Abstract

The invention relates to the field of disposable sanitary products, in particular to a preparation method for an improved composite core. The problems of a complicated processing technology and high processing cost of a composite core in the prior art are mainly solved through the preparation method. The preparation method includes the following steps: (1) preparing non-woven fabric; (2) adding apolymer water-absorbing resin material to the non-woven fabric obtained in the step (1); (3) preparing bulk non-woven fabric, and spraying the polymer water-absorbing resin material to the top surfaceof the bulk non-woven fabric; (4) compounding the lower surface of the bulk non-woven fabric on the upper surface of the product obtained in the step (2); (5) cutting the product obtained in the step(4) so as to form a single rolled material with a small width; (6) conveying the product obtained in the step (4) in a continuous mode; (7) preparing underlayer non-woven fabric, and then compoundingthe underlayer non-woven fabric with the top surface of the bulk non-woven fabric; and (8) bending the areas, which are not adhered to the bulk nonwoven fabric, at two transverse sides of the underlayer non-woven fabric obtained in the step (7) downward and inward for coating so as to adhere the areas to the two transverse sides of the lower surface of the non-woven fabric.

Description

Technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a method for preparing 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 covered with wood pulp or fluff pulp to form a block structure. In order to further increase the absorption performance of the core, the wood pulp or fluff pulp is usually mixed with polymer water-absorbing resin materials, but this The resulting absorbent core is not only prone to lumps and breaks during use, but the structure of the absorbent core is often very thick, which will reduce the comfort of the user. [0003] In order to solve the problems of lumpiness, breakage and thickness of the absorbent core, the existing absorbent core is usually arranged in a five-layer structure and then laminated with a layer of non-woven fabric. figure 1 , Its structure is that the uppe...
