Effects of Laundering and Water Temperature on the Properties of Silk and Silk-blend Knitted Fabrics

Abstract

The objective of this work was to review the properties of selected specialty protein fiber knit fabrics suitable for everyday wear. Selected properties (dimensional stability to laundering, mass, thickness, and stitches per centimeter) of three commercially available fabrics were measured when new and after each laundering cycle (1—6). The silk and silk-blend fabrics achieved dimensional stability by six laundering cycles. Fabric properties differed with the number of laundering cycles, fabric color, and fabric type. Although water temperature affected the pattern of change of some properties, it had no overall effect on properties of the stabilized fabrics. However, examination of new and washed fabric using scanning electron microscopy suggested fibrillation and degradation of silk fibers may be affected by laundering. © 2010, SAGE Publications.
