Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
73 words
A process for preparing cellulosic, cellulosic blend or synthetic fiber fabric having flame retardancy and durable-press properties comprising: a. wetting a cellulosic, cellulosic blend or synthetic fiber fabric in an aqueous solution containing tetrakis(hydroxymethyl) phosphonium chloride, a nitrogeneous containing compound selected from the group consisting of a N-methylol acrylamide and an acrylamide, and a vinyl monomer selected from the group consisting of methylenebisacrylamide and 1,3,5,tri-acryloylhexahydro-s-triazine; and b. curing the treated fabric from (a).
Claim 2
Dependent Claim
