[0029] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0030] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0032] The embodiment of the utility model provides a fabric that is universal on both sides, such as Figure 1 and Figure 2 As shown, it includes a fabric body 200 and an elastic band 100. According to different clothing requirements, the fabric body 200 can be woven from corresponding yarns. The elastic band 100 can be a visible rib elastic band or other types of elastic bands. The elastic band 100 includes two bifurcated bands 120. The two bifurcated bands 120 extend along the length direction of the fabric body 200. The upper ends of the two bifurcated bands 120 are connected. Since the elastic band is a flexible structure, the lower ends of the two bifurcated bands 120 can be opened in a direction away from each other. The fabric body 200 is inserted between the two bifurcated bands 120, and the two bifurcated bands 120 are fixed on the front and back sides of the fabric body 200 respectively.

[0033] In this embodiment, the structure and appearance of the front and back of the entire fabric are almost the same. When using, the user does not need to distinguish the front and back of the fabric. The front and back of the fabric can be used outward, which improves the convenience of use. At the same time, the elastic band 100 can wrap the edge of the fabric body 200 to prevent the thread from rubbing against the skin, which also improves the comfort of wearing.

[0034] The two bifurcated belts 120 of this embodiment are woven into one piece. Figure 2 For example, it is equivalent to folding the existing elastic band along the folding center line, and then forming two bifurcated bands 120. The integral braiding can simplify the overall manufacturing process and enhance the connection strength of the two bifurcated bands 120. Of course, the two bifurcated bands 120 can also be fixedly connected by gluing, sewing or other methods.

[0035] In some embodiments, the two bifurcated belts 120 are respectively pasted and fixed on the front and back sides of the fabric body 200. The pasting and fixing method is easy to operate and can simplify the process. The glue is located on the contact surface between the fabric body 200 and the bifurcated belt 120, which will not affect the appearance of the bifurcated belt 120 and can also easily keep the bifurcated belt 120 flat.

[0036] In one embodiment, the two bifurcated belts 120 are respectively fixed to the front and back of the fabric body 200 by a mixture of TPU hot melt adhesive and PA glue. The adhesive formed by the mixture of TPU hot melt adhesive and PA glue has a greater bonding strength, which can improve the peeling degree and enhance the connection strength between the two bifurcated belts 120 and the fabric body 200. The ratio of TPU hot melt adhesive and PA glue can be determined according to actual needs. For example, the mass ratio of TPU hot melt adhesive and PA glue can be 1:1.

[0037] In another embodiment, the inner side of the two bifurcated belts 120 is first coated with an adhesive layer 310, and then a plurality of adhesive dots 320 are formed on the adhesive layer 310 by dotting, and finally the inner side of the two bifurcated belts 120 are respectively adhered and fixed to the front and back of the fabric body 200. Compared with the traditional single-layer adhesive bonding, the firmness of the double-layer adhesive bonding is further improved. The peeling degree of the single-layer adhesive bonding is generally 0.9-1.0 kg per square centimeter, and the peeling degree of the double-layer adhesive bonding in this embodiment can reach 1.8 kg per square centimeter. In addition, the two bifurcated belts 120 are both double-layer adhesive, which can greatly improve the peeling degree and enhance the connection strength between the two bifurcated belts 120 and the fabric body 200.

[0038] The adhesive layer 310 may be made of TPU hot melt adhesive, and the adhesive point 320 may be made of PA glue. Of course, the adhesive layer 310 and the adhesive point 320 may also be made of other adhesives according to actual needs.

[0039] In other embodiments, the two bifurcated belts 120 may also be fixed to the front and back sides of the fabric body 200 respectively by sewing or other means.

[0040] The embodiment of the utility model also provides a pair of underwear with both front and back sides being compatible, such as Figure 3 As shown, the pant body 400 includes a pant body 400 and an elastic waistband 101, and the pant body 400 is made of a whole piece of fabric, so that the front and back sides of the pant body 400 have basically the same structure and appearance, which creates conditions for the front and back sides of the entire pant to be universal. According to different actual needs, the pant body 400 can be made of different fabrics.

[0041] The elastic waistband 101 can be a visible elastic band or other types of elastic bands, which are adapted to the shape of the waist position of the trouser body 400 and are in an annular structure. The elastic waistband 101 includes two bifurcated belts 120, both of which are arranged in an annular shape, and one of the bifurcated belts 120 is located inside the other bifurcated belt 120, and the upper ends of the two bifurcated belts 120 are connected. Since the elastic waistband 101 is a flexible structure, the lower ends of the two bifurcated belts 120 can be opened in a direction away from each other. The waist of the trouser body 400 is inserted between the two bifurcated belts 120, and the two bifurcated belts 120 are fixed to the front and back of the trouser body 400 respectively.

[0042] In this embodiment, the structure and appearance of the front and back sides of the entire underwear are almost the same. When using the underwear, the user does not need to distinguish between the front and back sides. The underwear can be worn with the front side facing outward or the back side facing outward, which improves the convenience of wearing. At the same time, the elastic waistband 101 can wrap the edge of the trouser body 400 inside to prevent the thread ends from rubbing against the skin, which also improves the comfort of wearing.

[0043] The two bifurcated belts 120 of this embodiment are integrally woven, which is equivalent to folding the existing elastic belt along the folding center line to form two bifurcated belts 120. Integral woven molding can simplify the overall manufacturing process and enhance the connection strength of the two bifurcated belts 120. Of course, the two bifurcated belts 120 can also be fixedly connected by gluing, sewing or other methods.

[0044] In some embodiments, two thickened layers 410 are fixed on the front and back of the crotch position of the trouser body 400, and the two thickened layers 410 on the front of the crotch position of the trouser body 400 and the two thickened layers on the back of the crotch position of the trouser body 400 are symmetrically arranged relative to the center line of the trouser body 400. The presence of the thickened layer 410 can increase the thickness of the crotch position, and provide better protection for the user's crotch. At the same time, since the thickened layer 410 is fixed on the front and back of the crotch position of the trouser body 400, it is ensured that the structure and appearance of the front and back of the entire underwear are almost the same, and the underwear can still be worn forward or backward.

[0045] Furthermore, the two thickened layers 410 are sewn together with each other and with the trouser body 400 by hidden threads. The bottom crotch 430 of the trouser body 400 is sewn with four needles and six threads on both sides. The sewing threads are hidden, so that the appearance of the entire underwear has no exposed thread ends, which improves the wearing comfort and the appearance.

[0046] In some embodiments, the elastic waistband 101 includes an elastic band 100 and a shaping layer. The elastic band 100 is bent into a ring shape, and its ends are connected by ultrasonic technology, and the connecting position is sewn together with thread to enhance the connection strength. The shaping layer covers the front and back sides of the connecting position, and the shaping layer is adhered and fixed to the front and back sides of the elastic band 100. The shaping layer hides the connecting position, so that the connecting position is not easy to break, further improving the stability of the connection, and at the same time, improving the appearance.

[0047] In this embodiment, the shaping layer can be folded in the middle, and the elastic band 100 is inserted into the folded two-layer structure of the shaping layer from below, and the folded two-layer structure is respectively adhered and fixed to the front and back sides of the elastic band 100. This does not affect the two bifurcated bands 120 from opening in the direction away from each other.

[0048] In some embodiments, the two fork straps 120 are respectively glued and fixed to the front and back sides of the trouser body 400. The gluing and fixing method is easy to operate and can simplify the process. The glue is located on the contact surface between the trouser body 400 and the fork strap 120, which will not affect the appearance of the fork strap 120 and can also easily keep the fork strap 120 flat.

[0049] In one embodiment, the two bifurcated straps 120 are respectively attached to the front and back of the trouser body 400 by a mixture of TPU hot melt adhesive and PA glue. The adhesive formed by the mixture of TPU hot melt adhesive and PA glue has a greater bonding strength, which can improve the peeling degree and enhance the connection strength between the two bifurcated straps 120 and the trouser body 400. The ratio of TPU hot melt adhesive and PA glue can be determined according to actual needs. For example, the mass ratio of TPU hot melt adhesive and PA glue can be 1:1.

[0050] In another embodiment, the inner side of the two bifurcated belts 120 is first coated with an adhesive layer, and then a plurality of adhesive dots are formed on the adhesive layer by dotting, and finally the inner side of the two bifurcated belts 120 are respectively adhered and fixed to the front and back of the trouser body 400. Compared with the traditional single-layer adhesive bonding, the firmness of the double-layer adhesive bonding is further improved. The peeling degree of the single-layer adhesive bonding is generally 0.9-1.0 kg per square centimeter, and the peeling degree of the double-layer adhesive bonding in this embodiment can reach 1.8 kg per square centimeter. In addition, the two bifurcated belts 120 are both double-layer adhesive, which can greatly improve the peeling degree and enhance the connection strength between the two bifurcated belts 120 and the trouser body 400.

[0051] The adhesive layer can be made of TPU hot melt adhesive, and the dispensing can be made of PA glue. Of course, according to actual needs, the adhesive layer and the dispensing can also be made of other adhesives.

[0052] In other embodiments, the two bifurcated belts 120 may also be fixed to the front and back of the trouser body 400 respectively by sewing or other means.

[0053] The embodiment of the utility model provides a fabric that is universal on both sides, such as Figure 4 and Figure 5 As shown, it includes a fabric body 200 and an elastic band 100. According to different clothing needs, the fabric body 200 can be woven from corresponding yarns. The elastic band 100 can be a visible elastic band or other types of elastic bands. The elastic band 100 includes a main body 110 and two bifurcated bands 120. The extension direction of the bifurcated bands 120 is the same as the extension direction of the main body 110, and both extend along the length direction of the fabric body 200. The two bifurcated bands 120 are both arranged below the main body 110 and are connected to the main body 110. Since the elastic band is a flexible structure, the two bifurcated bands 120 can be opened in a direction away from each other. The fabric body 200 is inserted between the two bifurcated bands 120, and the two bifurcated bands 120 are respectively fixed on the front and back sides of the fabric body 200.

[0054] In this embodiment, the structure and appearance of the front and back of the entire fabric are almost the same. When using, the user does not need to distinguish the front and back of the fabric. The front and back of the fabric can be used outward, which improves the convenience of use. At the same time, the elastic band 100 can wrap the edge of the fabric body 200 to prevent the thread from rubbing against the skin, which also improves the comfort of wearing.

[0055] The two bifurcated belts 120 of this embodiment can be integrally woven with the main body 110, which is equivalent to disassembling a part of the existing elastic belt into two bifurcated belts. The integrally woven belt can simplify the overall manufacturing process and enhance the connection strength between the bifurcated belt 120 and the main body 110. Of course, the two bifurcated belts 120 can also be fixedly connected to the main body 110 by gluing, sewing or other methods.

[0056] In some embodiments, the two bifurcated belts 120 are respectively pasted and fixed on the front and back sides of the fabric body 200. The pasting and fixing method is easy to operate and can simplify the process. The glue is located on the contact surface between the fabric body 200 and the bifurcated belt 120, which will not affect the appearance of the bifurcated belt 120 and can also easily keep the bifurcated belt 120 flat.
