A STUDY OF THE EFFECTS OF CHEMICALS ON THE STRENGTHS OF NYLON AND DACRON PARACHUTE FABRICS

摘要

The effect of certain organic solvents and solutions of inorganic substances on the strength of nylon and Dacron parachute fabrics was investigated. The fabrics were exposed to each of the reagents and then aged under different conditions for a. period of six months. Breaking strength tests were made on the fabrics at month¬ly intervals. For each testing condition, the concentration of reagent, ageing tem¬perature, and ageing condition were varied.nIt was found that in general, an increase in concentration, temperature, or time gave higher strength losses of both nylon and Dacron fabrics.
