  • Strength loss indicator for synthetic yarns
    Patent number: 7939128
    Abstract: A webbing formed of synthetic yarns having an indicator for indicating exposure to ultraviolet light which results in strength loss of said synthetic yarns. The strength loss indicator comprises a strip extending along at least a portion of the webbing. The strip includes a phosphorescent material that produces a glow when exposed to ultraviolet light. The phosphorescent material is adapted to lose its ability to produce a glow over time exposure to ultraviolet light. Advantageously, the ability to glow fades at a rate correlated to the rate of loss of tensile strength of said synthetic yarns due to ultraviolet light exposure to indicate the condition of the webbing.
