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.

The invention discloses a technology for recovery, regeneration and reuse of soluble textiles. The technology comprises the steps of: the dissolution-controlled soluble polyester fibres are processed into soluble apparel accessories through conventional weaving, dyeing, finishing and tailoring or injection molding; the apparels or the soluble apparel accessories are dissolved under a certain condition, on one hand, the dissolving solution is filtered and solutes are recovered to obtain a high purity of terephthalic acid and ethylene glycol, which are reused to the polymerization of the soluble polyester, and the slices of the soluble polyester are obtained to be re-spun into the soluble fibres for reuse; on the other hand, the incompact and undissolved textiles are treated into an incompact fibre aggregation with good qualities by processes including disinfection, decolourization or redyeing, which are processed into high-quality textile fibres for reuse after drying or softly carding.
