Why embed the particles instead of coating them?
Many conventional companies rely on coating the surface of fabrics with silver nanoparticles to provide antibacterial properties. While this method is initially effective, it suffers from several significant drawbacks, including:
-
Loss of effectiveness over time: With repeated washing, the surface particles begin to wear off, leading to the fabric losing its antibacterial properties.
-
Uneven accumulation of particles: Coating does not ensure uniform distribution, leaving some areas without effective protection.
In contrast, when nanoparticles are embedded directly into the fibers during the manufacturing stage (during the spinning of the polymer in the case of synthetic fibers like polyester or nylon), they become an integral part of the fabric’s structure. This approach ensures:
-
✔️ Long-lasting resistance to bacteria and odors, even after dozens of washes
-
✔️ Consistent and precise distribution of nanoparticles throughout the fibers
-
✔️ Reduced need for harmful surface chemicals, which benefits the environment
🦠 How do silver nanoparticles work?
Silver nanoparticles release silver ions (Ag⁺), which have a powerful ability to disrupt bacterial cells by:
-
Interacting with proteins in the bacterial cell wall
-
Damaging the DNA of the bacteria
-
Interrupting cellular respiration, ultimately leading to cell death
