Introduction Perfluorinated chemicals (PFCs) have been used widely as surfactants, lubricants, paper and textile coatings, polishes, food packaging, and fire-retarding foams over the past fifty years. Some of these chemicals, such as perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), are persistent in the environment and have been found in wild animal samples around the wor...

n-methylol dimethyl phosphonopropionamide (mdpa) is one of the most utilized fire resistant (fr) finishes for cotton fabrics, utilized as part of a formulation with trimethylol melamine (tmm) to acquire better crosslinking and enhanced fr properties. the system parameters of the finishing treatment were upgraded for better fr properties and low mechanical loss to the fabric by the response surf...
