Abstract: A process for the flame-retardant treatment of a cellulosic fabric by impregnating a fabric with an aqueous solution of a tetrakis (hydroxyorgano) phosphonium (THP) and then at least partially drying it. The partially dried impregnated fabric is passed at a speed of 30 to 100 m/minute once through a chamber containing ammonia for a single cure. Both the moisture contained in the fabric and water produced as a by-product of curing are volatilized and condensed on an interior wall of the chamber and flow down the walls to a drain for removal of the condensed water from the apparatus. The process further includes measuring the rate of ammonia in the gas fed into the chamber, determining the ammonia content of the gas and measuring the temperature within the chamber, for maintaining the initial concentration of ammonia in the gas at 70% to 90% by volume and for maintaining the ratio of ammonia input to the THP composition in the range of at least 1.

Abstract: In the process for rendering textile materials, especially cellulose-containing tent fabrics, fire-resistant by condensing dicyandiamide with formaldehyde and phosphoric acid, followed by dilution with water and application to the fabric, it has been found that the need to dilute the condensate and apply it promptly after formation can be avoided provided additional phosphoric acid is added from about 0 to 8 hours prior to the dilution. Without such additional phosphoric acid, if the dilution is later effected an insoluble precipitate will form. Thus, the invention permits production and shipping of a clear solution which, to be used, need only be diluted first with additional phosphoric acid and then with water. The initial condensation is preferably effected with about 0.9-3 moles of formaldehyde per mole of dicyandiamide in aqueous solution at a pH of about 8 to 13 and thereafter about 0.06-0.6 mole of phosphoric acid per mole of dicyandiamide and at least about 0.

Abstract: A process is described for obtaining finishing effects on textile material consisting, at least partially, of cellulose fibers, without seriously reducing the tensile strength, tearing strength or wearing strength of the fibers. A finishing agent, capable of cross-linking with the hydroxy groups of the cellulose fibers, in a solution or emulsion containing a mixture of water and at least one organic solvent, such as low aliphatic ketones, aliphatic chlorinated hydrocarbons or low aliphatic esters, is applied to the textile material. The stability of the mixture is controlled by a salting-in or salting-out effect so as to induce a phase separation between aqueous and solvent phase, this effect being induced by the use of neutral salts, acid salts, potentially acid salts, organic acids, synthetic resins or reactants. The finishing agent is concentrated in the aqueous phase in the interior of the individual fibers while the surface zones retain the good surface properties of the starting material.

Abstract: In mild cure finishing, strong catalysts are required because of the modest curing conditions employed in the process. Suitable catalysts for mild cure finishing include strong inorganic acids, strong organic acids, active inorganic complexes, salt/acid combinations, and salts that are strong Lewis acids (i.e, certain metal salts). Ammonium salts of inorganic acids, although often used in other types of treatments for producing wrinkle resistant textiles, are not satisfactory catalysts for mild cure finishing. Unexpectedly and surprisingly, it has been discovered that ammonium salts of certain, but not all, sulfonic acids can serve as effective catalysts for mild cure finishing of cellulose-containing fabrics to produce wrinkle resistance and durable press properties. Among ammonium sulfonates which provide the catalysis needed for mild cure finishing are ammonium methanesulfonate, ammonium carboxymethanesulfonate (NH.sub.4 O.sub.3 SCH.sub.2 COOH), ammonium benzenesulfonate, and ammonium p-toluenesulfonate.
