SLIP-RESISTANT MATERIAL
A slip-resistant material is disclosed. According to embodiments of the disclosure, the slip-resistant material can partially conform to the body's contours during physical activity to eliminate, or at least to reduce, slippage. The slip-resistant material can be a coated lightweight, synthetic hexagonal mesh. The slip-resistant material can also be a base wicking fabric with soft nodules formed on it. The slip-resistant material can also be a base wicking fabric with a top layer comprising nodules and pores. The slip-resistant material can also be a combination of a base wicking fabric with a polymer-based thread. The embodiments of the disclosure are safe to be worn directly against skin and are comfortable, breathable, and durable. The embodiments of the disclosure can be used as a liner between an article and the wearer's skin to hold the article in place during movement.
This application claims benefit of U.S. Provisional Patent Application No. 62/426,155, filed Nov. 23, 2016, which is hereby incorporated by reference in its entirety.
FIELD OF THE DISCLOSUREThis relates generally to a slip-resistant material, and more particularly, to a slip-resistant material that can be used as a liner between an article and the wearer's skin to hold the article in place during movement.
BACKGROUNDMany slip-resistant materials are presently available for holding objects in place, such as shelf liners found in home improvement stores. Shelf liners may be made of foam polyvinyl chloride (PVC) that can hold an object in place by compressing and partially conforming to the anatomy of the object when the object is placed on top of the shelf liner. These typical slip-resistant materials, however, may not be safe to wear directly against a person's skin or do not provide the necessary comfort, breathability, and durability for athletic or everyday activities.
Other materials, such as spandex, nylon, or polyester, are safe to be worn directly against a person's skin but tend to slip during athletic activity, causing discomfort from friction. This is particularly true for athletic shoes. During athletic activity, a shoe's fit shifts as multidirectional weight transfers occur, causing the foot to slip in its position. This micro-slippage results in inefficient energy transfer, and the friction generated creates painful blisters and reduces overall athletic performance. As the foot moves inside of the shoe, ground is lost and energy is wasted. Products such as TRUSOX™ attempt to prevent slippage in shoes by including tacky pads on both the inside and outside of socks. These tacky pads, however, are uncomfortable and can cause painful blisters.
Accordingly, there is a need for a slip-resistant material that not only can be safely worn directly against a person's skin, but also is comfortable, breathable, and durable for athletic and everyday activities.
SUMMARYThe disclosure relates to a lightweight, slip-resistant material that can be safely worn directly against a person's skin. When pressure is applied to the material, the material can compress, partially enveloping the body's contours and gripping the skin to prevent the material from slipping, or at least to reduce slippage. The material can be used as a liner to help keep an article in place during physical activity. The material can have gaps for enhanced breathability and be durable enough for physical activity. The material's properties can also act as a shock absorber during physical activity, further enhancing athletic performance.
Some embodiments of the disclosure relate to a soft, abrasion-resistant, non-absorbent, foam-like material that partially envelopes the contours of the wearer's skin, gripping and holding the material in place. According to some embodiments of the disclosure, the slip-resistant material can be created from a sheet of lightweight synthetic hexagonal mesh that can be dipped in a warm chemical bath that bonds to the mesh. The mesh can be made of lightweight fabric such as nylon, polyester, spandex, or a blend thereof. The coating can be a blend of silicone, polyurethane, ethylene-vinyl acetate (EVA), or thermoplastic elastomers that may not retain fluid, which can make the material easy to wash and air dry to prevent or reduce odor. The mesh design can allow for increased breathability, while the soft, foam-like coating can increase the coefficient of friction to prevent slippage. In some examples, the soft, foam-like coating can be hydrophilic (e.g., allows water to pass through). In this way, the soft, foam-like coating can allow wicking at the points of contact with the skin.
Some embodiments of the disclosure relate to a two-layer, slip-resistant material that can include soft nodules on a base fabric. The nodules can be placed on the base fabric at varying densities, with high-wear areas of the base fabric having a higher density of nodules than others. The base fabric can be a breathable wicking fabric. The base fabric can be a porous or mesh fabric. The nodules can be a blend of elastomers, such as silicone and neoprene, and lightweight, high-compression set foams, such as EVA and urethane. The nodules can be tiny, soft, lightweight, pressure-sensitive, and abrasion-resistant. In some examples, the nodules can be hydrophilic (e.g., allow water to pass through). In this way, the nodules can allow wicking at the points of contact with the skin. The nodules can be formed on a base fabric in a pyramid shape. The wide base of the nodules can ensure that the nodules are not ripped from the base fabric, and the narrow head of the nodules can increase sensitivity to pressure and response time and can enhance the overall comfort and feel of the material. The nodules' shape can also lengthen the reach of the pressure-sensitive material to the skin, and can improve breathability by increasing air circulation around the nodules and allowing sweat and water to reach the moisture-wicking fabric. During physical activity, the soft, flexible, pyramid-shaped nodules can reach out into the skin's negative space and fill where they are needed and compress where they are not. As the wearer's body moves during physical activity and the body swells with heat and pulses under the strain of exertion, the nodules can constantly compress or decompress to adapt to their changing environment and comfortably grip the surface of the skin. The resulting effect is a breathable fabric that can constantly react to maintain an enhanced fit.
Some embodiments of the disclosure relate to a two-layer, slip-resistant material that can include a top layer formed on a base fabric. The base fabric can be a breathable wicking fabric. The top layer and can be a blend of elastomers, such as silicone and neoprene, and lightweight, high-compression set foams, such as EVA and urethane. The top layer can include nodules on the side opposite the base fabric. The top layer can also include pores. The nodules can have the same properties as the nodules described above. The pores of the top layer can allow sweat and water to reach the moisture-wicking fabric. In some examples, the top layer can be hydrophilic (e.g., allows water to pass through). In this way, the top layer can allow wicking at the points of contact with the skin.
Some embodiments of the disclosure relate to a combination of a lightweight, pressure-sensitive, polymer-based thread or cord and a base fabric. The base fabric can be a breathable wicking fabric, such as nylon, polyester, spandex, or a blend thereof. The base fabric can be a porous or mesh fabric. The polymer-based thread can be a blend of elastomers and lightweight, high-compression set foams. The polymer-based thread can be manufactured from traditional chemical and spinning processes for making synthetic fibers. The polymer-based thread can be 1 mm or less in diameter and can be knitted, weaved, or embroidered into the base fabric. The polymer-based thread can also be woven into the base fabric and then sheared to a specific length. In some examples, the polymer-based thread can be hydrophilic (e.g., allows water to pass through). In this way, the polymer-based thread can allow wicking at the points of contact with the skin. A knotting embroidery technique may also be employed to create small knots on the base fabric similar to the nodules described above. The combination of the base fabric and the polymer-based thread can result in a lightweight and breathable, slip-resistant material that can respond to the topography of the human body—compressing and decompressing—during physical activity.
