Flammability Procrastination Obtained for the Natural Fabrics by Deposition of Silica Core-Amine Shell Microspheres through Dip-Coating Process | Chapter 2 | Novel Perspectives of Engineering Research Vol.7

 We created a SiO2-APTES core-shell microsphere (Si-NH2-MS) flame retarding material (FRM) to use as a heat shielding layer on natural fabrics including jute, cotton, and flax(cellulose) fibres in this work. This integration was made to boost the flame retardancy property of pure jute, pure cotton, and pure flax fibres by dip-coating deposition of charged anionic and cationic polyelectrolytes to generate thin multilayer coatings on the surface of the fabrics via electrostatic interactions. Furthermore, a strong bonding process occurs between the fabric surface and Si-NH2-MS via interionic interactions. Pure jute, cotton, and flax fibres burnt entirely in 14, 12, and 10 seconds, respectively, whereas 2 wt percent Si-NH2-MS treated jute, cotton, and flax fibres took 21, 18, and 15 seconds to burn completely. Furthermore, due to the thermal insulation layers developed by the proposed Si-NH2-MS, which were coated uniformly on the surface of the fibres with the help of covalent bonds, 5 wt percent Si-NH2-MS treated jute, cotton, and flax fibres showed delayed burning times of 48, 41, and 23 s, respectively, due to the proposed Si-NH2-MS, which were coated uniformly on the surface of the fibres with the help of covalent bonds. In addition, fabrics coated with 5 wt percent Si-NH2-MS showed ignition resistance and self-extinguishing abilities, which could be a significant benefit for interior fire quenching applications.

The current findings point to a stronger flame retardancy property that allows for increased HRR and heat-flow effects, resulting in a high-performance, next-generation flame-retardant material. We intend to investigate next-generation, high-performance, flame-retardant materials with economic feasibility based on the current positive results.
