Patent number: 4334877Abstract: Foamable fabric treatment compositions are disclosed which are composed of a fabric finishing agent and a foam stabilizer, which compositions are capable of forming a foam having a blow ratio in the range from about 2:1 to 20:1 and a foam density range from about 0.5 gm/cc to 0.05 gm/cc. Methods for preparing and using the foamable compositions are disclosed. Included in the composition is up to about 10 percent of foam stabilizer.Type: GrantFiled: February 20, 1980Date of Patent: June 15, 1982Assignee: United Merchants & Manufacturers Inc.Inventors: Razmic S. Gregorian, Chettoor G. Namboodri

Patent number: 4311855Abstract: An improved process for manufacturing tetrakis (hydroxymethyl) phosphonium amide condensation product without the formation of a precipitate. Urea or thiourea is added to the tetrakis (hydroxymethyl) phosphonium salt having an anion formed from a dibasic or tribasic or polybasic acid. The said salt is in aqueous solution. The pH of the aqueous solution of said salt is adjusted to the range of 4-6.5 when the urea or thiourea is added to the salt. The proportion of said salt to said urea or thiourea is 1:0.05-0.5 (molar). The sulphuric acid salt is preferred. The process produces an improved aqueous product substantially free of insolubles.Type: GrantFiled: January 25, 1980Date of Patent: January 19, 1982Assignee: Albright & Wilson Ltd.Inventors: Robert Cole, James E. Stephenson

Patent number: 4279652Abstract: A new composition is described comprising a synthetic, artificial or natu polymer and a flameproofing additive imparting self-extinguishing properties to the composition and to the articles, such as moulded, spun or woven articles, made therefrom, said additive being the product of the reaction of melamine with acidic compounds, such as organic acids or anhydrides and inorganic acids. The process for making said additive by said reaction, preferably in the presence of water, is also described. The said composition may be made by introducing said additive in any manufacturing stage, viz. to the monomers (if the polymer is a synthetic one), to the molten polymer, to polymer solutions such as viscose dope, to polymer chips during extrusion, or to finished products e.g. by applying a finish to fabrics.Type: GrantFiled: September 15, 1977Date of Patent: July 21, 1981Assignee: Sniaviscosa Societa Nazionale Industria Applicazioni Viscosa, S.p.A.Inventors: Aldemaro Ciaperoni, Antonino Cucinella
