Additives Used for Polyethylene Fibre Production

The use of additives in PE fibres can be divided into three categories  

Coloration through polymer modification or dye-receptor addition before extrusion or by adding dye to the melt. Films, fibres, and tapes are coloured almost exclusively with concentrate granules, the amount of which varies between 1 and 10% in correlation with the depth of the shade required, thickness and opacity, fastness to light, rubbing, and washing.
