[0039] Figure 1 The arrow shown indicates the CD direction.
[0040] Combination Figure 1 and Figure 2 As shown in this embodiment, a disposable trouser-type absorbent product is proposed. When unfolded, the disposable trouser-type absorbent product is divided into a front waist and abdomen area, a crotch area, and a back waist and buttock area from front to back. The disposable trouser-type absorbent product includes a main body 1 and a crotch absorbent sheet 2. The crotch absorbent sheet 2 includes a hydrophilic surface layer, an absorbent core 7, and a bottom leak-proof layer. The absorbent core 7 is provided with an adjustable part that can be horizontally stretched and adjusted. This adjustable part improves the fit of the absorbent core 7 in the groin area, thereby improving comfort during use and reducing the probability of back leakage. The adjustable part is located at the rear end of the absorbent core 7, corresponding to the groin area. The main body 1 has several first elastic bands 4, some of which have a central area overlapping the area where the absorbent core 7 is located.
[0041] In some specific implementations, the main body 1 includes two layers of non-woven fabric 3, with a first elastic band 4 sandwiched between the two layers of non-woven fabric 3; one or more second elastic bands 5 are also sandwiched between the two layers of non-woven fabric 3; the two layers of non-woven fabric 3 are formed into a waistband and legbands through O-shaped cutting and side sealing welding of the waistband; the first elastic band 4 is set in relation to the waistband to provide restraint at the waist, abdomen, and buttocks of the wearer during wear, preventing the disposable trouser-type absorbent product from falling off; the second elastic band 5 is set in relation to the legbands, with a second elastic band 5 set at both the left and right legbands, and the second elastic band 5 can wrap around the leg to provide restraint on the legs of the disposable trouser-type absorbent product, enhancing the fit of the legs.
[0042] The length L of the aforementioned leg opening in the CD direction can be less than 200 mm, preferably less than 150 mm; the width W of the crotch area can be 50-200 mm, preferably 60-170 mm. This structural design facilitates the formation of a boxer brief design at the leg opening, making it easier for disposable trousers to absorb the fabric and maintain its stability during wear, preventing it from shifting.
[0043] One or more drainage grooves 8 are provided on the absorbent core 7 corresponding to the crotch area. Preferably, multiple drainage grooves 8 are provided on the absorbent core 7 corresponding to the crotch area. These drainage grooves 8 can be symmetrically distributed about the centerline of the absorbent core 7. The specific structure of the drainage grooves 8 on the absorbent core 7 can be shown in any of the following examples:
[0044] Example 1, such as Figure 3 As shown, two drainage grooves 8 are provided on the absorber core 7 along the CD direction. The two drainage grooves 8 can be symmetrically distributed about the center line of the absorber core 7 along the CD direction, or they can be symmetrically distributed about the center line of the absorber core 7 perpendicular to the CD direction.
[0045] Example 2, such as Figure 4As shown, four drainage grooves 8 are arranged along the CD direction on the absorber core 7. The drainage grooves 8 are arranged in pairs. The two groups of drainage grooves 8 can be symmetrically distributed about the center line of the absorber core 7 along the CD direction. The drainage grooves 8 in the same group that are close to the tail end of the absorber core 7 can also be symmetrically distributed about the center line of the absorber core 7 perpendicular to the CD direction.
[0046] Example 3, such as Figure 5 As shown, three drainage grooves 8 are provided on the absorber core 7 along the CD direction. One of the drainage grooves 8, which is located away from the tail end of the absorber core 7, is located on the center line of the absorber core 7 along the CD direction. The other two drainage grooves 8, which are located near the tail end of the absorber core 7, can be symmetrically distributed about the center line of the absorber core 7 along the CD direction. These two drainage grooves 8 can also be symmetrically distributed about the center line of the absorber core 7 perpendicular to the CD direction.
[0047] Example 4, such as Figure 6 As shown, four drainage grooves 8 are provided on the absorber core 7 along the CD direction. Two of the drainage grooves 8, namely the front drainage groove and the rear drainage groove, are provided on the center line of the absorber core 7 along the CD direction. The other two drainage grooves 8 are intermediate drainage grooves, which are provided between the front drainage groove and the rear drainage groove. The two intermediate drainage grooves can be symmetrically distributed about the center line of the absorber core 7 along the CD direction, or they can be symmetrically distributed about the center line of the absorber core 7 perpendicular to the CD direction. The front drainage groove and the rear drainage groove can also be symmetrically distributed about the center line of the absorber core 7 perpendicular to the CD direction.
[0048] Example 5, such as Figure 7 As shown, five drainage grooves 8 are arranged along the CD direction on the absorber core 7. Two of the drainage grooves 8 are intermediate drainage grooves, which are located between the front drainage groove and the rear drainage groove. The two intermediate drainage grooves can be symmetrically distributed about the center line of the absorber core 7 along the CD direction, or they can be symmetrically distributed about the center line of the absorber core 7 perpendicular to the CD direction. There is a drainage groove 8 on the front side of the intermediate drainage groove, which is the front drainage groove. There are two drainage grooves on the rear side of the intermediate drainage groove, which are both rear drainage grooves. Both the front drainage groove and the rear drainage groove are located on the center line of the absorber core 7 along the CD direction.
[0049] Example 6, such as Figure 8 As shown, six drainage grooves 8 are arranged along the CD direction on the absorber core 7. The drainage grooves 8 are arranged in pairs, forming three groups of drainage grooves arranged in parallel along the CD direction. Two drainage grooves in the middle group are located on the center line of the absorber core 7 along the CD direction. The two outer groups of drainage grooves can be symmetrically distributed about the center line of the absorber core 7 along the CD direction. The drainage grooves 8 near the tail end of the absorber core 7 in the three groups of drainage grooves can also be symmetrically distributed about the center line of the absorber core 7 perpendicular to the CD direction.
[0050] The aforementioned drainage groove 8 helps to change the direction of liquid diffusion and can also break the lateral rigidity of the absorbent core 7, thereby enhancing groin comfort.
[0051] The above-mentioned crotch absorbent sheet 2 can be provided with a fourth elastic band 10 on both sides of the absorbent core 7 in a direction perpendicular to the CD direction. The fourth elastic band 10 is set in accordance with the drainage groove 8. The fourth elastic band 10 plays a role in lifting the crotch so as to better and timely drain unabsorbable excrement or menstrual blood and reduce the occurrence of side leakage.
[0052] One or more third elastic bands 6 can be added between the two layers of non-woven fabric 3. The third elastic bands 6 are positioned to correspond to the buttocks of the human body, and the third elastic bands 6 can also be symmetrically arranged about the center line of the absorbent core 7. The addition of the third elastic bands 6 can enhance the fit of the disposable trouser-style absorbent product to the buttocks when worn.
[0053] The tail end of the aforementioned absorbent core 7 can be provided with an opening 9 corresponding to the adjustment part. The position of the opening 9 corresponds to the position of the groin of the human body. The opening 9 may include opening portions located on both sides of the center line of the absorbent core 7, and these two opening portions are symmetrically distributed about the center line of the absorbent core 7. The opening 9 is V-shaped. The design of the opening 9, combined with the third elastic band 6, can achieve the purpose of adjusting the opening angle of the opening 9 in a direction perpendicular to the CD direction. In addition, the absorbent core 7 in the groin area can achieve the purpose of adjusting the opening angle of the opening 9 according to the change of the human body curve through the first elastic band 4.
[0054] The aforementioned undisclosed matters can be directly implemented using existing technologies, so they will not be elaborated upon here.
