PYROLYSIS OF A COTTON/NYLON FABRIC
Abstract
An examination of gases evolved by organic solids as they are exposed to thermal radiation was undertaken. Gas chromatography was utilized for analyzing products evolved from an untreated 50 percent cotton, 50 percent nylon 66 fabric exposed to radiation derived from a carbon arc. The products were carried via helium gas through a dry ice - acetone trap into an adsorption chromatograph and analyzed. The condensate in the dry ice - acetone trap was analyzed on a Resoflex R-296 column. While the tarry substance on the cell window and fritted glass filter was identified utilizing infrared. A third fraction, collected in liquid nitrogen, was also analyzed by infrared techniques. The products characterized were carbon monoxide, carbon dioxide, hydrogen, nitrogen, methane, several polar organic components, and levoglucosan. It was found that the pyrolysis of cotton/nylon produce greater quantities of CO2 and N2 than were observed in the pyrolysis of cotton. Many aliphatic amines were detected in the products evolved from the cotton/nylon fabric.
