چکیده [English]

Modifying polyester spacer fabric by β-cyclodextrin produces a new product with outstanding characteristics. Citric acid is used as a crosslinking agent for improvement of durability of this material in textile fabrics. In this research different concentrations of citric acid and β-cyclodextrin were applied on a 3D fabric and some properties including weight change, weight of moisture residue, water absorption time, chromic ion and reactive dye absorptions were studied. Furthermore, the morphology of fabric surface has been examined by SEM and its chemical structure has been elucidated by FT-IR. The washing durability of the modified product has been also studied after 10 washing cycles. The results show that increasing the concentration of citric acid and β-cyclodextrin leads to higher stability of the modified fabrics.
