Summary
This study developed a novel fire-retardant coating for cotton fabric using a layer-by-layer method. The enhanced coating significantly improved the fabric
Area of Science:
- Materials Science
- Textile Engineering
- Fire Safety Engineering
Background:
- Textile fabrics are prevalent in high-tech industries, posing fire risks.
- Developing effective fire-retardant treatments for textiles is crucial for safety.
Purpose of the Study:
- To develop a novel fire-retardant coating for cotton fabric.
- To investigate the efficacy of a layer-by-layer deposition method using chitosan, polyethyleneimine, and bentonite clay.
Main Methods:
- Utilized a novel layer-by-layer deposition technique.
- Employed a hybrid cationic solution (chitosan and branched polyethyleneimine) and anionic bentonite clay.
- Characterized the treated fabric using SEM, EDS, FTIR, and TGA.
Main Results:
- Confirmed successful deposition of the coating using SEM and EDS.
- FTIR analysis indicated significant changes in chemical composition.
- Thermogravimetric analysis showed a residue of ~19.83% at 700 °C, indicating improved thermal stability.
Conclusions:
- The novel layer-by-layer method effectively created a fire-retardant coating on cotton fabric.
- The developed coating significantly enhances the thermal stability and fire resistance of cotton textiles.
