Glycols of suitable composition is added to the spinning bath in the manufacture of rayon as “fiber forming aids” which imparts additional strength to the fibre. PEG 3000 is mostly recommended for this purpose. PEG 3000 if added to starch-based sizing agents facilitates the penetration of the size liquors into the thread and improves the smoothness. Dusting is prevented and viscosity of the liquor is reduced. Desizing is considerably helped due to complete solubility of the products. Glycols impart to the fibres a temporary antistatic finish and can also be used as base products for the manufacture of permanent antistatic¬†agents.
