Patent number: 5104416Abstract: In the conventional methods for the preparation of printing pastes containing couplable diazonium compounds, liquid bases, sodium nitrite and phosphoric acid are incorporated separately in succession in the thickener or they are each prepared as separate thickeners and then combined with stirring only when they are used. Such measures are relatively complicated and are therefore considered as a disadvantage in practice. If the acids customary for the diazotization are used, there is a further risk that the fixation by steaming of the reactive dyes printed in addition to the diazo components will be impaired.This situation considered problematical by persons skilled in the art can be remedied by using liquid water-based preparations of diazotizable amines which, in addition to the amine, simultaneously contain the amount of acid necessary for its diazotization in the form of, preferably, phosphoric acid.Type: GrantFiled: September 27, 1990Date of Patent: April 14, 1992Assignee: Hoecht AktiengesellschaftInventor: Horst-Roland Mach

Patent number: 4752299Abstract: A process for dyeing a mixed fibrous substrate comprising applying to the substrate at least one disperse dye and at least one metal containing direct and/or reactive dye in the presence of a complexing agent having a stability constant K value with the metal of the direct or reactive dye of from 6 to 17 inclusive.Type: GrantFiled: October 23, 1986Date of Patent: June 21, 1988Assignee: Sandoz Ltd.Inventors: Oskar Annen, John A. Hook

Patent number: 4752300Abstract: Poly(m-phenyleneisophthalamide) fibers are simultaneously dyed and imparted improved flame retardant properties with a fire retardant liquid in which a disperse or acid dye is dissolved. Fabrics thus dyed and FR treated exhibit no afterglow when exposed to an open flame and a Limiting Oxygen Index greater than their undyed counterparts.Type: GrantFiled: June 6, 1986Date of Patent: June 21, 1988Assignee: Burlington Industries, Inc.Inventor: James R. Johnson

Patent number: 4750911Abstract: Nylon/cotton fabrics are fire retarded with a flame-retardant cyclic phosphonate ester and tetrakis-(hydroxymethyl)phosphonium sulfate (THPS), usually applied simultaneously, then cured. The resulting fabrics retain their flame-resistant properties after numerous machine washings and have an acceptable hand.Type: GrantFiled: September 26, 1986Date of Patent: June 14, 1988Assignee: Burlington Industries, Inc.Inventors: John H. Hansen, James R. Johnson

Patent number: 4749378Abstract: Aramid fibers, polybenzimidazole fibers or blends of aramid and polybenzimidazole fibers are rendered flame resistant by a flame retardant introduced into the fibers by a polar organic swelling agent such as DMSO. Dyed or undyed fibers so treated exhibit substantially improved flame resistance as compared with untreated fibers.Type: GrantFiled: September 12, 1986Date of Patent: June 7, 1988Assignee: Burlington Industries, Inc.Inventors: Barbara J. Cates, Tanya E. FitzGerald, James K. Davis, Ernest J. Russell
