Surface Modification of Polyester Fibers to Produce an Operationally Stable Long-Term Effect

Resumo

Results from a study of surface modification of polyester fibers are reported. Hydrophobic and lipophobic effects were achieved by layering molecules of an anchoring polymer and a reactive F-containing surfactant. A long-term effect was produced by activating the polyester-fiber surface and chemically binding a modifier. The modification persisted at a high level after ten washings and dry cleanings.
