Recently, nanomaterials are widely preferred from textile manufacturers due to their excellent properties such as high mechanical strength, chemical resistance, water repellence, antibacterial properties etc. Still, a lot of research are carried in this area to improve textile products which already be used. To obtain nano-enhanced textiles, different kinds of processing techniques are needed because existing manufacturing processes are not very suitable. In this case, manufacturing costs, quality control and homogeneity of nanoparticle dispersion through the fabric become problematic issues. Another important issue to be considered for nanoparticle usage is any effects on human health and environment. Although some studies have focused on this issue, still toxicity of nanomaterials in textile product is not fully understood.
In fabric composites, conventional, natural or synthetic fibers are generally mixed with nanomaterials to enhance the performance or create novel properties to the fabric. Some examples of nanomaterials and benefits which can offer to textiles are listed below.
  • Carbon black nanoparticles/nanofibers: electrical conductivity, high mechanical properties and abrasion resistance
  • Carbon Nanotube: Excellent mechanical properties with lightweight, electrical conductivity and thermal conductivity
  • Metal oxide nanoparticles: Antimicrobial properties, photocatalytic, electrically conductive and UV protection
  • Metal nanoparticles: Antimicrobial, Aesthetic properties and solar cells
  • Nanoclay: Fire retardancy, electrical and chemical resistivity, UV shielding
By the help of these nanomaterials, textile products can be used different purposes such as;
  • Antibacterial and odor-reduced sports fabrics with improved mechanical properties
  • Personal protective textiles with enhanced chemical, heat resistance and durable.
  • For military purposes, flexible body armor, radio shielding and ballistic protection.
  • Medical textiles with antimicrobial wound dressing and bedding
  • Wearable electronics with conducting fabrics

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
