Embodiment 1

[0028] refer to image 3 and Figure 4 , a preparation method of an improved composite core, comprising the following steps:

[0029] a. Convey a nonwoven fabric 1 in a continuous manner, define the conveying direction along the nonwoven fabric 1 as the longitudinal direction, and define the transverse direction along its width direction, and spray glue on the upper surface of the continuously conveyed nonwoven fabric 1 deal with;

[0030] b. Add polymer water-absorbing resin material 2 on the upper surface of the non-woven fabric 1 in step a;

[0031] c. Convey a bulky non-woven fabric 3 in a continuous manner, and spray glue on the upper surface of the bulky non-woven fabric 3, and then spray the polymer water-absorbing resin material 4 in the gap of the bulky non-woven fabric 3 Inside, the temperature of the spray gun used in the spraying of the polymer water-absorbent resin material 4 is controlled at 30°C, the air pressure is controlled at 0.5Mpa, and the depth of the ...

Embodiment 2

[0038] refer to Figure 5 , a preparation method of an improved composite core, comprising the following steps:

[0039] a. Convey a nonwoven fabric 1 in a continuous manner, define the conveying direction along the nonwoven fabric 1 as the longitudinal direction, and define the transverse direction along its width direction, and spray glue on the upper surface of the continuously conveyed nonwoven fabric 1 deal with;

[0040] b. Add polymer water-absorbing resin material 2 on the upper surface of the non-woven fabric 1 in step a;

[0041] c. Convey a bulky non-woven fabric 3 in a continuous manner, and press its lower surface with concave-convex rollers to form three parallel grooves 6 along the transverse direction, which are used in the spraying of the polymer water-absorbent resin material 4 The temperature of the spray gun is controlled at 30°C, the air pressure is controlled at 0.5Mpa, and the depth of the polymer water-absorbing resin material sprayed on the bulky non...

Abstract

The present invention relates to the field of disposable sanitary products, in particular to a method for preparing an improved composite core, which mainly solves the problems of complicated processing technology and high processing cost of the composite core in the prior art, and comprises the following steps: a, Prepare non-woven fabric; b, add polymer water-absorbing resin material on the non-woven fabric in step a; c, prepare bulky non-woven fabric, and spray polymer water-absorbing resin material on the upper surface of the bulky non-woven fabric; d , compound the lower surface of the bulky non-woven fabric on the upper surface of the product of step b; e, cut the product of step d to form a roll material with a smaller width; f, combine the product of step d Transport in a continuous manner; g, prepare the bottom non-woven fabric, and then compound it with the upper surface of the bulky non-woven fabric; The woven bonded area is folded downwards and inwards so that it adheres to both lateral sides of the lower surface of the nonwoven.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a preparation method of an improved composite core. Background technique [0002] Absorbent cores are widely used in nursing absorbent articles. The traditional absorbent core is made of non-woven fabric coated with wood pulp or fluff pulp to form a block structure. In order to further increase the absorption performance of the core, polymer water-absorbing resin materials are usually mixed in wood pulp or fluff pulp. The resulting absorbent core not only tends to lump and break during use, but also has a thick structure, which reduces the comfort of the user. [0003] In order to solve the problem of lumping, breakage and thickness of the absorbent core, the existing absorbent core is usually set up as a five-layer absorbent core and then laminated with a layer of non-woven fabric, refer to figure 1 Its structure is that the upper and lower surfaces of the middle no...
