Abstract
Smolder resistance is imparted to cotton and cotton-containing fabrics by applying a certain boron-nitrogen-phosphorus system to the fabric, employing conventional equipment. An inorganic boron compound is placed in solution with a phosphorus-containing compound, then a nitrogen-containing compound is added. The aqueous mixture is applied using conventional textile equipment, dried, and cured by standard methods.
