Abstract
A new procedure for microscopical determination of the effects of certain flame-retardant finishes on polyester filaments is based on the solubility of polyester in 50% NaOH. Observations were made of solubilities of ultrathin cross sections of polyester filament from several blends of cotton/Kodel polyester and 100% Kodel polyester before and after treatment with tetrakis(hydroxymethyl)phosphonium chloride, urea, trimethylolmethylglycoluril, and poly(vinyl bromide) flame retardant. Protection from dissolution increased in proportion to the amount of poly(vinyl bromide) used in the treatment.
