Effect of Laundering on Bending Properties of Plain-Knitted Fabrics

Abstract

This work investigates thechanges inbending properties in laundering of plain weft-knit s lk fabrics, as compared with cotton and polyester. The effects of variations of linear density and stitch density of fabric samples on bending properties due to repeated laundering areexamined. It is shown that both bending rigidity and hysteresis of the various yarns how different behaviour of the fibres in laundering. Silk is characterized by higher flexibility for bending inboth principal directions than cotton and polyester, in laundering. Differences between technical f ce and technical back bending are also shown. Linear density of silk yarns affects bending rigidity more than cotton.
