Detailed Description
The present invention will be described in further detail with reference to embodiments.
As shown in fig. 1, a method for manufacturing a diaper core comprises the following steps: 1) the main body part of the core body is made of fluffy cotton, and high polymers are distributed on the upper surface of the core body in a sprinkling manner; 2) the fluffy cotton core body is placed on the first hydrophilic non-woven fabric, the second hydrophilic non-woven fabric is laid on the upper surface of the fluffy cotton core body, and the peripheries of the first hydrophilic non-woven fabric and the second hydrophilic non-woven fabric are sealed in a hot pressing mode; 3) and performing partition treatment on the sealed and hot-pressed core body to preset partition lines, and injecting hot melt adhesive into the core body by using pinhole type hot-pressing equipment according to the partition lines. When the pinhole type hot-pressing equipment injects the hot melt adhesive into the core body, the hot melt adhesive can be bonded between the first hydrophilic non-woven fabric and the second hydrophilic non-woven fabric, and then the pinhole type hot-pressing equipment sequentially injects the hot melt adhesive into the core body along the partition line for bonding. The most important part of the production method is to manufacture the core body in a subarea mode, hot melt adhesive of the pin-hole type hot-pressing equipment flows out of the pin holes according to the designed subarea lines, the pin holes are sequentially injected with glue on the core body along the designed subarea lines, the hot melt adhesive is quickly solidified, so that no extra equipment or time is needed for cooling the hot melt adhesive, the pin holes are pricked into the first hydrophilic non-woven fabric and then flow out of a small amount of hot melt adhesive, the hot melt adhesive is arranged between the first hydrophilic non-woven fabric and the second hydrophilic non-woven fabric, downward pressure is given to the first hydrophilic non-woven fabric when the pin holes are pricked, the hot melt adhesive flowing out of the pin holes can quickly bond the first hydrophilic non-woven fabric and the second hydrophilic non-woven fabric, the operation of the pin.
In one embodiment, the amount of the polymer in the middle of the fluffy cotton core in the step 1) is 1.5-3 times of that in the two end parts. In the using process of the paper diaper, the part which absorbs body fluid most is the middle part, and after the paper diaper is divided, polymers between all the regions are stable, so that the polymer consumption of the middle part of the fluffy cotton core body is more than that of the two end parts.
In one embodiment, the first hydrophilic non-woven fabric and the second hydrophilic non-woven fabric in the step 2) have the same size, the fluffy cotton core body is clamped between the first hydrophilic non-woven fabric and the second hydrophilic non-woven fabric, and the first hydrophilic non-woven fabric and the second hydrophilic non-woven fabric are pressed at the periphery. The fluffy cotton core body is clamped between the first hydrophilic non-woven fabric and the second hydrophilic non-woven fabric so as to partition the core body conveniently,
in one embodiment, the core is divided into four parts, namely a front part, a rear part and a left part and a right part by the partition lines in the step 3), a central line 1 which divides the core into a left area 2 and a right area 3 is arranged in the middle part of the core along the longitudinal direction, the front end of the central line 1 extends obliquely forwards and towards two sides to the edge of the core to form the front area 2 of the core, and the rear end of the central line 1 extends obliquely rearwards and towards two sides to the edge of the core to form the rear area 3 of the. When the paper diaper is used, the middle part of the diaper usually sinks downwards, the middle part of the core body can be conveniently downwards arranged by the aid of the central line 1, and accordingly, the generation of the loop legs of a baby in the using process can be avoided.
In one embodiment, the left region 4 and the right region 5 of the core are symmetrical and the front region 2 and the back region 3 of the core are symmetrical. The division of the core into regions is designed according to the baby's anatomy, which is usually symmetrical, so that the left region 4 and the right region 5 of the core are symmetrical, and the front region 2 and the rear region 3 are symmetrical, in order to increase the comfort of the baby in use; simultaneously, the design of symmetry makes the inside atress everywhere of core even, avoids because regional distribution is uneven, can rise the problem of the fault that sticks together in the core use.
The paper diaper core comprises a front area 2, a rear area 3, a left area 4 and a right area 5, wherein the front area and the rear area are symmetrical, and the left area and the right area are symmetrical. Panty-shape diapers have certain thickness and width usually, and the main part is exactly the panty-shape diapers core, therefore the baby can make baby's both legs be difficult to close up in the use panty-shape diapers, long this baby produces the locular ring leg easily in the past, when using the panty-shape diapers of this technical scheme panty-shape diapers core, when baby's both legs will close up, the core receives the pressure on both sides and can extrude toward the centre, and set up central line 1 in the centre and be favorable to panty-shape diapers mid portion undercut, therefore baby closes up both legs easily, it can be more comfortable to use, can avoid the production of baby's locular ring leg. In addition, when the legs of the baby move, the thigh roots are difficult to avoid long-term friction with the paper diaper, so that the baby often feels red and swollen, and in the use process of the paper diaper made of the core body in the technical scheme, the paper diaper can be bent along the body of the baby by the boundary of the front area 2, the left area 4 and the right area 5, so that the thigh roots of the baby and the paper diaper can be avoided from friction to a great extent. Therefore, the core that this technical scheme designed accords with the anthropology, and according to the panty-shape diapers core of human morphological design department reasonable shape, the baby can reach in the use and avoid the broken problem that the leg is enclosed to the ring, the health is red and swollen, the core rises to stick together.
The above description is only one specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any changes or modifications within the field of the present invention by those skilled in the art are covered within the scope of the present invention.
