The urine absorption core is provided on the bottom layer of the diaper. In the prior art, the mixture is mixed with wood pulp and water absorbing resin and then coated with wet strong paper. Although the core body has good water absorption and large water absorption, when a certain part of the core body absorbs water, the weight is large, and during the movement of the user, the generated vibration causes the water absorbing portion to break with other dry portions, so that it is easy to crepe. Moreover, the gas permeability after mixing of the wood pulp and the water absorbing resin and the gas permeability of the wet strength paper are both poor, so that the product having such a structure is inferior in gas permeability.

A fluffy nonwoven fabric layer, a polymer water absorbing resin layer, and a spunlace layer.
蓬松无纺布层的无纺布克重为38～45克/平方米。The non-woven fabric of the fluffy nonwoven fabric has a basis weight of 38 to 45 g/m 2 .
所述蓬松无纺布层的厚度为4～8毫米。The bulky nonwoven fabric layer has a thickness of 4 to 8 mm.
所述高分子吸水树脂层的吸水树脂颗粒粒径为50～100目。 The water absorbing resin particles of the polymer water absorbing resin layer have a particle diameter of 50 to 100 mesh.
所述表层为珍珠面料。The surface layer is a pearl fabric.
所述导流层为热风无纺布。The flow guiding layer is an air-through nonwoven fabric.
本实用新型的有益效果：The beneficial effects of the utility model:
与现有技术相比，本实用新型的纸尿裤芯体结构从内向外依次为蓬松无纺布层、高分子吸水树脂层和水刺布层，蓬松无纺布层位于芯体中心，其作用有三，一是增加纸尿裤整体的舒适性，二是可以利用蓬松无纺布层的无纺布表面的疏松孔隙来固定位于其两面的高分子吸水树脂颗粒，防止高分子吸水树脂层断裂，三是其液体的下渗速度好，从芯体前表面下渗的液体可以快速从蓬松无纺布层前表面的高分子吸水树脂层下渗到蓬松无纺布层后表面的高分子吸水树脂层。水刺布层的透气性好，又能够增加芯体的整体强度，防止高分子吸水树脂层的断裂，从而使得芯体不会起坨。Compared with the prior art, the diaper core structure of the utility model has a fluffy non-woven fabric layer, a polymer water absorbing resin layer and a spunlace layer from the inside to the outside, and the fluffy non-woven fabric layer is located at the center of the core body, and has three functions. One is to increase the overall comfort of the diaper, and the other is to use the loose pores on the surface of the non-woven fabric of the fluffy non-woven fabric layer to fix the polymer water absorbing resin particles on both sides thereof to prevent the polymer water absorbing resin layer from being broken, and the third is The liquid infiltration rate is good, and the liquid which is infiltrated from the front surface of the core can be quickly infiltrated from the polymer water-absorbent resin layer on the front surface of the bulky nonwoven fabric layer to the polymer water-absorbent resin layer on the rear surface of the bulky nonwoven fabric layer. The spunlace layer has good gas permeability, and can increase the overall strength of the core body to prevent breakage of the polymer water absorbing resin layer, so that the core body does not crease.
