hewlett packard 6890 gas chromatography mass spectroscopy machine the only significant finding was an increase in the peak heights of the laboratory hood samples which generally indicates a greater mass of the chemical being detected since it is known that this amine will adsorb carbon dioxide from the air and react to form an insoluble carbamate it is believed that only the carbamate is being detected due to the reaction rate it is difficult to isolate the pure starting material by this technique while techniques exist that should allow one to determine the percentage of amine that was converted to carbamate these techniques were not investigated the following example shows how exposure of the amine to air affects the strength of the treated fabric examples 1 and 2 were repeated 2 times each except the amine in each case was intentionally exposed to the air for 2 hours before the treatment was performed the results of this exposure to carbon dioxide in the air are shown in table 2 table 2 shows that exposing duomeen u00ae cd to the ambient air generally increases the strength of the chemically treated product which for the purposes of the present invention adversely affects the pilling tendency of the fabric by making it harder for the pill ball to break away from the fabric however the fabric treated with isotridecyloxypropyl 1 3 diaminopropane does not show significant changes in its strength characteristic and thus exposure to the carbon dioxide in the ambient air does not detrimentally.
