The Manufacture of Viscose Rayon Fibres

Although it is one of the earliest of man-made fibres, viscose rayon remains of great interest. This is because it is made from a renewable resource, and because the fibre-making process is so adaptable. Novel types have been made, and continue to be made, to meet the changing demands of the textile market. Recent developments include the new class of high-strength viscose fibres with tenacities of 25 to 28 cN /tex, the super-inflated cellulosic SI fibre which has a very high absorbency without containing any additives, the hollow circular cross-section fibre Viloft for blending with cotton or polyester, and a new generation of enhanced-dyeing fibres
