Method of application of THPOH-NH{HD 3 {B fire retardant finish to textiles |
| abstract |
Fire resistance has been imparted by the application of an aqueous solution of tetrakis (hydroxymethyl) phosphonium hydroxide (heretofore referred to as THPOH) followed by heat drying to 2 to 8% moisture content; polymerizing, wholly or partially, the phosphorus compound in the cellulosic textile with ammonia gas in low concentration at about 65* to 95*C for 5 to 90 seconds; then rinsing in cold water, or completing the polymerization with dilute NH4OH; oxidizing the phosphorusnitrogen containing polymer; washing and drying. This invention provides an improved process for the production of fire resistant textiles, by accelerating the polymerization reaction and causing the overall process to be more adaptable to a continuous process. The finish is durable to repeated launderings. |
