Phosphorus Content and Flame Retardant Durability
topic
Phosphorus content in flame-retardant-treated cotton and wool textiles is quantified by ICP-OES after microwave acid digestion, providing a rapid proxy measure for applied phosphorus-based flame retardant concentration; wash durability is assessed by comparing phosphorus content and vertical flame spread performance before and after 50 standardised wash cycles at 60 degrees Celsius.
Role
Validates the wash durability of phosphorus-based flame retardant treatments on cotton nightwear, childrenswear, and institutional textiles by correlating residual phosphorus content with flame performance test outcomes, ensuring that treated fabrics retain adequate fire protection throughout the specified care cycle life of the product.
