Abstract
Abstract The objective of the work was the preliminary experimental investigation of cut-resistant materials including a biomimetic perspective. The effects of the cutting were expressed as static and dynamic cut resistance of the following materials: knitted fabrics, woven fabrics, continuously coated knitted fabrics, and dot-coated knitted fabrics. The cutting process gives rise to frictional forces, but the current test methods for cut-resistant gloves are not designed to measure them. Therefore additionally, the cut resistance of the material was evaluated using a modified procedure based on the standard EN 1082-1, taking into consideration grip strength tests to assess if there is a potential correlation between cut resistance and anti-slip properties.

One way of preventing hand injury is the use of gloves that are fit for purpose in protective and ergonomic terms [1,2,3]
Except for some specialist protective devices, cut-resistant gloves are usually manufactured from p-aramid yarns (Kevlar®, Kevlar® Kleen®, Kevlar® Plus®, and Kevlar® Armor from DuPont; Twaron® and Twaron® Premium Line from Teijin) or core-spun yarns, with cores made of stainless steel or cut-resistant textile yarns and with sheaths made of textile yarns, polyethylene yarns (Dyneema® from DSM; Spectra®, Spectra® Guard®, and Spectra® Guard® CX from Honeywell), glass fibers, a combination of the above, as well as from cotton, polyamide, polyester, elastane, and Lycra fibers [5,6,7,8]
The presented static and dynamic cut resistance results reveal high variability in the performance of commercially available materials used in protective gloves against mechanical hazards
Summary
One way of preventing hand injury is the use of gloves that are fit for purpose in protective and ergonomic terms [1,2,3]. To impart anti-slip properties and facilitate the gripping of smooth and slippery objects, the palmar or both palmar and dorsal aspects of gloves may be coated with a continuous layer of polymer, usually polyvinyl chloride, polyurethane, silicone, nitrile rubber, or natural rubber. Such treatment improves the functional properties of gloves and enhances their mechanical resistance [9,10,11,12]
