The Effect of Combined Atmospheric Plasma/UV Treatments on Improving the Durability of Flame Retardants Applied to Cotton.

ABSTRACT: Application of a combined atmospheric plasma/UV laser to cotton fabrics impregnated with selected non-durable flame retardants (FRs) has shown evidence of covalent grafting of the latter species on to cotton fibre surfaces. As a result, an increase in their durability to water-soaking for 30 min at 40 °C has been recorded. Based on previous research plasma gases comprising Ar^80%/CO₂^20% or N₂^80%/O₂^20% were used to pre-expose cotton fabric prior to or after FR impregnation to promote the formation of radical species and increased -COOH groups on surface cellulosic chains, which would encourage formation of FR-cellulose bonds.
