Abstract. To increase the wrinkle resistant property of tussah silk fabric, the eco-friendly
crosslinking agents of citric acid (CA) was applied to tussah silk wrinkle resistant finishing process.
Tussah silk fabric was treated with a conventional pad-dry-cure method. The finishing effects of
tussah silk fabric including wrinkle recovery angle, whiteness and mechanical properties were
characterized. The finishing agents CA in the presence of catalyst of sodium monophosphate (SHP) as
well as the treatment conditions significantly affected the anti-wrinkle effects of treated tussah silk
fabrics. The treated fabric samples showed increased wrinkle resistant property. The retention rate of
breaking strength and whiteness of CA treatment tussah silk meet to the demands of the fabric
treatment.
