  • Patent number: 10647783
    Abstract: The present disclosure provides methods for functionalizing the surfaces of cellulose nanoparticles. In embodiments, nanoparticles are aerosolized, and then passed through a flow reactor where they are contacted with gaseous reactants to functionalize the surface of the nanoparticles. In other embodiments, the nanoparticles are aerosolized, and then passed through a plasma reactor where they are contacted with gaseous reactants to functionalize the surface of the nanoparticles. Once the functionalized nanoparticles are produced, they may be combined with polymers to form polymer composites having both a polymer and the functionalized nanoparticles. Systems for producing these functionalized nanoparticles, coupled with downstream polymer processing equipment for forming the polymer composites, are also provided.

  • Patent number: 10428459
    Abstract: A pulp in accordance with a particular embodiment includes crosslinked cellulose fibers. The pulp can have high brightness, reactivity, and intrinsic viscosity. The pulp, therefore, can be well suited for use as a precursor in the production of low-color, high-viscosity cellulose derivatives. A method in accordance with a particular embodiment of the present technology includes forming a pulp from a cellulosic feedstock, bleaching the pulp, crosslinking cellulose fibers within the pulp while the pulp has a high consistency, and drying the pulp. The bleaching process can reduce a lignin content of the pulp to less than or equal to 0.09% by oven-dried weight of the crosslinked cellulose fibers. Crosslinking the cellulose fibers can include exposing the cellulose fibers to a glycidyl ether crosslinker having two or more glycidyl groups and a molecular weight per epoxide within a range from 140 to 175.

  • Patent number: 10167586
    Abstract: The present invention provides a production process characterized in that a false twisting process is added between a spinning process and a winding process so that yarn slivers undergo excessive pre-torsion in an axial direction and twists which are same in quantity but different in twisting direction are generated on the yarn slivers. Absorption of glucose-containing sulfur dyestuff is performed in a dyeing process. An ammonia removal process is performed in a high-temperature and high-pressure tank so that residual ammonia in a fabric is evaporated. The evaporated ammonia is collected and then fed back to a mercerizing process for continuous use. The present invention also provides a production line including a spinning unit having a false twisting device, a dyeing unit configured to realize the dyeing process, and a liquid ammonia finishing unit consisting of a fabric mercerizing device, an ammonia removal device, an ammonia recycling device and a controller.

  • Patent number: 8295970
    Abstract: Customers obtain customized textile materials by selecting style, shape, size, pattern and color for an undyed textile product. Based on a selection made by the customer, the textile product is transformed by a dyeing operation performed on a single item (or multiple items selected to be dyed the same) to yield a product, such as a shirt, pants, or jacket, which has a color and pattern of his or her own choosing, in the size and style he or she desires. The process can be performed in a retail setting using a dye apparatus which allows the process to be viewed by the customer. To enhance the educational and entertainment experience of the customer, the dyeing operation can be performed in a transparent tank or water kettle in the retail outlet so that the customer can view, for example, the garment as it is being dyed to the customer's specifications.

  • Patent number: 8277518
    Abstract: An ecological fabric having protection from ultraviolet radiation incorporated therein is disclosed in which the fabric is treated by a method comprising the steps of dissolving zinc acetate or other zinc salt in a liquid to form a solution containing Zn(II) ions, adding a fabric to the solution, mixing the solution and the fabric, and adding a base to the solution when the solution and the fabric are being mixed to form a suspension of zinc oxide nanoparticles in contact with the fabric. Other methods are disclosed such as modifying a fabric by carboxylation or phosphorylation of the fabric followed by binding of the UV-blocking nanoparticles to the modified fabric and modifying UV-blocking nanoparticles with a self-assembled monolayer (SAM) or polymer layer containing an active chemical group capable of binding to the fabric and depositing the UV-blocking nanoparticles on the fabric.

  • Patent number: 8163036
    Abstract: NM7O and NM3O coated clay are embedded into a fabric matrix to produce a protective fabric. A NM7O blended garment can be manufactured for the purpose of containing malodors. The destruction of chemical warfare agents can also be accomplished by incorporating these materials into disposable protective clothing for military, Haz-Mat team and First responders. The fabrics so treated with MN7O have uses as diverse as for a disposable silver polish wipe. In the case of NM3O coated clay, the treated fabric can be used as a copper and brass polish.

  • Patent number: 8043384
    Abstract: A method for making fire retardant material including fire retardant cellulosic insulation is described. The method includes an arrangement for adding one or more feedstocks and a fire retardancy chemical compound to a common blend tank prior to feedstock drying. The one or more feedstocks may include at least one virgin pulp stock feed and at least one recycled material stock feed. The amount and type of both the virgin feedstock and the recycled material feedstock is selectable. Old newsprint (ONP) may be one type of recycled material feedstock. Another suitable type of recycled material feedstock is old corrugated containers (OCC). The method further includes retaining the fiber feedstock and the chemical compound together for enough time to ensure adherence or impregnations of enough of the chemical to the fibers after the drying process. Fluffing or fiberizing of the treated fibers may be accomplished under less severe conditions than ordinarily employed when making conventional cellulose insulation.

  • Publication number: 20110183147
    Abstract: A method for functionalising a textile substrate made of a hydrophilic material in order to impart humidity transfer properties thereto, wherein the method includes the steps of: preparing a formulation of at least one hydrophobic material containing at least one group reacting under ionising radiation; forming a discontinuous layer using the formulation on a surface of the textile substrate; and applying an ionising radiation onto the discontinuous layer in order to graft the hydrophobic material on the surface of the substrate by the reaction of the reactive groups.

  • Publication number: 20110173763
    Abstract: The invention provides a process for aminoarylating cellulosic materials such as cotton and reconstituted fibres and a process for treating the aminoarylated cellulose with an effect chemical such as a dye, flame retardant or cross linking agent. Improved take up of the effect chemical by the modified cellulose means increased efficiency in the process and in the case of dyeing, avoids or reduces the washing off of hydrolysed dye and the resultant production of large volumes of contaminated water requiring to be treated. The cellulosic material may be present in a blend with other types of fibre for example a blend with poly(alkyleneterephthalates) or polyamides.
