A synthetic alternative to waterfowl down for use as an insulator in military clothing and sleeping bags was developed by Albany International Research Co. under a previous contract with U.S. Army Natick R, D and E Center. The objective of the subject contract has been to demonstrate that two distinctly different forms of the previously developed alternative insulator can be manufactured. These forms are 1 a bonded staple-fiber batt and 2 a batt of spread continuous-filament tow. Manufacturing processes have been developed andor adapted to permit the continuous production of high performance, synthetic alternatives to down in each of these two forms and 100 square yards of each have been delivered to the Natick Center. A series of laboratory measurements have been made to assess the performance of each insulator form. The data obtained show that the bonded staple-fiber batt is equivalent to waterfowl down in terms of insulating efficiency and is superior to down on the basis of wetting resistance.
