Abstract

Inverse gas chromatography (IGC) has been successfully used for comparative characterization of the surface properties of alkaline-scoured and bioscoured cotton samples in fibrous form. Under appropriate standard conditions the dispersion component (γ _s ^d ) of surface tension and the electron-acceptor (K _A) and electron-donor ( K _D) constants were determined for characterizing the surface properties of raw, alkaline-scoured and pectinase-scoured cotton. The dispersion component of surface tension increased slightly with increasing hydrophilicity of the surfaces (raw: 39.0 mJ/m², bioscoured: 40.0 mJ/m² , alkaline scoured: 41.7 mJ/m², at 30°C), indicating that the wax removal that occurred is somewhat higher in alkaline scouring than in bioscouring. The γ _s ^d values decreased continuously with increasing measurement temperature in the range of 30—70°C (raw: 32.0 mJ/m², bioscoured: 33.2 mJ/m², alkaline scoured: 35.9 mJ/m², at 70°C). Polar probes were not retained on raw cotton at all. The surface of the alkaline-scoured and bioscoured cotton samples was predominantly basic in character: K _D /K _A 6.8 and 8.2, respectively, where K _A and K _D were calculated from the ΔG _A ^ab at 30°C. Despite the weight loss difference (3.2% and 0.7% for alkaline and bioscouring, respectively) and the residual pectin in bioscoured cotton, the results show that the acid—base character of the surface of the alkaline and pectinase-scoured samples is very similar.
