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.

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.
