Sustainable Nanotextile technology represents a ground breaking advancement in the textile industry, merging nanotechnology with eco-friendly practices to create high-performance materials with minimal environmental impact. Nanotextile products are innovative materials enhanced with nanotechnology to deliver advanced functionalities beyond traditional textiles. The objectives of nanotechnology encompass a wide range of scientific, industrial, and societal goals, aimed at leveraging the unique properties of nanoscale materials and structures. The products are designed for various industries and offer improved performance, durability, and sustainability. This interdisciplinary approach leverages nanoscale engineering to enhance textile properties such as durability, water repellency, antibacterial activity, UV protection, and self-cleaning capabilities, all while promoting resource efficiency. This paper also analyzes the consolidation of nanotechnology in the textiles market to assess worldwide trends and patent coverage. Here are some notable nanotechnology textile products and their applications that are collectively taken for discussion, such as antimicrobial products for medical and surgical products; self-cleaning for laboratory uniforms; water-repellent for sports/home textile products; UV-resistant fabrics for sportswear; lightweight, and high-strength fabrics for military wear.
