    • Fabric is padded with a solution of nitrogen rich N-methylol crosslinking agent, acid catalyst, antimony oxide and a halogen containing alcohol; dried at about 140.degree.-190.degree. F. and then cured at about 250.degree.-400.degree. F. for sufficient time to impart smooth-dry and flame retardant properties to said fabric. Aqueous polyethylene or silicone emulsion softeners can be added to the padding solution if desired. Glycol, polyol and dibromoneophentyl glycol make exemplary halogen containing alcohols. The process can also be varied to first pad with antimony oxide, dry, and then repad with a solution of: nitrogen rich N-methylol crosslinking agent, acid catalyst, and a halogen containing alcohol, dry again and cure, at the temperatures specified supra.
    • 织物用富氮的N-羟甲基交联剂,酸催化剂,氧化锑和含卤素的醇的溶液填充; 在约140°-190°F干燥,然后在约250°-400°F下固化足够的时间以赋予所述织物平滑干燥和阻燃性能。 如果需要,可以将水性聚乙烯或硅氧烷乳液软化剂加入到填料溶液中。 乙二醇,多元醇和二溴香酚二醇制备示例性的含卤素醇。 该方法也可以变化,首先用氧化锑填充,干燥,然后用富氮的N-羟甲基交联剂,酸催化剂和含卤素的醇的溶液重新分离,再次干燥并在上述规定的温度下固化 。

    • Flame-retardant antistatic polymer additives are provided which inhibit the buildup of electrostatic charges upon the addition of such compositions to synthetic polymeric fibers, i.e., polyamide fibers, and at the same time do not contribute to the flammability characteristics of such polymeric fibers. The flame-retardant antistatic polymer compositions are useful in combinations with fibers such as polyamide, polyester, polyurea, polyurethane, polysulfonamide, polyolefin and polyacrylic fibers. The antistatic effect is obtained by the process of coating the fibers or dispersing in or on the fibers up to about 12 percent by weight of a polymer composition which is the reaction product of:(a) a polyoxyalkylene compound or polyester thereof and(b) at least one reactant selected from the group consisting of (1) a diol, (2) a polyester and (3) an aliphatic or aromatic diacid or derivative of (3), wherein at least one said reactant is halogenated.Improved flame-retardant properties can be obtained by including with the flame-retardant, antistatic polymer composition an effective flame retardant proportion of a compound from group Vb of the periodic table. Generally about 1:4 to about 4:2 parts halogen to antimony compound is used. Such compounds are oxides of metals such as phosphorus, arsenic, antimony, or bismuth with the preferred compound being antimony trioxide.
    • 提供了阻燃抗静电聚合物添加剂,其在将合成聚合物纤维即聚酰胺纤维加入这些组合物时抑制静电荷的累积,并且同时不影响这种聚合物纤维的可燃性。 阻燃抗静电聚合物组合物可与纤维如聚酰胺,聚酯,聚脲,聚氨酯,聚磺酰胺,聚烯烃和聚丙烯酸纤维组合使用。 抗静电效果是通过将纤维涂布或分散在纤维中或在纤维上分散至约12重量%的聚合物组合物获得的,聚合物组合物是以下物质的反应产物:(a)聚氧化烯化合物或其聚酯和(b) 至少一种选自(1)二醇,(2)聚酯和(3)脂族或芳族二酸或(3)的衍生物的反应物,其中至少一种所述反应物被卤化。 通过使阻燃抗静电聚合物组合物包含有效的阻燃比例的元素周期表中的Vb族化合物,可以获得改进的阻燃性能。 通常使用约1:4至约4:2份卤素至锑化合物。 这些化合物是金属的氧化物,例如磷,砷,锑或铋,优选的化合物是三氧化锑。
