Abstract: 2,4-Diamino-6(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-diamino-6(3,3,3-trichloro-1-propyl)-1,3,5-triazine were prepared by the reaction of the corresponding methyl or ethyl .gamma.-tribromo-butyrate or methyl or ethyl .gamma.-trichlorobutyrate with biguanide. The N-methylol derivatives of the diaminotrihalopropyl triazines were prepared by the reaction of the triazines with aqueous formaldehyde. Two pure tetramethylol derivatives were prepared, namely: 2,4-bis[bis(hydroxymethyl)amino]-6-(3,3,3-tribromo-1-propyl)-1,3,5-triazin e and 2,4-bis[bis(hydroxymethyl)amino]-6-(3,3,3-trichloro-1-propyl)-1,3,5-triazi ne. The tetramethylol derivatives were used to impart durable flame retardancy and wrinkle recovery to cellulosic textiles, particularly to cotton. Flame-retardancy was also imparted to wool and to blends of cotton and polyester.

Abstract: 2,4,6-Tris(carbamoylmethylamino)-1,3,5-s-triazine, abbreviated TCMT, is prepared by the reaction of 2,4,6-tris(carbethoxymethylamino)-1,3,5-s-triazine with ammonia. The methylol derivative of TCMT is prepared and applied to cotton textiles and blends of cotton and polyester to impart wrinkle recovery thereto.

Abstract: The tetramethylol derivatives of 2,4-diamino-6(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-diamino-6(3,3,3-trichloro-1-propyl)-1,3,5-triazine, namely: 2,4-bis[di(hydroxymethyl)amino]-6-(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-bis[di(hydroxymethyl)amino]-6-(3,3,3-trichloro-1-propyl)-1,3,5-triazin e, respectively, were used in combination with colloidal antimony oxides and or water emulsifying agents and suitable solvent to impart durable flame-retardancy to cellulosic materials, protein fibers such as wool, and to blends of cellulosic materials and synthetic fibers, particularly to cotton textiles or textiles composed of blends of cotton and polyester. Afterglow was eliminated by the use of small amounts of reactive phosphorus compounds.
