A method of forming a colored heather yarn, comprising the sequential steps: (a) processing a natural fiber; (b) obtaining a regenerated cellulose man-made fiber; (c) producing a waterless dope-dyed man-made fiber; (d) blending the individual fibers from steps (a)-(c) to produce a blended composite of fibers; and (e) roving, spinning and winding the blended composite of fibers of step (d) into a final colored heather yarn; wherein the colored heather yarn comprises a predetermined fiber content ratio. There is also provided a colored heather yarn made according to the foregoing method.

A method and system for the production of fibers for use in biocomposites is provided that includes the ability to use both retted and unretted straw, that keeps the molecular structure of the fibers intact by subjecting the fibers to minimal stress, that maximizes the fiber's aspect ratio, that maximizes the strength of the fibers, and that minimizes time and energy inputs, along with maintaining the fibers in good condition for bonding to the polymer(s) used with the fibers to form the biocomposite material. This consequently increases the functionality of the biocomposites produced (i.e. reinforcement, sound absorption, light weight, heat capacity, etc.), increasing their marketability. Additionally, as the disclosed method does not damage the fibers, oilseed flax straw, as well as all types of fibrous materials (i.e. fiber flax, banana, jute, industrial hemp, sisal, coir) etc., can be processed in bio composite materials.

Methods for spinning, weaving, and finishing fabric and/or cloth containing cotton fibers are disclosed. The methods of the invention are performed at lower ambient, solution and/or working temperatures than is previously known in the art. The reduced temperature processing improves various qualities of the resulting textile products and fabrics and lowers costs of operating the processing facility.

The present invention is directed to plant fiber-reinforced biocomposite thermoplastic and/or resin compositions and a method for reinforcing thermoplastic resins. The present invention provides a use for the cellulose portion of a plant material, which is the portion left over after processing the selected plant materials to separate the cellulose in a mechanical process that does not damage the internal molecular structure of the cellulose fraction, enabling the cellulose fraction to chemically bond with the thermoplastic resin to enhance the reinforcement of the resin or thermoplastic biocomposite composition.
