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.

What is claimed is: 1. A flame-retardant synthetic textile article comprising a textile article, and a flame-retardant effective amount of flame-retardant superabsorbent polymer (SAP) particles which are comprised of SAP particles and an amount between about 25 wt. % to about 500 wt. %, based on th
What is claimed is: 1. A flame-retardant synthetic textile article comprising a textile article, and a flame-retardant effective amount of flame-retardant superabsorbent polymer (SAP) particles which are comprised of SAP particles and an amount between about 25 wt. % to about 500 wt. %, based on the total weight of the flame-retardant SAP particles, of an inorganic flame retardant absorbed by and physically entrained within the SAP particles. 2. The flame-retardant article of claim 1, wherein the flame-retardant SAP particles comprise SAP particles hydrated with an aqueous inorganic flame-retardant solution absorbed by and physically entrained within the SAP particles. 3. The flame-retardant article of claim 1, wherein the flame-retardant SAP particles comprise a dried residue of an aqueous inorganic flame retardant solution absorbed by and physically entrained within the SAP particles. 4. The flame-retardant article as in claim 1, wherein the inorganic flame retardant includes at least one phosphorus-containing flame retardant. 5. The flame-retardant article as in claim 4, wherein the phosphorus-containing flame retardant is at least one selected from the group consisting of phosphoric acid and sodium salt derivatives thereof, phosphorous acid and sodium salt derivatives thereof, ammonium orthophosphate, ammonium hypophosphate, ammonium hydrogen phosphate, ammonium dihydrogen phosphate, ammonium hypophosphite, and ammonium dihydrogen orthophosphite. 6. The flame-retardant article as in claim 1, wherein the inorganic flame retardant is at least one selected from the group consisting of boric acid, sodium tetraborate and hydrates thereof, sodium metaborate and hydrates thereof, and zinc borate. 7. The flame-retardant article as in any one of claims 1-6, wherein the inorganic flame retardant is present in an amount of between about 25 wt. % to about 200 wt. %, based on the total weight of the flame-retardant SAP particles. 8. The flame-retardant article as in claim 1, wherein the flame-retardant SAP particles comprise hydrated SAP particles. 9. The flame-retardant article of claim 1, wherein the article is in the form of a synthetic filament, fiber, yarn or fabric. 10. A method of making a flame-retardant synthetic textile article comprising affixing an effective amount of flame-retardant superabsorbent polymer (SAP) particles to the textile article, wherein the flame-retardant SAP particles comprise SAP particles and an amount between about 25 wt. % to about 500 wt. %. based on the total weight of the flame-retardant SAP particles, of an inorganic flame retardant absorbed by and physically entrained within the SAP particles. 11. The method as in claim 10, wherein the flame-retardant SAP particles are comprised of SAP particles containing a dried residue of an aqueous inorganic flame retardant solution. 12. The method as in claim 10, comprising chemically binding the flame-retardant SAP particles to the textile article. 13. The method as in claim 10, comprising binding the flame-retardant SAP particles to the textile article with a binder resin. 14. The method as in claim 10, comprising entrapping the flame-retardant SAP particles within interstices of the textile article. 15. The method as in claim 11, wherein the inorganic flame retardant includes at least one phosphorus-containing flame retardant. 16. The method as in claim 15, wherein the inorganic flame retardant is at least one selected from the group consisting of phosphoric acid and sodium salt derivatives thereof, phosphorous acid and sodium salt derivatives thereof, ammonium orthophosphate, ammonium hypophosphate, ammonium hydrogen phosphate, ammonium dihydrogen phosphate, ammonium hypophosphite, and ammonium dihydrogen orthophosphite. 17. The method as in claim 11, wherein the inorganic flame retardant is at least one selected from the group consisting of boric acid, sodium tetraborate and hydrates thereof, sodium metaborate and hydrates thereof, and zinc borate. 18. The method as in any one of claims 10-17, wherein the inorganic flame retardant is present in an amount of between about 25 wt. % to about 200 wt. %, based on the total weight of the flame-retardant SAP particles. 19. The method as in claim 10, wherein the article is in the form of a synthetic filament, fiber, yarn or fabric.
