Eco-friendly crochet style synthetic braiding hair and its manufacturing method

Abstract

An eco-friendly crochet style synthetic braiding hair and its manufacturing method are disclosed. The synthetic braiding hair is comprised of a plurality of the first synthetic fibers configured to easily form a curly shape; a plurality of the second synthetic fibers configured to be half-length of the plurality of the first synthetic fibers and have a high elastic recovery to maintain curly shape; and a plurality of the combined synthetic fibers is made by plurality of the second synthetic fibers being combined in the middle of the plurality of the first synthetic fibers and folded together.

We claim: 
     
         1 . An eco-friendly crochet style synthetic braiding hair comprising:
 a plurality of the first synthetic fibers configured to easily form curly shape;   a plurality of the second synthetic fibers configured to have high elastic recovery to maintain curly shape therein; and   wherein a plurality of the combined synthetic fibers is formed by the plurality of the second synthetic fibers being placed in the middle of the plurality of the first synthetic fibers and folded together.   
     
     
         2 . The synthetic braiding hair of  claim 1 ,
 wherein the plurality of the first synthetic fibers and the plurality of the second synthetic fibers are pre-treated to create unevenness and irregularity on surfaces thereof to resemble natural human hair.   
     
     
         3 . The synthetic braiding hair of  claim 1 ,
 wherein the plurality of the first synthetic fibers is capable of hot water setting to form curly hair.   
     
     
         4 . The synthetic braiding hair of  claim 1 ,
 wherein the plurality of the second synthetic fibers is capable of maintaining curly shape of the plurality of the combined synthetic fibers by material characteristics of high elastic recovery thereof.   
     
     
         5 . The synthetic braiding hair of  claim 1 ,
 wherein the plurality of the second synthetic fibers is capable of hot water setting to form curly hair and its weight is lighter and more volumetric than the plurality of the first synthetic fiber.   
     
     
         6 . The synthetic braiding hair of  claim 3 ,
 wherein the plurality of the first synthetic fibers is made by Polypropylene (PP) compound to be configured of hot water setting for curly shape.   
     
     
         7 . The synthetic braiding hair of  claim 4 ,
 wherein the plurality of the second synthetic fibers is made by a mixture of Poly-Ethylene Terephthalate (PET) compound and Poly-Butylene Terephthalate (PBT) to create high elastic recovery of curly shape.   
     
     
         8 . The synthetic braiding hair of  claim 7 ,
 wherein the mixing ratio of PET and PBT is one to one.   
     
     
         9 . The synthetic braiding hair of  claim 1 ,
 wherein the plurality of the combined synthetic fibers is pre-separated into a separated plurality of the combined synthetic fibers so that it is attached directly onto human hair.   
     
     
         10 . The synthetic braiding hair of  claim 9 , is further comprised of
 a loop attached in the middle of the separated plurality of the combined synthetic fibers and configured to easily install the separated plurality of the combined synthetic fibers onto human hair.   
     
     
         11 . A method of a manufacturing an eco-friendly crochet style synthetic braiding hair comprising the steps of:
 corrugating a fiber bundle;   stretching a plurality of the first synthetic fibers;   stretching a plurality of the second synthetic fibers;   creating a plurality of the combined synthetic fibers;   forming curly shape to the plurality of the combined synthetic fibers;   dividing into to a separated plurality of the combined synthetic fibers; and,   attaching a loop in the middle of the separated plurality of the combined synthetic fibers.   
     
     
         12 . The method of manufacturing the synthetic braiding hair in  claim 11  in which the step of corrugating the fiber bundle uses a conveyer belt unit with a plurality of corrugated heated rollers to create unevenness and irregularity on surfaces thereof to resemble natural human hair. 
     
     
         13 . The method of manufacturing the synthetic braiding hair in  claim 11  in which the step of pulling the plurality of the first synthetic fibers uses a gripper that alternately holds and releases one end of the plurality of the first synthetic fibers while combing the other end of the plurality of the first synthetic fibers with a combing table. 
     
     
         14 . The method of manufacturing the synthetic braiding hair in  claim 11  in which the step of pulling the plurality of the second synthetic fibers uses the gripper that alternately holds and releases one end of the plurality of the second synthetic fibers while combing the other end of the plurality of the second synthetic fibers with the combing table. 
     
     
         15 . The method of manufacturing the synthetic braiding hair in  claim 11  in which the step of creating a plurality of the combined synthetic fibers further includes setting the length of the plurality of the second synthetic fibers to be half of the length of the plurality of the first synthetic fibers. 
     
     
         16 . The method of manufacturing the synthetic braiding hair in  claim 11  in which the step of forming curly shape to the plurality of the combined synthetic fibers further includes submerging the plurality of the combined synthetic fibers into a hot water setting chamber of which the water temperature set to 100° C. 
     
     
         17 . The method of manufacturing the synthetic braiding hair in  claim 11  in which the separated plurality of the combined synthetic fibers should be an adequate amount that a braider can directly attach onto human hair.
