  • Patent number: 8585813
    Abstract: Compositions useful for the flame retardant finishing of cotton articles or other cellulose materials are described. The compositions are obtainable by reacting a tetrakishydroxyalkylphosphonium (THP) salt with caprolactam and urea to form a condensation product and subsequently forming a condensate from excess THP salt and excess urea. The compositions endow cotton articles with flame retardant properties and a pleasantly soft hand coupled with good durability to laundering processes.

  • Patent number: 7776179
    Abstract: The present invention imparts fire-retardancy upon cellulosic products utilizing a cost-effective, non-toxic, and reliable process. Unlike previous methods which impart superficial fire-retardant coatings upon finished products, the present process treats the individual cellulosic particles (i.e. fibers, chips etc.) that make up cellulose-based particle products. Treating the individual particles provides fire-retardancy throughout the entire length and width of the product. This full-depth retardancy provides superior protection, especially in catastrophic fires where the surface coat of other products can be compromised.

  • Patent number: 6491727
    Abstract: Compositions and methods of rendering cellulosic materials flame resistant, and articles of manufacture including the materials, are disclosed. The compositions include one or more crosslinking agents, and, optionally, one or more phosphorus-based compounds. Dimethyloldihydroxyethylene urea, imidazole, imidazolidinones, dialdehydes, and dichlorotriazines are preferred crosslinking agents. The methods involve applying the composition to the material, and covalently linking the crosslinking agent to the material. An advantage of covalently linking the crosslinking agent to the cellulosic material is the lack of any potential toxicity associated with uncrosslinked fire retardants on the cellulosic material and the stability of the bonds between the material and the crosslinking agent to conventional steam cleaning and other carpet cleaning methods. In a preferred embodiment, the fire-retardant cotton-fiber composition is used to prepare cotton carpets, upholstery or raised surface apparel.

  • Patent number: 6488718
    Abstract: Compositions and methods of rendering cellulosic materials fire retardant, and articles of manufacture including the materials, are disclosed. The compositions include an amino acid, protein and/or peptide and optionally include one or more crosslinking and/or coupling agents. Enzymes are a preferred protein. The methods involve applying the composition to the material, and optionally involve covalently linking the amino acid, protein and/or peptide to the material, either directly or via a crosslinking agent. An advantage of covalently linking the amino acid, protein and/or peptide to the cellulosic material is the lack of any potential toxicity associated with breathable dust particles of unbound amino acid, protein and/or peptide, and the stability of the bonds between the material and the amino acid, protein and/or peptide to conventional steam cleaning and other carpet cleaning methods.

The polymeric composition may include VPA, VDPA or hypophosphorous acid. The fibres may be cellulosic and/or non-cellulosic, or metal or ceramic. The method can be used, for example, to enhance the receptivity of a fibrous substrate to dyes.

  • Patent number: 6336943
    Abstract: The present invention is generally directed to a process for making fabrics containing cotton fibers more aesthetically pleasing and resistant to staining by anionic dyes by derivatising the cotton so that it exhibits a permanent anionic charge. By increasing the anionic charge of the fibers, the fibers become resistant to anionic coloring agents which may undesirably come into contact with the fibers and the fibers can absorb greater amounts of cationic softeners and biocides. Furthermore, the negative charges repel each other resulting in a fabric with greater loft and hydrophilicity. This results in greater smoothness, better hand, and more comfort. Besides being used to prevent the cross-staining of fabrics, the present invention can also be used to make carpet materials resistant to anionic staining agents.

    Abstract: An aqueous finishing composition for cellulose-containing materials, comprising a hydroxyalkyl-functional organophosphorus flame retardant (which contains a substantially non-volatile component at the curing temperature) and a non-formaldehyde cross-linking agent (such as a polycarboxylic acid cross-linking agent), and the materials treated with such a composition. Optional ingredients for the aqueous finishing composition include a cross-linking catalyst and/or an inexpensive saturated alpha-hydroxy polycarboxylic acid such as citric acid (partial replacement of a more expensive preferred polycarboxylic acid will reduce finishing costs).
