Dyeing as-spun polypropylene fibres with disperse dyes using periodic technology

The major possibility of dyeing PP fibres medium hues with disperse dyes using periodic technology was demonstrated. It was found that dyeing as-spun PP fibres ensures diffusion of the dye inside the fibre material. Use of Neonol AF 9/6 nonionogenic wetting agent during dyeing increases the amount of dye sorbed by PP fibre material. Translated from Khimicheskie Volokna, No. 1, pp. 24-26, January-February, 2008.
