These microbial will grow rapidly if the suitable environment were given to them, which would cause a lot of diseases happened when contact them. And will spread or transmit to other people easily. That is how a lot of people have the illness happened and get killed. That is the reason why Antimicrobial textiles were invented and had been paid a highly attention to its development by most of the people in the world. It can be foreseen obviously that antimicrobial textile will have a lot of demand in the market and create a lot of profits and commercial opportunity under the increasing of the attention of personal health, daily hygiene and expect of the quality of living life style by the consumer. By ITIS reports, Japan has the largest antimicrobial textile market in the world, which is larger than US and European markets . In Canada it has about 350 millions Canadian Dollars of antimicrobial textile market. It is recognized that will have 10% growth rate of the world antimicrobial textile market within 8 years period. It is the trend of the future textile market. Introduction

It destroys only the pallium of bacteria or fungus, which will be interrupted the proteinase, DNA, thiol group synthetized and stop their reproduction mechanism.The interrupted synthetized bacteria will release its proteinase from the destroyed pallium, which means sending the chemical signal (in dangerous) to other bacteria. That will prevent other bacterial to approach those material which has iodine contain. Then, the bacterial will not be able to survive without required reproduction nutrition.Iodine Antimicrobial MechanismThe information contained herein is the exclusive property of TTRI and shall not be distributed, reproduced, or disclosed in whole or in part without prior written permission of TTRI.
