fig2 is a partially cut view of a headwear according to the embodiment 1 of the present invention , and fig3 is a sectional view illustrating a sweat band of the headwear of fig2 . referring to fig2 and fig3 , the headwear is a cap 100 for a baseball player or a kid , which includes a crown 110 , a visor 120 and a sweat band 130 . the crown 110 is made up of plurality of gores 112 . the gores 112 are successively stitched one by one , to form a hemisphere - shaped crown 110 . two of the gores 112 are stitched to form an inseam . a bias tape 114 is provided over the inseam between two adjacent gores on the inner side of the crown 110 . also , the bias tape 114 helps to prevent the gores 112 from being deformed . each of the gores 112 includes a first stretchable fabric mainly composed of high twist yarn . the high twist yarn generally is made of non - stretchable fibers that are twisted over 800 times per meter . the high twist yarn has slight expansion properties . although the high twist yarn is made of non - stretchable fibers , it can expand and contract because of its high - twist structural feature . here , the high twist yarn is included in the gore 112 as weft or warp , otherwise at least as weft , to help the crown 110 to expand circumferentially . also , the gores 112 of this embodiment could be woven fabric , knitted fabric or non - woven fabric made of the high twist yarn . the visor 120 has rigid nature and is secured to a front portion of the crown 110 . it extends outwardly to protect a face or a neck from becoming sun burnt and eyes from sunlight . the sweat band 130 is attached to the inside of the crown 110 along its lower edge to fix the cap 100 on the head . the sweat band 130 absorbs sweat to prevent it from running down onto the face . particularly , the lower end portion of the crown 110 is inwardly bent , and the sweat band 130 is overlaid on . the lower edge of the crown 110 and the sweat band 130 are engaged with each other by the inwardly bent portion of the crown 110 . the lower end portions of the sweat band 130 and the crown 110 are wholly pressed and stitched together to form a stitch line 146 that encircles the crown 110 , parallel to its lower edge . the stitch line 146 is visible on the outer side of the crown 110 to provide an aesthetically pleasing appearance . the sweat band 130 includes a band core 132 therein . the band core 132 is partially covered by a second stretchable fabric 136 . the second stretchable fabric 136 is also mainly made of a high twist yarn described above or could include some elastic material like spandex , polyurethane , etc . when the second stretchable fabric includes elastic material , the second stretchable fabric 136 can stretch more elastically than the first stretchable fabric . the band core 132 is composed of soft materials . this allows the sweat band 130 to wrap softly around the head , so to reduce pressing force and provide a comfortable fit . also , the band core 132 helps to maintain the shape of the sweat band 130 . the band core 132 can be made of polyurethane foam , other resin foam , woven fabric , knit fabric and non - woven fabric . the second stretchable fabric 136 is disposed so that its weft direction is substantially parallel or somewhat inclined to the circumference of the sweat band 130 . the second stretchable fabric 136 would be interposed between the band core 132 and the head , when in use , and partially covers upper and lower end portions of the band core 132 , so to cover the inner face of the band core 132 . when the second stretchable fabric 136 is engaged with the band core 132 , the upper and lower end portions of the sweat band 130 are stitched with a stretchable yarn 142 and 144 . also , when the sweat band 130 is stitched to the crown 110 , a stretchable yarn also is preferably used , so to form a stitch line 146 . at this time , the lower end portions of the sweat band 130 and the crown 110 are wholly pressed and stitched together with the stretchable yarn , such that the stitch line 146 is visible on the outer side of the crown 110 and formed along the lower edge of the crown 110 . since the stretchable yarns for engaging the sweat band 130 and the crown 110 and for forming the stitch line 146 have stretchable properties , they can easily stretch corresponding to the expanding and contracting of the crown 110 and the sweat band 130 . thus , the stretchable yarns can regulate the appearance of the crown 110 , and the stitch line 146 , specially , can present the cap 100 with an aesthetically pleasing appearance . when the wearer puts on the cap 100 , the crown 110 and the sweat band 130 slightly expand so that it can accommodate a limited number of head sizes . as shown in fig3 , the lower end portion of the sweat band 130 is fixedly attached to the lower end portion of the crown 110 , while the upper portion of the sweat band 130 is separated from the inner side of the crown 110 . so , the upper portion of the sweat band 130 can move for a comfortable fit . in sum , because the sweat band 130 and the crown 110 include high twist yarns according to embodiment 1 , the cap 100 has an expanding property to a small degree . therefore the cap 100 has smaller restoring force than the conventional free size cap , thus leaving no indented mark on the forehead . additionally , the band core 132 made of a soft material makes the sweat band 130 wrap softly around the head , so to reduce the pressing force and provide a comfortable fit . in embodiment 1 , the cap 100 is described in detail as the headwear of the present invention . however , the headwear of the present invention might include a hat and ivy cap having a few panels , and a visor - type cap having a head band , etc ., and the above descriptions can help to understand other styles of headwear . fig4 is a partially cut view illustrating a sweat band and a crown of a headwear according to embodiment 2 of the present invention , and fig5 is a sectional view of the sweat band of the headwear . in the embodiment 2 , the headwear can be described with reference to the detail descriptions and drawings of the above embodiment , so that repeated descriptions and drawings may be omitted . referring to fig4 and fig5 , the headwear is cap 200 for a baseball player or a child , and the cap 200 includes a crown 210 , a visor and a sweat band 230 . the crown 210 is made up of plurality of gores 212 . the gores 212 are successively stitched one by one , to form a hemisphere - shaped crown 210 . two of the gores 212 are stitched to form an inseam . a bias tape 214 is provided over the inseam between two adjacent gores on the inner side of the crown 210 . also , the bias tape 214 helps to prevent the gores 212 from being deformed . each of the gores 212 includes a first stretchable fabric mainly composed of high twist yarn . the high twist yarn generally is made of non - stretchable fibers that are twisted over 800 times per meter . the high twist yarn has slight expansion properties . although the high twist yarn is made of non - stretchable fibers , it can expand and contract because of its high - twist structural feature . here , the high twist yarn is included in the gore 212 as weft or warp , otherwise at least as weft , to help the crown 210 to expand circumferentially . also , the gores 212 of this embodiment could be woven fabric , knitted fabric or non - woven fabric made of the high twist yarn . the visor 220 has rigid nature and is secured to a front portion of the crown 210 in a manner similar to that of the visor 120 of the first embodiment . it extends outwardly to protect a face or a neck from becoming sun burnt and eyes from sunlight . the sweat band 230 is attached to the inside of the crown 210 , along its lower edge . the sweat band 230 can fix the cap 200 on the head and absorb sweat to prevent it from running down on the face . particularly , the lower end portion of the crown 210 is partially folded to the inside and the sweat band 230 is overlaid on and stitched to the folded portion of the crown 210 . the lower end portions of the sweat band 230 and the crown 210 are stitched together to form a stitch line 246 that encircles the crown 210 and is parallel to its lower edge . the stitch line 246 is visible on the outer side of the crown 210 to provide an aesthetically pleasing appearance . the sweat band 230 includes a band core 232 therein , and the band core 232 is composed of a polyurethane form layer 233 inward and an elastic band layer 234 outward . the polyurethane form layer 233 is partially covered by a second stretchable fabric 236 to face the head . the second stretchable fabric 236 is mainly made of high twist yarn described above and could include some elastic material like spandex , polyurethane , etc . when the second stretchable fabric includes the elastic material , it can stretch more elastically than the first stretchable fabric . the polyurethane foam layer 233 is formed inside of the band core 232 and is made of very soft material . so , it makes the sweat band 230 wrap the head softly around the head , so to reduce pressing force and provide a comfortable fit . also , the polyurethane foam layer 233 helps to maintain the shape of the sweat band 230 , when not in use . the elastic band layer 234 is formed outside of the band core 232 and is made of elastic material , so to provide a proper restoring force . the second stretchable fabric 236 is disposed so that its weft direction is substantially parallel or somewhat inclined to the circumference of the sweat band 230 . the second stretchable fabric 236 would be interposed between the band core 232 and the head , when in use , and partially covers upper and lower end portions of the band core 232 , so to cover the inner face of the band core 232 . when the second stretchable fabric 236 is engaged with the band core 232 , the upper and lower end portions of the sweat band 230 are stitched with a stretchable yarn 242 and 244 . also , when the sweat band 230 is stitched to the crown 210 , a stretchable yarn is preferably used , so to form a stitch line 246 . at this time , the lower end portions of the sweat band 230 and the crown 210 are stitched together and the stitch line 246 is formed adjacent to and parallel to along the lower edge of the crown 210 . since the stitch line 246 is made of a stretchable yarn , they can stretch corresponding to the expanding and contracting of the crown 210 and the sweat band 230 . the stitch 246 can regulate the appearance of the lower end portion of the crown 210 to present the cap 200 with an aesthetically pleasing appearance . a shape tape 218 is attached circumferentially to the crown 210 , adjacent to the lower edge thereof . the shape tape 218 is stitched along the folded portion of the crown 210 . as the wearer puts on and takes off the cap repeatedly , the crown 210 also expands and contracts repeatedly , in which case the crown 210 is likely to become deformed and wrinkled . in order to prevent the cap from becoming deformed and / or wrinkled , the shape tape 218 is stitched circumferentially to the crown 210 . as shown in fig4 , the shape tape 218 has a free upper portion 218 a not attached to the crown 210 or the sweat band 230 . also , a top portion of the shape tape 218 does not contact the crown 210 or the sweat band 230 . referring to fig5 , when the wearer puts on the cap , the crown 210 and the sweat band 230 slightly expand so that it can accommodate a limited number of head sizes . the lower end portion of the sweat band 230 is fixedly attached to the lower end portion of the crown 210 , while the upper portion of the sweat band 230 is separated from the inner side of the crown 210 . so , the upper portion of the sweat band 230 can additionally move for a comfortable fit . because the sweat band 230 and the crown 210 include high twist yarns , the cap can expand circumferentially to a small degree . also , the cap according to the present invention has smaller restoring force than the conventional free size cap , thus leaving no indent mark on the wearer &# 39 ; s forehead . moreover , the sweat band 230 including the soft band core 232 wraps softly around the head , so to reduce the pressing force and provide a comfortable fit . although the preferred embodiments of the present invention have been described , it is understood that the present invention should not be limited to those preferred embodiments , but various changes and modifications can be made by one skilled in the art within the spirit and scope of the invention as hereinafter claimed .
