured fibre of the Viscose group that started life as a natural source of cellulose, in this case cotton. The process involves regenerating a manufactured fibre from the dissolved original natural cellulose. The original natural source has a twisted ribbon-like structure. The transformed fibre, as shown in this micrograph, is an extruded, serrated manufactured fibre of synthetic form. Magification x1690 (x415 at 10cm wide).
