Hollow Fiber Structure of Aerogel and Method for Manufacturing the Hollow Fiber Structure

Abstract

A fiber structure includes a fiber thread including a plurality of monofilaments juxtaposed to and combined with each other. Each of the monofilaments has a hollow shape. Each of the monofilaments is made of an aerogel and an artificial polymer. The aerogel and the artificial polymer are mixed together.

1 . A fiber structure comprising:
 a fiber thread including a plurality of monofilaments juxtaposed to and combined with each other;   wherein:   each of the monofilaments has a hollow shape;   each of the monofilaments is made of an aerogel and an artificial polymer; and   the aerogel and the artificial polymer are mixed together.   
     
     
         2 . The fiber structure of  claim 1 , wherein the aerogel of each of the monofilaments has a mass proportion of 0.5-10%. 
     
     
         3 . The fiber structure of  claim 1 , wherein the artificial polymer of each of the monofilaments is made of PP, polyester, Nylon or acrylic. 
     
     
         4 . The fiber structure of  claim 1 , wherein the fiber thread has a specification of 70D/72F. 
     
     
         5 . A method for manufacturing a fiber structure, comprising:
 preparing a staple including an aerogel and an artificial polymer,   hot melting the staple into a spinning solution and spinning the spinning solution by a plurality of annular injection holes to form a plurality of hollow monofilaments, and   juxtaposing and combining the monofilaments into a fiber thread.   
     
     
         6 . The method of  claim 5 , wherein the step of preparing a staple includes obtaining powder of the aerogel and particles of the artificial polymer, and evenly mixing the powder of the aerogel and the particles of the artificial polymer to form the staple. 
     
     
         7 . The method of  claim 5 , wherein the step of preparing a staple includes adding powder of the aerogel and mixing the powder of the aerogel with the artificial polymer during polymerization of the artificial polymer to form the staple. 
     
     
         8 . The method of  claim 5 , further comprising:
 working the fiber thread after the step of juxtaposing and combining the monofilaments.
