  • Patent number: 9970159
    Abstract: A hydrated, nonwoven nanocellulose sheet and method for manufacturing the nanocellulose sheet are disclosed. The method of manufacture comprises the steps of diluting a purified nanocellulose slurry to form a colloidal nanocellulose suspension, dispersing pure nanocellulose crystals into the nanocellulose suspension in a nanocellulose crystal to total nanocellulose ratio less than 50% weight per weight (w/w), placing the suspension over a filter sheet in a dispensing device, and forming the hydrated, nonwoven nanocellulose sheet by filtering with a pressure difference across the filter sheet, via a high pressure or vacuum filtration process. The hydrated, nonwoven nanocellulose sheet thus manufactured has high conformability, drape-ability, good adhesion to the skin, and a high rate of evaporation, making it ideal for dermatological treatments.

  • Patent number: 9321909
    Abstract: Provided are a rubber composition for tire containing raw material rubber and cellulose whiskers, and a tire produced from the same composition and having excellent general properties. Since the rubber composition for tire contains cellulose whiskers having superior reinforcing properties than rubber reinforcing materials, the rubber composition for tire can provide a tire having markedly enhanced properties compared to tires using the conventional rubber reinforcing materials. Also, when cellulose whiskers are applied to the rubber composition for tire, the content of the conventional rubber reinforcing materials can be reduced. As a result, the elongation ratio and low-fuel consumption performance that have been considered poor due to the use of conventional rubber reinforcing materials can be improved to a superior level, and a lightweight tire can be provided.

    Abstract: The invention relates to a process for producing cellulosic shaped articles with stabilized inclusions in a microfine dispersion of nonpolar organic compounds and mixtures by a dry-wet extrusion process. The shaped articles produced in this way exhibit by comparison with unmodified cellulose fibers a substantially increased storage capacity for heat and/or nonpolar active substances. They are suitable in particular for use in textiles for clothing, industrial textiles, leisure, medicine and cosmetics. Potential functional effects imparted include the physical effect of heat storage and/or the uniform and finely meterable storage and release of nonpolar active substances and plant extracts from the interior of the fibers of the shaped articles. It is possible through a suitable choice of the nonpolar portion to produce by this process also fibers capable of absorbing liquid or gaseous nonpolar substances.

  • Patent number: 8652636
    Abstract: Dried nanocrystalline cellulose (NCC), in particular films of NCC, of controlled water dispersibility and a method to control the dispersibility of dried NCC by controlling electrolyte solution ionic strength and ion valency is described. Neutral M-NCC suspensions containing monovalent counterions (e.g., M=Na+, K+, NH4+, Et4N+) produced by neutralization of acid-form NCC (H-NCC) with the appropriate hydroxide, are readily dispersible in water when fully dried; this is in contrast to H-NCC. The dispersion of dried M-NCC in aqueous media is effectively prevented by a combination of (1) increased electrolyte concentration and ionic strength, and (2) higher valency of the cation component of the dissolved salt. Additionally, pre-treatment of dried M-NCC films with an electrolyte solution having a polyvalent cation, for example a divalent or trivalent cation is sufficient to prevent the subsequent dispersion of the M-NCC film in pure water.

  • Patent number: 8568892
    Abstract: A coated article includes a substrate having on its surface a coating that includes a polymer selected from the group consisting of hydroxypropylcellulose, poly(2-ethyl-2-oxazoline) and mixtures of these, a surfactant, colloidal silica, and a crosslinker selected from the group consisting of water-soluble titanium salts and water-soluble or water-dispersible organic crosslinkers. The coating may be formed by applying a dispersion of the coating composition in a diluent to the substrate and subsequently drying the coated substrate to evaporate the diluent.

  • Publication number: 20130160674
    Abstract: A method of forming an asphalt mixture can include mixing a bio-asphalt and a bitumen source material different from the bio-asphalt. The bio-asphalt can be formed by mixing a bio-source material with a liquid catalyst. Particles can be added to the asphalt mixture. In an embodiment, the bitumen source material can have a softening point of at least approximately 93° C. and a penetration distance no greater than approximately 25 dmm. In another embodiment, the roofing-grade asphalt mixture can have a softening point of at least approximately 104° C., a penetration distance no greater than approximately 12 dmm, a viscosity of at least approximately 3000 cps at a temperature of 204° C., or any combination thereof. The asphalt mixture can be applied to a base material to form a roofing product. The asphalt mixture can be applied as a pavement product.
