Simultaneous influence of ageing and softener on mechanical properties of knitted textiles during life cycle of garment

Purpose The purpose of this paper is to examine the influence of ageing and the use of fabric softener during the life cycle of knitted fabrics. Design/methodology/approach The low‐stress mechanical properties were evaluated by means of the Kawabata evaluation system for fabric (KES‐F) and universal surface tester (UST) revealing that the tensile, shear, bending, compression and surface properties were altered by both ageing during the wash cycles and the use of fabric softener. Findings Machine laundering leaves fabrics with an uncomfortable hand due to the removal of finishes and the harsh mechanical action of laundering, and results in the change in mechanical properties of the fabrics. Originality/value The paper identifies the critical mechanical parameters which are influenced by ageing and the use of fabric softeners during life cycle of garments.
