  When the foamed resin elastomer disclosed in Patent Document 1 is used, there is a problem in terms of air permeability. In general, a hat is desired to be excellent in breathability, easy to wash, and lightweight. However, although the thing of patent document 1 is provided with a predetermined characteristic in the point of impact absorption, it is far inferior to a general cap in terms of breathability, easy washing, and lightness. On the other hand, the three-dimensional solid knitted fabric used for the disaster hood of Patent Document 2 has not only excellent shock absorption characteristics but also light weight, excellent breathability, and easy washing. Yes. Therefore, if such a three-dimensional solid knitted fabric is used as a cushioning material, a hat suitable not only for adults but also as a head protection cap for children can be provided.

  However, it is difficult to process a three-dimensional solid knitted fabric into a hemisphere like a hat. Generally, it is conceivable to cut into a predetermined shape and process it into a hemispherical shape by sewing, but the manufacturing process becomes complicated and the manufacturing cost increases. On the other hand, processing into a hemisphere by using the heat compression molding method described in Patent Documents 3 to 5 can be considered, but the techniques described in Patent Documents 3 to 5 have the following problems. That is, when a three-dimensional solid knitted fabric is heat-compressed and molded into a predetermined molded product, the three-dimensional solid knitted fabric constituting the molded product is thinner than before molding, and the compression recovery property is also deteriorated. In view of this point, in Patent Document 5, a three-dimensional solid knitted fabric to be processed is used which has special fabric characteristics and the like, and the compression / restorability is improved. Not achieved. In addition, the heat compression mold is expensive to manufacture and requires a long manufacturing period.

  The present invention has been made in view of the above, and by using a three-dimensional solid knitted fabric, while satisfying the conditions required for a general hat such as lightness, breathability, and easy washing, high impact is achieved at a low manufacturing cost. It is an object of the present invention to provide a cap manufacturing method and a cap that can exhibit absorption characteristics and are suitable for head protection.

In order to solve the above-mentioned problem, in the present invention according to claim 1, the end of the three-dimensional solid knitted material cut into a predetermined shape is locked to the upper mold and the lower mold, and the substantially hemispherical shape excluding the end The molded part is set between the upper mold and the lower mold in a non-pressurized state that is not pressurized by the upper mold and the lower mold and heat-treated, and the shape molded part is deformed along the inner surfaces of the upper mold and the lower mold. a step of forming by,

The invention according to claim 8 provides the cap according to claim 6 or 7, wherein the elastic intermediate member is formed of a three-dimensional solid knitted fabric.

  In the present invention, the end portion of the three-dimensional solid knitted fabric cut into a predetermined shape is locked to the upper die and the lower die, and the portion excluding the end portion is not pressed by the upper die and the lower die. It is set between an upper mold and a lower mold and is formed into a hat shape. The three-dimensional solid knitted fabric to be processed is knitted and then heat-set to be provided as a flat plate-shaped original fabric. Since heat set is used to correct and smooth the unevenness of the surface when knitting, by performing heat setting, the ground and the connecting yarn are heated in a state where they are pressed in the thickness direction more than when knitting. It has been transformed. In the present invention, the three-dimensional solid knitted fabric thus provided is heated by being set between the upper die and the lower die in a non-pressurized state. The residual stress of the ground and the connecting yarn is released between the upper mold and the lower mold, so to speak, it deforms along the mold in an attempt to deform to the state at the time of knitting before heat setting. Therefore, the obtained cap has a thickness almost the same as or thicker than that of the three-dimensional solid knitted fabric before processing, and is not formed by heating and compression, so that a high compression recovery property is obtained. Can exhibit high shock absorption characteristics and is suitable for head protection.

  In addition, when the rubber member is provided along the circumference near the boundary between the end portion and the substantially hemispherical shape forming portion, the shape of the shape forming portion can be maintained by the rubber member, By utilizing the elongation of the three-dimensional solid knitted fabric, it is possible to provide hats corresponding to various head sizes while having a constant size. That is, when the shape forming portion is heat compression formed, the ground and the connecting yarn are cured, so that the circumferential extension is also limited. However, according to the present invention, the shape forming portion is formed without pressure. The stretchability of the three-dimensional solid knitted fabric can be retained even after molding, and by attaching a rubber member, the shape molded part can be fitted to the head even in the circumferential direction, So-called free size corresponding to the head size or a hat close to it can be provided. Further, by providing one or more laminated elastic intermediate materials, preferably a three-dimensional solid knitted material, on the inner surface side of the shape forming portion, the impact absorbing characteristics in the shape forming portion are further improved. be able to. Further, the elastic intermediate material is not limited to a hat made of a three-dimensional solid knitted fabric, and the impact absorbing characteristics can be improved even when used for a cloth hat.

  Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. 1 and 2 are diagrams showing the manufacturing process of this embodiment. As shown in these drawings, first, the three-dimensional solid knitted fabric 10 to be processed may be cut into an arbitrary shape that can be easily set in the mold 20, such as a substantially rectangular shape or a substantially circular shape. The edge part may be cut afterwards so as to obtain a desired hat shape, but the shape can be obtained only by molding so that the desired hat shape can be obtained, or the cutting process after molding can be simplified as much as possible. Any shape that has been cut in advance may be used.

  Here, the three-dimensional three-dimensional knitted fabric 10 is a three-dimensional tertiary knitted fabric having a pair of ground knitted fabrics spaced apart from each other and a large number of connecting yarns that reciprocate between the pair of ground knitted fabrics to couple them together. The knitted fabric has the original structure. One ground knitted fabric is formed by, for example, a flat knitted fabric structure (fine stitches) that is continuous in both the wale direction and the course direction from a yarn obtained by twisting a single fiber. For example, a knitted structure having a honeycomb-shaped (hexagonal) mesh is formed from a yarn obtained by twisting short fibers. Of course, this knitted fabric structure is arbitrary, and it is also possible to adopt a knitted fabric structure other than a fine structure or a honeycomb shape, and a combination thereof is also arbitrary, such as adopting a fine structure for both. The connecting yarn is knitted between the pair of ground knitted fabrics such that one ground knitted fabric and the other ground knitted fabric maintain a predetermined distance, and gives a predetermined rigidity to the three-dimensional solid knitted fabric. . The thickness of the ground yarn forming the ground knitted fabric is selected so that the waist strength necessary for the three-dimensional solid knitted fabric can be provided and the knitting operation does not become difficult.

  Examples of the material of the ground yarn or the connecting yarn include synthetic fibers such as polypropylene, polyester, polyamide, polyacrylonitrile, and rayon, and natural fibers such as recycled fibers, wool, silk, and cotton. These materials are used alone. These may be used in combination. Preferably, thermoplastic polyester resins represented by polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polyamide resins represented by nylon 6 and nylon 66, and polyolefin resins represented by polyethylene and polypropylene Or polytrimethylene terephthalate (PTT) or a resin obtained by mixing two or more of these resins. Polyester resins are suitable because of their excellent recyclability. Further, the shape of the ground yarn or the connecting yarn is not limited, and may be a round cross-section yarn or a modified cross-section yarn.

  The connecting yarn may be formed in a loop-like stitch in the ground knitted fabric of the surface layer and the back layer, or may be structured to be hooked on the ground knitted fabric of the surface layer and the back layer by the insertion structure, but at least two connecting yarns However, in order to improve the form stability of the three-dimensional solid knitted fabric, it is preferable that the knitted fabrics of the surface layer and the back layer are inclined obliquely in opposite directions and connected in a cross shape (X shape) or a truss shape.

  The three-dimensional knitted fabric can be knitted with a knitting machine having two rows of needle beds facing each other. Examples of such a knitting machine include a double raschel knitting machine, a double circular knitting machine, and a flat knitting machine having a V bed. In order to obtain a three-dimensional solid knitted fabric with good dimensional stability, it is preferable to use a double raschel knitting machine. The three-dimensional knitted fabric finishes the knitted raw machine through processes such as scouring, dyeing and heat setting. The heat setting is performed, for example, by dry heat at 150 ° C. for 1 minute, and finished into a flat plate having a smooth surface. The three-dimensional solid knitted fabric that has been subjected to the finishing process is wound as a roll and provided as an original fabric, for example. In the present embodiment, the original fabric wound in a roll shape is drawn out for a predetermined length and cut into a predetermined shape as described above.

  The three-dimensional three-dimensional knitted fabric 10 cut into a predetermined shape is set between an upper mold 21 and a lower mold 22 constituting the mold 20 as shown in FIG. Here, the lower mold | type 22 is equipped with the hemispherical convex part 22b which protrudes upwards in the approximate center part, The peripheral edge becomes the taper-shaped edge part latching surface 22a. On the other hand, the upper die 21 is provided with a hemispherical concave portion 21b at a position facing the hemispherical convex portion 22b of the lower die 22, and the back surface of the peripheral edge is a tapered shape facing the end locking surface 22a of the lower die 22. This is an end locking surface 21a.

  When setting the three-dimensional solid knitted fabric 10, the vicinity of the end 11 of the peripheral edge is locked to the end locking surfaces 21 a and 22 a of the upper mold 21 and the lower mold 22. The means for locking the vicinity of the end portion 11 is arbitrary. For example, the end portion locking surfaces 21a and 22a where the vicinity of the end portion 11 is positioned can be locked using a pin member or the like. As shown in FIG. 1B and FIG. 2, the distance between the end locking surfaces 21a and 22a of the upper mold 21 and the lower mold 22 is made smaller than the thickness of the three-dimensional solid knitted fabric 10 to be processed. By adjusting, it is preferable that the end portion locking surfaces 21a and 22a are nipped and locked. When the gap between the end locking surfaces 21a and 22a is pinched with being narrower than the thickness of the three-dimensional solid knitted fabric 10, the portion has a thickness after molding that is greater than that before the processing of the three-dimensional solid knitted fabric 10. Since the thickness is reduced and the hardness is increased, the vicinity of the end portion 11 can be used as a collar portion of the hat.

  The hemispherical concave portion 21b and the hemispherical convex portion 22b of the upper mold 21 and the lower mold 22 for molding a portion other than the end portion 11 (hereinafter referred to as “shape molding portion”) 12 sandwiched between the end locking surfaces 21a and 22a are as follows. At the time of forming, the shape forming portion 12 of the three-dimensional solid knitted fabric 10 is set at intervals that do not pressurize. That is, as shown in FIG. 1B and FIG. 2, the distance between the hemispherical concave portion 21b and the hemispherical convex portion 22b is substantially equal to or wider than the thickness of the three-dimensional solid knitted fabric 10 to be processed. Set by. The upper mold 21 and the lower mold 22 are set in such a state, but the set positions are fixed by appropriate engagement means or the like so as to maintain the set state during processing. Of course.

  Next, as shown in FIG. 1B, the three-dimensional solid knitted fabric 10 set in the mold 20 is accommodated in, for example, a heating furnace 30 and heat-treated. Since the three-dimensional solid knitted fabric 10 is set so that the shape forming portion 12 is not pressurized by the hemispherical concave portion 21b and the hemispherical convex portion 22b of the upper mold 21 and the lower mold 22 as described above, the three-dimensional solid knitted fabric 10 The ground yarn and the connecting yarn of the ground knitted fabric constituting the fabric are deformed by the residual stress until the form is stabilized so that the thermal deformation at the time of heat setting is released. As a result, the shape forming portion 12 of the three-dimensional solid knitted fabric is deformed into a substantially hemispherical shape along the inner surface of the mold between the hemispherical concave portion 21b and the hemispherical convex portion 22b even though it is not pressurized.

  On the other hand, the end 11 held between the end locking surfaces 21a and 22a is adjusted to be narrower than the thickness of the three-dimensional solid knitted fabric 10 before processing in the present embodiment. The deformation of the ground yarn and the connecting yarn of the portion 11 is in the surface direction and is deformed so as to be thinner than the thickness of the three-dimensional solid knitted fabric 10 before processing. Since the end portion 11 is deformed in this manner, the elasticity in the thickness direction is smaller than that of the shape forming portion 12 and the hardness is increased. Therefore, by cutting this portion into a predetermined shape, it can be used as it is.

  In addition, it is preferable to manufacture the upper mold | type 21 and the lower mold | type 22 which comprise the metal mold | die 20 using a material with high heat conductivity. Further, unlike conventional heat compression molding, it is not necessary to conform to the shape of the mold by the pressing force of the mold 20, so that it can be easily manufactured using punching metal.

  In addition, the heating temperature in the present embodiment varies depending on the heating time, the thickness of the three-dimensional solid knitted fabric, and the like, but is equal to or higher than the temperature at the time of heat setting and forms the three-dimensional solid knitted fabric 10. It is preferable to set the heating temperature to 140 to 170 ° C. for a heating time of 3 to 5 minutes or less.

  After the heat treatment, for example, forced cooling is performed until the temperature reaches about 80 ° C. or less, and when the upper die 21 is removed and removed as shown in FIG. 1 (c), a predetermined value is obtained as shown in FIG. 1 (d). A hat 50 made of a three-dimensional solid knitted fabric of the shape is obtained. Since the obtained hat 50 is molded as described above, the thickness of the substantially hemispherical shape molding portion 12 is not thinner than before processing, and conversely, between the upper mold 21 and the lower mold 22. Depending on the gap, it becomes thicker than before processing, close to the thickness at the time of knitting before heat setting, and the elasticity and compression recovery in the thickness direction are almost equal to or higher than before processing. That is, the hemispherical shape forming part 12 is excellent for protecting the head because it can exhibit the elasticity and the like of the three-dimensional solid knitted fabric 10 before processing as it is. Further, the three-dimensional solid knitted fabric 10 can be easily washed as it is, and is suitable for a hat in terms of easy washing, breathability and light weight.

  The hat 50 molded in this way is used as a collar by cutting the end 11 into a predetermined shape. For example, as shown in FIG. 3, it may have a shape in which a collar is formed over the entire circumferential direction, or a baseball cap in which a collar is formed only in the front as shown in FIG. It can also be a shape. Moreover, in the boundary part of the edge part 11 which forms a collar part, and the substantially hemispherical shape shaping | molding part 12, as shown to FIG. 3B and FIG. It is preferable that the belt-like rubber member 60 is attached to the belt by sewing or the like. The rubber member 60 functions as a bottle skin, but the substantially hemispherical shape forming portion 12 maintains the elasticity and the like of the three-dimensional solid knitted fabric 10 before processing as described above. Therefore, high stretchability is also maintained in the circumferential direction due to the deformation of the ground stitch constituting the three-dimensional solid knitted fabric 10 and the fall of the connecting yarn. Therefore, when the rubber member 60 is attached in a circumferential shape, the cap member is stretched according to the size of the head in the wearing state, and when the cap is removed, the substantially hemispherical shape forming portion 12 is formed by the elastic force of the rubber member 60. Return to keep the shape of. That is, by providing this rubber member 60, it can respond to various head sizes, and even if the size with the rubber member 60 attached is constant, it can respond to various head sizes. Can be a close hat. Further, the rubber member 60 as a bottle skin is usually used in a state where the rubber member 60 is sewn at the boundary between the end portion 11 forming the collar portion and the substantially hemispherical shape forming portion 12 and is along the inner peripheral surface. If this is folded 180 degrees and mounted on the head so as to protrude below the boundary portion, the contact area with the head is increased, so that the function of preventing falling off during a fall or the like can be enhanced.

  In addition, when the edge 11 of the collar 11 is bent once or twice or more and covered with the covering cloth material 11a and stitched together, the periphery of the collar 11 is strengthened, which helps to maintain the shape of the collar.

  The hat 50 of the above embodiment is excellent in shock absorption because the shape forming portion 12 and the like are formed from the three-dimensional solid knitted fabric 10, but in order to further improve the shock absorption, the shape forming portion 12 5 (a) and 5 (b), it is preferable to provide an elastic intermediate material 70. The elastic intermediate material 70 may be a thin cushion material, but it is preferable to use a three-dimensional solid knitted fabric because it is excellent in both shock absorption and air permeability. Further, as the elastic intermediate member 70, one cushion material such as a three-dimensional solid knitted fabric may be used, or a plurality of laminated elastic layers may be used. The shape is arbitrary, but is preferably formed in a circular shape so as to be easily arranged on the inner surface side of the shape forming portion 12. The elastic intermediate member 70 can fix at least a part of the periphery to the inner surface side of the shape forming portion 12 by sewing or the like. However, it is possible to arrange the shape forming portion 12 without being fixed to the inner surface side and to wear it on the head as it is.

  Here, (A) the hat 50 according to the above embodiment (hereinafter referred to as “net hat”), and (B) the elastic intermediate member 70 provided on the inner surface side of the hat 50 according to the above embodiment (hereinafter referred to as “net hat”). The impact test was conducted on “+ medium net”. For comparison, the same impact is applied to (C) a commonly used schoolchildren hat (hereinafter “schoolchild hat”) and (D) 12 mm thick slab urethane (hereinafter “12 mm slab urethane”).
