Abstract:

The wool fabric was finished with self-made wool keratin solution, and reasonable finishing process parameters were selected by orthogonal experiments. The result indicate that the optimal finishing process of wool fabric was that the dosage of wool keatin solution was 15% (o.w.f), the processing temperature was 75℃, the processing time was 60 min and liquor ratio was 1:25. The performance of before and after the finishing of wool fabric was compared, the felting shrinkage of finishing wool fabric was decreased from 17.85% to 4.1%, the wrinkle recovery angle was increased from144.2 ° to 215 ° , respectively. Meanwhile the breaking strength was improved and breaking elongation was decreased slightly, and the wool fabric shaping effect is improved.

Key words: shaping, felting shrinkage, wrinkle recovery, mechanical property
