Definitions

  • the present invention relates to a method for controlling bacteria, mold, mildew and related odors which frequently occur in areas where dampness and moisture are present as well as where bacteria can flourish.
  • Typical examples of such environments include floors and wall surfaces of hospitals, nursing homes, hotels, commercial kitchens, exercise facilities and the like.
  • the method of the present invention involves the usage of a non-woven antimicrobial material, located between a floor covering, such as carpet, and the flooring and surrounding areas.
  • the present invention also provides non-woven fabrics having antimicrobial properties.
  • antimicrobial carpets are known which are topically treated with minimal doses of antimicrobial agents. While these applications meet Government Standards for commercial carpets, namely Method GS-20, as the test for effectiveness, this test has inherent deficiencies. For one, by the nature of the test, minimal additions of antimicrobial agent have proven effective in the test; for another, the way the test is administered, topically treating the face fibers or the backing will pass the test and finally, the low dosage levels historically used in the industry have not translated in proven product performance to the end consumer and therefore, these have not been viewed as effective or as offering value added benefits.
  • Another disadvantage with topical treatments other than the minimal amount of agent that is employed is that the agent is readily removed, particularly by cleaning operations. The latter often effect a trade-off, however, because the cleaning operation can employ antimicrobial agents whose residue is left on and in the carpet for subsequent duty in killing the bacteria that is present. This too, can lead to erroneous evaluations of the initial treatment.
  • the antimicrobial agent migrates to the surface of the binder and onto the fibers, continuously until the supply is exhausted.
  • Such non-woven fabrics are useful in the manufacture of washing and wiping cloths, hospital gowns, sheets, pillow cases, and curtains, and as backing agents for garments, bed spreads and the like.
  • U.S. Pat. No. 4,769,268 relates to the stabilization of antimicrobial agents, thermoplastic compositions containing the same, and a method of melt processing such thermoplastic compositions.
  • the patent discloses that it is known to form fibers from the thermoplastic compositions and to utilize the fibers to form articles such as carpets.
  • U.S. Pat. No. 4,343,853 discloses two-face fabrics containing antimicrobial agents and a method for imparting antimicrobial characteristics to two-face fabrics.
  • the construction of the latter involves the formation of a face fabric, having no antimicrobial additives, and a backing fabric, having an antimicrobial additive incorporated therein.
  • the patent discloses and claims such fabrics and a method of imparting antibacterial characteristics to untreated yarns in a two-face fabric. Typical examples include the construction of athletic sweatshirts and of carpets.
  • the two fabrics are tied together in a conventional manner and one of the objects achieved is migration of the antimicrobial agent into the untreated, face fabric.
  • the patent states that growth of mildew and other odor forming bacteria is significantly decreased by the invention, as compared to other known approaches, where one face fabric is treated to protect against antimicrobial growth on the other.
  • an object of the present invention to provide a method for controlling biological attack from micro-organisms which come into contact with floors, floor coverings and wall surfaces.
  • the present invention provides a method for controlling the growth of micro-organisms in conjunction with construction of buildings comprising applying a non-woven fabric containing at least one antimicrobial agent to floor or wall surfaces where micro-organisms can reside; applying a covering thereover, the fabric forming a barrier between the surface and the covering, whereby passage of micro-organisms through the covering to the underlying surface is inhibited by the fabric.
  • the present invention also provides non-woven fabrics for controlling the growth of micro-organisms in buildings comprising from 50 to about 100 percent by weight of a synthetic fiber, containing at least one antimicrobial agent, in an amount of about 25 to about 50,000 parts by weight per million of the fiber and, from 0 to about 50 percent by weight of a synthetic fiber, devoid of antimicrobial agents, the non-woven fabric being employed to surfaces beneath subsequent covering materials.

  • Fig. 4 is a perspective view, partially broken away, depicting the use of the non-woven antimicrobial barrier fabric of the present invention, having been applied beneath stucco.
  • the present invention is directed toward a method for controlling the growth and spread of micro-organisms, including but not limited to various strains of bacteria, fungi, algae and related living contaminants which spread and cause disease, as well as mold, mildew, related odors and occasionally, staining of affected areas and surrounding surfaces.
  • micro-organisms including but not limited to various strains of bacteria, fungi, algae and related living contaminants which spread and cause disease, as well as mold, mildew, related odors and occasionally, staining of affected areas and surrounding surfaces.
  • dampness such as in basement areas, mold and mildew and the accompanying odor can be inhibited and virtually eliminated by treating the affected areas according to the present invention.
  • carpet is applied over floor surfaces, and occasionally some of the vertical wall surfaces, for reasons of aesthetics, sound barrier properties, comfort and safety, among others.
  • carpet can collect and house many micro-organisms, particularly due to spillage.
  • carpet is a covering, dampness and wetness are not readily removed.
  • the base or backing of the carpet becomes a breeding area for the various micro-organisms which can cause and spread disease as well as mold, mildew and the like.
  • carpet is typically applied to concrete floor surfaces in residential and commercial settings, the problem also exists over wooden flooring, various wall surfaces and virtually any surface onto which a covering can be applied. These surfaces include, without limitation, wallboard and floors behind and beneath tile; framework, sheathing, plywood and particle board used in construction behind stucco and other forms of exterior fascia; walls, behind wallpaper and other wall covering materials and substantially any other horizontal, vertical or sloping surfaces (roofs) where moisture can accumulate and/or bacteria, mold, fungus, mildew and the like can reside.
  • the method of this invention includes the use of a non-woven fabric comprising synthetic fibers.
  • the manufacture of non- woven fabric is well known and thus, does not require disclosure here.
  • the preferred fabric comprises 50 percent by weight rayon and 50 percent by weight polypropylene.
  • the polypropylene is, in turn, produced from antimicrobial fibers while the rayon is devoid of antimicrobial agents.
  • the fabric has a weight of approximately 0.5 to about 50 ounces per square yard, with ranges of from about 0.5 to 15 ounces per square yard being preferred and ranges of from about 0.5 to 5 ounces per square yard being most preferred.
  • the non-woven fabric can comprise 100 percent by weight of a single fiber type, such as polypropylene.
  • polyolef ins such as polyethylene and polymethyl pentene; polyesters; nylon; acrylics; acetates; and polyvinyl chlorides and any other typical fiber-forming polymeric materials.
  • polyolef ins such as polyethylene and polymethyl pentene; polyesters; nylon; acrylics; acetates; and polyvinyl chlorides and any other typical fiber-forming polymeric materials.
  • Still other polymeric materials suitable, but less preferred, as fibers for the present invention include acrylonitrile-butadiene- styrene terpolymer (ABS), polysulphone, polybutylene terephthalate (PBT) and polyurethane.
  • Amorphous polyolef ins such as polyethylene, polypropylene, and polymethyl pentene are generally most preferred because these fiber-forming polymers provide spaces or "zones" which are suitable for the deposition of antimicrobial agents within the fibers.
  • Crystalline polymers such as nylon and polyester, while capable of being used to the purposes of the present invention, generally provide less suitable environments in which to place the antimicrobial agents. Any polymeric fibers which include sufficient space or large enough "zones" to deposit the antimicrobial agents without deleteriously altering the molecular structure or physical properties of the antimicrobial agents are desirable.
  • useful fiber lengths can range from about 0.04 to about 6 inches, with about 0.75 to about 3 inches being preferred and from about 0.9 to about 2.1 inches being most preferred.
  • Useful fiber diameters can range from about 0.00011 to about 0.0038 inches, with about 0.0007 to about 0.0022 inches being preferred and from about 0.0007 to about 0.0014 inches being most preferred although broader ranges are not to be necessarily precluded. It is also customary to refer to the fiber yield, i.e., denier (determined by the weight in grams of a 9000 yard length), rather than diameter. Accordingly, useful deniers preferably range from about 0.04 to about 60 with about 2 to about 20 being preferred and from about 2 to 8 being most preferred.
  • Antimicrobial agents useful for practice of the present invention preferably are non-toxic and environmentally safe both during use and disposal. Most antimicrobial agents control the growth of organisms by penetrating the thin cell walls of the organism, thereby disrupting the metabolic function of the organism and ultimately killing the organism. However, non-toxic antimicrobial agents cannot successfully attack human and red-blooded animal cells, which have thick cell walls, thereby making these antimicrobial agents toxicologically safe in the dosage range indicated hereinbelow.
  • antimicrobial agents includes any substance which effectively protects the fibers, the carpet, related adhesives for the application of carpet and, the surfaces to which the carpet is applied from biological attack from organisms including, but not necessarily limited to, fungi, bacteria, mold, mildew, algae, and other thin-celled organisms.
  • an antimicrobial agent suitable for use in the present invention is a phenolic-based product with an extremely low toxicity level (LD 50 of 3000-5000 mg/kg at 100%) currently available from Microban Products Company of Huntersville, North Carolina, under the tradename "Microban B". "Microban” is believed to be a registered trademark owned by Microban
  • Microban B is a polymer additive engineered to provide a controlled migration to the surface of the product in which it is incorporated, providing long-term efficacy, as detailed hereinbelow.
  • Dosage rates for the addition of antimicrobial agents to the fibers employed in the present invention vary signi icantly depending upon the strength required to inhibit targeted bacteria, fungi, mold, mildew and the like and can be coordinated with the amount of antimicrobial-containing fibers employed in the non-woven fabric.
  • the effective dosage will vary from about 25 parts per million to about 50,000 parts per million (ppm) by weight per weight of the fibers, with 250 to about 25,000 ppm being preferred and 400 to 20,000 ppm being most preferred, although lesser or additional quantities may be used to achieve suitable efficacy.
  • a preferred amount is 5000 ppm of the foregoing antimicrobial agent in the polypropylene fiber.
  • the selection of any specific amount will depend upon the antimicrobial objective to be achieved.
  • the preferred method of adding antimicrobials to the fibers is in the spinning, or extrusion, portion of the fiber-forming process. At this point, the antimicrobial materials are introduced while the fiber-forming polymers or materials are in the molten or liquid state, either from heat or chemical action. As the fibers harden, the antimicrobial agents are seated into the amorphous zones of the fiber. Less preferred, but nevertheless suitable, is topical coating of antimicrobials onto the fiber surface.
  • the fibers when it is indicated that the fibers "include” an effective amount of at least one antimicrobial agent, it is meant that the antimicrobial agent may either be incorporated into or coated onto the fibers.
  • the antimicrobial agents when the antimicrobial agents are added to the fiber while the fiber is in its molten or liquid stage, the agent lodges in an amorphous, or clear zone within the fiber as it hardens. At this point, due to a process known as “solid state migration", the antimicrobial agent migrates to the surface of the fiber until equilibrium is reached in the internal vapor pressure of the polymer. When equilibrium is reached, the migration ceases and the antimicrobial agent is available to control organisms that contact it, or are in its zone of inhibition.
  • the floor is protected against becoming an environment and home to the micro-organisms.
  • Bacteria and the like passing downwardly through the carpet or other permeable floor covering, as well as various micro-organisms propagated from bodily fluids, will be controlled upon contact with the barrier fabric.
  • passage of micro-organisms down into the floor and other support surfaces or substrates is inhibited, as is further transmission of the micro-organisms to the surface of the carpet or floor covering where they can directly pass to humans, animals, equipment and the like.
  • the present invention provides antimicrobial activity in and around carpet or other coverings which reduces the labor of disinfecting such areas.
  • a greater life can also be imparted to the carpet and, in turn, the contiguous flooring and wall surfaces, thereby reducing the interval between take-up and replacement, as well as the labor and material attendant thereto.
  • a typical carpet is denoted generally by the numeral 10 in Fig. 1.
  • Such a carpet 10 includes a plurality of face yarns 12 which are tufted or sewn into and through a primary backing fabric 14 and which are more securely held in place by the secondary backing fabric 16 attached to the backstitched side of primary backing fabric 14.
  • the secondary backing fabric 16 aids in providing improved dimensional stability and strength of the carpet and covers the back of the primary backing fabric 14.
  • a non-woven fabric 18 is placed between the floor 20 and carpet 10. Although depicted in use with carpet, it is to be appreciated that the non-woven fabric 18 could be utilized with other floor covering materials and possibly with some wall covering materials.
  • Figs. 2-4 the use of the non-woven fabric barrier 18 of the present invention in other building environments has been presented.
  • the fabric 18 has been applied to wall surfaces 22 prior to the application of wallpaper 24.
  • the fabric 18 has been applied to wall surfaces 26 of shower areas prior to the application of tile 28.
  • the fabric 18 has been applied to base structure wall surfaces 30 prior to the application of exterior stucco 32. From the foregoing depictions, it is to be appreciated that the non-woven barrier fabric 18 could be utilized in many other applications where mold, mildew, bacteria and/or fungus and the like are desirably controlled.
  • the phenol-based antimicrobial agent, Microban B was added at a level of about approximately 5000 ppm during the extrusion process. More particularly, the antimicrobial agent was added at a rate of about 2.27 grams per pound of fiber. The resultant fiber was then extruded to about 0.04 to 60 DPF, with about 2 to 20 DPF being preferred and about 2 to 8 DPF being most preferred.
  • the carpet square was sold for commercial use as antimicrobial and was about 4 years old.
