Description

Technical Field

[0001] This utility model relates to the field of disposable underwear technology, and in particular to an elastic, dynamically adaptive disposable underwear. Background Technology

[0002] With the upgrading of consumer demand and the enhancement of hygiene awareness, disposable underwear has become a widely used hygiene product in daily travel, medical care and other scenarios.

[0003] However, the elasticity of existing disposable underwear products cannot provide a comfortable wearing experience. For example, although knitted fabric products have a certain degree of elasticity, the elasticity is mainly achieved through the knitted structure of the fabric itself. After long-term stretching, they are prone to loosening, and the elasticity distribution is not uniform enough, making it difficult to conform to the body's curves. In particular, the waist and leg circumference often cause discomfort due to excessive compression or loosening. Spunbond fabric products can achieve local elasticity through composite elastic fibers or films, but these materials have poor breathability and are prone to causing stuffiness. Although spunlace fabric products have good breathability and are comfortable to wear, their elasticity is poor, resulting in a poor wearing experience.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides an elastic, dynamically adaptive disposable underwear, which solves the problem that the elastic distribution of existing products is difficult to conform to the curves of the human body.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An elastic, dynamically adaptive disposable underwear includes an underwear body comprising a front waistband area, a back waistband area, and a crotch area. The front waistband area and the back waistband area form a waist opening, and the front waistband area, the back waistband area, and the crotch area form a leg opening. The front waistband area includes a front waist portion and a front abdomen; the back waistband area includes a back waist portion and a back buttocks portion; the front waist portion and the back waist portion are provided with a first elastic body, the front abdomen portion is provided with a second elastic body, and the back buttocks portion is provided with a third elastic body.

[0008] The elastic forces of the first elastic body, the second elastic body, and the third elastic body are Q1, Q2, and Q3, respectively, satisfying Q1 > Q3 > Q2.

[0009] In the above structure, the first elastic body is provided with 4-6 waist elastic bands, and the spacing between adjacent waist elastic bands is 3mm.

[0025] The following is in conjunction with the appendix Figure 1-2 The present invention will be further described below.

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figure 1 This utility model discloses an elastic, dynamically adaptive disposable underwear, which includes an underwear body 10. The underwear body 10 includes a front waist area 1, a back waist area 2, and a crotch area 3. The front waist area 1 and the back waist area 2 form a waist opening, and the front waist area 1, the back waist area 2, and the crotch area 3 form leg openings on both sides. The front waist area 1 includes a front waist portion 11 and a front abdomen 12, and the back waist area 2 includes a back waist portion 21 and a back buttocks 22. A first elastic body 4 is provided on the front waist portion 11 and the back waist portion 21, a second elastic body 5 is provided on the front abdomen 12, and a third elastic body 6 is provided on the back buttocks 22. The elastic forces of the first elastic body 4, the second elastic body 5, and the third elastic body 6 are Q1, Q2, and Q3, respectively, satisfying Q1 > Q3 > Q2. The positions of the first elastic body 4, the second elastic body 5, and the third elastic body 6 correspond to the waist and hip area, the front abdomen 12, and the back buttocks 22 of the human body when wearing the garment.

[0028] This invention differentiates the elasticity of the waist and hip area, the front abdomen 12, and the back buttocks 22 according to the curves of the human body and the functional needs of different parts of the body. Specifically, the elasticity of the waist and hip area is greater than that of the back buttocks 22, and the elasticity of the back buttocks 22 is greater than that of the front abdomen 12. The waistband has relatively greater elasticity, allowing it to stretch and contract with walking, sitting, standing, or bending over, maintaining a snug fit and effectively preventing the underwear from slipping or shifting. The greater elasticity also allows it to accommodate a wider range of waist sizes. The buttocks are one of the areas with the greatest range of motion in the human body. When squatting, bending over, sitting, or raising the legs, the skin and muscles of the buttocks and hips will stretch and deform significantly. In contrast, the range of motion of the front abdomen 12 is much smaller. Therefore, the elasticity of the back buttocks 22 is set to be greater than that of the front abdomen 12, leaving "margin" for large-scale movements. This ensures that the disposable underwear can still comfortably fit the body curves during activities, rather than becoming a constraint on movement. This design allows the disposable underwear to provide sufficient elasticity and wrapping force in the back buttocks 22 to effectively fit the back buttocks 22 of the human body, dynamically conforming to various movements of the human body.

[0029] In this embodiment, the underwear body 10 is made of 100% cotton spunlace nonwoven fabric. Using 100% cotton spunlace nonwoven fabric as the base material effectively solves the problem of lint shedding in existing knitted fabrics, and effectively improves the comfort and breathability of disposable underwear. Moreover, the entire production process, from base material to finished product, is automated, minimizing the risk of environmental pollution during production. In addition, 100% cotton spunlace nonwoven fabric is more easily degraded after use, which greatly enhances its environmental protection properties and meets the requirements of sustainable development.

[0030] Furthermore, the first elastic body 4 is provided with 4-6 waist elastic bands, the spacing between adjacent waist elastic bands is 3mm, and the elongation ratio of the waist elastic bands is 1.8 times to 2.0 times. The waist elastic bands extend along the width direction of the underwear body 10, and multiple waist elastic bands are arranged along the height direction of the underwear body 10.

[0031] In one specific embodiment, the first elastic body 4 is provided with 4 waist elastic bands, the spacing between adjacent waist elastic bands is 3mm, and the elongation ratio of the waist elastic bands is 1.8 times to 2.0 times.

[0032] Alternatively, the first elastic body 4 is provided with 5 waist elastic bands, the spacing between adjacent waist elastic bands is 3mm, and the elongation ratio of the waist elastic bands is 1.8 times to 2.0 times.

[0033] Alternatively, the first elastic body 4 is provided with 6 waist elastic bands, the spacing between adjacent waist elastic bands is 3mm, and the elongation ratio of the waist elastic bands is 1.8 times to 2.0 times.

[0034] The elastic waistband is evenly distributed in the front waistband 11 and the back waistband 21 to form a wide and elastic waistband. This can evenly distribute the pressure required for fixation to a larger area of ​​skin, effectively reducing the possibility of marks forming in the waist and hip area and improving wearing comfort.

[0035] Furthermore, the second elastic body 5 is provided with 4-6 abdominal elastic bands, the spacing between adjacent abdominal elastic bands is 5mm, and the stretch ratio of the abdominal elastic bands is 1.3-1.4 times.

[0036] In one specific embodiment, the second elastic body 5 is provided with 4 abdominal elastic bands, the spacing between adjacent abdominal elastic bands is 5mm, and the stretch ratio of the abdominal elastic bands is 1.3 to 1.4 times.

[0037] Alternatively, the second elastic body 5 is provided with 5 abdominal elastic bands, with a spacing of 5mm between adjacent abdominal elastic bands, and the stretch ratio of the abdominal elastic bands is 1.3 to 1.4 times.

[0038] Alternatively, the second elastic body 5 is provided with 6 abdominal elastic bands, with a spacing of 5mm between adjacent abdominal elastic bands, and the stretch ratio of the abdominal elastic bands is 1.3 to 1.4 times.

[0039] The front abdomen section 12 features a certain degree of elasticity, and the spacing between the elastic bands is increased. This reduces the elasticity of the front abdomen section 12, providing good support and deformation, and effectively adapting to users of different body types. Increasing the spacing between the elastic bands in the front abdomen section 12 also improves breathability, effectively reducing stuffiness and enhancing wearing comfort.

[0040] Furthermore, the third elastomer 6 is provided with 12-13 hip elastic bands, with a spacing of 13mm between adjacent hip elastic bands, and the stretch ratio of the hip elastic bands is 1.3-1.4 times.

[0041] In one specific embodiment, the third elastic body 6 is provided with 12 hip elastic bands, the spacing between adjacent hip elastic bands is 13mm, and the stretch ratio of the hip elastic bands is 1.3 to 1.4 times.

[0042] Alternatively, the third elastomer 6 is provided with 13 hip elastic bands, with a spacing of 13mm between adjacent hip elastic bands, and the stretch ratio of the hip elastic bands is 1.3 to 1.4 times.

[0043] The wider spacing of the elastic bands at the buttocks effectively disperses the pressure on the back buttocks 22, allowing the tension to be distributed more evenly across the entire surface of the back buttocks 22 of the underwear body 10, avoiding the possibility of tight marks caused by dense elastic bands; in addition, the wider spacing of the elastic bands at the buttocks gives the fabric of the back buttocks 22 greater freedom of stretch, allowing it to better conform to the three-dimensional contour of the human buttocks, and has higher breathability, which helps to improve wearing comfort.

[0044] Furthermore, a fourth elastic body 7 is symmetrically arranged on both sides of the crotch area 3 to increase the elasticity of the crotch area 3 on both sides. The fourth elastic body 7 is provided with two crotch elastic bands, the distance between the two crotch elastic bands is 5mm, and the stretch ratio of the crotch elastic bands is 1.1 times.

[0045] Furthermore, two S-elastic bands 8 are respectively installed between the crotch area 3 and the front waist area 1, and between the crotch area 3 and the back waist area 2. When worn, the S-elastic bands 8 are positioned corresponding to the lower edge of the waist and abdomen and the lower edge of the buttocks. The installation of the S-elastic bands 8 helps to provide better support in key areas, while maintaining wearing comfort and a natural appearance.

[0046] The inclusion of S-elastic bands 8 and crotch elastic bands on opposite sides of the crotch area 3 ensures that the underwear body 10 has elasticity at the leg opening edges. The S-elastic bands 8 and crotch elastic bands provide continuous and stable contraction force, tightly fitting the leg opening edges to the upper thigh, effectively reducing the possibility of fabric curling or shifting due to movement. Furthermore, the highly elastic leg openings can flexibly fit different user leg sizes, enhancing the product's versatility. The crotch elastic bands are set with a relatively low stretch ratio, effectively reducing the possibility of indentations.

[0047] Reference Figure 1 In one embodiment, the S elastic band 8 is distributed in a point-break pattern at the crotch area 3, with a point-break blade spacing of 1.2 mm, a coverage area length (along the crotch length direction) of 90 mm, and a width (along the width direction of the underwear body 10) of 30 mm.

[0048] Reference Figure 2 In another embodiment, the S elastic band 8 is cut off at the crotch area 3, covering an area with a length of 90mm and a width of 30mm.

[0049] That is, the elasticity of the S elastic band 8 does not act within the 90mm*30mm area of ​​the crotch region 3.

[0050] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
