| Cut resistance |
High-strength para-aramid fibers provide strong resistance to cuts from sharp edges and sheet materials. |
Cut performance is commonly classified under ANSI/ISEA 105 levels A1–A9 or EN ISO 13997 levels A–F. The rating applies to the tested glove construction, not the fiber alone. |
A cut-resistant glove is not cut-proof. Blades, force, glove condition, fit, and exposure angle affect actual protection. |
| Heat resistance |
Kevlar fibers retain useful strength at elevated temperatures and do not readily melt like many thermoplastic fibers. |
EN 407 contact-heat testing uses exposure levels of 100°C, 250°C, 350°C, or 500°C for a specified time. The glove must be tested and labeled for the relevant level. |
Heat protection varies with fabric weight, lining, coating, seams, contact time, and moisture. Fiber heat resistance does not equal unlimited hand protection. |
| Flame behavior |
Aramid fibers are inherently flame resistant and generally do not melt and drip when exposed to flame. |
Flame performance should be verified through the applicable EN 407 or equivalent test results for the complete glove. |
Flame resistance does not protect against prolonged radiant heat, molten metal, or every type of thermal hazard. |
| Abrasion resistance |
Woven or knitted Kevlar can provide useful durability in handling and fabrication tasks. |
EN 388 abrasion ratings range from Level 1 to Level 4 under the older scale, with Level 4 representing the highest level in that scale. Newer test markings may use a performance value instead. |
Coatings, yarn blend, knit structure, and thickness can change abrasion performance significantly. |
| Puncture resistance |
Dense constructions may improve resistance to some puncturing objects. |
Puncture is separately tested under standards such as EN 388 and is reported independently from cut resistance. |
Kevlar cut resistance should not be treated as automatic protection from needles, nails, spikes, or hypodermic objects. |
| Tensile strength and tear resistance |
The fiber has high strength-to-weight performance, helping gloves withstand demanding handling applications. |
Actual glove strength depends on yarn size, weave or knit, stitching, coating, and construction. |
A strong fiber cannot prevent failure caused by worn seams, damaged coatings, snagging, or poor sizing. |
| Weight and dexterity |
Lightweight knitted designs can provide cut protection without the bulk of some heavy leather or multi-layer gloves. |
Dexterity is normally assessed as a separate performance characteristic, such as EN 388 dexterity levels 1–5. |
Thicker liners, coatings, and multiple layers generally reduce flexibility and tactile sensitivity. |
| Moisture and wet handling |
The fiber itself does not readily lose all of its strength when exposed to ordinary workplace moisture. |
Wet-grip performance is determined mainly by the palm coating, surface texture, and glove design. |
Uncoated textile gloves can absorb liquids, reduce grip, and provide limited protection against oils, solvents, and water. |
| Chemical exposure |
Kevlar can be suitable for selected industrial environments where mechanical and thermal hazards are the primary concern. |
Chemical resistance must be confirmed using permeation and degradation data for the specific chemical and glove material. |
Kevlar alone is not a universal chemical barrier. Some strong acids, alkalis, solvents, and oxidizing chemicals can damage aramid fibers. |
| Electrical safety |
Textile construction may be useful for mechanical protection in electrical work when used with an appropriate electrical-insulating system. |
Electrical protection requires gloves tested and marked to the relevant electrical standard and voltage class. |
Kevlar work gloves should not be assumed to provide protection from electric shock or arc flash unless specifically certified for that hazard. |
| Comfort and breathability |
Knitted constructions can be flexible and more breathable than fully coated or heavily layered alternatives. |
Comfort depends on glove gauge, liner, cuff design, ventilation, coating coverage, and correct sizing. |
Heat-resistant fibers do not necessarily keep hands cool; prolonged hot work can still cause heat stress and perspiration. |
| Cleaning and service life |
Many textile glove designs can be laundered when the care instructions permit, helping reduce replacement frequency. |
Cleaning temperature, detergent, drying method, and allowable cycles must follow the glove manufacturer’s instructions. |
Repeated washing, chemical contamination, abrasion, cuts, and heat exposure can reduce performance. Inspect gloves before every use. |
