Knitted component with a surface area formed with high-tenacity yarn

Abstract

A knitted component may include a first surface and a second surface, the first surface facing opposite the second surface, the first surface including at least a first yarn and the second surface including at least a second yarn. The first and second yarns may be different. The first surface and the second surface may be secured via a knit structure of the knitted component, where the first surface includes an exposed first surface area, where at least 65% of the exposed first surface area is formed of the first yarn, and where the first yarn has a tenacity of at least 5 grams per denier (g/d).

We claim: 
     
         1 . A knitted component comprising:
 a first surface and a second surface, the first surface facing opposite the second surface, the first surface including at least a first yarn and the second surface including at least a second yarn, the first and second yarns being different,   wherein the first surface and the second surface are secured via a knit structure of the knitted component,   wherein the first surface includes an exposed first surface area,   wherein at least 65% of the exposed first surface area is formed of the first yarn, and   wherein the first yarn has a tenacity of at least 5 grams per denier (g/D).   
     
     
         2 . The knitted component of  claim 1 , wherein the first yarn has a tenacity of at least 7 grams per denier (g/D). 
     
     
         3 . The knitted component of  claim 1 , wherein the exposed first surface area has an area of at least 1 square centimeter. 
     
     
         4 . The knitted component of  claim 1 , wherein the exposed first surface area has an area of at least 9 square centimeters. 
     
     
         5 . The knitted component of  claim 1 , wherein at least 70% of the exposed first surface area is formed of the first yarn. 
     
     
         6 . The knitted component of  claim 1 , wherein the second yarn includes a tenacity of less than 4 grams per denier (g/D). 
     
     
         7 . The knitted component of  claim 1 , further comprising:
 a first zone; and   a second zone,   wherein the exposed first surface area is located in the first zone,   wherein in the second zone, the first surface includes an exposed second surface area, and   wherein the percentage of the exposed second surface area formed by the first yarn is different than the percentage of the exposed first surface area formed by the first yarn.   
     
     
         8 . The knitted component of  claim 7 , wherein less than 60% of the exposed second surface area is formed of the first yarn. 
     
     
         9 . The knitted component of  claim 1 , wherein the second surface includes an exposed second surface area, wherein at least 50% of the exposed second surface area is formed of the second yarn. 
     
     
         10 . The knitted component of  claim 1 , wherein the first yarn is a polyethylene terephthalate filament yarn. 
     
     
         11 . A method comprising:
 knitting a first layer of a knitted component; and   knitting a second layer of the knitted component,   wherein the first layer has a first surface and the second layer has a second surface, the first surface facing opposite the second surface, the first layer including at least a first yarn and the second layer including at least a second yarn, the first and second yarns being different,   wherein the first layer and the second layer are secured via a knit structure of the knitted component,   wherein the first surface includes an exposed first surface area,   wherein at least 65% of the exposed first surface area is formed of the first yarn, and   wherein the first yarn has a tenacity of at least 5 grams per denier (g/D).   
     
     
         12 . The method of  claim 11 , wherein the first yarn has a tenacity of at least 7 grams per denier (g/D). 
     
     
         13 . The method of  claim 11 , wherein the exposed first surface area has an area of at least 1 square centimeter. 
     
     
         14 . The method of  claim 11 , wherein the exposed first surface area has an area of at least 9 square centimeters. 
     
     
         15 . The method of  claim 11 , wherein at least 70% of the exposed first surface area is formed of the first yarn. 
     
     
         16 . The method of  claim 11 , wherein the second yarn includes a tenacity of less than 4 grams per denier (g/D). 
     
     
         17 . The method of  claim 11 , further comprising:
 knitting a first zone of the knitted component; and   knitting a second zone of the knitted component,   wherein the exposed first surface area is located in the first zone,   wherein in the second zone, the first layer includes an exposed second surface area, and   wherein the percentage of the exposed second surface area formed by the first yarn is different than the percentage of the exposed first surface area formed by the first yarn.   
     
     
         18 . The method of  claim 17 , wherein less than 60% of the exposed second surface area is formed of the first yarn. 
     
     
         19 . The method of  claim 18 , wherein the second surface includes an exposed second surface area, wherein at least 50% of the exposed second surface area is formed of the second yarn. 
     
     
         20 . The method of  claim 11 , wherein the first yarn is a polyethylene terephthalate filament yarn.
