Abstract:

The surface chemical composition, hydrophilicity, and microstructure of wool fabrics before and after UV irradiation were characterized by surface property measurements. The results showed that during UV irradiation, cystine, disulfide bonds with hydrophobicity and nonpolar C-C bonds were partially dissociated, and the surface hydroxyls, nitrogen-containing groups, and C-O bonds increased, improving the hydrophilicity of wool fabrics, which was further confirmed by the decreased static water contact angle and increased capillary effect of UV irradiated wool fabrics. Moreover, the surface morphology and crystal structure of wool fibers hardly changed, but the roughness increased slightly in the chemical etching resulting from low-power UV irradiation within short time. Based on the above-described effects induced by UV irradiation on surface physical and chemical properties of wool fabrics, this method is conducive to woolen dyeing and finishing.
