Disinfectant composition for textile and related substrates, and method of treating a substrate to provide disinfecting antibacterial, antiviral and antifungal, wash durable, optionally enhanced with multifunctional properties

Abstract

The present technology provides a disinfectant textile composition having antimicrobial, wash durable, optionally enhanced with multifunctional properties. The technology also provides a method of treating a textile substrate. The method comprises applying a disinfecting treating composition using one or more of an exhaust, padding, coating or spraying process. The treating composition comprises an antifungal agent and further comprises a cross-linking agent. The method also comprises drying the textile substrate using a heat setting process.

AI Technical Summary

Benefits of technology

The present invention provides a textile that has been treated with a combination of various chemicals to make it antimicrobial, anti fungal, and anti viral. The chemicals used include quaternary ammonium organosilane compound, silver chloride, poly-glucosamine, propiconazole, and poly-hexa-methylene-biguanide. The treatment is durable and the textile is mildly hydrophobic. The textile can also be made multifunctional by adding additional treatments such as water and oil repellents, abrasion resistant agents, antistatic agents, and others.

Problems solved by technology

The prevalent environment in these locations can result in the textile being not only a fertile breeding ground for these pathogens, but also a perfect substrate from which these pathogens can be spread to others resulting in infections, may be even death, higher operational costs and waste through redundancy and rot.

As such, there is a very realistic danger of microbiological contamination on the textile surfaces.

Additionally, danger of staining of apparel due to ketchup, blood, sputum, honey, human excreta and moisture are also problems faced by users in various circumstances.

Not only do such stains look ugly, but they also are fertile breeding grounds for various harmful bacteria, fungi and viruses on the textile surface and in its cross section.

Also, garments such as jackets and overcoats, which directly don't come in contact with the skin, are also susceptible to infection transfer through contact with the inner garments, which are possibly infected.

As such, it is evident that textile contamination by microbiological pathogens is a major cause for concern.

Security and military personnel, stewardesses and other airline personnel are especially prone to disease and skin problems as they may have to wear the same clothing for more than one day.

Not only do these soiled apparel cause health problems to the wearer but are also the breeding grounds for the spread of bacteria, fungi and virus based diseases.

In the context of the hospitals, the presence of microbes is far more threatening.

Patients sleep on sheets and pillow cases that have extremely high risk of contamination due to bacterial and microbial growth resulting from excretions of the body.

The mattresses and pillows are also likely to become infected due to the fact that these aren't washed.

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.

Healthcare workers are very often subjected to the contamination either from soiled textiles used by patients or due to excretions of the body.

a. Hospital or Healthcare transmitted diseases to a great extent are textile based transmissions.

b. Doctors and Patients tend to infect each other through textile contact.

c. Current methods of washing lead to damage of the textile.

Laundry washing of regular textiles leads to excess consumption of water.

Moreover, huge quantities of detergents are used to launder the clothes, and this process is excessively time consuming due to long laundry wash times. There is also a pressing need to address this problem by creating textiles which require lesser amounts of water, time and detergents to clean.

While there is availability of fresh water resources, the water therein is often found contaminated with E.

As such, the levels of contamination in most of these water resources are considerable.

If used for drinking, such contaminated water could lead to outbreaks of diarrhea, cholera and a host of other diseases, as indeed evidenced by studies across the world.

While systems do exist which can kill the waterborne microbiology using chemical dosing, the use of such chemicals over extended periods is harmful for the human body.

Moreover, yet other systems that can separate or kill bacteria in water use electricity, which is not readily available in a large chunk of underdeveloped regions across the globe.

While many people have indigenously used textiles to sieve water and make it more potable, those textiles cannot kill microbiological pathogens.
