for about 1 to about 10 minutes to promote drying the materials are then cured in a circulating air oven at about 250 u00b0 to 450 u00b0 f or preferably from about 300 u00b0 to 370 u00b0 f for about 1 to 10 minutes to promote reaction drying and curing may be completed in one step but a separate dry and cure is preferable thereafter the samples are washed in hot water to remove residual unreacted material and dried the flame retardant agents of this invention may be applied to various textiles such as cellulosic materials proteinaceous materials and blends of cellulosic or proteinaceous materials with polyethylene terephthalate and analogous man made fibers by cellulosic materials applicant intends to embrace cotton rayon paper regenerated cellulose and cellulose derivatives which retain a cellulose backbone of at least one hydroxy substituent per repeating glucose unit by proteinaceous material applicant intends to embrace those textile materials comprising the functional groups of proteins such as the various animal wools hairs and furs of special interest is the applicability of fire retardant agents of the instant invention to analogous man made fibers such as blends of cotton polyethylene terephthalate in textile fabrics and fibers to provide a uniform flame retardant finish it should be noted that it is within the scope of the present invention to incorporate such ingredients as plasticizers dyes pigments stabilizers antioxidants antistatic agents and the like to the novel flame retardant composition in each of the examples the process steps were performed as follows except where a specific method is otherwise indicated padding was accomplished by dipping the sample in the requisite solution for about a second and immediately thereafter nipping the thus treated sample on a two role laboratory padder at about 60 pounds per square.
