Color Change as a Predictor of Strength Loss in PFD Cover Fabrics
The fabric covers of many wearable personal flotation devices (PFDs) currently on the market are subject to rapid fading and loss of strength when exposed to light. The result of this rapid degradation may be loss of flotation protection for the wearer. This research evaluates the relationship between color change and loss of breaking strength in six PFD cover fabrics and explores the possibility of using color change to predict strength loss of selected PFD covers. Regression models were developed for each fabric and the models were used to predict the level of color change at which the fabric would fail to meet the U. S. Coast Guard minimum strength requirement for covers of wearable PFDs.
