A reinforcing fabric 52 is arranged to cover the proximal edge 51a, and a piping process is applied to prevent fraying. An eaves core 53 is disposed over the entire surface between the eaves outer material 50 and the eaves lining 51. This eaves core 53 plays a role in maintaining the shape of the eaves portion 5 (in this embodiment, an arcuate shape in plan view), and is made of silicone resin. The materials for the eaves outer material 50, the eaves lining 51, and the reinforcing fabric 52 are not particularly limited, but may be any sheet-like material that can be used for clothing, such as woven fabrics, knitted fabrics, nonwoven fabrics, and film materials. Furthermore, all fibers usable for clothing may be used for woven fabrics, knitted fabrics, nonwoven fabrics, etc., such as natural fibers, recycled fibers, synthetic fibers, and mixtures thereof.

By the way, the silicone resin forming the eaves core 53 has higher heat resistance and excellent flexibility than polyethylene resin. Therefore, even if the dustproof hood 1 is washed and dried using a commercial washing machine, there is a low possibility that the silicone resin will crack or melt due to its high heat resistance. There is less possibility of problems such as cracking or bending occurring. Furthermore, even if the wearer H tampers with the eaves section 5 during work, it is less likely to cause problems such as cracking or bending the eaves section 5 due to its excellent flexibility. Become.

If the eaves core 53 is made of silicone resin, it becomes possible to continue to maintain the shape of the eaves section 5, thereby improving the ability to maintain the shape of the eaves section 5. I can do it.

On the other hand, since the silicone resin forming the eaves core 53 has excellent flexibility, if the eaves core 53 is not firmly fixed between the eaves outer material 50 and the eaves lining 51, There is a possibility that the eaves core 53 is biased toward either the upper part 5a side, the lower part 5b side, the left side part 5c side, or the right side part 5d side of the eave part 5 shown in FIG.

Therefore, in this embodiment, as shown in FIG. 4, the eaves stitch 54 is formed. This eaves stitch 54 is composed of a plurality of stitches, and specifically, it is composed of a first eave section stitch 54a and a second eave section stitch 54b. As shown in FIG. 4, the first eaves stitch 54a is formed in an arc shape from the left side 5c of the eave 5 toward the right side 5d. However, in forming such an arc shape, as shown in FIG. 3(b), it is formed by sewing the eaves core 53 to the eaves outer material 50 and the eaves lining 51 with sewing thread. .

On the other hand, as shown in FIG. 4, the second eave section stitch 54b intersects with the first eave section stitch 54a from the left side 5c of the upper part 5a of the eave section 5 toward the right side 5d of the upper part 5a. It is formed in an arc shape. However, in forming such an arc shape, as shown in FIG. 3(b), it is formed by sewing the eaves core 53 to the eaves outer material 50 and the eaves lining 51 with sewing thread. .

Thus, the first eave part stitch 54a and the second eave part stitch 54b as described above are formed, and the formed first eave part stitch 54a and second eave part stitch 54b are As shown in FIG. 4, by intersecting the left side 5c and the right side 5d of the eaves section 5, the left side and right side of the eaves core 53 are firmly fixed to the eaves outer material 50 and the eaves lining 51. It will be done. As a result, the eaves core 53 can be firmly fixed between the eaves outer material 50 and the eaves lining 51, so that the eaves core 53 can be fixed firmly between the eaves outer material 50 and the eaves lining 51. It is possible to reduce the situation where the position is biased toward either the side or the right side 5d.

The ear portions 6 are for hooking the strings of the mask (not shown), and are formed in a circular shape as shown in FIGS. 1 to 3(a). (see a)) are each sewn with sewing thread. As shown in FIG. 3(b), such an ear part 6 has an ear outer material 60 and an ear lining 61, and the proximal edge 60a of the ear outer material 60 and the ear lining 61. A reinforcing fabric 62 is arranged to cover the proximal edge 61a, and a piping process is applied to prevent fraying. An ear core 63 is disposed over the entire surface between the ear outer material 60 and the ear lining 61. The ear core 63 plays a role in maintaining the shape of the ear portion 6 (circular in this embodiment), and is made of silicone resin. The materials of the ear outer material 60, the ear lining 61, and the reinforcing fabric 62 are not particularly limited, but may be any sheet-like material that can be used for clothing, such as woven fabrics, knitted fabrics, nonwoven fabrics, and film materials. Furthermore, all fibers usable for clothing may be used for woven fabrics, knitted fabrics, nonwoven fabrics, etc., such as natural fibers, recycled fibers, synthetic fibers, and mixtures thereof.

By the way, the silicone resin forming the ear core 63 has higher heat resistance and excellent flexibility than polyethylene resin. Therefore, even if the dustproof hood 1 is washed and dried using a commercial washing machine, there is a low possibility that the silicone resin will crack or melt due to its high heat resistance. There is less possibility of problems such as cracking or bending occurring. Furthermore, even if the wearer H plays with the ear parts 6 during work, since the ear parts 6 are highly flexible, there is a low possibility that problems such as cracking or bending of the ear parts 6 will occur. Become.

However, if the ear core 63 is made of silicone resin, it becomes possible to continue to maintain the shape of the ear portion 6, thereby improving the shape retention of the ear portion 6. I can do it.

On the other hand, since the silicone resin forming the ear core 63 has excellent flexibility, if the ear core 63 is not firmly fixed between the ear outer material 60 and the ear lining 61, There is a possibility that the ear core 63 will be biased to either the upper part 6a side, the lower part 6b side, the left side part 6c side, or the right side part 6d side of the ear part 6 shown in the enlarged view of the X part indicated by the two-dot chain line in FIG. There is.

Therefore, in this embodiment, as shown in FIG. 2, ear stitches 64 are formed. This ear stitch 64 is composed of a plurality of stitches, and specifically, it is composed of a first ear stitch 64a and a second ear stitch 64b. As shown in FIG. 2, the first selvage stitch 64a is arranged in a concentric circle with the reinforcing fabric 62 on the inner side of the reinforcing fabric 62 that has been subjected to the piping process (on the side of the center point O of the selvedge 6 shown in FIG. 2). It is formed into a circular shape with a diameter smaller than that of the reinforcing fabric 62. However, in forming such a circular shape, as shown in FIG. 3(b), it is formed by sewing the ear core 63 to the ear outer material 60 and the ear lining 61 with sewing thread. .

On the other hand, as shown in FIG. 2, the second ear stitch 64b is located inside the first ear stitch 64a at an appropriate distance (on the side of the center point O of the ear 6 shown in FIG. 2). It is formed in a circular shape that is concentric with the ear stitch 64a and has a smaller diameter than the first ear stitch 64a. However, in forming such a circular shape, as shown in FIG. 3(b), it is formed by sewing the ear core 63 to the ear outer material 60 and the ear lining 61 with sewing thread. .

Thus, the first ear stitch 64a and the second ear stitch 64b as described above are formed, and the formed first ear stitch 64a and second ear stitch 64b are As shown in FIG. 2, since they are formed in a circular shape at appropriate intervals to match the shape of the ear part 6, the ear core 63 is firmly fixed to the ear outer material 60 and the ear lining 61 as a whole. becomes. Thereby, the ear core 63 can be firmly fixed between the ear outer material 60 and the ear lining 61, so that the ear core 63 can be firmly fixed between the ear outer material 60 and the ear lining 61. It is possible to reduce the situation where the position is biased toward either the side or the right side 6d.

By the way, the ear portion 6 is a portion on which a string of a mask (not shown) is hooked, and is therefore a portion that is frequently subjected to load. Therefore, in this embodiment, since the ear core 63 is firmly fixed as a whole by the ear outer material 60 and the ear lining 61, as shown in FIG. A crossing stitch 65 is formed to intersect with the crossing stitch 64b. This crossing stitch 65 is composed of a plurality of stitches, and specifically, it is composed of a first crossing stitch 65a and a second crossing stitch 65b. The first crossing stitch 65a and the second crossing stitch 65b are formed in a straight line, and are formed in a cross shape so as to intersect at the center point O of the ear portion 6. Thereby, the first crossing stitch 65a and the second crossing stitch 65b intersect with the first ear stitch 64a and the second ear stitch 64b. In addition, in forming such a first crossing stitch 65a and a second crossing stitch 65b, as shown in FIG. It will be formed by attaching it.

Thus, the first crossing stitch 65a and the second crossing stitch 65b as described above are formed, and the formed first crossing stitch 65a and second crossing stitch 65b are shown in FIG. Since the first ear stitch 64a and the second ear stitch 64b are formed to intersect with each other, the ear core 63 is firmly fixed as a whole by the ear outer material 60 and the ear lining 61. The Rukoto. Therefore, even if a load is frequently applied to the ear part 6, the ear core 63 can be securely fixed between the ear outer material 60 and the ear lining 61, so that the ear core 63 can be firmly fixed to the ear part 60. It is possible to reduce the situation where the position is biased toward either the upper part 6a side, the lower part 6b side, the left side part 6c side, or the right side part 6d side of 6.

Therefore, according to the present embodiment described above, it is possible to improve the shape retention of the eaves portion 5 and the ear portion 6.

Note that the shapes shown in this embodiment are merely examples, and various modifications and changes can be made within the scope of the gist of the present invention as described in the claims. For example, in this embodiment, an example is shown in which the ear portion 6 is formed in a circular shape, but the shape is not limited thereto, and any shape such as a rectangular shape, an ellipse shape, a triangular shape, etc. may be used. At this time, the shapes of the first ear stitch 64a and the second ear stitch 64b are determined according to the shape of the ear 6 (if it is rectangular, it is called rectangular, and if it is oval, it is called elliptical). It is preferable that they be formed annularly at appropriate intervals.

Further, in this embodiment, an example is shown in which the eaves stitch 54, the ear stitch 64, and the crossing stitch 65 are composed of a plurality of stitches, but the present invention is not limited to this, and they may be composed of a single stitch. Also good. However, if it is composed of a single stitch, there is a possibility that the sewing thread will melt and the stitch will disappear when used in a commercial washing machine, so it is preferable to compose it with two or more stitches. .
