Abstract
Compositions useful for the flame retardant finishing of cotton articles or other cellulose materials are described. The compositions are obtainable by reacting a tetrakishydroxyalkylphosphonium (THP) salt with caprolactam and urea to form a condensation product and subsequently forming a condensate from excess THP salt and excess urea. The compositions endow cotton articles with flame retardant properties and a pleasantly soft hand coupled with good durability to laundering processes.
