Mechanical Properties of Yarns Dyed by Pigments

摘要

Furutani et al. [1-3] developed a technology for constructing trial fabrics. This technology consists of the dyeing technology realizing low cost and short term production, and minimizing loss of yarn and amount of drainage. Recently, an apparatus for dyeing with pigments were newly developed, in which the dyeing term was shortened by one -ninth, and the amount of drainage was reduced by one-tenth by the new apparatus. In this study, the mechanical properties of the dyed yarn with pigments by the new apparatus were investigated. The characteristics of yarns dyed with pigments were within the ±4σ of regular yarn group and there was no difference from the yarns dyed with dye stuffs if the concentration of binder was not beyond 10%. Therefore, it makes clear that dyed yarn by using the new apparatus can be utilized for trial fabrics.
