A method for producing a reinforced textile fiber composition comprising
- a) providing a textile fiber composition
- b) optionally forming a textile from the textile fiber composition, and
- c) subjecting the textile fiber composition to covalent crosslinking of the textile fibers thereby reinforcing the textile.
The method of any preceding claim, wherein the textile fibers comprise natural or biological plant derived fibers optionally derived from cotton, kapok, hemp (Cannabis sativa or Apocynum cannabinum or Furcraea foetida), flax (Linum usitatissimum), jute (Corchorus species including C. olitorius and C. capsularis), ramie (Boehmeria nivea), kenaf (Hibiscus cannabinus), roselle (Hibiscus sabdariffa), sunn (Crotalaria juncea), urena (Urena lobata), nettle, manila, abaca (Musa textilis), cantala (Agave cantala), henequen (Agave fourcroydes), maguey (Agave americana and other species), phormium (Phormium tenax), sisal (Agave sisalana), akund floss (Calotropis procera and C. gigantea), bagasse (Saccharum officinarum), bamboo (various species), bombax cotton (bombax species), coir (Cocos nucifera) and or wood.
The method of any preceding claim, wherein the textile fibers have an average length of between 0.01 mm to 1000 mm, optionally less than 1 mm.
The method of any preceding claim, wherein the textile fibers are spun fibers
The method of any preceding claim, wherein the reinforced textile is a woven, knitted, braided, crocheted, felted or non-woven fabric.
The method of any preceding claim, wherein the reinforced textile comprises less than 5% wt of binders, activators, adhesives/glues added to the textile.
The method of any preceding claim, wherein the reinforced textile is a fabric or cloth.
The method of any preceding claim, wherein the covalent cross-linking of textile fibers in the textile fiber composition comprises subjecting the textile fibers to one or more cross-linking catalysts and/or to one or more reactive additives (mediators) or any combination thereof.
The method of any preceding claim, wherein the covalent cross-linking of textile fibers further comprises subjecting the textile fibers to one or more water soluble reactive textile components (mediators).
The method of any preceding claim, wherein the covalent cross-linking of textile fibers further comprises subjecting the textile fibers to photo oxidation.
The method of any preceding claim, further comprising a step of adding a cofactor or activating agent for the catalyst.
The method of any preceding claim, further comprising a mechanical treatment of the textile fiber composition providing increased penetration of a liquid comprising a catalyst and/or mediator into the textile fiber composition thereby promoting the covalent crosslinking of fibers by the catalyst/mediator compared to a method without the mechanical treatment of the textile fiber composition.
The method of any preceding claim, further comprising physical entanglement of the textile fibers in the textile composition, wherein the physical entanglement comprises subjecting the textile fibers to one or more air and/or water jets (Hydro-entanglement) and/or needle-punch devices intercalating the fibers.
The method of any preceding claim further comprising a step of adding one or more benefit agents for coloring, printing, or coating of the textile fibers or reinforced textile.
The method of any preceding claim further comprising one or more steps of prior to the covalent crosslinking selected from
- a) Colleting materials containing the textile fibers, optionally waste materials;
- b) Transporting the collected material to a processing facility for processing the materials;
- c) Shredding the material containing the textile fibers;
- d) Washing the shredded material of step a);
- and/or
- e) Refining the shredded and/washed material by removing one or more residues selected from lignin, colors, wax or protein.
A reinforced textile obtainable from the method of any preceding claim.
