Abstract
In the current study, a novel wool dissolving system based on NaHSO3, azone and LKZ-610 (Trisubstituted organic phosphorus, an anti-shrink finishing agent for wool and cashmere) was prepared and employed to process wool fibers into keratin solution at 90°C for 7 hrs, where 65g wool fibers, 30g NaHSO3 and 5g azone were dissolved in 1L LKZ-610, resulting in high molecular weight keratin solution. The anti-pilling rating reached at Grade 4.5 with good hand when the cashmere fabric was treated for 50min at 50°C in the previously prepared wool keratin solution under the condition of 1:20 bath ratio, 8% owf keratin solution and 5% owf LKZ-610.
