Embodiment Construction

[0029] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0030] refer to Figure 1 to Figure 5 , the present embodiment provides a diaper core manufacturing process, comprising the following steps:

[0031] (1) Manufacture of the first core layer: the bottom non-woven fabric 1 is transported to the first mold wheel, the outer edge of the first mold wheel is provided with an adsorption template, and the adsorption template is provided with a positive integer number of modules, polymer materials Sprinkle on the first mold wheel, the module on the first mold wheel has negative pressure, and the bottom non-woven fabric 1 enters the mold wheel adsorption plate before the polymer material is sprinkled on the first mold wheel, and the module will be absorbed by the adsorption force. The polymer material is adsorbed and adhered to the bottom non-woven fabric, and the polymer material on each module forms a first ...

Abstract

The invention relates to a paper diaper core manufacturing process. The paper diaper core manufacturing process comprises the following steps of: (1) manufacturing a first core layer; (2) compounding an upper-layer non-woven fabric; (3) carrying out first-time lamination; (4) manufacturing a second core layer; and (5) carrying out second-time lamination. The invention relates to the field of disposable sanitary products; a core adopts a double-layered core; compared with a traditional water absorption paper core, the second core made of wood pulp is good for improving the diffusion length and diffusion speed of urine and the problem that the urine is concentrated in the middle to be absorbed and is not diffused front and back is solved; the utilization rate of the core is improved; meanwhile, the first core at the lower layer is used for fixing macromolecules into grids so that the utilization of fluffy non-woven fabrics in the traditional water absorption paper core and upper-layer and lower-layer dust-free paper is reduced; the thickness of the core is effectively reduced and the absorption amount of a product is kept; and the technical problems that the core difficultly keeps the thinness of the product and the diffusion and absorption of the product also can be improved are solved.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a manufacturing process of a diaper core body. Background technique [0002] At present, there are mainly three types of existing core structures, one is the traditional wood pulp and polymer core, the other is the absorbent paper core, and the third is the absorbent paper core + the traditional wood pulp polymer core. All have obvious flaws. Core 1, because wood pulp and polymers need to be mixed, so more wood pulp is added to make the product thicker, and it is easy to agglomerate and break after use; core 2, the product is thinner, but because the material used for the core is non-woven Cloth or dust-free paper, the diffusion of this material is not as good as wood pulp, and due to the characteristics of the process, more polymers are distributed on the fluffy non-woven fabric, after absorbing liquid, it is prone to gel clogging, which will affect the urine Absorp...
