Light woven sheet

Abstract

A woven sheet that is lightweight and breathable, while also being a durable, long-lasting type. The lightweight woven sheet comprises a dynamic grid construction that allows moisture vapor to escape while preserving durability of the sheet. The sheet includes a first section including a first type of weave having a first grid pattern and a second section including a second type of grid having a second grid pattern. The first weave is an open-weave, which makes the sheet breathable and lowers the overall weight of the sheet, while the second weave is a plain weave that provides durability to the overall sheet.

What is claimed is: 
     
         1 . A woven sheet comprising,
 a first section comprising a first weave having a first grid pattern; and   a second section comprising a second weave having a second grid pattern, the second section is coupled to the first section;   wherein an area of first section is greater than an area of the second section;   wherein the first grid pattern is less dense than the second grid pattern;   wherein the first weave contributes most to an air permeability characteristic of the woven sheet; and   wherein the second weave contributes most to a durability characteristic of the woven sheet.   
     
     
         2 . The woven sheet of  claim 1 , wherein the second weave is a plain weave. 
     
     
         3 . The woven sheet of  claim 2 , wherein the second grid pattern is a 1-by-1 grid pattern. 
     
     
         4 . The woven sheet of  claim 1 , wherein the first weave is a dobby weave. 
     
     
         5 . The woven sheet of  claim 4 , wherein the first pattern is a 2-by-2 grid pattern. 
     
     
         6 . The woven sheet of  claim 1 , wherein the air permeability characteristic of the first section is about 304 cubic feet per minute or greater. 
     
     
         7 . The woven sheet of  claim 1 , wherein a weight characteristic of the woven sheet is about 85 grams per square meter or less. 
     
     
         8 . The woven sheet of  claim 1 , wherein the first section comprises a first geometric pattern and a second geometric pattern. 
     
     
         9 . The woven sheet of  claim 1 , wherein the first section and the second section are directly connected. 
     
     
         10 . The woven sheet of  claim 1 , wherein the first section and the second section comprise a lyocell fiber. 
     
     
         11 . A woven sheet comprising:
 a first section having a 2-by-2 dobby weave; and   a second section having a 1-by-1 plain weave, the first section contacting the second section,   wherein an area of first section is greater than an area of the second section; and   wherein the first section and the second section both comprise a lyocell fiber.   
     
     
         12 . A method of making a woven sheet, the method comprising the steps of:
 weaving a first section using a first weave having a first grid pattern; and   weaving a second section using a second weave having a second grid pattern, the second section coupled to the first section;   wherein an area of first section is greater than an area of the second section;   wherein the first grid pattern is less dense than the second grid pattern;   wherein the first weave contributes most to an air permeability characteristic of the woven sheet; and   wherein the second weave contributes most to a durability characteristic of the woven sheet.   
     
     
         13 . The method of  claim 12 , wherein the second weave is a plain weave. 
     
     
         14 . The method of  claim 13 , wherein the second grid pattern is a 1-by-1 grid pattern. 
     
     
         15 . The method of  claim 12 , wherein the first weave is a dobby weave. 
     
     
         16 . The method of  claim 15 , wherein the first pattern is a 2-by-2 grid pattern. 
     
     
         17 . The method of  claim 12 , wherein the air permeability characteristic is equal or greater than about 304 cubic feet per minute. 
     
     
         18 . The method of  claim 12 , wherein a weight characteristic of the woven sheet is equal or less than about 85 grams per square meter. 
     
     
         19 . The method of  claim 12 , wherein the first section comprises a first geometric pattern and a second geometric pattern. 
     
     
         20 . The method of  claim 12 , wherein the first section and the second section are connected directly. 
     
     
         21 . The method of  claim 12 , wherein the first section and the second section comprise a lyocell fiber.
