Description

Technical Field

[0001] This utility model relates to the field of underband technology, and in particular to a seamless heat-applied underband. Background Technology

[0002] Currently, underbands (or waistbands) are generally made into elastic bands for underwear. The underbands that are purchased are all loop-shaped. They are purchased in bulk and then cut and processed into finished products of different sizes. The traditional processing method is to first cut the underband and then sew the two ends together with needle and thread. However, the connection strength of the needle and thread is not good enough. During normal use, the underband will be stretched. When the underband is stretched, the needle and thread at the connection of the two ends of the underband is prone to breakage. Moreover, the stitching is not aesthetically pleasing and will cause discomfort when it is in contact with the skin. Poorly handled thread ends make it look cheap, resulting in poor product quality. Utility Model Content

[0003] This utility model aims to solve the technical problems existing in the prior art. To this end, this utility model proposes a seamless heat-pressed underband, which replaces the traditional needle and thread sewing method by heat-pressing a first connecting fabric and a second connecting fabric at the connection positions at both ends. This not only enhances the connection stability but also improves product quality, and the fit is more aesthetically pleasing and more comfortable to the skin.

[0004] The seamless heat-pressed underband according to a first aspect embodiment of the present invention includes:

[0005] The annular shroud body is formed into a first end and a second end by ultrasonic cutting, and the first end and the second end are bonded together.

[0006] A first connecting fabric is bonded to the connection between the first end and the second end, and the elastic modulus of the first connecting fabric is less than the elastic modulus of the annular shroud body.

[0007] The second connecting fabric is bonded to the surface of the first connecting fabric away from the annular band body. Along the length direction of the annular band body, the length of the second connecting fabric is greater than the length of the first connecting fabric, and the second connecting fabric covers the sides of the first connecting fabric along the length direction of the annular band body. The elastic modulus of the second connecting fabric is greater than that of the first connecting fabric.

[0008] The seamless heat-sealed underband according to the embodiments of this utility model has at least the following beneficial effects: the annular underband body is cut into two ends by ultrasonic cutting process. Since the underband melts when heated, its two ends can be directly bonded together. A first connecting cloth is used to bond the first end and the second end of the annular underband body. The elastic modulus of the first connecting cloth is less than that of the annular underband body. When the annular underband body is pulled, the first connecting cloth will not undergo large deformation along with the annular underband body, thereby playing a role in preventing pulling at the connection position. In this way, the first connecting cloth can improve the connection at the connection position of the first end and the second end. Connection strength; the second connecting fabric covers the sides of the first connecting fabric along the length of the annular band body. Since the elastic modulus of the second connecting fabric is greater than that of the first connecting fabric, when the annular band body is pulled, the second connecting fabric will deform more along with the annular band body. In this way, it can cover up the discomfort caused to the user by the first connecting fabric, and the second connecting fabric can also improve the connection strength. It can be understood as playing a double protection role, which can ensure the stable connection between the first end and the second end of the annular band body, thereby improving the quality of the product. Moreover, the fit is more aesthetically pleasing and has a higher comfort level when in contact with the skin.

[0009] According to some embodiments of the present invention, the width of the first connecting fabric is smaller than the width of the annular webbing body, and there is a gap between the side of the first connecting fabric and the side of the annular webbing body along the width direction of the annular webbing body.

[0010] According to some embodiments of the present invention, the width of the second connecting fabric is smaller than the width of the annular webbing body. Along the width direction of the annular webbing body, there is a gap between one side of the second connecting fabric and one side of the annular webbing body, and the other side of the second connecting fabric is attached to the other side of the annular webbing body.

[0011] According to some embodiments of the present invention, along the width direction of the annular circumferential band body, the width of the first connecting cloth is smaller than the width of the second connecting cloth, and there is a gap between the side edge of the first connecting cloth and the side edge of the second connecting cloth.

[0012] According to some embodiments of the present invention, the seamless heat-pressed underband further includes an identification layer, which is located on the surface of the second connecting fabric opposite to the first connecting fabric.

[0013] According to some embodiments of the present invention, the marking layer is attached to the surface of the second connecting fabric by hot pressing.

[0014] According to some embodiments of the present invention, the first connecting cloth is rectangular.

[0015] According to some embodiments of this utility model, the second connecting fabric is rectangular or square.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0028] Reference Figure 1 and Figure 5 As shown, a seamless heat-pressed underband 1000 provided in this embodiment of the present invention includes an annular underband body 100, a first connecting fabric 200, and a second connecting fabric 300. The seamless heat-pressed underband 1000 is generally made into an elastic band for underwear.

[0029] Specifically, the annular shroud body 100 is first cut into a first end 110 and a second end 120 using an ultrasonic cutting process. Since the lower shroud melts upon heating, the first end 110 and the second end 120 can be directly bonded together. (Refer to...) Figure 1 As shown, the annular band body 100 has a length direction and a width direction. The annular band body 100 is made of elastic material, which allows the annular band body 100 to undergo greater deformation, thereby improving wearing comfort.

[0030] Reference Figure 2 As shown, the first connecting fabric 200 is rectangular and is bonded to the connection between the first end 110 and the second end 120. An adhesive layer exists between the first connecting fabric 200 and the annular webbing body 100. The first connecting fabric 200 is bonded to the surface of the annular webbing body 100 by heat pressing. The elastic modulus of the first connecting fabric 200 is less than that of the annular webbing body 100. The first connecting fabric 200 can be made of nylon woven fabric or non-woven fabric. This design prevents the first connecting fabric 200 from undergoing significant deformation along with the annular webbing body 100 when it is pulled. The lower elasticity of the first connecting fabric 200 reduces the shear force on the adhesive layer between it and the annular webbing body 100, thus stabilizing the adhesive layer and improving the connection strength at the connection between the first end 110 and the second end 120.

[0031] Reference Figure 3As shown, the second connecting fabric 300 can be square or rectangular. The second connecting fabric 300 is bonded to the surface of the first connecting fabric 200 facing away from the annular webbing body 100. An adhesive layer exists between the second connecting fabric 300 and the annular webbing body 100 (this adhesive layer extends between the second connecting fabric 300 and the first connecting fabric 200). The elastic modulus of the second connecting fabric 300 is greater than that of the first connecting fabric 200 (the elastic modulus of the second connecting fabric 300 can be close to that of the annular webbing body 100, i.e., their elongation lengths are similar). The second connecting fabric 300 can be made of open-knit fabric or elastic band, and its material can be the same as that of the annular webbing body 100. During the bonding process, an adhesive layer is first applied to one side of the first connecting fabric 200, and then to the other side of the second connecting fabric 300. After the first connecting fabric 200 is bonded, the second connecting fabric 300 is bonded. Along the length direction of the annular webbing body 100, the length of the second connecting cloth 300 is greater than the length of the first connecting cloth 200, and the second connecting cloth 300 covers the sides of the annular webbing body 100 on both sides along the length direction. This design allows the second connecting fabric 300 to deform significantly along with the annular band body 100 when the annular band body 100 is pulled. This can mask the discomfort caused to the user by the first connecting fabric 200 (because the first connecting fabric 200 has a lower deformation capacity and is closer to the user's skin, making it feel harder). Furthermore, the second connecting fabric 300 can improve the connection strength at the connection point. The adhesive layer between the second connecting fabric 300 and the annular band body 100 can cover (or seal) the sides of the first connecting fabric 200, preventing the adhesive layer between the first connecting fabric 200 and the annular band body 100 from cracking. This can be understood as providing double protection, ensuring a more stable connection between the first end 110 and the second end 120 of the annular band body 100, thereby improving product quality.

[0032] It should be noted that, in the above embodiments, the elastic modulus can specifically be any one of Young's modulus, shear modulus, or bulk modulus. Young's modulus is generally used to evaluate the elastic modulus of a material.

[0033] Reference Figure 2As shown, in some embodiments, the width of the first connecting fabric 200 is smaller than the width of the annular webbing body 100. Along the width direction of the annular webbing body 100, there is a gap between the third side 210 of the first connecting fabric 200 and the first side 130 of the annular webbing body 100, and there is also a gap between the fourth side 220 of the first connecting fabric 200 and the second side 140 of the annular webbing body 100. This arrangement facilitates subsequent hemming operations in the spaces between the first side 130 and the third side 210, and between the second side 140 and the fourth side 220.

[0034] Reference Figure 3 As shown, in some embodiments, the width of the second connecting fabric 300 is smaller than the width of the annular webbing body 100. Along the width direction of the annular webbing body 100, the fifth side 310 of the second connecting fabric 300 is attached to the first side 130 of the annular webbing body 100, and there is a gap between the sixth side 320 of the second connecting fabric 300 and the second side 140 of the annular webbing body 100. This arrangement facilitates subsequent hemming operations in the space between the second side 140 and the sixth side 320.

[0035] Reference Figure 3 As shown, in some embodiments, along the width direction of the annular band body 100, the width of the first connecting fabric 200 is smaller than the width of the second connecting fabric 300, and there is a gap between the third side 210 and the fifth side 310, and a gap between the fourth side 220 and the sixth side 320. This allows the second connecting fabric 300 to cover the third side 210 and the fourth side 220 of the first connecting fabric 200. This arrangement can seal and fix the sides of the first connecting fabric 200, and the second connecting fabric 300 completely covers the first connecting fabric 200, so that the first connecting fabric 200 will not directly contact the user's skin. Since the second connecting fabric 300 is more elastic, the second connecting fabric 300 provides better comfort when it directly contacts the user's skin.

[0036] In some embodiments, the seamless heat-pressed lower band 1000 further includes an identification layer, which can be used to identify product logos, sizes, or production numbers, etc. The identification layer is located on the surface of the second connecting fabric 300 opposite to the first connecting fabric 200. The identification layer can be attached to the surface of the second connecting fabric 300 by means of adhesive or heat pressing. In conventional solutions, the identification layer is placed on the surface of the annular band body 100. In this embodiment, the identification layer is placed on the second connecting fabric 300 beforehand. When the identification layer is processed by heat pressing, since the heat pressing process of the second connecting fabric 300 also requires heating the adhesive layer, the adhesive layer of the second connecting fabric 300 can be preheated after the identification layer is heat-pressed, which facilitates the subsequent process of heat pressing the second connecting fabric 300 onto the first connecting fabric 200. This eliminates the need for an additional process of processing the identification layer on the annular band body 100.
