    摘要: A barrier fabric composite is provided which comprises:i) a textile fabric comprising a front surface, a back surface, interstices within said fabric, and a determinable interstitial volume;ii) a liquid barrier enhancing thermoplastic within said interstices and on said back surface, filling at least 50% of said interstitial volume; andiii) a liquid barrier enhancing plastic coating, on the back surface of said thermoplastic, having a higher melting point or glass transition temperature (T.sub.g) than said thermoplastic, and capable of withstanding temperatures of at least 350.degree. F.The composite can be prepared bya) forming a film and fabric composite having a determinable interstitial volume by simultaneously feeding a thermoplastic film and a textile fabric between first and second rollers, wherein said film is heated to a plastic state and forced into interstices in the backside of said fabric by said first roller so as to fill at least 50% of the interstitial volume;b) applying to the backside of the composite resulting from step a) a liquid barrier enhancing plastic coating having a higher melting point or glass transition temperature (T.sub.g ) than said thermoplastic, and capable of withstanding temperatures of at least 350.degree. F; andc) drying said liquid barrier enhancing plastic coating.

    摘要: A process for the removal or reduction of residual trimethyl amine odor resulting from the quaternization of a halogen containing precursor with trimethyl amine. Odor reduction is achieved by reacting the residual trimethyl amine with at least an equivalent amount of methyl chloride at a temperature of at least 50.degree. C. for a period of time to convert substantially all of the trimethyl amine to tetramethyl ammonium chloride.
