Delayed Flammability for Natural Fabrics by Deposition of Silica Core-Amine Shell Microspheres through Dip-Coating Process

In this study, we synthesized a SiO2-APTES core-shell microsphere (Si-NH2-MS) flame retarding material (FRM) as a heat shielding layer on natural fabrics, such as jute, cotton, and flax(cellulose) fibers. This integration was made to improve the flame retardancy property of pure jute, pure cotton, a...
