It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The invention relates to a paper diaper. For example, the diaper comprises a front waist portion and a rear waist portion interconnected to each other, and the diaper has a ring waist edge formed on each of opposite sides. For example, the waist-surrounding edge extends from the front waist edge to the rear waist edge, each waist-surrounding edge is provided with at least one leg rubber band, and the inner side of the rear waist is embedded with a profiling cotton core and a rear leakage blocking belt. For example, one end of each leg rubber band is embedded in the rear waist part and extends around one side edge of the profiling cotton core until being connected with the end part of the rear leakage blocking belt, so that the edge of the profiling cotton core in the rear waist part is forced to be arched to form a concave arc shape to fit the hip of a user.

Referring to fig. 1, a diaper includes a front waist portion 10 and a rear waist portion 20 connected to each other, wherein a ring waist edge 30 is formed on each of opposite sides of the diaper, the ring waist edge 30 extends from the edge of the front waist portion 10 to the edge of the rear waist portion 20, at least one leg rubber band 35 is disposed on each ring waist edge 30, a profiling cotton core 25 and a rear leakage blocking band 28 are embedded inside the rear waist portion 20, and one end of each leg rubber band 35 is embedded in the rear waist portion 20 and extends around one side edge of the profiling cotton core 25 until being connected to an end of the rear leakage blocking band 28, so that the edge of the profiling cotton core 25 in the rear waist portion 20 is forced to arch up to form a concave arc shape to fit the hip of a user. The at least one leg elastic 35 is attached to the side of the rear leakage barrier belt 28 remote from the front waist portion 10.

Because back hourglass fender area 28 inlays and locates the back waist 20 inboard, and the outside of back waist 20 is located to non-protruding, through embedding the one end of every shank rubber band 35 in back waist 20 and extending around a side edge of profile modeling cotton core 25, until connecting in the tip of back hourglass fender area 28, force the edge arch of the cotton core 25 of profile modeling in back waist 20 in order to form concave arc, with identical user's buttock, rationally shrink around the cotton core 25 of profile modeling, form and be similar to box-like, can control liquid completely and leak, make panty-shape diapers comparatively next to the shin, its leak protection effect is better.

For example, in order to better fit the buttocks of the user, the profiling cotton core 25 is formed with convex arc shaped edges 255 at opposite sides thereof, and the two leg elastic strings 35 extend along the two convex arc shaped edges 255, respectively. For example, the leg rubber 35 and the convex arc-shaped edge 255 are spaced apart from each other. The end of the contoured cotton core 25 remote from the rear leakage barrier belt 28 extends into the front waist portion 10. The two waist-surrounding edges 30 are both concave arc-shaped edges, and the two waist-surrounding edges 30 are positioned outside the two opposite sides of the profiling cotton core 25 and are arranged at intervals with the edge of the profiling cotton core 25. 2-8 leg rubber bands 35 are arranged on each waist-surrounding edge 30. By arranging the convex arc-shaped edge 255, the shape and the size of the profiling cotton core 25 are more consistent with the buttocks of a user, the coating range is larger, and the leakage-proof effect is better.

For example, to facilitate a snug fit of the edges of the contoured cotton core 25, the length of the rear leakage barrier 28 is perpendicular to the length of the contoured cotton core 25, and 3-25 elastic bands are provided within the rear leakage barrier 28. The edges of the rear leakage barrier belt 28 are at least partially embedded in the contoured cotton core 25. The rear leakage barrier 28 is integrally embedded in the contoured cotton core 25 with opposite ends of the rear leakage barrier 28 being located at opposite side edges of the contoured cotton core 25. In another embodiment, the edge of the rear leakage barrier 28 abuts the edge of the contoured wick 25. By at least partially embedding the rear leakage barrier belt 28 within the contoured wick 25 or otherwise abutting the contoured wick 25, the contoured wick 25 is not allowed to buckle outwardly and disengage from the user's hips, thereby providing a snug fit.

For example, the rear leakage blocking belt 28 is made of a water-repellent material. The length of the paper diaper is 800-980 mm, the width is 650 mm, the length of the rear leakage blocking belt 28 is 180-380 mm, and the width is 35-180 mm. By increasing the size of the rear leakage barrier belt 28, the leakage area can be increased.

Referring to fig. 2, a method for manufacturing a diaper includes the following steps:

in step S101, bonding the folded nonwoven fabric edges on the opposite sides of the middle nonwoven fabric to form a composite surface layer;

in step S102, bonding at least one elastic waist-surrounding nonwoven fabric to the bottom of the composite surface layer;

in step S103, the composite bottom layer, the profiling cotton core and the composite surface layer are stacked and compounded together to form the diaper.

For example, an elastic waist nonwoven fabric constituting the rear leakage barrier tape has a high magnification rubber band.

In the manufacturing method of the paper diaper, the elastic waistline non-woven fabric needs to be compounded and fixed with the non-woven fabric hems at two sides, then compounded with the middle non-woven fabric, and finally compounded with the compound surface layer, the profiling cotton core and the compound bottom layer, so that the compounding distance is long, the width of the surface layer is easily influenced when the multiplying power of rubber strings in the elastic waistline non-woven fabric is too high, and the paper diaper is easily warped. In the method for manufacturing the paper diaper in the embodiment, the middle non-woven fabric is bonded with the two side non-woven fabric folded edges, then the elastic waistline non-woven fabric is compounded, and then the composite surface layer, the profiling cotton core and the composite bottom layer are compounded, so that the elastic waistline non-woven fabric can be integrally compounded in a short time after being bonded and fixed on the composite surface layer to form the paper diaper, the rubber band is not easy to warp when the elastic multiplying power is high, and the width of the surface layer is ensured.

For example, the elastic waist nonwoven fabric may be provided on the front side of the diaper. For example, the carrier film may be sized to bond the base nonwoven fabric to form a composite base layer. The composite bottom layer is glued and bonded with the front waist tape and the leg rubber band, and then three-layer compounding is carried out.

In addition, compared with the common paper diaper, the paper diaper has a large waist rear rail (the part of the profiling cotton core in the rear waist part) and a large waist rear leakage (a rear leakage baffle belt) arranged inside. Wherein, a large waist back rail is arranged inside: has the advantages of widening the elastic width, improving the stretching ratio of the rubber band, enabling the waistline part to be more close-fitting and more comfortable and automatically adjusting the tightness. Compare traditional ring waist back shelves: due to the technical defects of equipment, the due functions of the rubber band cannot be improved, the stretching multiplying power is too high, and the equipment is not smooth to operate. The function of the built-in large waist back rail is as follows: the elastic range is lengthened, the back end of the core body (the profiling cotton core) is covered except the waist, and the core body is combined with the core body through the elasticity of the rubber band, so that the core body is in all-dimensional contact with the buttocks. Compare traditional ring waist back shelves: due to the defect of the back gear position, the core body is pushed outwards after the rubber band shrinks, and the core body cannot be fitted. The large waist back rail and the leg S rubber band are arranged in the cotton core box, so that the periphery of the large cotton core is reasonably contracted, the cotton core box is similar to a box shape, and liquid leakage can be completely controlled. Compared with the traditional ring waist short-distance contraction, the two sides of the large cotton core body are not close to the skin, the large cotton core body is open, and the large cotton core body is easy to leak laterally in use. The rear rail can be pressed into the cotton core completely or half pressed into the core (the bottom end of the core in the width direction protrudes out of the core), or directly arranged at the outer side of the core, namely the rear waist part, and the bottom ends of the leg rubber bands extend to the rear rail and are connected with the rear rail; compared with the traditional back drain part, the area of the back drain part can be increased, for example, the length of the traditional back drain is set to be 280 mm, and the length of the traditional back drain can be 360 mm.

Referring to fig. 3, a production apparatus and a production process of a diaper, wherein 1 is a material storage and supply unit: provides various raw materials required for producing adult diapers. 2, a glue spraying unit: and spraying the glue on the materials to be bonded to bond the materials together. And 3, a conveying unit: and conveying the materials, semi-finished products and finished products on the conveying belt to a required station. 4 is a tool rest unit: cutting the material into required length and shape, pressing groove patterns and the like. 5 is a material cutting unit: the material is cut into two parts along the conveying direction by a blade. 6 is a material bifurcation unit: the cut materials pass through a branching mechanism, so that the distance between the two materials reaches the required size. 7 is a material folding unit: a mechanism for folding the material into a desired shape. And 8 is a transverse change unit: changing the trend of the raw materials or the semi-finished products. And 9 is a material composite unit: several different materials are compounded together.
