Description

Technical Field

[0001] The utility model relates to the field of activated carbon clothing, in particular to an activated carbon crotch and activated carbon underwear. Background Art

[0002] The existing technology often adds activated carbon fiber sheets to underwear to achieve the effect of removing odor. For example, the patent with application number 201310645236.6 discloses a multifunctional health-care underwear, which sets an activated carbon fiber cloth layer in the underwear to filter out the odor secreted by the human body. The patent with application number 201921688778.0 discloses a men's underwear with antibacterial and health-care functions. Its antibacterial and health-care layer is composed of a silver ion fiber layer, a physiotherapy magnet and an activated carbon fiber sheet, and the activated carbon fiber sheet is used to adsorb odors. The patent with application number 202223560991.8 discloses a men's underwear, which is made of two layers of pure cotton material wrapped with an activated carbon material layer, and sterilizes and deodorizes by activated carbon.

[0003] However, during the sewing process of the activated carbon fiber sheet, the addition of the activated carbon fiber sheet will increase the foreign body sensation in the underwear, resulting in poor comfort. In order to ensure the effect of the activated carbon fiber sheet, it needs to have a certain thickness. When its edge is sewn together with the upper and lower layers of fabric, a higher step will be formed, which increases the sense of friction. At the same time, a part of the activated carbon fiber sheet is exposed, and the exposed fiber layer may shed powder or drop fine fibers. In addition, due to the different elasticity of commonly used fabrics and activated carbon fiber sheets, when the underwear is hemmed, when the activated carbon fiber sheet is hemmed together or when the activated carbon fiber sheet is close to the sewing area of ​​the upper and lower layers of fabric being hemmed, the fabric needs to be flattened during the hemming process. After the upper and lower layers of fabric and the middle layer of activated carbon fiber are flattened and sewn, wrinkles are likely to appear due to the difference in deformation ability, and the foreign body sensation is enhanced. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, method scheme and advantages of the embodiments of the present invention clearer, the method scheme in the embodiments of the present invention is clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0030] The activated carbon fiber sheet in activated carbon underwear is generally located in the crotch of the underwear. During exercise, the crotch edge of the underwear rubs against the thigh more frequently than the rest of the wearer's body. Therefore, to ensure the wearer's comfort, the height difference between the crotch edge and the rest of the crotch should not be too high. In the process of developing activated carbon underwear, the applicant first conceived a solution that overlapped the activated carbon fiber sheet, the first bottom crotch sheet, and the second bottom crotch sheet, and then directly sewed the edges of the three together. It was finally found that the step edge formed by the sewed edges was relatively high, which reduced the wearing comfort. At the same time, the activated carbon fiber sheet exposed at the edge would also shed powder or fine fibers. Reducing the thickness of the activated carbon fiber sheet would affect the sterilization and deodorization effects. The optimal thickness of the activated carbon fiber sheet is greater than 1.5 mm. Therefore, the applicant conceived a second solution. While keeping the thickness of the activated carbon fiber sheet unchanged, the first bottom crotch sheet and the second bottom crotch sheet are first sewn and at least one opening is left for placing the activated carbon fiber sheet. Finally, the opening is sewn up, which reduces the discomfort caused by the thicker edge. At the same time, the activated carbon fiber sheet will not be exposed from the sewing line, avoiding the loss of powder or fine fibers. However, during the lock-hemming sewing process, it was found that wrinkles are prone to occur at the end of the lock-hemming, especially when an elastic band is set at the edge of the thigh opening of the activated carbon underwear, the wrinkles are more serious. Therefore, the applicant thought about how to avoid the occurrence of wrinkles during the lock-hemming process and increase comfort, and finally conceived a third technical solution, as shown in the following embodiments.

[0031] Example 1: Figure 1-2 As shown, an activated carbon crotch comprises: a first bottom crotch piece 1, a second bottom crotch piece 2 and an activated carbon fiber sheet 3, the first bottom crotch piece 1 overlaps with the second bottom crotch piece 2, the edge of the first bottom crotch piece 1 is sewn and connected with the edge of the second bottom crotch piece 2 to form a sewing area, the activated carbon fiber sheet 3 is located between the first bottom crotch piece 1 and the second bottom crotch piece 2, the first bottom crotch piece 1 and / or the second bottom crotch piece 2 is sewn and connected with the activated carbon fiber sheet 3, the sewing area comprises an elastic sewing area 4, the elastic deformation ability of the fabric of the elastic sewing area 4 is greater than the elastic deformation ability of the activated carbon fiber sheet.

[0032] During the specific implementation process, the sewing area between the first bottom crotch piece and the second bottom crotch piece refers to the step area formed after sewing along the edges of the two during the lock-stitching process. Since the edge of the activated carbon fiber sheet and the edges of the two bottom crotch pieces in the utility model are no longer overlapped and sewn together, the thickness of the step area will not be too high, and the comfort when wearing is better. At the same time, in order to ensure the comfort of the thigh opening of the underwear, the stability of wearing and the adaptability to the wearer's thigh shape, elastic fibers or elasticity are often used at the edge of the bottom crotch piece serving as the thigh opening. Therefore, when flattened during the sewing process, its elastic deformation ability is greater than that of the activated carbon fiber sheet. If the activated carbon fiber sheet is sewn together with the two bottom crotch pieces, the activated carbon fiber sheet will participate in the process of flattening and extending the fabric. The difference in elastic deformation ability of each surface layer will cause wrinkles to form on the crotch surface during the shrinkage process of each surface layer after the lock-stitching is completed.

[0033] For example, when sewing, first cut the first bottom crotch piece 1, the second bottom crotch piece 2 and the activated carbon fiber sheet 3 into a certain shape or size according to the process requirements. The shape and size of the first bottom crotch piece 1 and the second bottom crotch piece 2 can be exactly the same, and the shapes of the two can refer to Figure 2 As shown in the figure, its upper and lower ends are used to connect with the front piece 7 and the back piece 8, and the left and right ends serve as the edges of the thigh opening. First, sew the three sides of the first bottom crotch piece 1 and the second bottom crotch piece 2 to obtain a bag with an opening, then put the activated carbon fiber sheet 3 into the bag and sew it to the first bottom crotch piece 1 and the second bottom crotch piece 2 along the edge of the activated carbon fiber sheet 3, and finally sew the opening of the bag. The opening end of the bag can be selected as follows Figure 2 The left end or right end shown, the unsewn end refers to the end that is not sutured, that is, the open end.

[0034] Example 2: In order to further reduce the possibility of wrinkles, improvements were made based on Example 1, such as Figure 2 As shown, there is a gap between the edge of the activated carbon fiber sheet 3 and the elastic sewing area 4.

[0035] In the specific implementation process, the crotch has two opposite ends connected to the front piece 7 and the back piece 8 respectively, and the other two ends form the edges of the thigh openings of the underwear. At this time, there are at least the following two distribution modes of the elastic sewing area 4.

[0036] One is that the crotch is surrounded by elastic sewing areas 4, that is, the elastic deformation capacity of the first bottom crotch piece 1 and the second bottom crotch piece 2 is greater than that of the activated carbon fiber sheet 3. Therefore, during the sewing process, it is necessary to ensure that all elastic sewing areas 4 and activated carbon fiber sheets 3 have a certain distance.

[0037] Secondly, the area in the crotch connected to the front piece 7 or the back piece 8 is a non-elastic sewn area 4, while the sewn area at the edge of the thigh opening is an elastic sewn area 4, that is, when the ability to adjust the size of the thigh opening is better, it is only necessary to ensure that there is a certain distance between the sewn area at the edge of the thigh opening and the activated carbon fiber sheet 3.

[0038] If the edge of the activated carbon fiber sheet 3 is too close to the elastic sewing area 4, when the first bottom crotch sheet 1 and the second bottom crotch sheet 2 are lock-stitched or the activated carbon fiber sheet 3 is fixed, the elastic sewing area 4 and the activated carbon fiber sheet 3 may be involved in the flattening process of the fabric at the same time. Therefore, this embodiment limits the existence of a gap between the elastic sewing area 4 and the activated carbon fiber sheet 3, avoiding the wrinkle problem caused by the simultaneous participation of the two in the flattening and sewing process.

[0039] In order to increase the deformation performance of the crotch thigh opening and improve its adaptability to the wearer's leg shape, an improvement is made on the basis of Example 2, and an elastic band can be provided between the first bottom crotch piece 1 and the second bottom crotch piece 2 in the elastic sewing area 4.

[0040] In a specific implementation, the crotch structure often requires a certain degree of elasticity in the area serving as the edge of the thigh opening, so an elastic band is usually provided. However, the provision of the elastic band increases the difference in elastic deformation capacity between the activated carbon fiber sheet 3 and the upper and lower crotch sheets. During the hemming, if the elastic fiber sheet is flattened and sewn together with the crotch sheet or is too close to the sewing area of ​​the two crotch sheets, wrinkles may form during the contraction of the fabric after the hemming is completed due to the elastic difference. Therefore, when an elastic band is provided, the sewing process provided by the present invention can further avoid the formation of wrinkles and increase wearing comfort.

[0041] Example 3: In order to reduce the occurrence of powdering or fine fiber dropping of the activated carbon fiber sheet 3, an improvement was made based on Example 1, such as Figure 2 As shown, in this embodiment, the four sides of the activated carbon fiber sheet 3 are connected to the first bottom crotch sheet 1 and / or the second bottom crotch sheet 2 through a first sewing line 5, the edge of the activated carbon fiber sheet 3 is exposed at the first sewing line 5 and is located between the first bottom crotch sheet 1 and the second bottom crotch sheet 2, the first bottom crotch sheet 1 and the second bottom crotch sheet 2 are connected by a second sewing line 6, and the edge of the activated carbon fiber sheet 3 is accommodated in the area between the first sewing line 5 and the second sewing line 6.

[0042] In the specific implementation process, in the process of fixing the activated carbon fiber sheet 3, stitching can be performed along its edge to form a first stitching line 5. Figure 2As shown, outside the rectangular area formed by the first sewing line 5, there will always be a certain width of the activated carbon fiber sheet 3 exposed in the rectangular area. During the wearer's exercise or the washing of the activated carbon crotch, the relative displacement between the activated carbon fiber sheet 3 exposed in the rectangular area and the upper and lower layers of the bottom crotch is large. In the process of continuous mutual friction, the activated carbon fiber sheet 3 will be aggravated to lose powder or drop fine fibers. Therefore, after the first bottom crotch sheet 1 and the second bottom crotch sheet 2 are sewn together by the second sewing line 6 in this embodiment, the activated carbon fiber sheet 3 exposed in the rectangular area is accommodated in the area between the first sewing line 5 and the second sewing line 6, thereby reducing the range of relative displacement between the activated carbon fiber sheet 3, the first bottom crotch sheet 1 and the second bottom crotch sheet 2.

[0043] In order to further reduce the occurrence of powder loss or falling of fine fibers of the activated carbon fiber sheet 3, the distance between the first sewing line 5 and the second sewing line 6 is set to D1, the edge width of the activated carbon fiber sheet 3 exposed at the first sewing line 5 is D2, and D1-D2≤2mm.

[0044] In practice, the closer the distance between the first and second stitching lines 5, 6, is to the width of the edge of the activated carbon fiber sheet 3 exposed within the rectangular area formed by the first stitching line 5, the tighter the first and second crotch panels 1, 2, and the better the fixation between the activated carbon fiber sheet 3 and the upper and lower crotch panels. Friction between the activated carbon fiber sheet 3 and the crotch panels is also reduced, minimizing the risk of powder or fine fiber shedding. Experiments have shown that a difference between D1 and D2 of less than or equal to 2 mm is optimal.

[0045] In order to reduce the sewing process, such as Figure 2 As shown, in this embodiment, the second sewing lines 6 are provided on both sides of the activated carbon fiber sheet 3 in the width direction.

[0046] In a specific implementation, if the four ends of the activated carbon fiber sheet 3 are at a certain distance from the sewing areas of the two bottom crotch sheets, the second sewing lines 6 can be set around the activated carbon fiber sheet 3 in the same manner as the first sewing lines 5. However, in the process of sewing the two-layer bottom crotch sheet, only the edge at the thigh opening is the elastic sewing area 4, while the sewing area at the end connected to the front sheet 7 or the back sheet 8 is the non-elastic sewing area 4. In order to ensure the area of ​​the internal functional layer and improve its use effect, the following method can be used: Figure 2As shown, the upper and lower ends of the activated carbon fiber sheet 3 are arranged close to the edge of the bottom crotch sheet. Since the elastic deformation ability of the upper and lower ends of the bottom crotch sheet is slightly different from that of the activated carbon fiber sheet 3, even if they are arranged close to each other, wrinkles will not be generated after the lock-stitching. At the same time, the edge of the activated carbon fiber sheet 3 exposed in the rectangular area formed by the first sewing line 5 is close to the step area formed after the lock-stitching of the bottom crotch sheet. Under the restrictions of the step area, the first sewing line 5 and the second sewing lines 6 on both sides in the width direction, the range of relative displacement between the upper and lower layers of the bottom crotch sheet is small. Therefore, the second sewing line 6 can be set only on the left and right sides of the activated carbon fiber sheet 3 to simplify the sewing process.

[0047] Example 4: In order to improve the aesthetics of the activated carbon crotch, improvements were made based on Example 1. The activated carbon fiber sheet 32 ​​was connected to the first bottom crotch sheet 1 through a first sewing line 5, and the second bottom crotch sheet 2 was connected to the first bottom crotch sheet 1 by lock-stitching.

[0048] In a specific implementation, the second bottom crotch sheet 2 can be used as the outer layer of the activated carbon crotch, and a waterproof layer 31 is provided between the outer layer and the activated carbon fiber sheet 32. If the activated carbon fiber sheet 32 ​​is sewn to the outer layer, the waterproof layer 31 may be punctured, thereby reducing the waterproof performance of the waterproof layer 31. At the same time, only the activated carbon fiber sheet 32 ​​is sewn to the first bottom crotch sheet 1, so that there is no sewing line on the outer layer of the crotch, which improves the appearance of the pants.

[0049] Example 5: In order to improve the performance of the activated carbon crotch pants, improvements were made on the basis of Examples 1-4, such as Figure 3 As shown, in this embodiment, one or more of a waterproof layer 31 or a dustproof and breathable layer 33 is further provided between the first bottom crotch piece 1 and / or the second bottom crotch piece 2 and the activated carbon fiber sheet 32. Any one of the first bottom crotch piece 1 or the second bottom crotch piece 2 serves as the outer layer of the crotch, and the waterproof layer 31 is arranged close to the outer layer.

[0050] In the specific implementation process, the connection method of the waterproof layer 31 or the dustproof and breathable layer 33 is not limited. It can be connected to the surface of the activated carbon fiber sheet 32, or connected to the bottom crotch sheet, or even directly accommodated between the activated carbon fiber sheet 32 ​​and the bottom crotch sheet. The arrangement of the waterproof layer 31 or the dustproof and breathable layer 33 can refer to the following embodiments:

[0051] Embodiment 1: The activated carbon fiber sheet 32 ​​is located between the waterproof layer 31 and the dustproof and breathable layer 33, and either the first bottom crotch sheet 1 or the second bottom crotch sheet 2 serves as the outer layer of the crotch, and the waterproof layer 31 is arranged close to the outer layer.

[0052] During the specific implementation process, the first bottom crotch piece 1 can be used as the surface contact layer, and the second bottom crotch piece 2 can be used as the outer layer. The hierarchical structure of the crotch can be outer layer - waterproof layer 31 - activated carbon fiber sheet 32 ​​- dustproof and breathable layer 33 - surface contact layer. Among them, the outer layer can be made of pure cotton material or wear-resistant material, and it and the surface contact layer are locked or sewn to form a cavity for placing the activated carbon fiber sheet 32. The waterproof layer 31 - activated carbon fiber sheet 32 ​​- dustproof and breathable layer 33 constitute the internal functional layer. Since the activated carbon fiber is prone to powdering or fine fibers, the dustproof and breathable layer 33 is set on the upper part of the activated carbon fiber sheet 32 ​​to prevent the activated carbon fiber from falling out and ensure its water absorption effect. In order to prevent the water in the activated carbon fiber after absorbing water from penetrating into the outer layer and affecting the wearer's use, the waterproof layer 31 is set to ensure that the absorbed water does not penetrate into the outer layer; the waterproof layer 31 can be made of PTFE membrane, and the dustproof and breathable layer 33 can be made of polyester fiber. The surface contact layer mainly contacts the crotch, and can be made of clean, hygienic and absorbent materials, such as pure cotton. At the same time, materials with antibacterial, deodorizing and repairing functions can be considered.

[0053] Embodiment 2: Either the first bottom crotch sheet 1 or the second bottom crotch sheet 2 serves as the outer layer of the crotch, and a first dustproof and breathable layer 33 and a waterproof layer 31 are provided between the outer layer and the activated carbon fiber sheet 32. The waterproof layer 31 is provided close to the outer layer, and a second dustproof and breathable layer 33 is provided on the side of the activated carbon fiber sheet 32 ​​away from the waterproof layer 31.

[0054] In a specific implementation, the dustproof layer is provided on both sides of the activated carbon fiber sheet 32 ​​to further reduce the occurrence of powder or fine fibers falling from the activated carbon fiber sheet 32. The waterproof layer 31 can prevent the water in the activated carbon fiber after absorbing water from penetrating into the outer layer and affecting the wearer's use.

[0055] Example 6: An activated carbon underwear, comprising: the activated carbon crotch, wherein the first bottom crotch piece 1 or the second bottom crotch piece 2 in the activated carbon crotch is a part of the underwear body.

[0056] In the specific implementation process, the underwear body refers to the shape of Figure 4 As shown, the main structure of the waist opening and leg openings has been formed. There are many ways to implement the underwear body during the sewing process, and the specific ones can be referred to as follows:

[0057] Embodiment 1: The main body of the underwear is obtained by connecting multiple pieces. The number of pieces is not limited and can be two-piece or three-piece, etc. For example, the first bottom crotch piece, the front piece 7 and the back piece 8 are sewn together to form the main body of the underwear; there is a gap between the connection area between the front piece 7 or the back piece 8 and the first bottom crotch piece 1 and the end of the first bottom crotch piece 1, and the piece between the end of the first bottom crotch piece 1 and the connection area is the residual edge 9 of the first bottom crotch piece, and the residual edge 9 is located in the inner layer of the main body of the underwear; the second bottom crotch piece 2 is sewn together with the residual edge 9 at one end close to the front piece 7 or the back piece 8.

[0058] In practice, conventional underwear structures primarily consist of a front panel 7, a back panel 8, a waistband, a crotch, and elastic edges (such as the leg openings and waist). The front panel 7 covers the front area of ​​the wearer and is typically relatively flat to accommodate the physiological structure of men or women. The back panel 8 covers the back area of ​​the wearer. For men's underwear, the back panel 8 may be designed with specialized pouches to provide better support and comfort; women's underwear focuses more on fitting the body shape. The crotch is the connecting portion between the front panel 7 and the back panel 8. The design must consider the wearer's freedom of movement to avoid a sense of restraint. For men's underwear, the crotch design is particularly important, ensuring sufficient space to accommodate the genitals. The edges on both sides of the underwear near the base of the thighs are also typically made of elastic material to ensure that the underwear fits tightly against the legs and does not slip. The waistband is also designed with elasticity to enhance stability and comfort, such as using rubber bands or spandex.

[0059] If the first bottom crotch piece 1 and the second bottom crotch piece 2 are sewn together and then connected to the front piece 7 or the back piece 8, a step area consisting of three layers of fabric formed by the two bottom crotch pieces and the front piece 7 or the back piece 8 will be formed, which will have a strong foreign body sensation. Therefore, this embodiment provides a residual edge 9, which is sewn together with the second bottom crotch piece 1 to form a two-layer step area with a certain degree of mobility, thereby increasing the wearing comfort of the underwear.

[0060] exemplary, reference Figure 1-2 and Figure 4-5 As shown, first cut the cloth and activated carbon fiber sheet 3 according to the underwear sample, sew the first bottom crotch piece 1, the front piece 7 and the back piece 8 into the shape Figure 4 The underwear body of the structure shown in FIG. Figure 5As shown, the edge of the first bottom crotch piece 1 is not completely sewn and fixed with the front piece 7 or the back piece 8, but a residual margin 9 is left, and the left and right sides of the front piece 7 and the back piece 8 are not yet connected. A four-thread overlocking machine is used to sew the residual margin 9 of the first bottom crotch piece 1 to the upper and lower ends of the second bottom crotch piece 2, and then the left edge or right edge of the first bottom crotch piece 1 and the second bottom crotch piece 2 are sewn together. Then, the cut activated carbon fiber sheet 3 is placed between the locked two layers of bottom crotch. Then, a sewing machine is used to pierce the first stitching line 5 to fix the activated carbon fiber sheet 3 around, and then a second stitching line 6 is sewn at intervals of 1 cm around the activated carbon. Finally, the left and right sides of the front piece 7 and the back piece 8 are sewn together to form a waist opening and leg openings, and the non-sewn sides of the first bottom crotch piece 1 and the second bottom crotch piece 2 are sewn together. Elastic is added to the waist opening and leg openings and locked.

[0061] Embodiment 2: The underwear main body is a one-piece piece, which includes a first bottom crotch piece 1 or a second bottom crotch piece 2 structure. The first bottom crotch piece 1 or the second bottom crotch piece 2 on the underwear main body is sewn and connected to the activated carbon fiber sheet 32, and the other bottom crotch piece is connected to the underwear main body.

[0062] During implementation, the activated carbon fiber sheet 32 ​​can be first connected to the crotch sheet of the underwear body. In this way, the other crotch sheet, which serves as the outer layer of the underwear, can be connected only to the crotch sheet of the underwear body. Since there is no sewing line between the outer layer and the activated carbon fiber sheet 32, the waterproof layer 31 between the outer layer and the activated carbon fiber sheet 32 ​​will not be punctured, thereby improving the waterproof effect of the waterproof layer 31. In addition, the outer layer of the underwear has no exposed sewing line, which improves the appearance.

[0063] Example 7: In order to improve the fit between the thigh opening of the underwear and the wearer, improvements are made based on Example 6, such as Figure 4 As shown, a pair of underwear made by the sewing process, the first bottom crotch piece 1 and the second bottom crotch piece 2 both include a first connecting end 11, a second connecting end 12, a first deforming end 13 and a second deforming end 14, the first connecting end 11 is opposite to the second connecting end 12, the first deforming end 13 is opposite to the second deforming end 14, and the first deforming end 13 and the second deforming end 14 are both arc-shaped.

[0064] In the specific implementation process, the first deformation end 13 and the second deformation end 14 are the leg openings of the underwear, which are arc-shaped and more easily match the shape of the thigh. The shapes of the first connection end 11 and the second connection end 12 are not limited and can be straight lines or as shown in FIG. Figure 2 The arc-shaped structure has a smaller curvature, and the first connecting end 11 and the second connecting end 12 are used to connect the front panel 7 and the back panel 8.

[0065] Example 8: In order to further reduce the occurrence of powdering or fine fiber dropping of the activated carbon fiber sheet 3, an improvement was made based on Example 7, such as Figure 2As shown, the first deformation end 13 and the second deformation end 14 of the crotch are provided with elastic bands, the activated carbon fiber sheet 3 is rectangular, the distance between the edge of the activated carbon fiber sheet 3 and the first deformation end 13 or the second deformation end 14 is at least greater than or equal to 1 cm, and the distance between the two ends of the length direction of the activated carbon fiber sheet 3 and the first connecting end 11 or the second connecting end 12 is less than 1 cm.

[0066] During the specific implementation process, this embodiment sets the distance between the edge of the activated carbon fiber sheet 3 and the first deformation end 13 or the second deformation end 14 according to the actual flattening of the fabric during sewing, which can avoid the activated carbon fiber sheet 3 participating in the process of flattening the fabric when locking the deformed end of the first bottom crotch sheet 1 and the deformed end of the second bottom crotch sheet 2, resulting in wrinkles after locking.

[0067] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
