Nanotechnology In Textiles

Key Concepts and Definitions

Nanotechnology refers to the manipulation of matter at the nanoscale, typically between 1 and 100 nanometers. At this scale, materials exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts. In the context of textiles, nanotechnology involves integrating nanoscale materials or structures into fabrics to enhance their functionality.

Key terms to understand include:

• Nanoparticles: Tiny particles with dimensions measured in nanometers, often used to impart specific properties like UV resistance or antimicrobial effects.
• Nanofibers: Fibers with diameters in the nanometer range, offering high surface area and unique mechanical properties.
• Self-assembly: A process where molecules organize themselves into structured arrangements, often used in creating nanostructures in textiles.

Historical Milestones in Nanotechnology in Textiles

The journey of nanotechnology in textiles began in the late 20th century, with significant milestones marking its evolution:

• 1990s: Introduction of nanocoatings for water and stain resistance.
• Early 2000s: Development of antimicrobial fabrics using silver nanoparticles.
• 2010s: Emergence of smart textiles incorporating nanosensors for health monitoring.
