Bio-based, nontoxic and flame-retardant cotton/alginate blended fibres as filling materials: Thermal degradation properties, flammability and flame-retardant mechanism

摘要

The effect of the blending amount of alginate fibres to cotton fibres on thermal stabilities, surface micromorphologies, flame-retardant and combustion properties of prepared cotton/alginate blended fibres were explored. The alginate fibres improved the thermal degradation properties at a higher temperature zone, showing in the increase of the residual chars. The alginate fibres enhanced flame-retardant properties and fire behaviors of prepared cotton/alginate blended fibres. The alginate fibres obviously decreased total heat release, peak heat release rate, total smoke production, CO2 production, and the released amount of inflammable volatiles. And the flame-retardant properties of cotton/alginate blended fibres can meet the requirements of filling materials for indoor furniture.
