IMPROVEMENT OF THERMAL STABILITY OF TEXTILE FIBERS
Abstract
Improvements on, or alternatives to, the acrylonitrile melt retarding process were sought by three different approaches. First, trying to crosslink with halo-phosphorous compounds, and thus to combine melt and flame retardation holds excellent promise for an alternative process of meltproofing, but has not been found practical for flameproofing. Second, coating by inter facial polymerization. Time was not sufficient to elaborate all the many angles of this group of reactions. It was established that the basic method can be applied on a laboratory scale and does lead to meltproofing. An elaboration of this approach with a view to achieving simulta neous flame retardation is highly indicated. Finally, reactivating melt-retarding coatings for the anchorage of flameretarding agents. Promising leads uncovered were the copolymerization of acrylonitrile with methacryloylchloride, though the subsequent steps of anchoring a suitable chemical to the active acid chloride site has not been worked out.
