Abstract
The present disclosure relates to an article comprising an antimicrobial-containing polymer fiber, yarn, or ply to inhibit the growth of live pathogens for the prevention of cross-contamination when touching a surface or object that would have had live pathogens on it and thus to prevent or reduce infection therefrom. The article may be used in combination with a textile such as a shoe, scrubs, bag, sweater, pants, or any other clothing and/or accessory to reduce the risk of infection and/or cross-contamination from handling such articles. The method of preventing or reducing contamination or cross-contamination and infection by employing these articles to secure textiles about a user is also disclosed.
Description
TECHNICAL FIELD

This disclosure is directed to an article that can be described as laces for footwear, a drawstring, a strap, or a belt having one or more antimicrobial-containing fibers, yarns or ply woven, knitted or braided into the article. The article is used to secure various textiles and prevent or reduce the cross-contamination of pathogenic microbes, such as bacteria, viruses, and fungi, that may arise from touching and handling such articles.


BACKGROUND

Throughout the day, a person can expect to adjust their clothing, or textiles, multiple times. This involves handling laces for footwear such as shoes or ankle braces, belts, drawstrings, straps, and many other articles used to secure clothing, footwear, hats, or textiles. This can lead to an increase in the spread of pathogenic microbes such as bacteria, viruses, and fungi and increases the risk of cross-contamination leading to infection. This is a significant problem, particularly for those traveling, working in healthcare facilities, food preparation facilities, schools, and any environment where the amount of and the spread of pathogenic microbes is high.


During manufacture, substances can be sprayed on clothing, shoes, and their shoelaces to preserve the items and prevent microbial growth during shipment. However, these topically applied substances are readily sloughed away when the footwear or clothing is worn, handled, or washed. Disinfectant sprays such as Lysol® or Microban® which claim to kill 99.9% of bacteria can be sprayed on textiles to prevent microbial growth, however these sprays are temporary and must be reapplied regularly. Also, according to the label, many of these spray or liquid disinfectants are intended to be applied to hard, non-porous surfaces and in order to be effective the article must be completely saturated with the sprayable disinfectant, whereas articles such as shoelaces have a flexible and/or soft, porous surface, typically an open weave textile.

DETAILED DESCRIPTION

Microbes, such as viruses and bacteria, come from many different sources. Some may come from particles expelled from a person via breathing, coughing, sneezing, or talking. Some microbes have the ability to cause infection, these are known as pathogenic microbes. Microbes eventually come to rest on a surface, for example, many are gravitationally motivated to fall downward. For example, these microbes may come to rest on the floor. Many pathogenic microbes can remain viable for extended periods of time on surfaces and create the opportunity for continued contamination and infection. Surfaces of textiles, for example, those surfaces about a person that reside below the elbows or lower are especially vulnerable to receiving such pathogenic microbes, for example, shoes, shoelaces, belts, drawstrings for pants, skirts, shorts, hoodies. Likewise, portions of textiles that are routinely handled by people, such as handles for bags, and lanyards are vulnerable to receiving such pathogenic microbes.


Because of gravity, many things, including microbes, land on shoes and shoelaces. In healthcare facilities this can mean dangerous pathogens on one's shoes and shoelaces. Since floors, carpets, alleyways, roads, bathrooms, kitchens, medical arenas, locker rooms and gyms are a collection point for bacteria, fungi, viruses, etc., walking or running across or contact with these surfaces stirs up microbes just above the ground and they can deposit on and contaminate textiles. Washing the textile may remove some or all of the microbes; however, this is temporary as the next time the textile is worn, they are subject to becoming contaminated again.


For example, using a shoe/shoe lace for illustration, a shoe wearer can start off with a new shoe, void of any microbes and after a day at work, in a hospital for example, it's loaded with microbes. They may not touch their shoes with their hands once they get home as they may just kick the shoes off when they walk in the door. But they'll ultimately end up touching the shoe and/or its laces in the next morning when they go to untie/tie their laces and put their shoes back on. These laces may be contaminated with live microbes after exposure from their previous day at work, in addition to other microbes grown during the night while the microbes were busy reproducing or multiplying. A shoe secured with shoelaces comprising antimicrobial agents, as disclosed and described herein, will prevent or reduce microbe growth on the antimicrobial-treated laces. Thus, the incorporation of antimicrobial agents in articles such as shoelaces will prevent or reduce microbial cross-contamination and therefore possible infection. Likewise, hands that are contaminated may cross-contaminate a textile article. The present disclosure provides for the reduction or elimination of such cross-contamination to a textile article by presenting an antimicrobial agent at a portion of the textile article surface.


Metal, such as copper, silver, and zinc have antimicrobial properties. These natural antimicrobials offer many advantages over currently used therapies. For example, many bacteria acquire resistance to antibiotics, however bacteria do not acquire resistance to the metal's antimicrobial activity. Copper metal, copper oxides and copper iodides have been incorporated into frequently handled non-textile surfaces in hospitals to prevent or reduce the spread of infection with some success.


In addition to antimicrobial metals, there are a plethora of organic antimicrobial compounds that can be incorporated into fibers, yarns, or ply. For example, triclosan can be incorporated into synthetic polymeric fibers during the melt-spin process.


The present disclosure provides for an article, such as a shoelace, prepared from fibers, yarns, or ply with a built-in antimicrobial agent. As opposed to a spray on or dye bath application surface coating, adding the antimicrobial into the polymer as its being melted during the fiber extrusion process places the antimicrobial permanently throughout the fibers, yarns, or ply rather just temporarily on the surface. As the fibers, yarns, or ply wear away due to abrasion, the antimicrobial agent is always exposed on the surface. In one example, inorganic antimicrobial agents are used for articles that can be or are intended to be washed repeatedly.


Often, in settings where people worry about the spread of pathogenic microbes, people can wash their hands many times each day, wear gloves, and use hand sanitizer. However, there are many potentially pathogenic microbes on items such as shoelaces, drawstrings, etc., that can be spread easily when handled by clean hands. In one example, increased spread of microbes, particularly pathogenic microbes, from handling infrequently or never washed articles such as shoelaces, belts, straps, drawstrings, etc. is reduced or eliminated by the present disclosure. By incorporating antimicrobial-containing fibers, the growth and therefore the spread of live microbes from these articles is reduced or eliminated, and thus the risk of infection is also reduced.


Copper, silver, zinc, salts thereof, and oxides thereof are known to inhibit the growth of bacteria, viruses, fungi, and other pathogenic microbes. For instance, copper has shown efficacy as an antimicrobial against E. coli, methicillin-resistant Staphylococcus aureus (MRSA), Clostridium difficile, influenza A virus, adenovirus, and various fungi. Copper is believed to elicit its antimicrobial effect via many mechanisms. Most importantly, increased copper levels within a cell causes oxidative stress that can lead to damage. Copper also compromises the integrity of a microbe's cell membrane, or viral coating in the case of a virus, and can lead to leakage of important nutrients required to keep the microbe alive. Copper can also bind to proteins and interfere with their essential function. Silver and zinc have also proven to be a powerful antimicrobial, via similar mechanisms particularly by interfering with the integrity of the cell membrane, or viral coating, and causing leakage of vital nutrients. Antimicrobial metals have many other potential mechanisms of action as antimicrobials, and they are not limited to disruption of membranes nor is the antimicrobial activity limited to the microbes listed here.


Non-limiting examples of organic antimicrobial agents that are effective against a wide range of pathogenic microbes. For example, triclosan, hexachlorophene, chitosan, poly(hexamethylene biguanide), quaternary ammonium salts such as alkyl trimethylammonium bromide, benzalkonium chloride, didecyldimethylammonium chloride, dimethyldioctylammonium chloride, and quaternium-24; N-halamines such as N-chloro-2,2,6,6-tetramethyl-4-piperidinyl methacrylate, and many others have long been used as disinfectants and antimicrobials. Some of these compounds are melt processable with various thermoplastics used to make fiber, yarn, or ply. By “melt processable”, it is intended that the antimicrobial maintain at least some antimicrobial activity after being melt processed with a thermoplastic.


The present disclosure incorporates antimicrobials, such as organic antimicrobials and inorganic antimicrobial including metals, such as copper, silver, and zinc, into frequently handled items, such as shoelaces, bag-straps, drawstrings, lanyards, and other articles that secure clothing or textiles. Another aspect of the present disclosure is providing these antimicrobial articles to textiles used or worn by healthcare providers and any other users who may be at a high risk of exposure to pathogenic microbes.
