Description

Technical Field

[0001] This utility model relates to the field of clothing technology, and in particular to a pair of long-distance running shorts. Background Technology

[0002] With the rise of running as a national sport, the number of people joining the running community is increasing, thus placing higher demands on running gear. Compression shorts, due to their ability to effectively reduce thigh muscle tremors, alleviate muscle fatigue, and prevent chafing on the inner thighs, have become favored by elite runners. Wearing this type of clothing has become mainstream in international marathons, and elite Chinese athletes such as Yang Shaohui and Wu Xiangdong have also chosen to use these shorts in their races. Common compression shorts on the market are generally made using the following methods:

[0003] (1) Material usage: The most popular tight-fitting shorts on the market are made of polyester and nylon, with a weight of about 200g. To ensure excellent elasticity, the spandex content is generally above 20%. Both weft knitting and warp knitting structures are available. Warp knitting structures generally have a stronger sense of compression.

[0004] (2) Waist structure: For women's tight-fitting shorts, a double-layer fabric with an elastic waistband is generally used, or shaping yarn is added to increase the stability of the waist structure. The waistband width is generally around 9 cm. This type of waistband has good stability, even pressure distribution, and good comfort. However, because it has a 2-3 layer structure, its breathability is poor, especially in the pocket area, which has a 5-layer structure, making it even less breathable. The waistband area is prone to sweating, and during long-distance running, the skin is in prolonged contact with the wet clothing, making the abdomen prone to getting cold and causing skin itching. For men's tight-fitting pants, an elastic waistband is generally used, with a waistband width of about 4 cm. Elastic waistbands have good stability, but they are thick and have poor breathability. The width used in clothing is generally narrow, otherwise it will greatly reduce the wearing comfort. Therefore, the waist is not evenly pressured by the clothing, which can easily cause marks and skin chafing during long-distance running.

[0005] Chinese patent application number 202322239895.1 discloses a wrinkle-free elastic waistband, comprising an inner fabric, an elastic band, and an outer fabric. The inner fabric, elastic band, and outer fabric are connected layer by layer to form a single structure. A first connecting part is provided between the inner fabric and the elastic band, and multiple second connecting parts are provided between the elastic band and the outer fabric. A gap is formed between adjacent first connecting parts and adjacent second connecting parts. The elastic band is hidden between the inner and outer fabrics, and both the inner and outer fabrics are made of highly elastic flat fabric. This results in a smooth, wrinkle-free waistband with an attractive appearance and does not affect the breathability of the waist area. The connecting parts of the outer fabric, elastic band, and inner fabric are spaced at equal or varying intervals, allowing them to fully stretch under external force, improving the elasticity of the waistband. However, prolonged running can easily cause marks and chafing, resulting in poor comfort.

[0006] Chinese Patent Application No. 201720892484.4 discloses a comfortable and health-enhancing tights. The shorts, from top to bottom, consist of a waistband, an abdominal binder, and leg binders on the front, with a corresponding hip section on the back. The waistband includes a built-in waistband that wraps around the waist. The abdominal binder has two symmetrically arranged longitudinal abdominal binders and two symmetrically arranged diagonal abdominal binders in a figure-eight pattern. The leg binders have two symmetrically arranged longitudinal leg binders. The upper ends of the two longitudinal abdominal binders are connected to the waistband, and the lower ends extend to the inside of the leg binders and connect together. The upper end of the diagonal abdominal binder is connected to the middle of the longitudinal abdominal binders, and the top of the longitudinal leg binders is connected to the diagonal abdominal binders. A far-infrared layer is provided in the abdominal binder between the two longitudinal abdominal binders. This invention improves the structure of the tights to meet the requirements of fitting the contours of the body while also providing breathability for heat dissipation and perspiration, resulting in a comfortable and refreshing fit. However, the waistband of these shorts is made of a single layer of fabric, which lacks elasticity and binding strength, making it prone to slipping down. Utility Model Content

[0007] Therefore, in view of the above problems, this utility model provides a long-distance running shorts, which solves the problems that the waist fabric of existing running shorts is prone to slipping down, causing gaps and sagging during exercise, as well as poor breathability and comfort.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A type of long-distance running shorts includes a shorts body, defined as having a longitudinal direction along the length of the shorts and a transverse direction along the width of the shorts. The shorts body is a first fabric layer woven from a first nylon and a first spandex. The longitudinal elongation of the shorts body is greater than the transverse elongation. When worn statically, the elongation of the shorts body is 10%-20%, and when in motion, the elongation of the shorts body is 20%-50%. Furthermore, when in motion, the elongation of the shorts body corresponding to the hip and knee joint areas is >40%. The waist of the shorts body has a double-layer structure, the longitudinal distance of which gradually increases from the waist area to the abdomen area. The double-layer structure includes an inner first fabric layer and an outer second fabric layer. An adhesive layer, composed of several dots of adhesive, is provided between the first and second fabric layers. When worn statically, the elongation of the double-layer structure is 15%-20%, and when in motion, the elongation of the double-layer structure is >30%. The second fabric layer is a warp-knitted mesh structure woven from a second nylon and a second spandex.

[0010] Furthermore, the yarn padding numbers of the warp-knitted mesh structure are 1-0, 1-2, 1-0, 1-2, 2-3, 2-1, 2-3, 2-1 / 5-6, 5-4, 5-6, 5-4, 4-3, 4-5, 4-3, 4-5 / 6-7, 7-6, 6-7, 7-6, 6-7, 7-6, 6-7, 7-6 / / .

[0011] Furthermore, the longitudinal distance between the double-layered structures in the lumbar region is 6.5-8cm, and the longitudinal distance between the double-layered structures in the abdominal region is 8-10cm.

[0012] Furthermore, the weight of the shorts body is ≤175g / m². 2 .

[0013] Furthermore, the weight ratio of the first nylon to the first spandex is 16:9.

[0014] Furthermore, the weight ratio of the second nylon to the second spandex is 7:43.

[0015] Furthermore, both the first and second nylon fibers have a specification of 23D / 20F.

[0016] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows:

[0017] 1. During long-distance running, the legs alternately lift and lower, the waist alternately twists and turns, and the runner's waist circumference fluctuates constantly due to breathing. If only a single layer of the first fabric is used as the waist belt, it will inevitably cause drastic fluctuations in the waist clothing pressure, and the hip and leg clothing pressure will intermittently increase. The single layer of the first fabric has insufficient elasticity and binding force, and cannot offset the pressure difference between the waist and hips. When the waist clothing pressure is less than the hip and leg clothing pressure, the waist fabric will slide down, even causing gaps or sagging in the crotch. In severe cases, it can lead to skin abrasions and affect running performance. Therefore, the first fabric layer is bonded to the second fabric layer. Because the second fabric layer has a high content of spandex, a stable elastic structure is formed after bonding. During running, the waist belt is in a dynamic stretching state due to the stretching and contraction of the waist skin and the changes in waist circumference during breathing. When the waist belt is in a small stretching state (stretch rate of about 15%), there is a larger tensile force; when the waist belt is in a high stretching state (stretch rate greater than 30%), the tensile force tends to be gentle. That is, during running, the pressure fluctuation of the clothing is gentle, and it is not easy to form a high pressure difference that would cause the waist belt to be pulled down. After bonding, the coefficient of friction of the waist belt increases, and the waist belt forms a large static friction force with the skin. The waist belt adheres tightly to the skin and is not easy to slip on the skin surface, thus preventing the waist belt from slipping down during running.

[0018] 2. The longitudinal stretch rate of the shorts is set to be greater than the lateral stretch rate, meaning that the longitudinal stretch force is smaller. This ensures that the fabric can easily stretch and deform with the skin during running, reducing energy loss. More importantly, due to the smaller longitudinal stretch force, the dynamic clothing pressure change in the legs is smaller, and the clothing pressure difference between the hips, legs, and waist is also smaller. The force exerted by the legs and hips on the waistband is also smaller, resulting in a smooth change in waistband tension and small fluctuations in clothing pressure. Runners do not experience a feeling of tightness or looseness, resulting in high comfort. This meets the restraint required for long-distance running and ensures that the waistband does not move downwards or sag.

[0019] 3. The longitudinal distance of the double-layer structure gradually increases from the waist area to the abdomen area. On the one hand, it can tighten abdominal fat to achieve a flattering effect and look more aesthetically pleasing. On the other hand, the larger abdominal coverage area increases the contact area and further increases the static friction between the belt and the skin, reducing the risk of belt slippage.

[0020] 4. Compared with traditional multi-layer or elastic waistband structures, the waist structure of this invention offers significantly improved breathability. The adhesive in the double-layer structure is distributed in a dotted pattern, reducing its impact on the overall breathability of the waistband. Furthermore, the second fabric layer uses a warp-knitted mesh structure, increasing the overall permeability of the waistband. Therefore, heat generated during running and moisture produced by the skin can be expelled through the pores, improving runner comfort. Moreover, compared to traditional multi-layer or elastic waistband structures, the thickness of the waistband structure in this invention is significantly reduced, facilitating rapid sweat evaporation. Additionally, the excellent breathability of the waistband increases airflow, further accelerating sweat evaporation and reducing sweat accumulation in the waist area.

[0021] 5. During long-distance running, there is high-frequency friction on the inner thighs. Using highly abrasion-resistant nylon fibers can increase the durability of running shorts; using microfiber yarn, microfiber has a small initial modulus, and the fabric is soft and comfortable to the touch, making it easy to wear directly against the skin.
