Embodiment Construction

[0040] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0041] refer to Figure 1 to Figure 9 , the present embodiment provides a method for preparing a composite core, including a main body 1 and production equipment for manufacturing the main body 1, the main body 1 includes an upper layer absorbent core 11, a middle layer absorbent core 12 and a lower layer absorbent core 13 stacked in sequence, the upper layer The width of the absorbent core 11 is the same as that of the middle absorbent core 12, the width of the lower absorbent core 13 is greater than the width of the upper absorbent core 11 by 1 cm to 3 cm, and the thickness of both sides of the lower absorbent core 13 is smaller than that of the middle part. 13, both sides are folded upwards and pressed on the top surface of the upper absorbent core 11 to form a groove 10 along the length direction. The upper absorbent core 11 is provided with thr...

Abstract

The invention relates to a preparation method of a composite core. The composite core comprises a body and production equipment for producing the body, wherein the body comprises an upper layer absorption core, a middle layer absorption core and a lower layer absorption core which are stacked in sequence; the upper layer absorption core is provided with at least one first flow guide groove in thelength direction; and at least one second flow guide groove in the width direction is formed in the middle layer absorption core. The invention relates to the field of disposable hygienic products. Through the arrangement of a three-layer composite structure, the first flow guide groove and the second flow guide groove, liquid can be guided in all directions of the body, all parts of the body canfully absorb the liquid, meanwhile, a large amount of the liquid is prevented from being concentrated in the middle of the core, the flow guide and absorption capacity of the body is enhanced, and thetechnical problems that the absorption cores are poor in flow guide effect, low in absorption speed and poor in absorption effect, and the flow guide grooves are difficult to form in the absorption cores are solved.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a preparation method of a composite core. Background technique [0002] When the existing disposable sanitary products are used, when the liquid enters the disposable sanitary product, the liquid is concentrated in the middle of the absorbent core, and then diffuses to the surroundings, and the absorbent core absorbs the liquid. Launders are usually arranged along the length direction, and the inside of the absorbent core is densely arranged polymer materials. If a large amount of liquid enters the absorbent core at the same time, due to the limited absorption speed of the absorbent core, the liquid is usually concentrated in the middle of the absorbent core and often absorbs The middle part of the core is saturated very quickly. Usually, the liquid diffuses to the surrounding after the absorption of the central absorbent core is saturated. The liquid diffuses slowly i...
