Abstract:

Two improved types of nylon yarns 1 Type 330, 30 denier, a more UV radiation and heat resistant yarn and 2 Type 300, 30 denier, a higher strength than the conventional nylon yarn, were developed to be used in materials for personnelAND OTHER TYPE DECELERATORS. Cloth, woven of the 2 types of nylon yarn, in both natural and International Orange were exposed to 1 outdoor weathering, 2 accelerated aging and 3 a temperature of 300 F. Type 330 nylon cloth in natural color retained a very high percentage of strength under all 3 exposure conditions the Type 330, International Orange and the Type 300 in both natural and International Orange deteriorated at a very rapid rate after exposure to both outdoor weathering and accelerated aging. It was determined that the type of dye used to obtain the International Orange color, was the chief factor in strength loss of the dyed Type 330 cloth. Author
