Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of disposable absorbent cores, in particular to a diaper absorbent core using a composite water-absorbing polymer. Background Art
[0002] Infant diapers absorb urine through the absorbent core. The absorbent core is soft as a whole. When it is compounded with the surface and bottom layers of the diaper, it is difficult to press out diversion grooves directly on the surface layer and the absorbent core. The liquid cannot be diverted away on the surface of the absorbent core and can only be absorbed by infiltration. During the infiltration process, it will soak the buttocks, making the baby prone to problems such as red buttocks, affecting the feeling of use.
[0003] Therefore, in order to improve the diversion and absorption effect of the absorbent core to avoid red buttocks, this case was created. Utility Model Content
[0004] Therefore, in view of the above problems, the present invention proposes a diaper absorbent core using a composite water-absorbing polymer, which has a reasonable structural design, good diversion and absorption effects and can prevent red buttocks.
[0005] In order to solve the above technical problems, the solution adopted by the utility model is: a diaper absorbent core using a composite water-absorbent polymer, including a first absorbent layer and a second absorbent layer, the second absorbent layer is compositely arranged in the middle of the upper surface of the first absorbent layer, the left and right sides of the first absorbent layer are folded toward the upper surface of the first absorbent layer, and guide grooves extending in the front-to-back direction are respectively formed between the left and right sides of the first absorbent layer and the left and right sides of the second absorbent layer.
[0006] A further improvement is that a quick-absorbing layer for quickly absorbing liquid in the guide groove is arranged between the upper surface of the first absorption layer and the lower surface of the second absorption layer, the width of the quick-absorbing layer is greater than the width of the second absorption layer, the left and right sides of the first absorption layer are folded toward the upper surface of the quick-absorbing layer, and the left and right sides of the first absorption layer and the left and right sides of the second absorption layer form a quick-absorbing guide groove with the quick-absorbing layer as the bottom.
[0007] A further improvement is that the left and right sides of the quick-absorbing layer are folded toward the upper surface of the quick-absorbing layer to form a folded portion, the left and right sides of the first absorbent layer are folded upward to the upper surface of the folded portion, and the outer groove wall of the quick-absorbing guide groove is higher than the inner groove wall.
[0008] A further improvement is that the quick-absorbing layer is made of pure cotton.
[0009] A further improvement is that the second absorption layer includes a second upper liquid absorption layer, a second composite water-absorbing polymer layer with fragrance and / or color, and a second lower liquid absorption layer.
[0010] A further improvement is that the second composite water-absorbing polymer layer is made by mixing one or more of tea polyphenol powder, wormwood powder, green tea powder, lithospermum powder, camellia seed powder and essence in any ratio and then mixing with water-absorbing polymer particles.
[0011] A further improvement is that the second upper liquid-absorbent layer and the second lower liquid-absorbent layer are non-cotton non-woven fabrics.
[0012] A further improvement is that the first absorption layer includes a first upper liquid-absorbing layer, a polymer layer or a first composite water-absorbing polymer layer with fragrance and / or color, and a first lower liquid-absorbing layer.
[0013] A further improvement is that the polymer layer is a water-absorbing polymer particle layer.
[0014] A further improvement is that: the first upper liquid-absorbent layer and the first lower liquid-absorbent layer are non-cotton non-woven fabrics.
[0015] By adopting the above technical solution, the beneficial effects of the utility model are:
[0016] In this case, two integrated guide grooves are formed on the absorbent core through the composite structure of the second absorbent layer and the first absorbent layer and the folded structure of the first absorbent layer. The guide grooves are beneficial for front and rear flow guidance to increase the absorption speed of the absorbent core. At the same time, the bottom of the guide groove is lower than the surface layer of the absorbent core, which can prevent liquid from staying on the surface layer of the absorbent core and prevent the baby from having a red butt.
[0017] A further beneficial effect is that a quick-absorbing layer made of pure cotton is arranged between the first absorption layer and the second absorption layer. The quick-absorbing guide groove formed by the quick-absorbing layer and the guide groove improves the liquid diversion and absorption efficiency. At the same time, the absorption efficiency of the quick-absorbing layer is faster than that of the lower liquid-absorbing layer of the first absorption layer and the upper liquid-absorbing layer of the second absorption layer, so that the quick-absorbing layer absorbs the liquid first and penetrates into the first absorption layer and the second absorption layer, thereby absorbing the liquid from the inside to the outside, so as to keep the surface layer of the diaper dry and breathable, and improve the use experience of the diaper.
[0018] A further beneficial effect is that the left and right sides of the quick-absorption layer are folded upward to form a folded portion, which increases the height of the left and right sides of the first absorption layer, so that the outer groove wall of the quick-absorption guide groove is higher than the inner groove wall, which is beneficial to blocking the liquid from flowing laterally along the upper surface of the absorption core to the two sides of the absorption core, effectively avoiding side leakage.
[0019] A further beneficial effect is that the second composite water-absorbent polymer and / or the first composite water-absorbent polymer layer is made of one or more of tea polyphenol powder, wormwood powder, green tea powder, lithospermum powder, camellia seed powder, and essence, which are mixed in any ratio and then mixed with water-absorbent polymer particles. The aroma of tea polyphenol powder, wormwood powder, green grass powder, and essence covers the urine smell of the diaper, so that the diaper always keeps a fresh fragrance; lithospermum powder and camellia seed powder can inhibit inflammation and help recover from diaper rash. At the same time, the colors of these powders are attached to the water-absorbent polymer particles, so that the absorbent core can show color after absorbing urine. BRIEF DESCRIPTION OF THE DRAWINGS
