Abstract

A paper diaper having water-absorbing layers for preventing front and back leakages includes a hydrophilic surface layer (1), a waterproof bottom layer (6), and a water-absorbing cotton core layer (2) arranged between the hydrophilic surface layer (1) and the waterproof bottom layer (6). Each of the two lateral sides of the paper diaper is provided with a three-dimensional shield (3) for preventing side leakage. A water-absorbing layer (4), which is directly adhered on the three-dimensional shields (3) and the hydrophilic surface layer (1), is additionally mounted on each longitudinal end of the water-absorbing cotton core layer (2). The paper diaper has obvious effect for enhancing the function of preventing front and back leakages because the water-absorbing layer (4) is additionally mounted on each longitudinal end and the width of the water-absorbing layer (4) is greater than the width of the water absorbing cotton core layer (2).

Description

说 明 书  Description
一种具有防前后漏吸水层的纸尿裤  Diaper with anti-back leakage layer
技术领域 Technical field
本发明涉及一种纸尿裤， 特别是一种防漏效果好的纸尿裤。  The present invention relates to a diaper, and more particularly to a diaper having a good leakproof effect.
背景技术 Background technique
传统的纸尿裤， 其结构大致是： 上面为一亲水面层 （一般采用亲水无纺布）， 下面 为一防水底层 （即纸尿裤的背面， 一般采用不透水的聚乙烯材料）， 中间为吸水棉芯层 (一般为绒毛浆与高吸水性树脂混合层）； 经一体裁剪压合成型， 在纸尿裤两侧边各设 有一立体护围，以防排泄物量大时从侧边漏出；另外在裤体的后端两侧设有一对魔术贴， 以便将裤体的前后端粘连起来穿戴在人体上。 传统纸尿裤的立体护围主要是防止侧漏 的， 但有时排泄物会从纸尿裤的纵向两端 （即前后端） 渗漏， 而造成衣物的污染。 发明内容  The traditional diaper has the following structure: a hydrophilic surface layer (usually a hydrophilic non-woven fabric), and a waterproof bottom layer (ie, the back of the diaper, generally impervious polyethylene material), with water absorption in the middle Cotton core layer (generally mixed layer of fluff pulp and super absorbent resin); integrated and pressed into a synthetic type, each side of the diaper is provided with a three-dimensional guard to prevent leakage from the side when the amount of excrement is large; A pair of Velcro are provided on both sides of the rear end of the body to adhere the front and rear ends of the pants body to the human body. The three-dimensional protection of the conventional diaper mainly prevents side leakage, but sometimes the excretion leaks from the longitudinal ends (ie, the front and rear ends) of the diaper, causing contamination of the laundry. Summary of the invention
本发明需解决的技术问题是： 本发明主要解决的是传统纸尿裤的前后渗漏问题。 本发明所采用的技术方案： 本发明包括亲水面层、 防水底层， 在亲水面层与防水底 层之间是吸水棉芯层， 在纸尿裤两侧各设有一防止侧漏的立体护围， 在吸水棉芯层的纵 向端加装有一片吸水层， 该片吸水层直接粘贴于两侧边立体护围及亲水面层上面。  The technical problem to be solved by the present invention is: The present invention mainly solves the problem of front and rear leakage of a conventional diaper. Technical Solution Adopted by the Invention: The invention comprises a hydrophilic surface layer and a waterproof bottom layer, wherein the hydrophilic surface layer and the waterproof bottom layer are a water absorbing cotton core layer, and each side of the diaper is provided with a three-dimensional protection surrounding for preventing side leakage. A water absorbing layer is added to the longitudinal end of the absorbent cotton core layer, and the water absorbing layer is directly pasted on the three sides of the three-dimensional protective cover and the hydrophilic surface layer.
上述吸水层可在前后两端进行加装。  The above water absorbing layer can be attached at both the front and rear ends.
吸水层的横向宽度超出吸水棉芯层的横向宽度。  The lateral width of the water absorbing layer is beyond the lateral width of the absorbent core layer.
本发明的有益效果： 本发明因为在纵向两端加装了吸水层， 并且吸水层的宽度超过 了吸水棉芯层的宽度， 对于加强纸尿裤前后端的防漏效果明显。  Advantageous Effects of Invention According to the present invention, since the water absorbing layer is added at both longitudinal ends, and the width of the water absorbing layer exceeds the width of the absorbing cotton core layer, the leakage preventing effect on the front and rear ends of the reinforced diaper is remarkable.
附图说明 DRAWINGS
图 1为本发明的结构示意图；  Figure 1 is a schematic structural view of the present invention;
图 2为本发明背面装配有弹性腰围的示意图。  Figure 2 is a schematic view of the back of the present invention with an elastic waist.
具体实施方式 detailed description
参见图 1， 本发明包括亲水面层 1、 防水底层 6 (即纸尿裤的背面）， 在亲水面层 1 与防水底层 6之间是吸水棉芯层 2 (图中虚线部分围成的区域），在纸尿裤两侧各设有一 防止侧漏的立体护围 3。 在吸水棉芯层 2的纵向端加装有一片吸水层 4， 该片吸水层 4 直接粘贴于两侧边立体护围 3及亲水面层 1的上面。该吸水层 4的横向宽度超出吸水棉 芯层 2的横向宽度，这样防漏效果更好。吸水层 4可在一端加装，也可在两端同时加装。 在此基础上， 还可在纸尿裤的纵向端装配弹性腰围 5， 弹性腰围 5直接粘贴在防水底层 上 6 (即纸尿裤的背面）， 纵向两端可同时加装。 弹性腰围加装在背面， 不受胶带安装的 约束， 拉伸效果好， 可使纸尿裤穿起来更加舒适、 贴身。 此外， 传统纸尿裤的立体护围 立面的基部是粘贴在亲水面层上， 尿液有时会沿亲水面层渗漏， 本发明可将立体护围立 面的基部直接粘贴在防水底层上， 且可将立体护围做成双层结构的， 这样防侧漏效果更 佳， 所以本发明不仅解决了前后漏问题， 也解决了侧漏问题。 Referring to Fig. 1, the present invention comprises a hydrophilic facing layer 1, a waterproof bottom layer 6 (i.e., the back side of the diaper), between the hydrophilic facing layer 1 and the waterproof backing layer 6 is a water absorbing cotton core layer 2 (the area enclosed by the broken line portion in the figure) ), a three-dimensional guard 3 for preventing side leakage is provided on each side of the diaper. A water absorbing layer 4 is attached to the longitudinal end of the absorbent cotton core layer 2, and the water absorbing layer 4 is directly adhered to the upper side of the three-dimensional guard 3 and the hydrophilic surface layer 1. The lateral width of the water absorbing layer 4 exceeds the lateral width of the absorbent core layer 2, so that the leakage preventing effect is better. The water absorbing layer 4 can be attached at one end or at both ends. On this basis, an elastic waist 5 can also be assembled at the longitudinal end of the diaper, and the elastic waist 5 is directly attached to the waterproof bottom layer 6 (ie, the back of the diaper), and the longitudinal ends can be simultaneously installed. The elastic waist is attached to the back, which is not constrained by the tape installation. The stretching effect is good, making the diaper more comfortable and fit. In addition, the base of the three-dimensional protective façade of the traditional diaper is adhered to the hydrophilic surface layer, and the urine sometimes leaks along the hydrophilic surface layer. The present invention can directly attach the base of the three-dimensional protective façade to the waterproof bottom layer. Moreover, the three-dimensional protection can be made into a double-layer structure, so that the side leakage prevention effect is better, so the invention not only solves the problem of front and rear leakage, but also solves the side leakage problem.
