Abstract or Summary
  • A procedure is described for analyzing the nitrogen content of durable press cotton fabric at the rate of 20 samples per hour using the Technicon Kjeldahl Auto Analyzer equipped with a continuous digestor. This method was as good as or better than conventional micro -Kjeldahl technique s. Durable press cotton fabric from the earlier W103 Western Regional study was laundered for 0, 1, 12, 24, 36 and 48 times at 140 F followed by a 104 F rinse and tumble drying. An additional sample at each laundry level was both steam pressed and laundered. The fabric was then analyzed for total percent add-on of finishes, total nitrogen, durable press rating, wrinkle recovery angle, bursting strength and Elmendorf tear resistance. Percent add-on and decreases in nitrogen content due to extraction with perchloroethylene, ethanol, water and 0. 1 N HC1 were also determined. Steam pressing in addition to laundering did not significantly affect any of the physical properties studied. Bursting strength did not change significantly during laundering. Tear resistance decreased significantly through 36 launderings. Significant decreases occurred during the first laundering and up to the twelfth laundering for percent add-on, durable press rating and wrinkle recovery angles. Total nitrogen content showed a significant quadratic effect on durable press ratings with increased launderings. This was related only to the 0. 1 N HC1 extractable nitrogen containing fraction. Major decreases in other nitrogen containing and most percent add-on fractions occurred only during the first laundering. No other relationships were shown between nitrogen content and observed physical properties.
