  • Patent number: 8597733
    Abstract: Polymeric formulations which contain aqueous dispersions of acrylic monomers and copolymers and modified polyethylene terephthalate resin are disclosed which are useful as a coating system or treatment for imparting water, oil and grease resistance to underlying cellulosic substrates. The formulations do not contain any fluorochemicals, polyethylene or wax. Moreover, the formulations provide water, oil and grease resistance properties that are an improvement in the art to known coatings and treatments which contain polyethylene and or wax for water, oil and grease resistance. These coatings can also impart improved anti-wicking properties over the existing art. These formulations have interest as they contain components that are permitted to come into direct contact with food products. Therefore, the formulations of the present invention are ideal for use as coatings for paper and paperboard, including paper packaging such as that utilized in food wrappers, food containers, food receptacles, etc.

  • Patent number: 8445072
    Abstract: A method of treating wooden parts is described in which a) the wooden parts are impregnated with an aqueous cyanamide solution and subsequently b) the impregnated wooden parts, where appropriate after drying, are subjected to a heat treatment of 130 to 250° C. Here it has surprisingly emerged that impregnation with cyanamide even in small amounts has a significantly positive influence on the performance properties of the treated wooden parts, such as high hardness, low water absorption and very good weathering stability, for example. Moreover, only small amounts of a toxicologically and environmentally unobjectionable impregnating agent are needed in order to obtain these advantageous properties.

Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the dryer section or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.

  • Patent number: 7736696
    Abstract: A closed-loop system and process is used for applying fire retardant chemicals to substrates including fibers, yarns, fabrics or mixtures thereof. Substrates are preferably positioned in a vessel such as a dye machine which circulates the fire retardant chemicals. After absorption of the fire retardant composition, non-absorbed fire retardant chemicals are recovered and re-used on subsequent batches of fibers. The re-use of fire retardant chemicals can take place in the same vessel which is used to treat successive batches of substrates. Alternatively, recovery can be achieved by directing the non-absorbed fire retardant composition into a second dye machine containing additional fibers, or by extracting the fire retardant composition by centrifugation or other means, or by a combination of the two processes. The process is environmentally friendly, and allows for higher throughput on impregnating fibers with fire retardant chemicals.

  • Patent number: 7592048
    Abstract: A photocatalytic substrate comprises a textile support and a finish on the surface thereof. The finish on the surface of the textile support comprises a particulate photocatalytic material and a binder. A process for producing a photocatalytic substrate comprises the steps of providing a textile support having at least one surface, providing a coating composition, applying the coating composition to at least a portion of the surface of the textile support, and drying the surface of the textile support to which the coating composition was applied to produce a photocatalytic substrate.

  • Patent number: 7438951
    Abstract: The present invention relates to a crosslinked aqueous solution polymer composition consisting of about 15 wt-% to about 50 wt-% of at least one water soluble monomer, preferably an alpha, beta-ethylenically unsaturated carboxylic acid monomer and a crosslinking agent. The polymer solution is sufficiently low enough in viscosity such that it can be applied in aqueous form, yet after crosslinking possesses a fast rate of acquisition and is high absorption capacity. The invention also relates to new methods of enhancing the absorbency of various articles, increasing the humectancy and/or absorbency of a fiber or fibrous matrix, improving the water retention of soil and other agricultural methods, and increasing the open time of cement by incorporating or applying an aqueous superabsorbent polymer composition.

  • Patent number: 7435483
    Abstract: Disclosed are coated fiber-containing articles, including paper, paperboard, and molded fiber, and methods for preparing such articles. A preferred method comprises heating paperboard containing a polymeric binder to a temperature sufficient to remove at least some moisture from the paperboard; applying an aqueous dispersion or solution of at least one water-dispersible or water-soluble polymer to the paperboard product; heating the paperboard to at least partially cure the water-dispersible or water-soluble polymer; and cooling the paperboard to at least 160° F. to reduce the tackiness of the cured water-dispersible polymer.

  • Patent number: 7211293
    Abstract: A closed-loop system and process is used for applying fire retardant chemicals to fibers. Fibers are preferably positioned in a vessel such as a dye machine which circulates the fire retardant chemicals. After absorption of the fire retardant composition, non-absorbed fire retardant chemicals are recovered and re-used on subsequent batches of fibers. Recovery can be achieved by directing the non-absorbed fire retardant composition into a second dye machine containing additional fibers, or by extracting the fire retardant composition by centrifugation or other means, or by a combination of the two processes. The process is environmentally friendly, and allows for higher throughput on impregnating fibers with fire retardant chemicals.
