Key Findings

01The phytic acid and biochar treatment significantly reduced the peak heat release rate and total heat released by cotton fabric under radiative heat flux.
02Treated fabrics showed improved flame retardant behavior compared to untreated cotton, even after washing, although washing reduced the overall effectiveness.
03The treatment promoted the formation of a stable char layer, which acts as a barrier against heat and oxygen.

Application

Design takeaway

Consider bio-sourced flame retardant treatments like phytic acid and biochar for cotton products where fire safety is critical, while also addressing wash durability in the design process.

How to apply

Incorporate phytic acid and biochar into the finishing process for cotton upholstery, apparel, or technical textiles where flame resistance is a requirement.

Project actions

01When researching flame retardants, look for studies that use sustainable or bio-based materials.

Method & Evidence

AimTo investigate the effectiveness of a bio-sourced flame retardant formulation (phytic acid and biochar) on cotton fabric's flammability properties.

MethodExperimental testing and material analysis

ProcedureCotton fabrics were treated with a solution containing phytic acid and biochar. The treated fabrics were then subjected to various flame retardancy tests, including cone calorimetry to measure heat release and limiting oxygen index (LOI) tests to determine the minimum oxygen concentration required for combustion. The morphology of the char layer formed during combustion was also analyzed.
