The hand performance of black silk yarns dyed via vegetable color dyeing

Abstract

The mechanical characteristics and the hand performances of black silk yarns dyed via vegetable color dyeing were discussed. The silk yarns were dyed with six black dyes extracted from different plants according to Japanese traditional dyeing method. The hand performances of six silk yarns were evaluated using the paired comparison method and were compared with the measured mechanical properties. The hand performances and mechanical properties of the yarn were influenced by the dyestuff used, and the changes in hand performances and the bending characteristics showed the similar tendency when the dyeing procedure was repeated.
