Abstract

The influence of wool fiber pretreatment with aqueous solutions of sodium laurylsulphonate, alkylphenolethoxylate or
benzyl alcohol on mechanical properties and colour changes of wool fiber occurring during UV irradiation were
examined. The changes of wool fiber properties were estimated using measurements of tensile strength, elongation at
breake, yellowness index and lightness. The data have shown a higher relative tensile strength of pretreated with
nonionic surfactant and irradiated wool fiber sample comparing to ones pretreated with anionic surfactant. Abrasion
testing results have shown that the resistance of irradiated wool fabric to abrasion were related with yellowness index
values.
