Detection of Micro-Holes and Tears in Disposable Nitrile Gloves

  • Description:
    Objective: Development of a method to detect micro-holes/tears in disposable nitrile gloves. Methods: Tears of varying size were made in partially inflated nitrile gloves using 21, 22, 26s, 30, and 33 gauge 2-point style stainless steel needles. The lengths of these tears were measured using an Aven Mighty Scope of 500x magnification and with Microviewer software. The Frazier air permeability tester (FAPT) attachments were designed to create a holding compartment for glove materials, the Glove and Air Vacuum (GAV) dome. Gloves were loaded into the dome in one of two modes. The first used a glove piece of at least 2.5-inches in diameter loaded into an adapter. The dome was attached to the air permeability tester and the loaded adapter affixed on top. A 6.5-7 in-water vacuum was applied by the FAPT and 50 mL of water poured into the adapter. For the whole glove mode, the whole glove was placed into the GAV dome that is then attached to the FAPT at a vacuum of 11- 12 in-water before 600 mL of water is added. In both modes the vacuum was held for 90 seconds and the amount of water penetrating through the glove material was weighed and a flow rate calculated. Results: All punctures resulted in tears in the glove material. The method currently has a sensitivity of 131.6 +/- 0.01 um tear and flow rates of 2.48 +/- 0.4 uL/min for glove pieces, 28.15 +/- 2 uL/min for whole-glove palm, and 0.250 +/- 0.01 uL/min for whole-glove finger regions with potential as a qualitative method for smaller holes. Conclusions: The developed GAV dome method shows promise as a quantitative and qualitative technique to detect microholes/ tears in whole or pieces of disposable gloves.
