Composite Thread and Obtained Textile

Abstract

The invention relates to a composite thread ( 18 ), comprising a core ( 16 ) and a shell ( 17 ). The core ( 16 ) is produced from at least one thread of one or more metallic materials with biocidal properties. The shell ( 17 ) is made from one or more textile fibres directly covering all or part of the core ( 16 ).

1 . A composite yarn, comprising a core ( 16 ) and a sheath ( 17 ,  19 ), characterized in that the core ( 16 ) is made from at least one yarn of one or more metallic materials with biocidal properties and in that the sheath ( 17 ,  19 ) is made from one or more textile fibers directly covering all or part of the core ( 16 ). 
     
     
         2 . The yarn as claimed in  claim 1 , characterized in that the yarn(s) of the core ( 17 ) is (are) made with one or more metallic materials with biocidal properties. 
     
     
         3 . The yarn as claimed in  claim 1 , characterized in that the core ( 16 ) can have an apparent surface with a structure which forms points of attachment for the textile fiber(s) of the sheath ( 17 ,  19 ). 
     
     
         4 . The yarn as claimed in  claim 1 , characterized in that the metallic material(s) with biocidal properties is (are) chosen, alone or as an alloy, from the group comprising zinc, silver, tin, copper, gold and nickel. 
     
     
         5 . The yarn as claimed in  claim 1 , characterized in that the textile fiber(s) of the sheath ( 17 ,  19 ) is (are) chosen, alone or as a mixture, from the group comprising fibers of natural origin, preferably cotton, wool, silk, flax or cellulose, artificial fibers and synthetic fibers, preferably acrylics, polyamides or polypropylenes. 
     
     
         6 . The yarn as claimed in  claim 1 , characterized in that the sheath ( 17 ,  19 ) is produced by a process of mechanical textile binding, spinning, throwing, wrapping, lapping, twisting or Dref™ friction spinning. 
     
     
         7 . The yarn as claimed in  claim 1 , characterized in that all or part of the core is covered with a porous coating so as to facilitate the attachment of the textile fiber(s) of the sheath. 
     
     
         8 . A textile, characterized in that it comprises at least one composite yarn ( 18 ,  21 ) according to  claim 1 . 
     
     
         9 . The textile as claimed in  claim 8 , characterized in that it is produced by a weaving, knitting, braiding, embroidery, napping or nonwoven process. 
     
     
         10 . An article of clothing, characterized in that it is assembled using at least one composite yarn ( 18 ,  21 ) as claimed in  claim 1 . 
     
     
         11 . The yarn as claimed in  claim 2 , characterized in that the core ( 16 ) can have an apparent surface with a structure which forms points of attachment for the textile fiber(s) of the sheath ( 17 ,  19 ).
