  • Patent number: 7494512
    Abstract: This invention relates to new compositions and methods for cleaning textile substrates, especially carpet and upholstery fabrics. More particularly, this invention relates to liquid compositions that contain absorbent particles in a flowable fluid dispersion, which dries to a soil ladened powder, that can be removed by vacuuming, brushing, and/or laundering methods. The composition includes dispersion stabilizing additives such that the composition is presented as a stable dispersion or as a composition that may be easily redispersed prior to application.

  • Publication number: 20080164439
    Abstract: The present disclosure is directed to synthetic textiles treated with h-PEI derivatives, such derivatives possessing the general structure shown below: (R)x?h-PEI?(A)y where R is a non-hyperbranched hydrocarbon group, said hydrocarbon group having at least one linear portion, said linear portion having between 5 and 30 carbon atoms; where x is a number from 1 to 10,000; where h-PEI is a hyperbranched polyethyleneimine; where A is an organic compound having from 1 to 4 carbon atoms; where y is a number from 0 to 500; and wherein R is present in an amount of between about 0.1% and about 80% by weight of the h-PEI derivative. The chemical treatment imparts durable odor control, softness, wrinkle resistance, and moisture wicking to substrates treated therewith.

  • Publication number: 20080163437
    Abstract: The present disclosure is directed to cellulosic textiles treated with h-PEI derivatives, such derivatives possessing the general structure shown below: (R)x?h-PEI?(A)y where R is a non-hyperbranched hydrocarbon group (for example, such as alkyl, alkenyl, arylalkyl, and arylalkenyl groups, where the number of carbon atoms in the linear portion of the hydrocarbon is between 5 and 30 carbon atoms), where x is a number from 1 to about 10,000 (depending on the Mn of the h-PEI), where h-PEI is a hyperbranched polyethyleneimine, where A is a small organic “capping” compound having from 1 to 4 carbon atoms, where y is a number from 0 to 10,000, and wherein R is present in an approximate amount of between about 20% and about 75% by weight of the h-PEI derviative. The chemical treatment imparts durable colorfastness, softness, wrinkle resistance, and reduced drying time to substrates treated therewith.

  • Publication number: 20030084514
    Abstract: Specific methods of dewrinkling fabrics (such as garments, tablecloths, and the like) through a spray-treatment with aqueous formulations of non-film producing fiber lubricants are provided. Such a method provides a relatively simple, yet highly effective manner of removing wrinkles from fabrics and also, since films are not produced on the surface of the target fabric substrate, of also permitting greater rewrinkling resistance to the treated fabric itself. A fabric treated in accordance with this method is also provided.

  • Patent number: 6461386
    Abstract: Specific transfer methods and articles to impart a metal-ion based antimicrobial finish to recipient textile surfaces. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. In particular, the inventive method involves the application of a solid, inorganic antimicrobial material to a donor substrate (such as a dryer sheet), and the subsequent placement of such a substrate within a tumble drying machine containing textile fabrics and operating the machine. The donor substrate, upon contact with the recipient textile fabrics, transfers antimicrobially effective amounts of the metal-ion based compounds to such recipient fabrics thereby imparting at least a temporary antimicrobial finish over at least a portion of such fabrics. The donor substrates, with either the antimicrobial compound alone or mixed with standard tumble dryer additives (such as perfumes, fabric softeners, fiber lubricants, and the like) are also contemplated within this invention.

  • Patent number: 5082896
    Abstract: A polymeric material is provided which comprises the following monomer units: from about 23 to about 32 parts by weight butyl acrylate; from about 16 to about 22 parts by weight of a lower alkyl methacrylate; from about 28 to about 40 parts by weight of a monomer selected from vinyl acetate and styrene; and from about 14 to about 20 parts by weight of an acidic monomer selected from acrylic acid and methacrylic acid; said polymer being further characterized as having an intrinsic viscosity of from about 0.16 to about 0.30 deciliter per gram as measured by a Cannon-Fenske Kinematic viscometer.

  • Patent number: 4415417
    Abstract: Photopolymerization of monomers by visible light using a photoreducible dye, a reducing agent and a controlled level of copper ions allows for high molecular weight polymer formation. The molecular weight is found to be proportional to the copper ion concentration. At 10 to 1,000 ppb copper ion concentration, the molecular weight of the polymer is optimum.
