Abstract
Since the pyrolysis of polymers has continuous cycle, acrylonitrile (AN) was polymerized on the surface of the PET fabrics using an inductively coupled glow discharge system to promote crosslinking at the fabric surface to protect further pyrolysis. We investigated the flammability characteristic of plasma polymerized acrylonitrile (PPAN) deposited fabric, and dyeability. The chemical structure of PPAN was different from that of AN by molecular recombination, and the thermal analysis indicated that the PPAN was crosslinked. PPAN on the fabric results in a char which insulates the bulk from the heat of flame zone, and prevents the producing of flammable volatile fragment, and caused an increase in LOI value and decrease in burnins rate. Owing to the formation of unsaturated groups such as C=C and C=N and the second generation polar group C=0, dyeability of treated fabrics was improved.
