Blanket and method of manufacture thereof

Abstract

An example blanket includes: a yarn having a predefined length based on a target size of the blanket, wherein the yarn is interlaced to form the blanket, the yarn comprising: an outer layer comprising a first layer of fabric forming a tube, the outer layer having the predefined length and defining a fixed diameter of the tube and a fixed interior capacity of the tube based on the fixed diameter; and an inner layer comprising a second layer of fabric, having the predefined length and a width selected based on a target pressure to be applied over the target size of the blanket, wherein the inner layer is disposed in the tube to fill a portion of the fixed interior capacity of the tube.

1 . A blanket comprising:
 a yarn having a predefined length based on a target size of the blanket, wherein the yarn is interlaced to form the blanket, the yarn comprising:
 an outer layer comprising a first layer of fabric forming a tube, the outer layer having the predefined length and defining a fixed diameter of the tube and a fixed interior capacity of the tube based on the fixed diameter; and 
 an inner layer comprising a second layer of fabric, having the predefined length and a width selected based on a target pressure to be applied over the target size of the blanket, wherein the inner layer is disposed in the tube to fill a portion of the fixed interior capacity of the tube. 
   
     
     
         2 . The blanket of  claim 1 , wherein the inner layer comprises a single fabric sheet. 
     
     
         3 . The blanket of  claim 1 , wherein the inner layer fills less than a maximum of the fixed interior capacity of the tube. 
     
     
         4 . The blanket of  claim 1 , wherein a ratio of the width of the inner layer to a perimeter of the tube is greater than about 1. 
     
     
         5 . The blanket of  claim 1 , wherein a ratio of the width of the inner layer to a perimeter of the tube is greater than about 0.75. 
     
     
         6 . The blanket of  claim 1 , wherein the inner layer further has a weight selected to optimize a ratio of the width of the inner layer to a perimeter of the tube. 
     
     
         7 . The blanket of  claim 1 , wherein the width of the inner layer is selected to achieve a target weight for the blanket. 
     
     
         8 . The blanket of  claim 1 , wherein the inner layer is rolled along the predefined length. 
     
     
         9 . A method of manufacturing a blanket, the method comprising:
 selecting a target size of the blanket and predefining a length of yarn to be interlaced to form the blanket based on the target size;   providing an outer layer having the predefined length and forming a tube to define an interior capacity;   selecting a width for an inner layer based on a target pressure to be applied over the target size of the blanket;   providing the inner layer having the predefined length and the selected width;   inserting the inner layer into the outer layer to fill at least a portion of the interior capacity, wherein the outer layer filled with the inner layer defines the yarn; and   interlacing the yarn to form the blanket.   
     
     
         10 . The method of  claim 9 , wherein the inner layer comprises a single fabric sheet. 
     
     
         11 . The method of  claim 9 , wherein the inner layer fills less than a maximum of the interior capacity of the tube. 
     
     
         12 . The method of  claim 9 , wherein a ratio of the width of the inner layer to a perimeter of the tube is greater than about 1. 
     
     
         13 . The method of  claim 9 , wherein a ratio of the width of the inner layer to a perimeter of the tube is greater than about 0.75. 
     
     
         14 . The method of  claim 9 , wherein the inner layer further has a weight selected to optimize a ratio of the width of the inner layer to a perimeter of the tube. 
     
     
         15 . The method of  claim 9 , wherein the width of the inner layer is selected to achieve a target weight for the blanket. 
     
     
         16 . The method of  claim 9 , wherein the inner layer is rolled along the predefined length.
