Description

Technical Field

[0001] The utility model belongs to the technical field of baby appliances, and in particular relates to a pipeline type diaper. Background Art

[0002] The core is the key factor that determines the performance of diapers, and there are many factors that affect the performance of the core, such as the performance of the absorbent material, the core structure and the density of the liquid absorption layer. If the core structure is not set reasonably, the liquid absorption rate will be greatly reduced, and in severe cases, back-seepage may occur. In order to further improve the absorption performance of the core, this solution was created. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a pipe-type diaper, whose absorption core layer has a better absorption effect.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a tube-type diaper, including a diaper body, the diaper body including a surface coating layer, an absorbent core layer and a bottom layer, the absorbent core layer including an upper non-woven fabric layer, a plurality of kapok strips, a fluffy non-woven fabric layer, a polymer water-absorbent resin and a lower non-woven fabric layer, the upper non-woven fabric layer, a plurality of kapok strips, a fluffy non-woven fabric layer and a lower non-woven fabric layer are arranged in sequence from top to bottom, the polymer water-absorbent resin is distributed in the fluffy non-woven fabric layer, and a plurality of the kapok strips are arranged at intervals along the width direction of the non-woven fabric layer.

[0005] Furthermore, the vertical cross-section of the kapok strip is elliptical.

[0006] Furthermore, the amount of the high molecular water-absorbing resin in the fluffy non-woven fabric increases from both sides toward the middle of the fluffy non-woven fabric.

[0007] Furthermore, a plurality of first guide grooves are arranged on the surface of the surface coating layer, both sides of the first guide grooves are tapered, and both sides of the plurality of first guide grooves are connected.

[0008] Furthermore, there are long strip-shaped second guide grooves on both sides of the first guide groove.

[0009] Furthermore, waist connecting belts are provided on both sides of the two ends of the surface coating layer.

[0010] Furthermore, tightening belts are provided on both sides of the surface coating layer.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The absorbent core layer of the diaper body in the utility model is composed of an upper non-woven fabric layer, a plurality of kapok strips, a fluffy non-woven fabric layer, a polymer water-absorbing resin and a lower non-woven fabric layer, wherein the plurality of kapok strips are located between the upper non-woven fabric layer and the fluffy non-woven fabric layer and are arranged at intervals. With the arrangement of the kapok strips, when absorbing water, the kapok strips absorb it first and then quickly conduct it to the fluffy non-woven fabric layer. When the amount of water is large, due to the height difference between the kapok strips located below and the fluffy non-woven fabric layer, under the action of gravity, the water will quickly enter the gaps between the plurality of kapok strips and then disperse and flow into the fluffy non-woven fabric layer, so that the water absorption efficiency is higher and faster.

[0017] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0018] like Figure 1-Figure 3 As shown, this embodiment provides a pipe-type diaper, including a diaper body 1.

[0019] The diaper body 1 includes a surface coating layer, an absorbent core layer and a bottom layer. The absorbent core layer includes an upper non-woven fabric layer 15, a plurality of kapok strips 16, a fluffy non-woven fabric layer 17, a polymer water-absorbent resin 18 and a lower non-woven fabric layer 19. The upper non-woven fabric layer 15, the plurality of kapok strips 16, the fluffy non-woven fabric layer 17 and the lower non-woven fabric layer 19 are arranged in sequence from top to bottom. The polymer water-absorbent resin 18 is distributed in the fluffy non-woven fabric layer 17. The number of polymer water-absorbent resins 18 located in the fluffy non-woven fabric increases from both sides of the fluffy non-woven fabric toward the middle. Under the action of gravity, water will flow to the bottom of the diaper body 1, so more polymer water-absorbent resins 18 are arranged in the middle of the fluffy non-woven fabric (that is, the bottom of the diaper body 1), and the water absorption effect will be better. A plurality of kapok strips 16 are arranged at intervals along the width direction of the non-woven fabric layer. Specifically, the vertical cross-section of the kapok strips 16 is elliptical. Under the same volume, the contact area of ​​the elliptical kapok strips 16 placed flat is larger than that of the circular kapok strips 16.

[0020] With the arrangement of the kapok strips 16, when absorbing water, the kapok strips 16 absorb it first and then quickly conduct it to the fluffy non-woven fabric layer 17. When the amount of water is large, due to the height difference between the kapok strips 16 located below and the fluffy non-woven fabric layer 17, under the action of gravity, the water will quickly enter the gaps between the multiple kapok strips 16 and then disperse and flow into the fluffy non-woven fabric layer 17, making the water absorption efficiency higher and faster. Moreover, during absorption, the fluffy non-woven fabric layer 17 without the kapok strips 16 has low water conduction efficiency, and it is easy to concentrate water in a certain area, which finally causes seepage. With the arrangement of the kapok strips 16, since the kapok strips 16 have better water conduction, the kapok strips 16 first absorb water and then evenly diffuse it to the fluffy non-woven fabric layer 17. Such an arrangement can avoid the backseepage phenomenon.

[0021] Waist connecting belts 13 are arranged on both sides of both ends of the surface covering layer, and tightening belts 14 are arranged on both sides of the surface covering layer. A plurality of first guide grooves 11 are arranged on the surface of the surface covering layer, and the first guide grooves 11 are tapered on both sides, and the two sides of the plurality of first guide grooves 11 are connected, and the first guide grooves 11 are provided with long strips of second guide grooves 12 on both sides. The first guide grooves 11 and the second guide grooves 12 are arranged so that there is a gap between the surface covering layer and the human body, so that water can be guided to the lowest point of the surface covering layer for water absorption more quickly.

[0022] The above shows and describes the basic principles and main features of the invention and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the invention, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be defined by the attached claims and their equivalents.
