Description

Technical Field

[0001] This utility model relates to the field of diaper technology, specifically to a diaper with good absorbency. Background Technology

[0002] Disposable diapers are an essential item in modern childcare and occupy an important position in the field of infant care. As living standards improve, parents have increasingly stringent requirements for the performance of disposable diapers, with absorbency becoming one of the key indicators for measuring diaper quality.

[0003] Traditional disposable diapers' absorbent core is primarily composed of a layered structure made of pure wood pulp (fluff pulp) and superabsorbent polymer (SAP). The fluff pulp is responsible for initially dispersing urine, while SAP, with its superior absorbency, can absorb liquids tens or even hundreds of times its own weight. However, in actual use, due to the physiological structure of the human body and the characteristics of urine distribution, urine cannot quickly and evenly spread throughout the entire absorbent core. This causes some areas of SAP to fail to come into timely contact with urine, delaying absorption and leading to urine accumulation on the diaper surface, significantly impacting the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a diaper with good absorbency, which has the advantage of quickly absorbing urine and solves the problem that current diapers cannot quickly guide urine according to the physiological structure of the human body during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diaper with good absorbency, comprising a pant body, a waistband at the top of the pant body, two symmetrically arranged pant legs at the bottom, and a crotch connected to the two pant legs at the middle of the bottom of the pant body. The crotch includes a distribution layer, and two leak-proof parts are symmetrically arranged on the upper edge of the distribution layer. A separator is connected to the middle of the two leak-proof parts, and the separator is located at the middle of the upper surface of the distribution layer.

[0006] Preferably, the waistband is provided with an elastic belt.

[0007] Preferably, the inside of the trouser leg is provided with an elastic belt, and the elastic value of the elastic belt inside the trouser leg is less than the elastic value of the elastic belt inside the waistband.

[0008] Preferably, each of the leak-proof parts has an adhesive part on the outer side of its upper end face and a blocking part on the inner side of its upper end face. The adhesive part and the blocking part are side-fitted together, and the top of the connection between the adhesive part and the blocking part extends out of the upper end face of the guide layer.

[0009] Preferably, the outer edges of both the fitting portion and the blocking portion are arc-shaped, and the curvature value of the fitting portion is smaller than that of the blocking portion.

[0010] Preferably, the flow guiding layer has a core inside, and the core adopts a multi-layer composite design, with the uppermost layer being a rapid flow guiding layer, the middle layer being a high-efficiency absorption layer, and the bottom layer being a water-locking and seepage-proof layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting a crotch, a leak-proof part, a partition part, a fitting part, and a blocking part, divides the upper surface of the guide layer into two areas by setting the leak-proof part at the edge of the upper surface and the partition part in the middle. The front area is designed to address the characteristic that urine concentrates at the front during urination, while the rear area focuses on preventing fecal leakage. The leak-proof part and partition part protruding from the outer edge of the guide layer, and the fitting part and blocking part on the outer edge of the leak-proof part, can effectively prevent side leakage and back leakage.

[0013] 2. This utility model features a core with a multi-layered structure. The top layer is a rapid-flow guiding layer made of a special high-flow-conductivity non-woven fabric. The fibers undergo special treatment, resulting in hydrophilic microgrooves on the surface. When urine comes into contact with this layer, the microgrooves act like tiny channels, rapidly guiding the urine outwards and diffusing it throughout the entire upper layer of the core, significantly increasing the initial absorption rate and preventing urine accumulation on the surface. The middle layer is a high-efficiency absorbent layer, scientifically mixing superabsorbent polymer (SAP) with fluffy, highly absorbent lint-free paper. Through a special pressing process, the SAP is evenly distributed within the fiber gaps of the lint-free paper, increasing the contact area between the SAP and urine. This ensures that the SAP can fully utilize its powerful absorbency during absorption, effectively increasing the absorption capacity. The bottom layer is a water-locking and seepage-proof layer made of a highly tough and waterproof film material with micron-sized breathable pores evenly distributed on its surface. This layer not only locks in the urine absorbed by the middle layer to prevent backflow, but also allows moisture to escape through the vents, keeping the inside of the diaper dry without affecting the overall leak-proof performance.
