Abstract

Temperature-regulating fabrics composed of natural fibers that are wearable in all seasons and provide high-performance thermal regulation and excellent wicking and absorbency properties. The temperature-regulating natural fabrics disclosed herein are composed of a blend of cotton, hemp, and linen present in an amount of between 84% and 100% of the total composition. In some embodiments, the temperature-regulating natural fabric displays a high amount of stretch and a low amount of growth.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A temperature-regulating natural fabric, comprising:
 natural fibers, the natural fibers being at least 84% of a total composition, wherein the natural fibers include all of cotton, hemp, and linen.   
     
     
         2 . The temperature-regulating natural fabric of  claim 1 , wherein cotton is at least 55% of the total composition. 
     
     
         3 . The temperature-regulating natural fabric of  claim 1 , wherein hemp is at least 14% of the total composition. 
     
     
         4 . The temperature-regulating natural fabric of  claim 1 , wherein linen is at least 5% of the total composition. 
     
     
         5 . The temperature-regulating natural fabric of  claim 1 , further comprising at least one synthetic fiber. 
     
     
         6 . The temperature-regulating natural fabric of  claim 5 , wherein the synthetic fiber is polyester. 
     
     
         7 . The temperature-regulating natural fabric of  claim 5 , wherein the synthetic fiber is an elastic fiber. 
     
     
         8 . The temperature-regulating natural fabric of  claim 5 , wherein the synthetic fiber is at least 6% of the total composition. 
     
     
         9 . The temperature-regulating natural fabric of  claim 1 , wherein the temperature-regulating natural fabric has a tear strength in the warp direction of at least 6400 g. 
     
     
         10 . The temperature-regulating natural fabric of  claim 1 , wherein the temperature-regulating natural fabric has a tear strength in the weft direction of at least 4900 g. 
     
     
         11 . The temperature-regulating natural fabric of  claim 1 , wherein the temperature-regulating natural fabric has a tensile strength in the warp direction of at least 68 kg. 
     
     
         12 . The temperature-regulating natural fabric of  claim 1 , wherein the temperature-regulating natural fabric has a tensile strength in the weft direction of at least 32.9 kg. 
     
     
         13 . The temperature-regulating natural fabric of  claim 1 , wherein the temperature-regulating natural fabric has a stretch percentage of at least 36.6%. 
     
     
         14 . The temperature-regulating natural fabric of  claim 1 , wherein the temperature-regulating natural fabric has a growth percentage of at most 8.36%. 
     
     
         15 . The temperature-regulating natural fabric of  claim 1 , wherein the temperature-regulating natural fabric has an absorbency value of 1 second. 
     
     
         16 . The temperature-regulating natural fabric of  claim 1 , wherein the temperature-regulating natural fabric has a wicking value in the warp direction of at least 3.5 inches per 30 minutes. 
     
     
         17 . The temperature-regulating natural fabric of  claim 1 , wherein the temperature-regulating natural fabric has a wicking value in the weft direction of at least 3.5 inches per 30 minutes. 
     
     
         18 . The temperature-regulating natural fabric of  claim 1 , wherein the temperature-regulating natural fabric has a CLO value of at least 0.2. 
     
     
         19 . A temperature-regulating natural fabric, comprising:
 cotton being at least 55% of the total composition;   hemp being at least 14% of the total composition; and   linen being at least 9% of the total composition.   
     
     
         20 . The temperature-regulating fabric of  claim 19 , wherein cotton is approximately 57% of the total composition, hemp is approximately 19% of the total composition, and linen is approximately 11% of the total composition, the temperature-regulating fabric further comprising:
 approximately 11% polyester; and   approximately 2% spandex.
