Improving the coloration/dyeability of polyolefin fibres
POLYOLEFIN FIBRES: STRUCTURE, PROPERTIES AND INDUSTRIAL APPLICATIONS, 2ND EDITION, pp. 359β388.
An overview of polyolefin fibre characteristics pertinent to dyeing properties is given. Dye fibre interactions are briefly discussed and the role of fibre morphology on dye retention is briefly explained. The use of conventional dyeing techniques with commercial dyes including acid, direct, vat, sculpture, azoic, disperse, and solvent-soluble dyes on polyolefins is reviewed. Fibre modification including the use of polymeric and low molecular weight additives, copolymerization and grafting, polyblending, nanoparticle infusion, supercritical fluids, and chemical surface treatment to improve the dyeability of polyolefins is examined. Fibre modification may be the key in achieving commercially acceptable dyeings on polyolefins; however, recent advances in the dyeing of unmodified polyolefin fibres also show promise and merit further investigation.
