Antibacterial Polyester Yarn

Introduction

Polymers can be easily infected by bacteria or fungi, which consequently results in the transmission of diseases and severe infections. Prevention of microbial colonization onto the polymeric surfaces can be fulfilled by adding active antimicrobial agent like silver nanoparticles into the polymers. Polyester is a category of polymers that contain the ester functional group in their main chain. In comparison with other industrial fibers, polyester fibers have high tenacity, low water absorption and minimum shrinkage. This material is widely used in the clothing industry. Silver ions and its compounds are extremely lethal for a wide range of bacteria, whilst they show very low toxicity for human cells. Therefore, silver is widely used as an antibacterial agent. 

Application

• Production of antibacterial textiles

Advantage of Using Nanotechnology

Silver is an effective antibacterial agent which in the form of nanoparticle is highly diffusible, insofar as it allows the chemical reactions to occur at a high rate. The specific surface area and dispersion capability of silver nanoparticles cause better contact with microorganisms which consequently improves the antimicrobial activities. The antibacterial property of this product was evaluated by ISIRI 11070.
