Description

Technical Field

[0001] The present invention relates to a new type of physiological underwear, belonging to the technical field of underwear. Background Art

[0002] A physiological underwear can reduce the sliding of sanitary napkins, maintain breathability, and is used during a woman's physiological period. It can maintain the hygiene of a woman's physiological period to the greatest extent, avoid the harm caused by sultriness to the skin. The special design of the physiological underwear can also keep the sanitary napkin in the best fitting degree, give special care to women during special periods, and make women's menstrual life easier, more convenient, and healthier.

[0003] The existing physiological underwear usually has a waterproof layer and a functional layer provided on the underwear body. The functional layer can adsorb a certain amount of menstrual blood, and the waterproof layer can prevent the adsorbed menstrual blood from penetrating onto the underwear body. At the same time, a sealing strip for preventing side leakage is also provided at the opening edge under the main body of the underwear to prevent side leakage. However, the existing physiological underwear has a poor anti-side leakage effect. Its main body adsorption part lacks a diversion structure. In the case of untimely adsorption, side leakage is likely to occur. Moreover, the main body anti-side leakage structure usually uses elastic fibers with water absorption or waterproof properties to tightly bind the legs to achieve the anti-side leakage function. However, due to different body shapes of each person, even for the same model during use, there will be situations of over-tightening or loosening of the binding, which affects the anti-leakage effect. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Refer to Figures 1-6As shown in the figure, the technical solution adopted in this specific embodiment is as follows: It includes a trouser body, and the trouser body includes a front panel 1 and a rear panel 2. A bottom crotch 3 is provided at the connection of the front end 1 and the bottom of the rear panel 2. The side connection opening below the front panel 1 and the rear panel 2 is the trouser leg. An elastic self-adaptive leak-proof belt 4 is provided at the edge of the trouser leg. The bottom crotch 3 includes a skin-friendly diversion layer 31, a water storage layer 32, a waterproof and breathable layer 33, and a support layer 34. The support layer 34 is the bottom layer and is adhered to the trouser body. In this embodiment, a variety of anti-side leakage structures are adopted. One is the multi-layer structure of the bottom crotch. The skin-friendly diversion layer is the innermost layer structure and is in direct contact with the skin. When menstrual blood is discharged, it can not only quickly absorb and store it through the water storage layer, but also play a role in diversion. The menstrual blood will not flow directly to both sides, but will gradually transition to both sides after diversion and be blocked and absorbed section by section, so that there will be no side leakage situation;

[0025] Second, to further improve the anti-side leakage effect, a self-adaptive leak-proof belt is also provided at the trouser leg. It has elasticity and can adaptively contact the thigh for fastening to prevent menstrual blood from leaking out from the trouser leg in case of an accident. Through these two anti-side leakage structures, it can effectively prevent side leakage when wearing the physiological underwear and avoid embarrassing situations;

[0026] It can be understood that the structure of the physiological pants adopted in this embodiment needs to be used in combination with a tampon or sanitary napkin in the early stage of the female menstrual period. After the menstrual flow decreases, the physiological pants can be directly worn, which is more convenient to use. The water storage layer can effectively adsorb the discharged menstrual blood, and the waterproof and breathable layer can play a role in waterproofing and breathing. In this embodiment, the structure of a seamless underwear is shown. Both the front and rear panels are base cloth layers, made of modal or mulberry silk or graphene materials, with good elasticity and breathability, and are comfortable to wear. According to personal wearing preferences and different stages of the menstrual period, a lace and thong body structure can also be adopted to meet different wearing needs.

[0027] More specifically, the skin-friendly diversion layer 31 is a spandex cotton absorbent layer, made of a blend of 95% 40S pure cotton and 5% 20D spandex. Spandex cotton is a blended fabric of cotton and spandex. The addition of spandex (elastic fiber) gives it elastic properties, being both skin-friendly and elastic, more friendly to the skin, and bringing a more comfortable wearing experience to the user. Similarly, in other embodiments, the skin-friendly diversion layer can also be made of modal or mulberry silk or graphene materials to obtain different wearing experience feelings.

[0028] More specifically, a number of flow guiding strips and isolation strips are provided on the surface of the skin-friendly flow guiding layer 31. The flow guiding strips are arranged longitudinally, and the isolation strips are arranged transversely. The flow guiding strips and the isolation strips divide the skin-friendly flow guiding layer 31 into a rapid water absorption area 311, a transition area 312, and a leakage prevention area 313. The rapid water absorption area 311 is arranged longitudinally along the skin-friendly flow guiding layer 31. The transition area 312 is arranged around the edge of the rapid water absorption area 311. The leakage prevention area 313 is arranged around the edge of the transition area 312. The flow guiding strips include an inner flow guiding strip 315 and a drainage strip 316. The inner flow guiding strip 315 is located at the innermost side of the rapid water absorption area 311 and is arranged in an arc shape opposite to each other. The drainage strips 316 are symmetrically arranged outside the inner flow guiding strip 315, and a plurality of them are arranged at equal intervals. A flow guiding groove 314 is formed between the drainage strip 316 and the inner flow guiding strip 315 and between the drainage strips 316. The isolation strips include two groups of symmetrically arranged first limit isolation strips 317 and second limit isolation strips 318. The two ends of the first limit isolation strip 317 correspond to the ends of the outermost drainage strip 316, leaving a gap. And there is also a gap between the arc section of the first limit isolation strip 317 and the other drainage strips 316. The second limit isolation strip 318 is located inside the first limit isolation strip 317. There is a gap between the two ends of the second limit isolation strip 318 and the ends of the flow guiding strip 315. In this embodiment, a flow guiding structure is adopted. The flow guiding structure can not only position and prevent the cotton strip from slipping, but importantly, it can also play a role in guiding the menstrual blood. It can be understood that the physiological pants described in this embodiment are not only mainly used for women's menstrual periods, but can also be used by infants or the elderly who are prone to leakage. During use, when menstrual blood or urine is discharged, it will first be discharged to the rapid water absorption area. Since the open area of the bottom crotch corresponds to the position of the urethral orifice, when menstrual blood or urine is discharged, it is first absorbed by the rapid water absorption area and then penetrates into the water storage layer. When the discharge volume is large and cannot be absorbed immediately, it will flow to both ends and be guided by the inner flow guiding strip and flow into the drainage grooves on both sides through the gaps between the two ends and the isolation strips for absorption. Under the blocking effect of the inner flow guiding strip, although it is mainly used for guiding, in this embodiment, the flow guiding strips and the isolation strips are only slightly higher than the surface of the skin-friendly flow guiding layer, and there will be no discomfort during wearing. When the amount of menstrual blood or urine is too large and cannot quickly enter the drainage grooves from both ends at intervals, it can directly overflow the inner flow guiding strip and enter the drainage grooves directly. The multi-level and step-by-step arrangement of the drainage grooves can effectively guide the flow direction of menstrual blood or urine and prevent it from directly penetrating out from both sides. When the drainage groove area is fully adsorbed or cannot be quickly adsorbed, it can enter the transition area for absorption, and finally, the thicker leakage prevention area blocks the edge. The leakage prevention area is set higher than the flow guiding strips and the isolation strips. After the menstrual blood or urine is absorbed through multiple levels of flow guiding, it is blocked by the leakage prevention area and there will be no penetration and side leakage. The absorption structure of traditional physiological underwear lacks a flow guiding structure. When menstrual blood cannot be absorbed in time, it will directly flow out to both sides. Although there is also a leakage prevention structure at the edge, when the amount is large or the movement is large, there will still be penetration and side leakage. After adopting the multi-level flow guiding structure of this embodiment,The menstrual blood is absorbed step by step and finally blocked, so there will be no side leakage;

[0029] Especially when infants or the elderly wearers are wearing, even when the urine leakage volume is large, side leakage is not likely to occur. It can be understood that the physiological underwear worn by infants or the elderly has a relatively thick water storage layer, and the designed water storage capacity is 350-450 ml, so it can replace the use of diapers;

[0030] In this embodiment, the skin-friendly diversion layer is still in a V-shaped diversion channel structure, with the middle of the drainage groove being low and both sides being high, and the diversion and absorption effect is better.

[0031] More specifically, the crotch 3 extends backward to the back panel 2 to form an anti-permeation area 319. The anti-permeation area 319 is a long and narrow structure. According to ergonomics, the long and narrow anti-permeation area contacts the buttocks from the middle seam of the buttocks, increasing the contact surface with the skin and improving the water absorption effect. Since this is not in the direct absorption position, there is no need to set a diversion structure, and a good skin-friendly water absorption effect can also be obtained.

[0032] More specifically, the water storage layer 32 is a composite water absorption layer of 160D polyester and 19.4% sea-island fiber, with a porosity of 35-40%, and a Z-shaped knitting structure. The waterproof and breathable layer 33 is a 75D semi-dull polyester low-elastic fiber-based waterproof film layer. In this embodiment, the water storage layer and the waterproof and breathable layer are the main functional layers, which are double-layer composite layers, bonded by ultrasonic technology or environmentally friendly glue, improving the breathable effect while being waterproof;

[0033] The support layer 34 is a mixed fabric layer of 70D nylon filament and 14.2% spandex, with a thickness of 0.15-0.25 mm and a gram weight of 120-150 g / m 2 , and the tensile recovery rate ≥ 95%, effectively supporting and protecting the whole, ensuring the contact effect with the skin, and thus effectively achieving the water absorption and anti-leakage effect.

[0034] More specifically, the adaptive leak-proof belt 4 includes a waterproof elastic fiber layer 41. Inside the outer side of the waterproof elastic fiber layer 41, a shape memory alloy wire 42 is arranged. The head and tail of the shape memory alloy wire 42 are connected end to end to form a ring structure. In this embodiment, the adaptive leak-proof belt not only uses a waterproof elastic fiber as the main binding structure, with an arc-shaped edge design and a curvature radius R = 35 - 40 mm, and uses a 0.8 mm wide ultrasonic welding belt to achieve the effect of tight and loose wearing. At the same time, a shape memory alloy wire is used as the fastening structure at the edge, with a diameter of 0.05 mm and a nickel-titanium alloy proportion of 52%. It generates a shrinkage of 0.5 - 1 mm in the temperature range of 35 - 40 °C. The longitudinal distribution density is: 8 - 10 wires / cm in the central area, decreasing to 5 - 6 wires / cm on both sides. Pre-deformation treatment: A preset tensile strain of 0.3 - 0.5% is set at 25 °C. In this embodiment, 8 wires are arranged in the central area and 5 wires are arranged at the edge, so that it can automatically tighten during wearing, achieving the wearing fastening effect for different users and effectively playing a role in preventing side leakage.

[0035] More specifically, the front waistband 15 and the rear waistband 21 with the same structure are respectively arranged at the tops of the front panel 1 and the rear panel 2. A number of anti-slip silica gel strips 151 are arranged at intervals on the inner side of the front waistband 15. The front waistband 15 includes an inner elastic layer 152 and an outer elastic layer 153. The inner elastic layer 152 is a blended layer of 40S combed cotton and 5% spandex, and the outer elastic layer 153 is a blended layer of 70D nylon and 14.2% spandex. In this embodiment, a double-layer elastic band with a width of 20 - 25 mm is used. The inner layer is a blend of 40S combed cotton and 5% spandex, with an elastic modulus ≤ 1.5 MPa. The outer layer is a blend of 70D nylon and 14.2% spandex, with an elastic modulus of 3 - 4 MPa. Anti-bacterial silica gel anti-slip strips are arranged on the inner side, with a width of 2 mm, a height of 0.3 mm, and a spacing of 10 mm. Base rubber: 70 - 75% methyl vinyl silicone rubber (VMQ). Functional additives: 5 - 8% nano zinc oxide (particle size 30 - 50 nm) + 3 - 5% silver-loaded zeolite (Ag content 2 - 3%). Surface friction coefficient μ = 0.4 - 0.6. During wearing, it not only has good wearing comfort, but also can effectively prevent the waistband from loosening and displacing through the setting of the silica gel anti-slip strips, ensuring the leak-proof effect.

[0036] Working principle of the present invention: When the menstrual flow is heavy in the initial stage of the menstrual period, it is used in conjunction with a tampon or sanitary napkin. Since the skin-friendly diversion layer 31 is provided, the diversion strip can limit the tampon placed on it, preventing it from moving left and right to a certain extent, while the isolation strip can prevent it from moving back and forth. Therefore, it can play a certain anti-slip role for the tampon during use, reducing the occurrence of side leakage. Secondly, when the tampon is full of menstrual blood, the exuded menstrual blood flows into the rapid water absorption area 311 and quickly penetrates into the lower water storage layer 32 to be absorbed and stored. At the same time, it is blocked by the waterproof and breathable layer 33 and will not penetrate to the base fabrics of the front panel 1 and the rear panel 2 anymore, effectively preventing pollution. And when wearing, when the body temperature rises, the memory metal wire 42 will undergo a slight contraction, further fastening to the thigh root. In case of accidental side leakage, it will not directly leak out but be absorbed by the trouser body. In addition, after the menstrual flow decreases in the later stage of the menstrual period, there is no need to use a tampon or a sanitary pad. When a small amount of menstrual blood is discharged, it is directly discharged onto the rapid water absorption area 311 and absorbed and stored. If the menstrual blood is discharged too fast and is not instantly absorbed by the central rapid water absorption area 311, it will flow from both ends of the inner diversion strip 315 into the diversion grooves 314 in the adjacent intervals and be gradually absorbed. The layered diversion and absorption can effectively prevent the menstrual blood from flowing out directly from both sides irregularly when it fails to be absorbed in time, resulting in side leakage. Since a variety of blended materials are used, after the menstrual blood is absorbed and stored, it only needs to be put into water for cleaning and can be used again, improving the reusability of the menstrual pants and reducing waste.

Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
