Surface photografting modification with
maleic anhydride (MAn) under UV irradiation in associa-
tion with a post reaction with triethanolamine has been
used to improve the flame retardancy of polyamide6.6
(PA6.6) fabric in this study. The effects of irradiation time
and monomer concentration on the fabric surface grafting
were investigated. The flame retardancy and thermal
decomposition behavior of the samples were characterized
by limiting oxygen index test (LOI), thermogravimetric
analysis (TGA), and differential scanning calorimetric
(DSC), and the results indicate that flame retardancy of
the treated PA6.6 fabric samples has been significantly
improved. The chemical structures of the treated samples’
surface were characterized by attenuated total reflection
infrared spectroscopy (ATR-FTIR), and the possible photo-
chemical mechanisms were discussed. It is suggested that
this could be the first time to use photografting technology
to enhance the flame retardancy of PA6.6 fabric.
