    摘要: Fibrous material such as cotton cloth is simultaneously rendered flame retardant and imparted improved dimensional stability by treating the material with cyanamide and at least one phosphonic acid represented by the structural formula:

    wherein R1 represents a divalent organic radical such as methylene or ethylene, X represents a covalent bond, -POOR3- or CO-; and R2 and R3 represent a monovalent radical such as hydrogen or methyl. Mixtures of these phosphonic acids with other phosphonic acids such as methyl phosphonic acid can give particularly advantageous results. Durability of the flame retardancy to repeated hard water washing may be improved through a subsequent treatment with additional cyanamide, with N-methylol compounds, or by methylation with diazomethane. Durable press properties of cellulosic textiles are also improved by the subsequent treatment with additional cyanamide. A particularly high degree of flame retardancy is imparted to mercerized cotton cloth.

    摘要: WHEREIN R1 represents a monovalent radical such as hydrogen or methoxy and R2 represents a monovalent radical such as hydrogen or methyl. Durability of the flame retardancy to repeated hard water washing may be improved through a subsequent treatment with N-methylol compounds or with additional cyanamide or by methylation with diazomethane. Dimensional stability and durable press properties of cellulosic textiles are also improved by the subsequent treatment with additional cyanamide. A particularly high degree of flame retardancy is imparted to mercerized cotton cloth.

    摘要: Fibrous material such as cotton cloth is rendered flame retardant by treating the material with cyanamide and at least one halomethyl phosphonic acid represented by the structural formula:

    wherein R1 represents a monovalent radical such as chloro or bromo and R2 represents a monovalent radical such as hydrogen or methyl. Durability of the flame retardancy to repeated hard water washing may be improved through a subsequent treatment with Nmethylol compounds such as methylolated melamine precondensate. A particularly high degree of flame retardancy is imparted to mercerized cotton cloth.
