Patent number: 5252233Abstract: A durable hydrophilic silicone textile finish is produced on cellulose-containing textiles to impart durable hydrophilic softness and durable press properties to the textile. The silicone finish is produced from an aqueous solution of glyoxal, a reactive organomodified silicone copolymer, a glycol and an acidic catalyst. The treating composition is applied to the textile and cured by heating at an elevated temperature to bond the silicone to the cellulose.Type: GrantFiled: June 29, 1992Date of Patent: October 12, 1993Assignee: Union Carbide Chemicals & Plastics Technology CorporationInventor: Anna M.

Patent number: 4472167Abstract: The use of glycols as coreactive additives with glyoxal in the aluminum sulfate-catalyzed crosslinking of cotton cellulose in the presence of alpha-hydroxy acids as catalyst activators at moderate curing temperatures is disclosed. The cotton textiles so treated are free from the discoloration and excessive tendering produced by glyoxal in the presence of metal salt catalysts at high temperature, are non-nitrogenous and formaldehyde-free, and exhibit high levels of wrinkle resistance and smooth drying properties without the formaldehyde release characteristic of N-methylolamide finishing agents.Type: GrantFiled: August 26, 1983Date of Patent: September 18, 1984Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Clark M. Welch

Patent number: 4353707Abstract: A finishing agent for fabrics containing cellulose that is free of formaldehyde is prepared from equimolar amounts of methyl carbamate and glutaraldehyde. The reaction product, although unstable in dilute aqueous solution, can be applied to fabric from concentrated aqueous solution or can be methylated for application from dilute solution. Fabric is given wrinkle-resistance and durable-press properties with no release of formaldehyde from the agent or from the treated fabric.Type: GrantFiled: September 15, 1981Date of Patent: October 12, 1982Assignee: The United States of America as represented by the Secretary of AgricultureInventors: John G. Frick, Jr., Robert J. Harper, Jr.

Patent number: 4304564Abstract: Cotton, or other fabric containing cellulose, is treated with acrylamide and a chemical initiator that promotes reaction of acrylamide with cellulose. The fabric, with bound acrylamide, is then treated with glyoxal and an acidic, metal salt catalyst to produce a fabric containing crosslinked cellulose. Thus, the fabric is given wrinkle resistance and durable-press properties by the treatment without using formaldehyde, free or combined, that could be released during treatment or from the treated fabric.Type: GrantFiled: May 5, 1980Date of Patent: December 8, 1981Assignee: The United States of America as represented by the Secretary of AgricultureInventors: John G. Frick, Jr., Robert J. Harper, Jr.

The fabric is impregnated with a formaldehyde-free finishing agent containing glyoxal, reactive silicone, a catalyst and a buffering agent for reducing the acidity of the fabric. The fabric is thereafter dried and the finishing agent is cured to impart durable press properties to the fabric.Type: GrantFiled: May 7, 1979Date of Patent: May 26, 1981Assignee: Riegel Textile CorporationInventors: Daniel L. Worth, Ernest A. Freeman, Jr.

Patent number: 3989457Abstract: 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.Type: GrantFiled: March 17, 1975Date of Patent: November 2, 1976Assignee: Heberlein & Co.
