[0002] At present, in the field of textiles and clothing, the waist of sports pants and casual pants usually needs to be controlled with drawstrings or elastic bands to control the tightness. The traditional methods of using drawstrings or elastic bands to control the tightness of the waist are: 1. Wearing a drawstring directly on the waist of non-elastic pants will cause wrinkles on the waist of the pants, which will obviously affect the appearance and comfort, and there is a risk of the drawstring loosening; 2. Only elastic elastic bands without drawstrings are prone to aging and loss of elasticity, which will affect the service life of the pants; 3. There are both elastic bands and drawstrings, and the elastic bands and drawstrings cannot be fixed uniformly. The space in the middle of the elastic band is too large, which causes the drawstring to twist, and increases the cost of sewing. Summary of the invention

[0003] Based on this, it is necessary to provide an elastic tunnel webbing to address the problems of the traditional method of controlling the tightness of the waistband, such as causing wrinkles on the waistband that significantly affect the appearance and comfort, and there is a risk of the drawstring loosening, the elastic band is prone to aging and losing elasticity, which affects the service life of the pants, the elastic band and the drawstring cannot be fixed uniformly, and the elastic band has too much space in the middle that causes the drawstring to twist, which increases the sewing cost.

The elastic tunnel webbing will be described below with reference to the accompanying drawings.

[0042] The elastic tunnel webbing provided in the embodiment of the present application is exemplary, please refer to Figure 1 As shown, Figure 1 The schematic diagram of the structure of the elastic tunnel webbing provided in the embodiment of the present application is as follows: The elastic tunnel webbing of the present application can be used for tightening the waist of trousers such as pants.

[0043] In order to more clearly illustrate the structure of the elastic tunnel webbing, the elastic tunnel webbing will be introduced below with reference to the accompanying drawings.

[0044] For example, see Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of the elastic tunnel webbing provided in an embodiment of the present application.

[0045] An elastic tunnel webbing of one embodiment includes a tunnel portion 102 woven from warp yarns and weft yarns and a non-tunnel portion 101. The tunnel portion 102 is used for the rope belt 200 to pass through. The surface band of the tunnel portion 102 (the surface band refers to the surface facing outward) has at least one tunnel opening 104. There are two situations in which both ends of the tunnel portion 102 are opened. The tunnel opening is formed by weaving or the tunnel portion 102 produces the tunnel opening 104 by cutting. The warp yarns are elastic yarns and non-elastic yarns. The weft yarns are non-elastic yarns. The warp yarn density of the tunnel portion 102 is greater than the warp yarn density of the non-tunnel portion 101. The yarn structure of the tunnel portion 102 is a hollow structure, and the hollow structure can be formed using one or two groups of weft yarns.

[0046] When using a set of weft yarns: In the two separate warp yarns, the weft yarns are alternately inserted from the surface layer into the inner layer, and then from the inner layer into the surface layer to form a hollow structure (see Figure 4 As shown, Figure 4 A schematic diagram of a set of hollow weft yarns when weaving elastic tunnel webbing).

[0047] When two sets of weft yarns are used: the two weft yarns enter the two separate layers of warp yarns at the same time, one weft yarn weaves the surface layer, and the other weft yarn weaves the inner layer to form a hollow structure (see Figure 5 As shown, Figure 5 Schematic diagram of two sets of hollow weft yarns when weaving elastic tunnel webbing).

[0048] The yarns at both ends of the tunnel portion 102 are solid (see Figure 6 As shown, Figure 6 Schematic diagram of the solid structure when weaving elastic tunnel webbing).

[0049] The yarn structure of the non-tunnel portion 101 is a solid structure.

[0050] In some of these embodiments, the elastic yarn has a yarn elastic elongation greater than or equal to 20%.

[0051] In some embodiments, the elastic tunnel webbing has a warp density of 70.0 needles / cm to 130 needles / cm, and a weft density of 8.0 needles / cm to 20 needles / cm.

[0052] For example, in one embodiment, the warp density of the elastic tunnel webbing is 70.0 warp / cm; in another embodiment, the warp density of the elastic tunnel webbing is 130 warp / cm; it is not difficult to understand that in other embodiments, the warp density of the elastic tunnel webbing can also be 80.0 warp / cm, 90.0 warp / cm, 100.0 warp / cm, 110.0 warp / cm, 120.0 warp / cm or other values. For example, in one embodiment, the weft density is 8.0 weft / cm; in another embodiment, the yarn density is 20 weft / cm; it is not difficult to understand that in other embodiments, the yarn density can also be 9.0 weft / cm, 10.0 weft / cm, 11.0 weft / cm, 12.0 weft / cm, 13.0 weft / cm, 14.0 weft / cm, 15.0 weft / cm, 16.0 weft / cm, 17.0 weft / cm, 18.0 weft / cm, 19.0 weft / cm or other values.

[0053] In some of the embodiments, the elastic tunnel band is a weft-weight fabric. In the present application, when weaving, each stitch refers to the weft needle weaving back and forth once, and two weft yarns are woven back and forth each time, which is equivalent to one stitch.

[0054] In some embodiments, the weave structure of the elastic tunnel belt is a plain weave, a twill weave or a combined weave. Preferably, the weave structure of the elastic tunnel belt is a twill weave. Figure 3 shown.

[0055] One embodiment provides a method for preparing an elastic tunnel webbing.

[0056] A method for preparing an elastic tunnel webbing comprises the following steps:

[0057] The tunnel portion 102 and the non-tunnel portion 101 are woven with warp yarns and weft yarns. The warp yarn density of the tunnel portion 102 is greater than that of the non-tunnel portion 101. The yarn structure of the tunnel portion 102 is hollow, and the yarn structure of the non-tunnel portion 101 is solid. The surface band of the tunnel portion 102 is provided with a tunnel opening 104 to form an elastic tunnel webbing.

[0058] In some embodiments, when the tunnel portion 102 is provided with a tunnel opening 104, the following steps are included:

[0059] The connection between the tunnel portion 102 and the non-tunnel portion 101 adopts a hollow structure; by adopting the hollow structure, the connection between the tunnel portion 102 and the non-tunnel portion 101 can be left empty to achieve an opening.

[0060] Alternatively, the predetermined position of the tunnel portion 102 is cut to form the tunnel opening 104, and the cutting temperature is 220°C-500°C. The temperature range used for cutting the elastic tunnel webbing when opening is 220°C-500°C. When the temperature is lower than 200°C, no incision can be formed. When the temperature is lower than 220°C, unmelted particles will appear unevenly at the opening of the elastic tunnel webbing, resulting in an unsightly appearance; when the temperature is higher than 500°C, the elastic tunnel webbing will turn yellow at the opening, affecting product quality.

[0061] It should be noted that, when weaving, a semi-finished product of a certain length can be continuously woven, with multiple openings on the semi-finished product, and then the semi-finished product is cut according to a preset size to obtain multiple belts with a length of 88 cm, and a single-sided opening is made at 3 cm from the edge at both ends of the belt to form the above-mentioned tunnel opening 104, forming an elastic tunnel webbing, or, when weaving, a belt with a length of 88 cm is woven, and a single-sided opening is made at 3 cm from the edge at both ends of the belt to form the above-mentioned tunnel opening 104.

[0062] In some embodiments, the method for preparing the elastic tunnel webbing further includes the following steps:

[0063] The elastic tunnel webbing is post-finished using a finishing machine at a temperature range of 100°C-170°C.
