Viscose Rayon is discovered by C.F. Cross and E.J. Bevan in 1891. It was discovered in UK. It is one of the oldest man made filament. We know that, viscose rayon is produced from the wood which contains cellulose for this reason it is called regenerated cellulosic fiber. It is produced by a spinning process.
The raw materials of the viscose rayon are prepared in the coagulated bath. Then the liquid solution is send to the spinneret through the spinning nozzle by high pressure. Spinneret contains about 12 to 90 hole which diameter is 0.5 to 0.1mm through which liquid is passed.
Spinning Bath Composition of Viscose Rayon: Following chemical solvents are contain in a spinning bath of viscose rayon.
H2SO4 : 10%
Na2SO4 : 18%
Glucose : 02%
ZnSO4 : 01%
Water : 69%
Above composition is calculated on 100%. Viscose rayon is one of the important manmade fibers. So, we should have bast knowledge about viscose rayon.
