The optical wrinkle tester developed in this study
showed great potential for determining the dynamics
of a fabric to recover after wrinkling. After calibration,
the wrinkle recovery factors of the textile samples were
reliably and accurately measured, and the relaxation
characteristics and kinetic profiles of relaxation immediately
after spraying were assessed. The wrinkle recovery
factors after spraying came close to the wrinkle
recovery factors measured after ironing.
The efficiency of spraying with anti-wrinkle sprays
depends on the concentration of the active agent (the
vegetable oil) and on the chemical composition of the
triglycerides. Active agents, low in unsaturated fatty
acids, are more effective than those with a higher
degree of unsaturation.
