    • An improvement in a process for imparting flame retardant properties to textile materials by reacting the textile materials with phosphorus-containing compounds or salts thereof and aftertreating the textile material with a salt of a heavy metal is disclosed. In the improved process, the phosphorus-containing compounds are applied in correlation with antimony oxide and a polymeric halogen-containing material. Reduced amounts of phosphorus may be affixed on the textile material (thus substantially reducing fabric shrinkage during processing) without substantially adversely affecting the flame retardant properties of the treated material. Titanyl sulfate is utilized as the heavy metal salt. In addition, the treatment is applicable to cellulosic fibers, e.g., cotton or rayon, as well as to wool, silk and other natural and man-made fibers or blends of these fibers.
    • 公开了通过使纺织材料与含磷化合物或其盐反应并且用重金属的盐对织物材料进行后处理来赋予纺织材料阻燃性能的方法的改进。 在改进的方法中,含磷化合物与氧化锑和聚合物含卤素材料有关。 减少的磷量可以固定在织物材料上(因此在加工过程中基本上减少了织物收缩),而基本上不利地影响了处理过的材料的阻燃性能。 硫酸硫酸盐用作重金属盐。 此外,该处理可应用于纤维素纤维,例如棉花或人造纤维,以及羊毛,丝绸和其他天然和人造纤维或这些纤维的混合物。
