Area of Science:

  • Materials Science
  • Textile Engineering
  • Fire Safety Engineering

Background:

  • Firefighting suits require advanced materials for protection against heat and flames.
  • Waterproof and breathable layers are crucial components of modern firefighting apparel.
  • Alginate fibers offer inherent flame-retardant properties, while aramid fibers provide strength and thermal resistance.

Purpose of the Study:

  • To investigate the impact of varying alginate fiber blending ratios on the flame-retardant properties of waterproof and breathable layers.
  • To evaluate the performance of alginate/aramid blended fabrics for firefighting suit applications.
  • To assess the contribution of alginate/aramid waterproof and breathable layers to the overall thermal protection of firefighting apparel.

Main Methods:

  • Preparation of waterproof and breathable layers using needle-punching and hot-pressing nonwoven reinforcement processes.
  • Fabrication of base cloths with different alginate/aramid fiber blending ratios.
  • Performance testing, including flame retardancy, thermal stability, and thermal protection evaluation.

    • Main Results:

    • Alginate blended base cloths exhibited significantly higher char residue content compared to pure aramid.
    • The addition of alginate fibers improved the flame retardancy and thermal stability of the waterproof and breathable layers.
    • Alginate/aramid blended fabric layers demonstrated superior overall performance compared to pure aramid layers.
    • Multilayer fabric systems incorporating alginate/aramid layers showed enhanced thermal protection performance.

    Conclusions:

    • Alginate/aramid blended waterproof and breathable layers significantly enhance the flame-retardant properties and thermal stability of firefighting suit materials.
    • The integration of these blended layers improves the overall performance and thermal protection capabilities of firefighting apparel.
    • Alginate/aramid blended fabrics represent a promising material for advancing the safety and effectiveness of firefighting clothing.
