Double-structure headwear and manufacturing method thereof

Abstract

A double-structure headwear and a manufacturing method thereof may provide improved productivity by easily forming the double-structure headwear and provide a shielding effect against external heat and wearing comfort. The double-structure headwear includes a first wearing portion, and a second wearing portion being disposed on an inner side of the first wearing portion. The first and second wearing portions have each lower portion sewed and folded to a predetermined height in a vertical direction, and the first wearing portion has a lower thermal conductivity and lower contact thermal sensation than that of the second wearing portion.

1 . A double-structure headwear comprising:
 a first wearing portion; and   a second wearing portion being disposed on an inner side of the first wearing portion,   wherein the first and second wearing portions have each lower portion folded to a predetermined height in a vertical direction and sewed to each other, and the first wearing portion has a lower thermal conductivity and lower contact thermal sensation than that of the second wearing portion.   
   
   
       2 . The double-structure headwear of  claim 1 , further comprising first and second core members respectively disposed on each folded lower portion. 
   
   
       3 . The double-structure headwear of  claim 1 , further comprising a size tape having a constant length and entirely disposed on each lower portion of the first and second wearing portions. 
   
   
       4 . The double-structure headwear of  claim 1 , wherein the second wearing portion is formed by polyester. 
   
   
       5 . The double-structure headwear of  claim 1 , wherein the second wearing portion is formed by a mixed spinning of cotton and polyester in a ratio of 6 to 4. 
   
   
       6 . The double-structure headwear of  claim 2 , wherein the first and second core members are formed by a non-woven fabric. 
   
   
       7 . The double-structure headwear of  claim 2 , wherein the first core member is thicker than the second core member. 
   
   
       8 . The double-structure headwear of  claim 7 , wherein the first and second core members are formed by about 100% polyester, the first core member has a thickness of about 1.0 mm and a weight of about 101.56 g/m 2 , and the second core member has a thickness of about 0.8 mm and a weight of about 78.12 g/m 2 . 
   
   
       9 . The double-structure headwear of  claim 3 , wherein the size tape has high elasticity in a vertical direction. 
   
   
       10 . The double-structure headwear of  claim 1 , wherein the first and second core members have sweat-absorptive and cushioning properties. 
   
   
       11 . The double-structure headwear of  claim 1 , wherein the first wearing portion has a seam portion for connecting a plurality of fabric pieces and being pre-sewed with each other and sewed in one-to-one with a tape of a predetermined width, and the second wearing portion has a seam portion for connecting a plurality of fabric pieces and being pre-sewed with each other. 
   
   
       12 . A manufacturing method of a double-structure headwear, comprising:
 forming a first wearing portion including pre-sewing a plurality of fabric pieces to form a seam portion, dividing the seam portion in one-to-one, and again sewing the divided sewing portion in one-to-one with a tape;   forming a second wearing portion including pre-sewing a plurality of fabric pieces having a higher thermal conductivity and higher contact thermal sensation than those of the first wearing portion;   folding each lower portion of the first and second wearing portions to a predetermined height to form each folded portion;   sewing in one-to-one each folded portion of the first and second wearing portions.   
   
   
       13 . The manufacturing method of  claim 12 , wherein the forming of the folded portions further comprises respectively disposing a first core member and a second core member thinner than the first core member on each lower portion of the first and second wearing portions, disposing a size tape on each lower portion of the first and second core members, and folding each lower portion of the first and second wearing portions along with each lower portion of the first and second core members by a width of the size tapes. 
   
   
       14 . The manufacturing method of  claim 12 , wherein the one-to-one sewing of the folded portions includes disposing one end of a visor portion between each folded portion of the first and second wearing portions, and entirely sewing the one end of the visor with the folded portions of the first and second wearing portions. 
   
   
       15 . The manufacturing method of  claim 13 , wherein the forming of the folded portions further comprises respectively stitching the first wearing portion, the first core member and the tip portion of the size tape along with the second wearing portion, the second core member, and the tip portion of the size tape. 
   
   
       16 . The manufacturing method of  claim 13 , wherein the first and second core members are formed of a non-woven fabric.
