Description

IONIZED PERFORMANCE FABRIC WITH
ANI'ΪMICROBIAL/ANTIBACTERIAL/ANTIFUNGAL PROPERTIES
TECHNICAL FIELD AND INDUSTRIAL APPLICABIU ΓY OF THE INVENTION
[0001] The present invention relates generally to the clothing field, and more particularly, to specialty garments, surgical masks, bandages and tapes and compositions for treating those fabrics and products. The compositions are also useful in treating medical wraps and domestic fabrics such as sheeting, pillowcases, bed coverings and throws. The compositions are furthermore useful in imparting antimicrobial/antibacterial/ antifungal properties to textile fabrics and garments but also to polymers such as polyvinylchloride, nitrile rubber and polyacrylates, polyethylene s and polyvinylidene chloride for use as food packaging, surgical gloves, examining gloves, food service gloves and the like.
BACKGROUND OF TIIL; INVENTION
[0002] The present invention relates to specialty fabrics and clothes such as shirts, pants, socks, underwear, sweaters, coats, gloves, mittens, shoes, hats and other head wear. The invention also relates to surgical masks, bandages and tapes as used in the medical field. Individuals wearing clothing, bandages, wraps and/or tapes constructed from the specialty fabric of the present invention against their skin have observed substantial increases in oxygen levels in the bloodstream, circulation and muscle recovery, static and dynamic endurance, performance, speed, quickness and reaction time. Further, wearers of the specialty fabric have also experienced energized endorphins, increases in immunologic A, an important immune factor, and enhanced antiinflammatory effectiveness. Wearing the clothes, bandages, wraps and/or tapes of the present invention enables an athlete to perform better, perform longer and have greater muscle elasticity, less warm up time and faster recovery. A person sleeping on mattress covers, sheets and pillowcases containing this treatment will enjoy a deeper, more relaxing sleep and awake feeling more rested. Incorporating an antimicrobial/antibacterial/antifungal agent into this composition will allow the wearer not only to feel fresher but the item of clothing such as shirts, pants, socks, underwear and undergarments, sweaters coats, gloves, mittens, shoes, hats and other head wear, along with surgical masks, bandages and tapes along with surgical gloves, examination gloves, food service gloves and food packaging will inhibit the growth of gram positive and gram negative bacteria, aspergillus niger (black mold) and any other harmful mold or fungus or harmful bacteria.
(0003] The antimicrobial/antifungal agents can be dispersed into plastic polymers such as polyvinyl chloride, polyvinyl] dene chloride, ethyl vinyl acetate, nitrile rubber, polyacryiates, neoprenes or any other film forming thermoplastic polymers and non- woven scrims thus providing a product which will inhibit the growth of harmful bacteria and fungi. Jn addition, the incorporation of antimicrobials into the polymeric film affords protection to the wearer and also does not allow any harmful bacteria or fungi to be transferred to any surface with which it comes in contact. By incorporating a source of negatively charged ions into the thermoplastic polymer along with the antimicrobial agent(s), the ability of the antimicrobial is further enhanced. The negatively charged ions present will attract any positively charged ions such as gram positive and gram negative bacteria, pollen, pet dander and other pollutants, bonding with them, holding them in place thus making the antimicrobial agent considerably more effective.
[0004] Products which can be treated with this composition are food packaging and preservation films, athletic wear, footwear, household products, cleaning products, plastic containers, medical devices such as stents, catheters, shunts, needles; also, toys, sanitary products, diapers, wipes plastic cutlery, filtration media, automotive products such as steering wheels, headliners and interior upholstery. Also, carpeting and floor coverings, polymeric mattresses such as blown neoprene foams, visco-foams. Also, computer keyboards, cell phones, doorknob covers, or any other substance into which antimicrobials and negatively charged ions can be placed. Also, it is possible to incorporate this technology into synthetic fibers such as, but not limited to. nylon, polyester, polypropylene, acrylic in the dope or liquid state. Thus a fiber can be spun which inherently contains this technology.
[0005] Further, when worn in a surgical operating suite, treated gloves will provide the surgical team with antimicrobial/antibacterial/antifungal properties. Not only will the surgical team realize these properties and their protection from gram positive and gram negative bacteria and black mold, the patient will also receive these benefits because the gloves will be inherently treated at point of manufacture,
[0006] Food packaging films, treated with this composition will extend shelf life of food and protect against the effects of salmonella and E. coli bacteria and other gram negative and gram positive bacteria. The incorporation of food grade silica and aluniinosilicates will allow the thin film food packaging polymer such as polyvinyls, polyvinylidene chloride, polyethylenes or any other polymer which can be used in food packaging to absorb ethylene gas which is given off by fruits and vegetables, thus increasing and protecting freshness.
[0007] Food service personnel, wearing gloves treated with this composition will be protected; and furthermore, because the gloves are inherently treated, no harmful bacteria will be transferred to other surfaces with which these gloves come in contact. Because this composition consists of a combination of ionized technology and antimicrobial /antibacterial /antifungal agents, the wearer will experience the benefits of ionized substrates. Individuals wearing these treated gloves will feel more energized and will be subjected to less muscle cramping in the hands because of lactic acid management in the muscle tissue.

[0017] In accordance with the present invention an ionized finish is durably fixed to a textile fabric by treating the fabric in an appropriate composition. The particular chemistry utilized to impart ionized groups to the fabric depends upon the particular textile fiber and the balance of physical and chemical properties expected from the finished fabric. The goal is provide an ionized finish that will function to enhance the physiologic and athletic performance of the wearer or to provide a more relaxing night's sleep.
[0018] One composition useful in the present invention comprises in weight percent about 0, 1 to about 15.0% fixative, about 0.1 to about 10.0% ionising agent, about 0.1 to about 8.0% fixative catalyst, about 0.1 to about 8.0% of a material selected from a group consisting of polyolefin, oxidized polyoleiln and mixtures thereof, about 0.0 to about 8.0% amino functional silicone, about 0,01 to about 4.0% wetting agent, about LO to about 3.0% antimicrobial/antibacterial/anti fungal agent and the remainder as a carrier. In one particularly useful embodiment the composition includes about 0.1 to about 8.0% amino functional silicone, In yet another particularly useful embodiment the composition comprises about 2.0 to about 8.0% fixative, about 1.0 to about 5.0% ionizing agent, about 1.0 to about 4.0% fixative catalyst, about 0.2 to about 4.5% polyolefin, oxidized polyolefin or mixtures thereof, about 0.2 to about 4.0% aminofunctionai silicone, about 0.1 to about 2.0% wetting agent, about 1.0 to about 3.0% antimicrobial/antibacterial/ antifungal agent and any remainder as carrier.
f0019] In this compositional embodiment the fixative aids in fixing the sulfamate salts that provide the ionization effect to the fabric being treated. This is particularly true when the fabric includes cellulosic fibers. Further, the fixative may also serve to provide an ionization effect. For example, a polymer containing rnaleic acid such as a copolymer of maleic acid and acrylic acid may fix itself on a cellulose or a synthetic fiber and have ionization properties. The fixative may be selected from a group consisting of urea, dimethyloldihydroxyethyleneurea, dimethylureaglyoxal and mixtures thereof.
[0020] The ionizing agent is selected from a group including any acid or acid salt that serves as an agent to provide ionization properties and to adjust the pH. The acid or acid salt may, for example, be selected from a group consisting of sulfamic acid, sulfamic acid salt, ammonium sulfarnate, socium sulfatnate, magnesium sulfamate, phosphoric acid, the sodium salt of phosphoric acid, polycarboxylic acid, citric acid, bυtanctetracarboxylic acid, polymers and copolymers containing maleic acid and acrylic acid and their sodium salts and mixtures thereof. Other useful ionizing agents include but are not limited to tourmaline, zeolite, diatomite, silica gel, amethyst, chitosan, germanium, titanium and mixtures thereof.
[0021] The poly olefin and/or oxidized polyolefin serves as a softener and/or sewing lubricant. The polyolefm/oxidized polyolefin is typically polyethylene and/or polypropylene. The softener must be used at a low level (about 0.5%) where good wicking properties are desired.
[0022] The fixative catalyst may, for example, be magnesium salts and selected from a group consisting of magnesium chloride and magnesium chloride activated with citric acid. For a catalyst useful in fixation of maleic acid containing polymers, salts of phoxphoric acid may be used at a pH of 2.6 - 4.0. The aminofunctional silicone is ionizable so as to impart ionization properties to the fabric being treated. The aminofunctional silicone may, for example, be selected from a group consisting of various silicone polymers containing amine groups. The amine groups may be primary, secondary or tertiary, or quaternary and mixtures thereof. Other silicones useful in the present invention include polydimethylsiloxane, amodimethicone, phenyltrimethycone, reactive silicones containing ethyl, methyl, amine, carboxy, hydroxyl and epoxy groups and silicones having AB and ABA functionalities.
[0023] The wetting agent may be selected from a group consisting of nonionic and anionic surfactants and mixtures thereof. The wetting agents are usually nonionic surfactants with from 12 to 18 carbon atoms in the oleophilic portion of the molecule. In the hydrophilic portion of the molecule, the ethylene oxide reacted segments usually vary from 5 to 10, Anionic surfactants may be needed to make the finishing solution compatible.
[0024] The antimicrobial/antibacterial/antifungal agent is typically selected from a group of agents consisting of an aqueous dispersion based upon 5-chloro-2-(2,4 dichlorophenoxy)phenol, a water based suspension of dϋodomethyl-p-tolyl sulfone, a finely divided powder of diiodomethyl-p-tolyl sulfone, a finely divided suspension of imidazole and pyrithione, a water based solution based upon silver ion technology, an essential oil, sideritis oil, oregano oil, tea tree oil, mint oil, sandlewood oil, clove oil, nigella sativa, onion oil, garlic, lavender oil, lemon oil. lemon myrtle oil, neem oil, eucalyptus oil, peppermint oil, cinnamon oil, thyme oil, alcohol, ethyl alcohol, isopropyl alcohol, a phenol, chlorine, iodine, a mercury salt, a quaternary ammonium compound, an oligodynamic metal, copper, heavy metals, a glycoprotein, lactoferrin and mixtures thereof. Usually the carrier is water. However, other carriers may be utilized, Useful carriers include, but are not limited to, water, air, alcohol, polyol, polyester polyol, sugar alcohols such as maltitol, sorbitol, mannitol, isomalt, xylitol, lactitoL erythretol, polyethylene glycol, polypropylene glycol, poly(tetramethylene ether)glycol, diethylene glycol reacting with phthalic acid to form a polyester fiber, capro lactone, a polyester polyol formed by reacting pentaerythritol with gamma-butyrolactone, hydroxyl terminated polybutadienes used in forming urethanes, natural oil polyols, peanut oil, canola oil and castor oil. In addition, plasticizers such as, but not limited to, dioctyl phthalate and diisononyl phthalate can also be used as carriers. .
[0025] When treating fabric made from synthetic fibers and, particularly polyesters, the composition may be modified to include an effective amount of blocked copolymer of polyester/polyethylene glycol such as is available from Piedmont Chemical in High Point, North Carolina. This blocked copolymer functions to make the polyester fibers of the fabric hydrophilic and thereby improves the binding of those fibers with the acid/acid salts with ionization properties.
[0026] The composition is applied to the fabric by blotting, spraying, soaking, foaming or any other appropriate means. The composition is then dried and cured. The percent wet pickup may vary from 10 to 120 percent depending on the fabric and the level of treatment desired. After drying, the cure temperature will depend on the time permitted for curing. Conditions may very from, for example, 10 seconds at 38O0F to 20 minutes at 28O0F.
[0027] Three possible embodiments of the performance fabric of the present invention are illustrated in Figures 1-3, Of course, it should be realized that these different embodiments are simply presented for purposes of illustration and that the invention should not be considered as limited thereto. [002Sj In the first embodiment illustrated in Figure 1, the fabric IO comprises a single layer of a substrate 12 treated with one of the compositions previously described. The fabric substrate may be a cellulosic material, a noncellulosic synthetic material or a blend of the two. Fabric substrates treated with the composition of the present invention include but are not limited to cotton, linen, rayon, polyester, nylon, elastomers, acrylics, wool, silk, and blends and mixtures thereof.
[0029] An alternative embodiment of the performance fabric 10 of the present invention is illustrated in Figure 2. In this embodiment the fabric 10 comprises a substrate layer 14 treated with the previously described composition in order to provide ionized properties and a second layer 16 of a filter material. That filter material ma\ , for example, comprise a fabric treated with a known filtering material such as charcoal, activated carbon, chlorophyll, baking soda, activated alumina, soda lime, zeolite, calcium oxide, potassium permanganate diatomaceous earth or the like. In one possible embodiment that layer 16 comprises a fabric substrate encapsulated with activated carbon using a poly film- Such a filtering layer 16 reduces the release of body odor to the environment, allows for enhanced moisture management, while also protecting the covered skin from noxious chemicals in the environment. Thus, it serves a number of functions.
[0030] Λ third embodiment of the performance fabric 10 of the present invention is illustrated in Figure 3. In this embodiment the performance fabric 10 comprises three separate layers. The outer two layers 18, 20 are constructed from a cellulosic material such as cotton, rayon, linen and any mixtures thereof or a noncellulosic synthetic material such as nylon, polyester, elastomers, acrylics, and mixtures thereof or even a blend of the two types of materials/ fibers or natural fibers such as silk, wool, ramie, jute or blends thereof. Either or both of the layers 18, 20 may be treated with the performance enhancing compositions of the present invention in order to provide an ionization effect. A third layer 22 of filtering material may be provided between the first two layers 18, 20. The third layer 22 may comprise a fabric substrate treated with a filtering agent in the manner described above like the layer 16. (0031] A medical mask 50 is illustrated in Figure 4. The medical mask 50 includes a body 52 and tie straps 54. Λt least the body 52 of the mask 50 is constructed from the ionized fabric of the present invention illustrated in any of Figures 1-3,
[0032] A medical tape 60 is illustrated in Figure 5. The medical tape 60 includes a strip of fabric 62 having an adhesive 64 on one face 66 thereof. The strip of fabric 62 is constructed from the ionized fabric of the present invention as illustrated in any of Figures 1-3,
[0033 j Substantially any type of clothing, medical wraps, surgical masks, bandages, medical tapes and domestic fabrics such as sheeting, pillowcases, bed covering, and throws may be constructed from the performance fabrics of the present invention illustrated in Figures 1-3. For example, the fabrics may be utilized to construct shoes, socks, pants, shorts, underwear and undergarments, shirts, sweaters, scarves, gloves, mittens and any type of hat or other head wear. All of the performance fabrics illustrated in Figures 1-3 include an ionized characteristic that provides various beneficial physiological effects to a wearer of clothing constructed from the fabrics. In addition the Figure 2 and 3 embodiments incorporate an additional filtering layer 16, 22 that functions to both reduce body odor, provide comfort through moisture management, and protect the pores of skin covered by the fabric from noxious gaseous materials in the environment. Thus, unique, multiple benefits are achieved by the wearer heretofore unknown in the art.
[0034] The fibers of the fabric substrates utilized to make the clothing may be imparted with ionized properties by a number of methods. The chemistry will depend on both the fibers and the particular chemical group to be fixed. As would be expected, cellulosic fibers respond differently from non-cellulosic synthetics. Furthermore the finish will also depend on the final balance of physical properties desired for the garment [0035] For cellulosic fibers such as cotton, rayon, and linen, ionic groups may be fixed by a number of methods. Some of these approaches include (1) partial carboxymethylation using a sodium salt of chloroacetic acid and sodium hydroxide; (2) reactive polycarboxylic acids with appropriate catalyst, pH and heat; (3) phosphorylation with ammonium phosphate and urea; (4) sulfation with appropriate salts of sulfamic acid; (5) fixation of reactive dyes and colorless reactive dyes; {6} fixation of epoxy functional cationic compounds: and (7) fixation of ionic polymers such as carboxymethyl cellulose, sulfonated phenolic/ formaldehyde polymers, carboxylated acrylic polymers, partial oxidized polyethylene and amino functional silicones.
[0036] Non-cellulosic synthetic fiber such as polyester and nylon are not as reactive as the cellulosic fibers. For these non-cellulosic synthetic fibers fixation of the reactive groups must be more on the surface. Reactive polycarboxylic acid compounds have been effective in fixing cationic compounds such as choline chloride. This reaction in combination with oxidized polyethylene and aminofunctional silicones has been effective in achieving desirable ionic properties on synthetic fibers.
[0037] The following examples are to further illustrate the invention but it is not to be considered as limited thereto.
