Abstract: The instant invention relates to a textile article comprising a flame-retardant treated fabric including an oxidized polymer obtained from an ammonia curing of a condensate of (i) a tetrakis (hydroxyorgano) phosphonium salt; and (ii) urea or thiourea; followed by an oxidation into phosphine oxide groups of at least one part of the phosphonium groups present on the cured condensate, wherein said flame-retardant treated fabric: —is intended to be used as a stable substrate in which the formation of formaldehyde over the time is inhibited; and —contains less than 1% by weight of phosphorus present in phosphonium groups, based on the total weight of the flame-retardant treated fabric.

Abstract: The instant invention relates to a composition useful as a precursor for imparting flame-retardant properties to textile articles, comprising a condensate of: (a) a tetrakis (hydroxyorgano) phosphonium sulfate THPS; (b) urea, or alternatively thiourea; (c) optionally, and preferably, an aliphatic hydroxyl-reactive compound, such an amine wherein said composition has a very low free formaldehyde content, namely of less than 0.1%.
