Certain marks referenced herein may be common-law or registered trademarks of third parties affiliated or unaffiliated with the applicant or the assignee. Use of these marks is for providing an enabling disclosure by way of example and shall not be construed to limit the scope of the claimed subject matter to material associated with such marks.
Hockey players recognize the need for safety equipment, such as helmets, shoulder pads, elbow pads, gloves, pelvic protectors, shin guards, mouth guards and neck guards. Neck guards may help protect against broken necks, however, when a player falls or is pushed to the ice when skating at high speed, the player can end up sliding head-first into the wall around the rink, a goal post or another player, possibly resulting in head and neck injuries, or feet-first or sideways, possibly resulting in broken ankles, legs, arms or pelvis. There is little that a player in that situation can do to slow or stop the slide.
Prior-art attempts at ice traction and safety in other contexts include the following patent publications, each of which is incorporated by reference:

According to www.interweave.com/article/weaving/what-is-terry-cloth/, “Terry-cloth is a pile weave, which means that there are uncut loops woven into the fabric on one or both sides, which are raised above the groundcloth. Pile weaves can have cut or uncut loops, woven either weft-wise or warp-wise, but terry-cloth is always warp-wise, hence the need for supplemental warps! The first terry-cloth towels were handwoven from silk, made in France in 1841. The name ‘terry’ came from the French word ‘tirer,’ which means ‘to pull out or through.’ This clearly referred to the supplemental warps, which were ‘pulled out’ to create the distinctive loops that make terry-cloth so absorbent and soft. Throughout the mid-1800s, several British and United States manufacturers began mass-producing woolen and then cotton terry-cloth. Both industrially and in the home, terry-cloth is usually woven on a loom with two warp beams: one for the groundcloth warp threads, and one for the pile warp.”

Some embodiments of the present invention include a method and apparatus for inhibiting sliding on ice; for example, garments such as hockey jerseys and/or hockey pants made at least partially of a material, such as microfiber cloth, that inhibits sliding when the hockey player falls to the ice at speed wearing such garments. In some embodiments, a terry-cloth fabric such as described in U.S. Pat. No. 7,044,173 is used to make the slide-inhibiting garment of the present invention. In some embodiments, a terry-cloth fabric such as described in United States Patent Publication 2004/0224121 is used to make the slide-inhibiting garment of the present invention, with the micro-fiber pile yarns on the outer face of the garment and the cotton pile yarns on the inner face for a more comfortable feel against the skin of the hockey player. In some embodiments, a knit fabric using microfiber is used for the present invention (such as described in U.S. Pat. No. 7,465,683 that issued to McMurray on Dec. 16, 2008 with the title “Functional double-faced performance warp knit fabric, method of manufacturing, and products made there from,” and which is incorporated herein by reference. In other embodiments, knit fabrics (such as, for example, tricot knit, micro-knit, micro-denier knits (e.g., using fibers of less than one denier (also called microfibers)), open knits, mesh knit, warp knit, weft knit, air knits, “porthole” mesh, pin-hole mesh and the like) made of microfibers are used. Weft knitting is a method of forming a fabric in which the loops are made in horizontal way from a single yarn and intermeshing of loops take place in a circular or flat form on across-wise basis. Warp knitting is a method of forming a fabric in which the loops are made in vertical way along the length of the fabric from each warp yarns and intermeshing of loops take place in a flat form of length-wise basis.
In some embodiments, the pile loops on the terry-cloth outer face of the garment are each cut open to expose more fiber ends to the ice, while the pile loops on the inner face of the garment are uncut in order to provide a more comfortable feel to the player's skin. In some embodiments, the inner face of the garment has no pile loops, and only the outer face has micro-fiber pile structures, and in some such embodiments, pile loops on the outer face of the garment are each cut open to expose more fiber ends to the ice.

In some embodiments, fabrics that include nanofibers are used in the present invention for applications that justify the cost delta. In some embodiments, mass-market commercial hockey garments or other sports apparel of the present invention will use nano-fiber anti-slide fabrics in the future.
Many youth and adults are injured every year due to sliding on ice or snow into a hard or immovable object while engaged in sports activities. As an example, in ice hockey players are checked or trip and fall at a speed that results in a slide into the boards, goalposts or another player. This can result in concussions and other head injuries, broken bones, or spinal-column injuries that can result in paralysis or death.
The present invention seeks to eliminate or minimize these and other injuries that otherwise occur. In some embodiments, the present invention provides ice-sports or snow-sports apparel, uniforms or gear made for the purpose of decreasing the severity of collisions with boards, goal posts, people, trees, fences, and the like. This is accomplished by manufacturing or treating clothing and sports gear with materials that inhibit the duration and speed of sliding after falling on ice or snow. In some embodiments, the present invention includes a safety garment that includes a gripping surface applied to an exterior or optionally to the interior surface of the article of clothing so that when the inside non-slip surface contacts with the existing wearer's conventional existing clothing, the inside non-slip surface prevents slippage between the anti-slip clothing and the wearer's underlying conventional or existing clothing.
