Sock

Abstract

A knitted sock has an inner layer 2 comprising a toe end 4 and an outer layer 3 comprising a toe end 7 . The inner and outer toe ends are aligned and joined wale stitch to wale stitch to form a composite toe end, which is closed to provide a flat toe seam 10 . The layered sock is manufactured complete in a single process being knit continuously from the inner toe end to the outer toe end. It comprises reciprocated heel and toe portions. The foot portion of the inner layer is knit from a yarn with properties such as a low coefficient of friction and/or antifungal/antibacterial properties. The low friction fiber is a fluoropolymer such as polytetrafluroethylene. The outer layer may comprise a cushion structure.

1 . A knitted sock comprising:—
 an inner sock layer; and    an outer sock layer,    the inner sock layer having a foot portion that is knit from a composite yarn comprising a first fiber having a low coefficient of friction and a second fiber having a higher coefficient of friction that the first fiber.

         5 . A sock as claimed in  claim 1  wherein the second fiber is a polyproplylene fiber.  
     
     
         6 . A sock as claimed in  claim 1  wherein the second fiber is a polyamide fiber.  
     
     
         7 . A sock as claimed in  claim 1  wherein the foot portion of the inner layer comprises a heel portion, a toe portion and a sole portion and the heel portion, toe portion and sole portion are knit from the same composite yarn.  
     
     
         8 . A sock as claimed in  claim 7  wherein the inner sock layer comprises a reciprocated heel portion.  
     
     
         9 . A sock as claimed in  claim 1  wherein the inner sock layer comprises a leg portion of unrestrictive construction.  
     
     
         10 . A sock as claimed in  claim 9  wherein the leg portion of the inner sock layer is of a different fiber to that of the foot portion.  
     
     
         11 . A sock as claimed in  claim 10  wherein the leg portion of the inner sock layer is of a polyamide fiber.  
     
     
         12 . A sock as claimed in  claim 10  wherein the leg portion of the inner sock layer is of a Nylon fiber.  
     
     
         13 . A sock as claimed in  claim 1  wherein the outer sock layer comprises a foot portion.  
     
     
         14 . A sock as claimed in  claim 1  wherein the outer sock layer comprises a heel portion, a toe portion and a sole portion.  
     
     
         15 . A sock as claimed in  claim 14  wherein the outer sock layer comprises a reciprocated heel portion.  
     
     
         16 . A sock as claimed in  claim 13  wherein the foot portion of the outer layer is of a cushion structure.  
     
     
         17 . A sock as claimed in  claim 13  wherein the foot portion of the outer sock layer is of terry structure.  
     
     
         18 . A sock as claimed in  claim 13  wherein the foot portion of the outer layer is of a hydrophilic material.  
     
     
         19 . A sock as claimed in  claim 1  wherein the outer layer comprises a leg portion.  
     
     
         20 . A sock as claimed in  claim 19  wherein the leg portion of the outer layer is of relaxed construction.  
     
     
         21 . A sock as claimed in  claim 19  wherein the leg portion of the outer layer is of restrictive construction.  
     
     
         22 . A sock as claimed in  claim 1  wherein at least a portion of the outer layer incorporates at least one technical yarn.  
     
     
         23 . A sock as claimed in  claim 22  wherein a technical yarn is a fiber having antifungal and/or antibacterial properties.  
     
     
         24 . A sock as claimed in  claim 23  wherein the fiber is a coated Nylon.  
     
     
         25 . A sock as claimed in  claim 24  wherein the fiber is a silver coated Nylon.
