Patent number: 4151316Abstract: Polyethylene terephthalate fiber-containing fabric is flameproofed by application of an aqueous suspension of finely divided particles consisting essentially of octagonal hexabromide formed by the incomplete bromination of cis, trans, trans cyclododecatriene to provide a mixture having a melting point in the range of 177.degree.-191.degree. C. determined by differential scanning colorimetry using a heating rate of 10.degree. C. per minute. The treated fabric is dried and then heated with the octagonal hexabromide particles thereon to a temperature above the melting point of the mixture, but not in excess of about 200.degree. C. for a period long enough to achieve adequate penetration (30 seconds), to cause the hexabromide particles to diffuse into the fibers of the fabric to maximize fire resistance and obtain proper fixation of the particles to the fabric in a manner providing durability to laundering with minimum damage to the fabric.Type: GrantFiled: November 9, 1977Date of Patent: April 24, 1979Assignee: Chas.

Patent number: 4098986Abstract: Copolymerizable monoethylenic phosphites are produced by reacting an N-methylol allyl carbamate with a stoichiometric excess of a trialkyl phosphite. The monoethylenic phosphonate product can be copolymerized, especially with N-methylol acrylamide in water solution to provide water solutions of copolymers which cure at low temperature on cellulosic fabrics to provide fire retardancy and the phosphorus provided in this fashion resists removal by washing and dry cleaning.Type: GrantFiled: March 31, 1976Date of Patent: July 4, 1978Assignee: Chas. S. Tanner Co.Inventor: Martin K. Lindemann
