摘要

Needle puncture injuries present a critical occupational hazard for medical and security personnel due to the risk of bloodborne pathogen transmission. Protective gloves must therefore balance needle resistance, flexibility, and wearer comfort. This study introduces a new testing approach combining purpose-designed cylindrical fixtures engineered to replicate the geometry of human fingers with high-speed imaging for detailed analysis of perforation mechanisms. By providing a test configuration closer to real glove-use conditions, this method offers improved relevance for the design of protective multilayer textile systems. Three commercially available gloves (A, B, and C) with distinct protective architectures were evaluated: a stainless-steel/HDPE knit with a nitrile coating (A), synthetic leather with a stainless-steel weave (B), and resin plate reinforcements combined with a nylon knit (C). These were evaluated alongside newly developed multilayer gloves integrating double-weft 3D woven fabrics and shear-thickening-fluid (STF)-treated knits. By synergistically combining these established technologies into a single hybrid architecture, this study addresses the complex trade-off between high-level puncture resistance and flexibility. Commercial gloves A and B exhibited two main perforation mechanisms: initial needle-tip penetration followed by bevel-driven cutting, with maximum resistances of 5.8 N and 7.2 N, respectively. In contrast, glove C, which incorporates resin plate-like rigid elements, failed predominantly through brittle fracture and did not improve performance with a single layer of this innovative fabric (5 N). The newly developed double-weft 3D woven glove achieved the highest puncture resistance, reaching 10 N, corresponding to a 38% improvement relative to the best commercial glove. This enhanced resistance resulted from combined needle-trapping effects and increased yarn-to-yarn friction. However, the increased thickness and basis weight of the multilayer structure reduced its overall performance when evaluated through a criterion performance factor that incorporates thickness and basis weight, potentially leading to wearer discomfort. This work identifies key design parameters, including yarn selection, weave architecture, and inter-layer friction, and provides a quantitative basis for optimizing protective gloves to minimize mass and maximize flexibility without compromising needle puncture resistance.
