Abstract
This invention consists of a novel flame retardant, its method of manufacture and its application to textile fabrics in order to render fabrics flame retardant. The flame retardant compound produced can be applied by padding it onto the fabric and it provides a durable flame retardant which will not support combustion.
Claims3
The process of flame retarding non-cellulosic fabrics comprising the steps of:
- raising the pH of a flame retardant containing the chemical compound:
- ##STR4## where:
- x=1-250, R is selected from the group:
- --H, --OH, --NH.sub.3 or --COOH
- by adding a water soluble basic compound to thereby increase the water solubility of said flame retardant, padding the fabric with said basic flame retardant solution, absorbing 2-10% dry flame retardant, removing the fabric from the flame retardant solution and fixing said flame retardant to the fabric.
