Abstract

A hygienic footwear cushion having a composition comprising bamboo charcoal soot and a footwear material and a method of manufacturing such footwear cushion are disclosed. The footwear cushion material is SEBE, other SEBE equivalent material, or other suitable material for manufacturing footwear cushion. The hygienic footwear cushion according to the current invention provides an improved ability to maintain dryness and obtains the property to be bacteria and odor free.

1 . A hygienic footwear cushion having a composition, the composition comprising:
 bamboo charcoal soot;   a footwear cushion material; and   wherein said footwear cushion material is at least one selected from the group consisting of poly-styrene-ethylene-butylene-styrene (SEBE), SIS, ISI, SBS, TPE, TPR, and PU.   
     
     
         2 . The hygienic footwear cushion of  claim 1 , wherein said bamboo charcoal soot and said footwear cushion material has a ratio including and between 1:1000 by weight and 10:1000 by weight. 
     
     
         3 . The hygienic footwear cushion of  claim 2 , wherein said bamboo charcoal soot and said footwear cushion material having a ratio including and between 3:1000 by weight and 7:1000 by weight. 
     
     
         4 . They hygienic footwear cushion of  claim 1 , wherein said hygienic footwear cushion occupies a frontal area of a shoe designated for a ball area and a toe area of a foot. 
     
     
         5 . The hygienic footwear cushion of  claim 1 , wherein said footwear cushion material having a plurality of indentations designated on a front portion of said footwear cushion and a plurality of protrusions designated on a back portion of said footwear cushion. 
     
     
         6 . The hygienic footwear cushion of  claim 5 , wherein each of said plurality of indentations has an elliptical shape and wherein each of said plurality of protrusions has an inverted-Y shape. 
     
     
         7 . A method of making a hygienic footwear cushion, the method comprising:
 placing a footwear cushion material and bamboo charcoal soot into a container to create a mixture;   placing said mixture into an injection machine;   setting a temperature including and between 150 degree Celsius and 200 degree Celsius;   setting a pressure including and between 50 kilograms per square centimeter and 100 kilograms per square centimeter; and   setting injection time including and between 25 seconds and 50 seconds.   
     
     
         8 . The method of  claim 7 , wherein said bamboo charcoal soot and said footwear cushion material has a ratio including and between 1:1000 by weight and 10:1000 by weight. 
     
     
         9 . The method of  claim 7 , wherein said bamboo charcoal soot and said footwear cushion material having a ratio including and between 3:1000 by weight and 7:1000 by weight. 
     
     
         10 . The method of  claim 7 , wherein said temperature is including and between 170 degree Celsius and 190 degree Celsius. 
     
     
         11 . The method of  claim 7 , wherein said pressure is including and between 60 kilograms per square centimeter and 85 kilograms per square centimeter. 
     
     
         12 . The method of  claim 7 , wherein said injection time is including and between 35 seconds and 45 seconds.
