What are cut resistant gloves made of？

Engineering a cut-resistant glove begins at the fiber level, choosing from a multiple of fiber types and attributes. These fibers are combined, or spun, into different yarn constructions, which are then knit into a glove shell or fabric liner. Knit gloves typicaly receive a palm coating, while glove liners are integrated into a glove that is sewn together from multiple fabric components.

Each of these building blocks are specifcally designed to create a glove that is not only cut resistant, but suited to the wide variety of tasks and trades performed in environments with high-cut hazards.

1.CUT-RESISTANT FIBERS

The basic building block of a cut-resistant glove or glove liner is the fiber. Fibers can be man-made, such as nylon orpolyester - or they can be natural, such as cotton or wool. They also vary in weight and thickness, and can be thinner thana human hair. For cut-resistant gloves, there are two main types of fbers - staple fibers and flament fibers.

Staple Fibers

As shown in Fig 2.1, these fibers are usually twisted from shorter fiber bundles to form continuous long fibers. They have a “fluffy” feel, giving a warm sensation. They can absorb liquids and perform well in high - temperature environments. DuPont™ Kevlar® is a man - made staple fiber; cotton and wool are natural ones.

Filament Fibers

As shown in Fig 2.2, these fibers start as high - viscosity liquids, usually melted from pellets. The liquid is then extruded or drawn into long, smooth fibers. They have a slick surface, a cooler touch, absorb liquids on the surface, and are more lubricious than staple fibers. Nylon and stainless steel are filament fibers.

Many synthetic fibers have been developed to enhance cut - resistant performance. One example is ultra - high molecular weight polyethylene (UHMWPE), commonly referred to as high - performance polyethylene, or HPPE. Another example is DuPont™ Kevlar®. It boasts excellent cut and heat resistance, offering users additional advantages. The following table compares several different fibers found in cut - resistant gloves and liners.

2.YARN ENGINEERING

Yarns are created by winding multiple fbers together on winding machines. The yarn fibers can all be similiar, or they can be a blend of fbers each with diferent properties. Cut-resistant yarns are engineered by blending several different fibersutilizing different winding arrangements (twist, wrap, helix, etc.), to create a yarn with specifc properties - cut levelstretch, comfort, thickness, etc.

Figure 3.1 is an example of an engineered yarn with multiple fbers. Inthis example the glass fber core provides high strength, wound ina helix shape to improve flexibility. It is wrapped with HPPE fber,which adds comfort and improves cut resistance, and spandex is wound along the length of the yarn to provide stretch and enhanceft of the glove.

During the winding process, engineers can precisely set the windingtension on the fibers, which can give the overall yarn structure theability to 'roll' with a sharp edge or blade, increasing cut resistanceeven further.

Engineered yarns have revolutionized the feld of cut-resistantgloves, and opened the door to a world of possibilities. Historicallycut-resistant gloves were bulky, with poor dexterity, and often hadlow cut resistance. With today's engineered yarns, gloves with high cut resistance can be thin, comfortable, and have high dexterity as well.

3.KNIT/WEAVE STRUCTURE

Cut-resistant engineering yarns are knitted into glove shells or woven into linings. Different knitting/weaving techniques enhance comfort, flexibility, touch, and resistance (cut, puncture, abrasion).

Gauge

Cut-resistant gloves are classified by "yarn density" (textile term). For fabrics: stitches per inch (sewing machine) → finished fabric stitches. For knitted gloves: stitches per inch (vertical yarn bundles).

In Figs 4.1-4.2: Thick yarns = lower density (e.g., 7/10); fine yarns = higher density (e.g., 15/18). Low-gauge (thick yarn) gloves: heavier, bulkier (suitable for cold work/low flexibility needs). High-gauge (fine yarn) gloves: better flexibility/touch (suitable for precision tasks).

An important fact: High-stitch-count fine-yarn gloves offer limited cut protection. To cut effectively at high counts, gloves need advanced engineering yarns, mixing fibers to maximize strength, hardness, comfort & elasticity.

4.COATING

Most knitted gloves undergo coating in the final assembly. This involves a dipping process: gloves pass through a trough filled with heated liquid chemicals (e.g., latex). They’re then cleaned, surface - treated, and dried, resulting in a specialized coating for enhanced grip in various applications.

Many coating compounds exist, each advantageous in specific environments. Table 2 compares four common ones, highlighting their features. Beyond compounds, coatings have different surface finishes that boost grip when contacting diverse liquids/surfaces. Table 3 emphasizes ideal uses of coating types and finishes.

Understand coating chemistry and finishes to choose proper gloves. For example, foamed latex coatings offer excellent grip in oily/wet conditions, suiting workplaces with oil/chemical exposure. Remember, good grip is key to preventing workplace accidents.
