Abstract
Synthetic textile articles (e.g., filaments, fibers, yarns, fabrics and the like) and processes of making the same are provided which include flame-retardant SAP particles. The SAP particles are most preferably hydrated with an aqueous flame-retardant solution. In this regard, the flame-retardant solution may consist essentially of water alone or a water solution containing one or more water soluble inorganic flame retardants. When SAP particles are hydrated with an aqueous inorganic flame retardant solution, the SAP particles may thereafter be dried to remove substantially the water component. In such a manner, the inorganic flame retardant will remain as a dried residue physically entrained within the SAP particles. As such, the SAP particles serve as a physical matrix in which the inorganic flame retardant is homogenously dispersed. The SAP particles may then be chemically or physically affixed to the textile article in an amount sufficient to render the article flame-retardant.
