To develop Antibacterial/Odour free/Hygienic Under Garments, Vest, Towels, Bedsheets, Upholstery using Antibacterial AntiViral Agent in the form of Nano Silver Colloidal Solution. Application of Antimicrobial to Textiles: We have done extensive research on making textiles antibacterial in last three years and developed the antimicrobial product based on nano silver colloidal solution.The antimicrobial can be applied on garments by using simple method based on Dip-Hydro extraction-Dry for garments, Pad-Dry for textile fabrics, Spray-Dry for carpets etc., at final finishing stage. Introduction: The antibacterial activity of silver has been known since ancient times. The King of Persia during war used silver container for boiled water storage. Silver is still used as a disinfectant for swimming pool. In case of nano silver, the antimicrobial agent contains nano silver particles that get rid of bacteria by killing them in warm and humid conditions. The silver largely depends on killing the bacteria by oxidation. This is the reason the bacteria cannot get immune to the silver. The textile treated with nano silver agent will have antibacterial, antifungal, antivirus, odour free properties. The bacteria and fungi, which can be found almost everywhere, are able to quickly multiply, depending on the moisture, nutrients and temperature levels. Dirt, dust & sweat act as food for bacteria. Some bacteria populations may double every 20-30 min under ideal conditions (36-40�°C, pH 5-9), meaning that one single bacteria cell can increase to 1,048,576 cells in just 7 hrs. The Nano Silver Finish is effectively used in clothing which can be ridden with bacteria and fungi after getting drenched in sweat. With nano silver antimicrobial finish, the garments smell fresh and deter the growth of bacteria responsible for the unpleasant odour. Also the textiles which are less frequently washed like denim and home textile, become the home of bacteria because of dirt/dust present, acting as nutrient for bacteria to grow in millions. Therefore, all the textile materials which are subjected to sweat, dirt and dust and are not washed frequently, needs antibacterial characteristics to prevent user from pathogenic disease like various skin infections, pneumonia, common cold etc.
