Toilet article absorbing core and production technology thereof

Abstract

The invention discloses a toilet article absorbing core and a production technology thereof. The toilet article absorbing core comprises an upper wrapping layer, absorbing core layers, a lower wrapping layer and a first gluing set which is used for allowing the upper wrapping layer to be glued with the lower wrapping layer, and the absorbing core layers include a first absorbing core layer, a first fiber layer and a second absorbing core layer which are arranged sequentially from top to bottom; the first gluing set includes at least two sets of first gluing bodies which are alternatively arranged along the length direction of the absorbing core, the first gluing bodies are matched with the absorbing core in width and divide the absorbing core into at least three sections from the length direction, and the absorbing core layers between the front section and the rear section further include a third absorbing core layer and a second fiber layer which are sequentially arranged between the first fiber layer and the second absorbing core layer from top to bottom.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to an absorbent core of an absorbent product and a manufacturing process thereof. Background technique [0002] Absorbent articles such as paper diapers and sanitary napkins are commonly used sanitary products. Generally, such absorbent articles consist of three main parts: a surface cover, an absorbent core, and a base fabric. The surface coating layer can also be called a coating layer or a water-permeable surface layer. The coating layer is close to the user's body, which can promote the rapid penetration of urine and effectively prevent back seepage, so that the surface layer of the diaper can be kept dry. At present, the covering layer of diapers in the domestic market is basically a non-woven surface layer. The breathable non-woven fabric can improve the air permeability inside the diaper, and the water vapor can circulate outside the diaper, and the moisture and heat can be ...

Problems solved by technology

[0004] In these methods, the composition of the absorbent core still adopts the traditional upper and lower wrapping layers, the absorbent core layer between the upper and lower wrapping layers, and the upper viscose for bonding the absorbent core layer and the upper wrapping layer. layer, the lower viscose layer for bonding the absorbent core layer and the lower wrapping layer, while the absorbent core layer is still composed of the middle fluffy non-woven fabric layer and the upper polymer water-absorbing layer respectively located on the upper and lower surfaces of the middle fluffy non-woven fabric layer. The resin layer and the lower polymer water-absorbing resin layer are composed. In this way, the entire absorbent core has seven layers, and the two layers of viscose layer adopt the full spray method, which increases the thickness of the entire absorbent core and is not conducive to the absorption of the absorbent core. Similarly, the fluffy non-woven fabric layer also increases the thickness, but the diffusion and absorption effects are not good; and, the existing polymer water-absorbing resin layer has the same thickness on the entire core body, so that the front and rear sides of the absorbent core body have the same thickness. The utilization rate of the polymer water-absorbent resin in the middle section of the absorbent core is low, and the polymer water-absorbent resin located in the middle section of the absorbent core (urine point) is overutilized, resulting in poor diffusivity in the middle section
