    摘要: Disclosed are various embodiments for dyeing a material using a dyed nanocellulose dispersion, thereby reducing or eliminating the need for water in dyeing materials, such as fabrics and textiles. A dyed nanocellulose dispersion or gel may be prepared from wood pulp fibers using a homogenizer and a dye, wherein the dyed nanocellulose dispersion comprises nanosized cellulose fibrils. The dyed nanocellulose gel may comprise an approximate concentration of 0.5% to 6%. The dyed nanocellulose dispersion may be applied to a material, such as a fabric or textile material. The fabric or textile material can be dried resulting in a dyed material.

    摘要: Provided are methods for forming single filament nanofibers, methods for forming 3D nanofiber scaffolds, apparatus for forming nanofibers and nanofiber scaffolds, and nanofiber cell culture scaffolds formed using the methods and devices. Single filament nanofibers (having a diameter of about 50 nm-100 μm) can be formed by gravitational drawing by dispensing a droplet of a polymer solution from a nozzle such that the droplet free falls from the nozzle onto a base, causing the polymer solution to be drawn into a fluid tail. Nanofiber scaffolds can be built by forming and collecting single filament nanofibers in an ordered manner on a collection frame to form 2D arrays that can then be stacked. The spacing and alignment of individual fibers is precisely controlled. Device for forming the 3D nanofiber scaffolds are provided. The 3D nanofiber scaffolds can be cell culture scaffolds having a porosity of 50% or greater.

    摘要: Nanofiber spinning apparatuses and methods for making core-sheath materials using touch spinning are provided. The apparatus includes at least one rotating plate with an aperture through which a core yarn passes and at least one post contacting the rotating plate. A speed control device can be configured to control rotation of the rotating plate, and a dispensing device can be configured to dispense a nanofiber-forming material onto the post. To make a core-sheath yarn a core yarn is passed through an aperture in a rotating plate having at least one post. The post is contacted with a nanofiber-forming material the rotating plate is rotated to draw a fiber of nanofiber-forming material from the post to wrap the fiber around the core yarn.

    摘要: A simple controllable set-up for drawing single filament nanofibers from polymer solutions or melts using a rotating rod or a set of rods (round brush) is described. The set-up can be assembled in a few minutes and applied to fabricate customized nanofiber scaffolds and meshes for various applications. The resulting fiber diameter is controlled precisely in the range 40 nm to 5 μm by adjusting the rotational speed and polymer concentration. Owing to the simple design and capability to manipulate single nanofibers, the spinning set-up can be used to wind a single filament into unidirectional, orthogonal or randomly oriented 2D and 3D meshes with controlled density, thickness and combinations of different fibers and materials in the scaffolds. The method is scalable and can be implemented easily for laboratory and industrial manufacturing.
