Definitions
- the present invention relates to a chemical treatment that may be applied to a protective article.
- the invention relates to material compositions for controlling the spread of pathogens and infection diseases.
- the present invention relates to antimicrobial and antiviral compositions, a method of manufacturing or treating a textile material, such as woven and non-woven textiles, yarn and/or fiber, with antimicrobial and antiviral compounds in such a manner to chemically bind or attach said compounds to the textile material, and to the treated textile material which performs as a disinfectant or sterilizer on its own.
- the treated textile material exhibits wash-durability and non- leaching properties, and can be provided with multifunctional enhancements, such as hydrophobic properties on the surface.
- the present invention is also directed to a textile material to which one or more antimicrobial or antiviral agents are adhered.
- the agent(s) is/are adhered to the textile material in such a manner that they are not released from the textile even if the textile is wetted or washed, so that the textile is reusable. Washability and/or usability of the textile are improved where one or more agents are adhered to the textile.
- the textile material can be used, e.g., in a reusable textile product.
- the invention further relates to a method of finishing a textile material by applying and binding antimicrobial and/or antiviral agents to the textile material so that the agents are essentially irreversibly adhered to the finished textile material.
- Sanitizer Disinfectant Sterilizer es nts s Textile materials like woven and non-woven fabrics, yarns and/or fibers are used for a variety of purposes and in a variety of environments. As such, there is a realistic danger of microbiological contamination on the textile surfaces. These substrates are used to filter air or water, but work only by blocking, and do not eliminate the contamination. In recent times, studies have shown that textiles carry nosocomial infections from patient to patient in hospitals. Soldiers often wear clothes for extended periods of time, without washing, which often results in fungal and bacterial infection to the wearer. Danger of staining of apparel due to ketchup, honey, sputum, blood, human excreta and moisture are also problems faced by users in various circumstances.
- the mattresses and pillows are also likely to become infected due to the fact that these are not washed. They, in turn, can transmit infection to the patient.
- Sheets, pillow covers, gowns, and curtains are subjected to contamination from open wounds and other medical conditions, such as coughing, wheezing, etc.
- Patients' gowns are contaminated by sweat and/or human excretion such as urine, stool and vomit. This leads to the growth of microorganisms like bacteria, viruses and fungi.
- Healthcare workers are very often subjected to the contamination either from soiled textiles used by patients or due to excretions of the body. Medical personnel are major causes of transmitting bacterial infection from one patient to another. Current medical textiles offer no barrier protection.
- Industrial, medical and home fabric softener of interest are liquid compounds that alters the textile product’s fibers by coating the fibers and making the textile product feel better to the touch (known as hand).
- the softening agents applied are hygroscopic or lubricating agents, which allow for the fibers to slide within the fabric structure, assisting with easier deformation and creasing of the fabric. The duration of the effect is temporary since the softeners applied during the treatment are eliminated by future machine washings.
- a number of textile softener chemistries exists such as anionic and cationic surfactants, siloxane polymeric- based softeners and non-ionic surfactant softeners.
- Fabric softeners work by depositing lubricating oil type chemicals on the fabric that make it feel softer, reduce static cling, and remove odors or impart a fresh fragrance.
- the textile garment and hosiery industries have treated textile fabrics in the mills with antimicrobial agents to reduce the attraction and population growth of bacteria. The result is a reduction in odors generated by the bacteria on the garments and hosiery.
- Application of the antimicrobial agent is done by padding, spraying or foaming an ingredient or ingredients onto fabric and fusing the chemistry into the fabric (heat setting) in a heating tunnel for a more permanent treated garment.
- Grey US 4,166,794 teaches a combination product of a liquid, bleach softener composition for use in one or more of the wash, rinse and tumble dry cycles of a laundering process comprising a water soluble peroxy bleaching agent and a water soluble cationic nitrogen softener compound, at least 50% thereof being an aliphatic, quaternary ammonium compound and/or a cationic heterocyclic imide such as an imidazolinium or pyridinium compound. Grey does not mention the incorporation of antimicrobial agents to reduce micro-organism populations.
- the peroxy bleaching agent was for the removal of food or beverage stains.
- US 4,184,004 to Pines et al discloses fabrics namely cellulose and blends of cellulose and polyester that can be treated with the trimethoxysilyl functional groups of a terpolymer chemistry using the siloxane and an epoxy polyoxyalkylene. The results produced a soft hydrophilic fabric.
- US patent 4,425,372 to Baldwin reveals industrial chemical biocidal methodologies to make antimicrobial, non-leachable fabrics using Dimethyloctadecyl 3-trimethoxysilyl propyl chloride as the bactericidal and bacteriostatic chemistry.
- Concentrations ranging from 0.2 to 1.1 wt% are used as coatings and approved by EPA and FDA for medical devices such as drapes and pre-op fabrics.
- Baldwin states a 95% efficacy against bacteria in one hour but did not disclose the species.
- Baldwin did not consider the evolution of bacteria within hospital settings due to horizontal gene transfer of Staphylococcus aureus to become resistant to antibiotics (methicillin) and making the MRSA more difficult to kill with the one biocide namely the dimethyloctadecyl 3-trimethoxysilyl propyl chloride.
- Baldwin does not disclose the addition of a textile softener and the combined synergies.
- US Patent 4,721,511 to Kupits describes a leach resistant antimicrobial fabric namely a non woven cellulose, polyethylene, or polypropylene treated with (3-trimethoxysilyl) propyl octadecyl dimethyl ammonium chloride and an organic titanate.
- Humans are exposed to bacteria in much of their environment on a 24-hour daily basis. There are beneficial species of bacteria however humans who are immune compromised can be more susceptible to infections.
- Clostridium difficile spores float in the air until nine spores combine to form a terminal loading which then allows the grouping to fall due to gravity. The result if contacted and ingested results in illness.
- the anti-microbial, anti-viral, fabric softener compounds also imparts antimicrobial efficacy to the wash water during the rinse cycle and will impart a bacteriostatic environment on the washing machine interior walls.
- the invention provides a liquid antimicrobial and antiviral fabric treating composition comprising:
- Ri is an C 1-30 alkyl group, preferably C 8-30 alkyl group
- R 2 and R 3 , R 4 and R 5 each independently are an C 1-30 alkyl group or hydrogen
- X is a counter ion, such as CT, Br ' , I' or
- a purpose of this invention is to expand upon the fabric softeners benefits by the addition of incorporating antimicrobial properties to the fabric during the same wash machine rinse cycle treatment. The results would reduce or kill bacteria on the fabric fibers, and reduce odors, while making the garments soft and more appealing to the touch.
- Antimicrobial treated fabric would affect population growth of micro-organisms on the fabric and the spreading of micro-organisms from one contact point to another contact point.
- the continued evolution of micro-organisms species to generate resistant strains due to horizontal gene or RNA transfer poses a more aggressive response to antimicrobial discipline in community environmental settings such as adult care facilities as well as health care environments.
- the chemistry of a trimethoxy silane quat to impinge onto the fibers as an antimicrobial mesoporous self-assembling silane polymeric allows for a persistence efficacy of antimicrobial properties.
