STABILITY AGAINST STABBING AND BULGING OF KNITTED MATERIALS FOR THE MANUFACTURE OF PROTECTIVE GLOVES

Abstract

The study aims to investigate the resistance of knitted materials made from meta-aramid (MA) fibers, para-aramid (pA) fibers, and high-molecular-weight polyethylene (pE) yarns to penetration by a needle and deformation under a ball, produced on a two-bed flat knitting machine of 8th class, type glove automatic PA-8. 34 / ІМ №2, 2025 НАУКОВИЙ ПОШУК Methodology. The study involved methods of analysis and synthesis of scientific and technical literature, as well as an experimental method for testing the developed samples of knitted materials for their resistance to needle penetration according to EN 388:2019 and ball bulging following PN-EN ISO 3379:2015. The testing was carried out using a WDW-5ES model electronic testing machine. Results. For the tests, knitted material samples were produced on a two-bed flat knitting machine of 8th class (glove automatic PA-8) using yarns based on meta-aramid fibers, high-molecular-weight polyethylene, and para-aramid fibers. One-layer and two-layer specimens were prepared from these materials. The resistance of the developed knitted materials to needle penetration and ball bulging was determined. Scientific novelty. The factors influencing the resistance to needle penetration and ball bulging of the developed knitted material samples and their corresponding packages were identified. The compliance of the obtained knitted materials with the regulatory requirements for hand protection products against mechanical damage was established. Practical significance. For the manufacture of seamless individual hand protection equipment against mechanical damage and flame exposure, it is proposed to use a two-layer package of knitted materials, where one layer is made from flame-resistant yarn based on meta-aramid fibers, and the other from para-aramid or high-molecular-weight polyethylene yarns to ensure resistance to mechanical damage.
