Description
Technical Field
The invention relates to the technical field of absorbent articles, in particular to an ultrathin composite structure capable of automatically and directionally transferring urine wet and a paper diaper.
Background
Paper diapers are one of the most common articles for daily use, and are nursing products designed for infants, middle-aged and elderly people and patients. The paper diaper can absorb urine excreta of a user, keep dry and comfortable, further improve sleep quality and reduce the burden of nursing staff. Due to the characteristics of convenience and quickness of the paper diaper, the demand and the application range of the paper diaper are increasingly enlarged. For the conventional diaper, urine is generally penetrated downward in a vertical direction and absorbed by the absorbent core, in other words, urine is penetrated downward from the surface layer of the diaper near the skin to the absorbent core and absorbed. In addition, in order to make the liquid better reach the absorbent core, the non-woven fabric of the surface layer is mostly a non-woven fabric with hydrophilic property; however, the hydrophilic non-woven fabrics can cause the skin to contact the surface layer to still feel moist after urine is absorbed; and the existing paper diapers can also generate the phenomenon of urine reverse osmosis after being used for a plurality of times.
Although some technologies have been proposed to use a hydrophobic material on the side close to the skin and design some special structures to solve the problems of the diaper, there is still a risk that urine is excessively accumulated and rewet to the skin-friendly side. In addition, since the volume of the absorbent core on the middle side of the crotch portion expands after absorbing water, wearing comfort is directly affected, and thus, in addition to the above-mentioned drawbacks, there is a need for improvement in wearing comfort of conventional diapers.
There is a need in the art for an absorbent structure or diaper that can be applied to diapers to solve the deficiencies of prior art diapers.
Disclosure of Invention
The invention aims to overcome at least one defect of the prior art, provides an ultrathin composite structure capable of automatically and directionally transferring urine to wet and a diaper, and solves the problems of poor comfort and easiness in reverse osmosis in the using process of the absorbent article in the prior art.
An object of the present invention is to provide an ultra-thin composite structure for automatically and directionally transferring urine wet, namely a rapid directional liquid diffusion composite structure, comprising a liquid conducting structure, an absorption aggregate and a liquid suppressing structure; the absorption assembly is arranged at the end part of the liquid conducting structure; the liquid conducting structure is connected with the absorption assembly; and the surface of the absorption aggregate is provided with a liquid separation structure; the liquid suppressing structure is arranged beside the liquid conducting structure. Further, both ends of the liquid conducting structure are connected with the absorption aggregate. The liquid conducting structure is provided with a long side and a short side, the absorption assembly is arranged at the short side end, and the liquid suppressing structure is arranged beside the long side. The liquid conducting structure receives liquid and leads to the absorption assembly at the end part, and the liquid restraining structure restrains the liquid received by the liquid conducting structure from flowing to the side of the liquid conducting structure.
When the liquid conducting structure receives liquid, the liquid is laterally diffused towards the two ends along the liquid conducting structure, and the liquid cannot be diffused in the lateral direction of the liquid conducting structure under the action of the lateral liquid inhibiting structure. The absorption assembly is positioned at the end part of the liquid conduction structure and connected with the liquid conduction structure, so that liquid conducted along the liquid conduction structure can be rapidly absorbed. Meanwhile, the liquid separation structure on the absorption combination body can isolate the liquid absorbed by the absorption combination body from contacting with the skin of a human body, so that the reverse osmosis of the liquid is prevented. Compared with the traditional mode of absorbing from skin-friendly surface layer infiltration to the absorption core body, the liquid conducting structure and the absorption assembly which are horizontally arranged in the unfolding state are configured, liquid is concentrated at two ends for absorption instead of the middle side, the liquid separating structure is matched, the moist feeling and common reverse osmosis problem of the skin-friendly surface of the middle side are effectively avoided, and the wearing comfort is remarkably improved.
The ultrathin composite structure capable of automatically and directionally transferring urine wet can be applied to absorbent articles including paper diapers, and particularly can thoroughly solve the problem of reverse osmosis after urine absorption saturation when the ultrathin composite structure is applied to paper diapers. Compared with the prior art, the absorption core is located below the urination and defecation region, the condition that urine is reversely oozed exists when urine is absorbed, skin discomfort is easy to cause, skin health is affected and the like, in the application, urine is conducted through the liquid conduction structure to enable the absorption assembly to be absorbed, the absorption assembly is configured at two ends of the urination and defecation region in the same plane direction, and meanwhile, the liquid separation structure is arranged on the absorption assembly, so that the problem of reverse oozing of urine is effectively avoided, meanwhile, the comfort level of use is remarkably improved, and the structure is simple. Further, when the ultrathin composite structure capable of automatically and directionally transferring the urine wet is applied to a paper diaper, two ends of the liquid conducting structure are respectively connected with the front waist and the rear waist of the paper diaper. Through the arrangement of the liquid conducting structure in the length direction of the paper diaper and the liquid inhibiting structure distributed in the width direction of the paper diaper, urine can be directionally and rapidly conducted to the corresponding positions at the two ends of the liquid conducting structure; the water absorption aggregate with the liquid isolation structure, which is matched with the liquid conduction structure and is positioned on the same layer, effectively solves the problems of poor use comfort and reverse urine seepage of paper diapers in the prior art, and has a simple functional structure.
Further, the liquid conducting structure comprises a conducting strip layer which receives liquid and leads to the absorbent aggregate at the end. Further, the conducting strip layer is a single conducting strip, and the conducting strip is long. In addition, the conducting bar can also be in an hourglass shape with width shrinking from two ends to the middle.

Further, the yarn is made of a plurality of special-shaped section yarns which are arranged in parallel. The guiding direction is convenient to keep consistent, so that the liquid conduction efficiency is improved.
Further, the conducting bar layer comprises a plurality of conducting bars which are arranged in the same direction, and the conducting bars form the conducting bar layer. Besides adopting a plurality of special-shaped section yarns to manufacture a single conducting strip with larger area to form a corresponding conducting strip layer, a plurality of conducting strips with smaller area can be manufactured and matched to form a conducting strip layer with larger overall area.
Further, the conducting bar layer comprises a plurality of conducting bars which are arranged in parallel. Likewise, when the conducting strip layer is formed by a plurality of conducting strips, the conducting strips can be parallel to each other to maintain a consistent conducting direction on the conducting strip layer, so that liquid can be conducted to the end absorption assembly rapidly. Further, the conducting strip is made of a plurality of special-shaped section yarns.
Further, the conducting bars are closely adjacent to each other. The large gap between the conducting strips is avoided, the liquid is prevented from leaking downwards from the gap, and the liquid is enabled to be concentrated in the conduction in the horizontal direction.
Further, the special-shaped section yarn is made of one or more of PET fibers, PE fibers and viscose fibers. Furthermore, the special-shaped section yarn is a special-shaped section PET fiber yarn, namely the special-shaped section yarn made of PET fibers.
Further, the liquid suppressing structure includes a liquid suppressing layer that suppresses the liquid received by the conducting structure from flowing to the side of the conducting structure. Further, the liquid inhibition layer is made of a plurality of super-hydrophobic yarns. Further, the yarn is made of a plurality of super-hydrophobic yarns which are arranged in parallel. The liquid inhibition layer can effectively maintain that liquid is received in the liquid conduction structure and is conducted into the absorption assembly, so that the liquid is prevented from entering the side area of the liquid conduction structure, and the side of the liquid conduction structure is kept dry. The liquid inhibition layer can be made of a plurality of super-hydrophobic yarns, and when liquid has a tendency to flow sideways from the liquid conduction structure or falls on the liquid inhibition layer, the water can be prevented from entering based on the hydrophobic characteristics of the super-hydrophobic yarns at the moment, so that the liquid conduction structure can be promoted to conduct the liquid to the absorption assembly. And when the composite structure is applied to paper diapers, liquid falling on the surface of the liquid inhibition layer has a tendency to flow to the low-level liquid conduction structure, and is also beneficial to concentrating the liquid on the liquid conduction structure. Further, when the composite structure is unfolded, the projection shape of the liquid inhibition layer in the vertical direction is triangular or trapezoidal, and the bottom side of the liquid inhibition layer is positioned on one side of the liquid conducting structure. Because the liquid is mainly concentrated in the middle side of the ultrathin composite structure capable of automatically and directionally transferring urine, the bottom edge of the liquid inhibition layer is arranged close to one side of the liquid conducting structure, so that liquid inhibition can be effectively achieved in the main liquid falling area and is promoted to be concentrated on the liquid conducting structure, and meanwhile, the coverage area of the liquid inhibition layer can be reduced on one side far away from the liquid conducting structure, so that consumables and cost are reduced.
Further, the liquid-inhibiting layer includes a plurality of liquid-inhibiting bars arranged to form a superhydrophobic layer. Besides the liquid inhibition layer with a single large area is made of a plurality of super-hydrophobic yarns, a plurality of liquid inhibition strips with small areas can be made and matched to form the liquid inhibition layer with a large overall action area.
Further, the liquid-inhibiting layer includes a plurality of liquid-inhibiting strips arranged in parallel. Further, the liquid suppressing strip is elongated. The liquid inhibition strip is made of a plurality of super-hydrophobic yarns. Further, the liquid inhibition strips are arranged at intervals. The liquid inhibition strips which are arranged in parallel are beneficial to mutually matching and blocking liquid, are convenient for processing and production, and reduce processing difficulty. In addition, the liquid inhibition strip can also be an arc-shaped strip structure and the like. Further, by arranging the yarns with the special-shaped cross section of the liquid conducting structure and arranging the super-hydrophobic yarns of the liquid inhibiting structure, the liquid orientation can be promoted to be quickly conducted to the two-end absorption assemblies along the length direction of the liquid conducting structure.
Further, the length of the liquid suppressing strip is gradually reduced in a direction away from the liquid conducting structure sideways. That is, the liquid conducting structure and the liquid in the adjacent area are kept to be conducted towards the absorption assembly, and meanwhile, the unnecessary coverage area of the liquid inhibition strip is reduced, and the consumable and the cost are reduced.
