Area of Science:

  • Environmental Science
  • Materials Science
  • Chemical Engineering

Background:

  • Indoor air pollution from textile malodors poses health risks.
  • Current odor elimination technologies are insufficient.
  • A need exists for effective and eco-friendly odor removal solutions.

Purpose of the Study:

  • To develop and evaluate an innovative technology for eliminating textile-associated malodors.
  • To investigate the efficacy of Engineered Water Nanostructures (EWNS) in deodorizing common indoor smells.
  • To explore the underlying mechanisms of odor removal by EWNS.

Main Methods:

  • Utilized electrospraying to generate Engineered Water Nanostructures (EWNS).
  • Applied EWNS to textiles contaminated with typical indoor odors (smoking, cooking, perspiration).
  • Employed headspace SPME coupled with GC-MS for odor quantification.

Main Results:

  • Achieved high removal efficiencies for smoking (95.3%) and cooking (100%) odors.
  • Demonstrated significant, though lower, removal of perspiration odor (43.7%).
  • Identified Reactive Oxygen Species (ROS), primarily hydroxyl and superoxide radicals, as the active deodorizing agents.

Conclusions:

  • EWNS technology offers a promising, environmentally friendly approach to textile deodorization.
  • ROS within EWNS effectively neutralize odor-causing compounds via oxidation.
  • This method holds potential for mitigating indoor air pollution from malodorous textiles.
