Method for the manufacture of fibrous yarn

Abstract

Disclosed is a method for the manufacture of fibrous yarn including the steps, where an aqueous suspension including fibers and at least one rheology modifier is provided, followed by directing the suspension through at least one nozzle, to form at least one yarn, and then dewatering the yarn.

1 . A method for the manufacture of fibrous yarn, wherein said method comprises the steps, where an aqueous suspension comprising fibers and at least one rheology modifier is provided, followed by directing said suspension through at least one nozzle, to form at least one yarn, and then subjecting said yarn to dewatering. 
     
     
         2 . The method according to  claim 1 , wherein said method comprises the steps, where the nozzle has an inner diameter of the outlet smaller than or equal to the maximum length weighed fiber length of the fibers. 
     
     
         3 . The method according to  claim 1 , wherein said fibers originate from at least one plant based raw material source. 
     
     
         4 . The method according to  claim 1 , wherein said plant based raw material source is a virgin source or recycled source or any combination thereof. 
     
     
         5 . The method according to  claim 1 , wherein the suspension comprises virgin or recycled fibers originating from synthetic materials, or from natural materials, or combinations thereof. 
     
     
         6 . The method according to  claim 1 , wherein the rheology modifier is selected from alginic acid, alginates, pectin, carrageenan, and nanofibrillar cellulose and combinations thereof. 
     
     
         7 . The method according to  claim 1 , wherein the amount of the rheology modifier is from 0.1 to 20 weight %. 
     
     
         8 . The method according to  claim 1 , wherein the suspension comprises at least one dispersion agent, preferably an anionic long chain polymer or NFC or a combination thereof. 
     
     
         9 . The method according to  claim 1 , wherein the suspension comprises additives selected from surfactants, hydrophobicity agents, hydrophilicity agents, colorants, strength modifiers, elasticity modifiers, tensile strength modifiers, decorative pieces and metal powder. 
     
     
         10 . The method according to  claim 1 , wherein the suspension comprises alginates, pectin or carrageenan and at least one dispersion agent, and the yarn is treated with an aqueous solution comprising at least one cation prior to dewatering. 
     
     
         11 . The method according to  claim 1 , wherein the dewatering is carried out with at least one method based on vacuum, mechanical pressing and/or thermal drying. 
     
     
         12 . A fibrous yarn obtainable by the method of  claim 1 . 
     
     
         13 . A fibrous yarn comprising fibers originating from at least one plant based raw material source and at least one rheology modifier. 
     
     
         14 . Use of the fibrous yarn of  claim 12 , in the manufacture of textiles, decorative products, construction materials and composite materials. 
     
     
         15 . The method according to  claim 2 , wherein said fibers originate from at least one plant based raw material source. 
     
     
         16 . The method according to  claim 2 , wherein said plant based raw material source is a virgin source or recycled source or any combination thereof. 
     
     
         17 . The method according to  claim 3 , wherein said plant based raw material source is a virgin source or recycled source or any combination thereof. 
     
     
         18 . The method according to  claim 2 , wherein the suspension comprises virgin or recycled fibers originating from synthetic materials, or from natural materials, or combinations thereof. 
     
     
         19 . The method according to  claim 3 , wherein the suspension comprises virgin or recycled fibers originating from synthetic materials, or from natural materials, or combinations thereof. 
     
     
         20 . The method according to  claim 4 , wherein the suspension comprises virgin or recycled fibers originating from synthetic materials, or from natural materials, or combinations thereof.
