The Defence Institute of Superior Expertise (DIAT) right here on Sunday mentioned it has developed a cotton masks utilizing a natural extract, and claimed that it acts as “virus-neutraliser and resists pathogens successfully. A natural extract obtained from neem oil, turmeric, tulsi (holy basil), ajwain (carom seeds), black pepper, gum arabic, clove, sandalwood and saffron has been used within the non-woven nano-fibre of this three-layered biodegradable masks, named ‘pavitrapati, a patented invention, DIAT’s metallurgical and supplies engineering division Prof Balasubramanian Okay mentioned.
This supplies “antibacterial and antiviral properties”, he claimed, including that these components are immunity-boosting brokers for self-care, as per tips of the AYUSH Ministry. “The product is antibacterial, anti-fungal, antiviral, porous, super-hydrophobic (outer layer of masks), hydrophilic (inside layer) and biodegradable and it will likely be very helpful in our combat in opposition to COVID-19, mentioned Balasubramanian.
Its samples have been examined for air permeability/ breathability, nano-fibre mat porosity, biodegradability and mechanical properties as per the American Society for Testing and Supplies requirements and the outcomes are extremely spectacular, he claimed. “It was discovered to be succesful to be used as surgical masks, and could be discarded after a single use or after soil
publicity,” he added.
The Pune-based DIAT is a deemed college supported by the Defence Analysis and Growth Organisation (DRDO). “The samples were tested to understand the de-naturing capability of protein molecules, and the results demonstrated that the ayurvedic natural herbal extracts interacted and neutralised or killed the aminoacids (that are normally constituents of the shell of virus pathogens) instantly,” the official mentioned.
Impressed by the outcomes, three main masks manufacturing firms have approached DIAT and signed the switch of expertise (ToT) and non-disclosure agreements with the deemed college for mass manufacturing, he mentioned. The product could be prolonged for an infection prevention and management as the non-public protecting tools (PPE) and for waste administration objective, he mentioned. It may be used as a garment, gloves, robe, and for face safety and head cowl, the official mentioned.
In contrast to different masks that are made from artificial materials and are non-degradable in nature, the ‘pavitrapati’ masks is cotton-based, bio-degradable and could be reused as much as three washing cycles. “The biodegradable nanofibre mat/membrane finds application as a protective membrane for PPE. This technology has proved that the non-woven membrane between the woven fabrics supports to block droplets, splashes, sprays, bacteria, and viruses,” he mentioned.
