Abstract
Treatments of cotton in the form of yarns and rovings with liquid ammonia are described. Smaller loss of strength as a result of prolonged heating at 160°C was found in these treated yarns. Since no strength changes were found in the fibers, it is concluded that this was due to a greater tendency of the ammonia-treated cotton to curl and crinkle, which increases the friction between the fibers in the yarn.Keywords
