Description

Technical Field

[0001] The invention relates to the field of disposable underwear, in particular to a wear-reducing disposable underwear and a production process thereof. Background Art

[0002] Disposable underwear is low-cost and can be thrown into the trash after use without having to be washed, making it convenient for people to use when traveling or for women to use during their menstrual period.

[0003] The front and back pieces of underwear are usually connected on both sides of the underwear. The thickness of the connection is obviously higher than the thickness of other parts of the underwear, which leads to friction between the connection and the sides of the human body, especially when lying on the side, which makes the foreign body sensation obvious and the comfort poor. In order to reduce the foreign body sensation, the connection can be moved to the position on the underwear corresponding to the groin of the human body, but the thickness of the connection is large, which easily leads to moisture and airtightness in the groin, posing a health hazard and needs to be improved. Summary of the invention

[0024] The beneficial effects of the present invention are as follows: a wear-reducing disposable underwear and a production process thereof, wherein the connection between the first sealing part and the second sealing part is designed to be on the front side of the abdomen, which can correspond to the groin, thereby avoiding friction between the connection and both sides of the human body and the foreign body sensation when lying on the side, and utilizing the design of the wear-reducing holes to further reduce the contact area between the first sealing part or the second sealing part and the groin, thereby reducing friction and improving the ventilation effect, which is beneficial to the health of the groin. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 It is a schematic diagram of the structure of the present invention;

[0026] Figure 2 yes Figure 1 Schematic diagram of the expanded structure;

[0027] Figure 3 It is a structural schematic diagram of another preferred embodiment of the present invention. DETAILED DESCRIPTION

[0028] Combine the following Figures 1 to 3 The technical solution of the present invention is further illustrated by specific embodiments.

[0029] like Figure 1 The wear-reducing disposable underwear shown in the figure comprises: a front sheet 1, a rear sheet 2 and a crotch 3, wherein the front sheet 1 is arranged in front of the rear sheet 2, the crotch 3 is connected between the front sheet 1 and the rear sheet 2, and the top surface length of the front sheet 1 is less than the top surface length of the rear sheet 2. Figure 2 As shown, a non-equilateral structure is formed which is short in the front and long in the back.

[0030] First sealing parts 5 are respectively provided at the edges of both sides of the front sheet 1, and extension parts 4 extending to the corresponding sides of the front sheet 1 are provided at both sides of the back sheet 2, and second sealing parts 6 overlapping with the first sealing parts 5 are provided at the edges of the extension parts 4 to form an underpants structure. In this embodiment, the first sealing parts 5 and the second sealing parts 6 are ultrasonically welded or glued, and the structure is stable.

[0031] like Figure 1 As shown, the first sealing parts 5 on both sides of the front piece 1 are distributed in a V shape, which can correspond to the groin position of the human body, avoiding the friction between the connection between the first sealing part 5 and the second sealing part 6 and the two sides of the human body and the foreign body feeling when lying on the side. After wearing this friction-reducing disposable underwear, the human body can lie on the side more comfortably.

[0032] like Figure 2 As shown, the first sealing part 5 and / or the second sealing part 6 are provided with friction-reducing holes 7 at intervals, and the friction-reducing holes 7 reduce the contact area between the first sealing part 5 or the second sealing part 6 and the human groin, thereby reducing friction and improving the ventilation effect, which is beneficial to the health of the groin.

[0033] The distribution of the wear-reducing holes 7 is mainly divided into the following three situations:

[0034] 1. The first sealing part 5 is located inside the second sealing part 6, and the wear-reducing holes 7 are distributed on the first sealing part 5. The first sealing part 5 contacts the groin of the human body. The wear-reducing holes 7 distributed on the first sealing part 5 can reduce the contact area between the first sealing part 5 and the groin of the human body, reduce friction, and improve the air permeability of the groin environment;

[0035] 2. The second sealing part 6 is located inside the first sealing part 5, and the wear-reducing holes 7 are distributed on the second sealing part 6. At this time, the second sealing part 6 is in contact with the human groin, and the wear-reducing holes 7 distributed on the second sealing part 6 can reduce the contact area between the second sealing part 6 and the human groin;

[0036] 3. The wear-reducing holes 7 are distributed on both the first sealing part 5 and the second sealing part 6. No matter the first sealing part 5 or the second sealing part 6 contacts the human body, the wear-reducing holes 7 can reduce the contact area.

[0037] In this embodiment, the front piece 1, the extension part 4, the back piece 2 and the crotch part 3 adopt an integrated fabric cutting structure, and can use non-woven fabric as a raw material for cutting and forming, which is low in cost.

[0038] Figure 3 As shown, in order to improve the stability and comfort of the wear-reducing disposable underwear after wearing, an elastic waist 8 is also needed. The elastic waist 8 includes a circle of cloth set on the top of the front piece 1, the extension part 4 and the back piece 2. The cloth set is provided with elastic rubber bands, which are elastic and comfortable, prevent the wear-reducing disposable underwear from falling off, and improve the adaptability to the waist circumference of the human body.

[0039] Embodiment 1:

[0040] A production process for underwear, comprising the following steps:

[0041] Cutting: Use electric scissors to cut the front sheet 1, the extension 4, the back sheet 2 and the crotch 3 on the non-woven fabric to obtain a flat piece of fabric, such as Figure 2 As shown;

[0042] Punching: stacking and punching the cloth pieces to obtain wear-reducing holes 7 distributed at intervals on the first sealing portion 5 and / or the second sealing portion 6;

[0043] Sealing: Flip the front sheet 1 upward to the front of the back sheet 2, and flip the extension inward to the corresponding side of the front sheet 1, such as Figure 1 As shown, the first sealing part 5 and the second sealing part 6 are overlapped, and it is ensured that at least one set of wear-reducing holes 7 is located on the first sealing part 5 or the second sealing part 6 in contact with the human body, and the first sealing part 5 and the second sealing part 6 are sealed by glue or ultrasonic welding, and the contact between the sealing position and the human body is reduced by the wear-reducing holes 7.

[0044] Embodiment 2:

[0045] A production process for underwear, comprising the following steps:

[0046] Cut: As Figure 2As shown, the front sheet 1, the extension 4, the back sheet 2 and the crotch 3 are cut in an integrated manner to obtain a flat sheet of fabric, and the first sealing portion 5 and the second sealing portion 6 are made to correspond to the groin position of the human body;

[0047] Sealing: Flip the front sheet 1 to the front of the back sheet 2, flip the extension part to the corresponding side of the front sheet 1, overlap the first sealing part 5 and the second sealing part 6, and seal the first sealing part 5 and the second sealing part 6 by glue or ultrasonic welding. Figure 1 As shown, the structure is solid;

[0048] Punching: Punching the overlapping first sealing part 5 and the second sealing part 6 to obtain spaced wear-reducing holes 7, which are spaced along the groin of the human body to reduce friction with the groin and improve the air permeability of the underwear at the groin position;

[0049] Installation of elastic waist 8: Figure 3 As shown, elastic rubber bands are filled into the annular cloth cover to form an elastic waist 8, and the cloth cover is fixed to the top of the front piece 1, the extension part 4 and the back piece 2 by ultrasonic welding to form elastic and comfortable underwear.
