Problems solved by technology

However, the composite absorbent core with glue added is not environmentally friendly, and it will make it difficult for the liquid to be absorbed to pass through, thereby hindering the absorption of the liquid by the composite absorbent core, resulting in poor absorption effect; and the composite absorbent core formed by hot pressing The core body extrudes and deforms the fluffy air-through non-woven fabric, which makes the originally soft and fluffy composite absorbent core thinner and harder, thus seriously affecting its absorption effect

Embodiment 1

[0024] like figure 1 As shown, the fiber assembly is provided with two layers, and the two-layer fiber assembly is a fiber cotton net layer 2, and a layer of polymer superabsorbent resin 3 is provided, and this layer of polymer superabsorbent resin 3 is located on the two layers of fiber cotton net Between layers 2. Wherein, two-layer fiber cotton web layer 2 all is to utilize as the fiber cotton net that clearing machine goes out to make, and the square meter quality of described fiber cotton web layer 2 is 10 to 100 grams / square meter, is preferably 20 to 100 grams per square meter. 80 grams per square meter, and the fiber cotton net layer 2 can be made of the same core or eccentric core-sheath composite fiber whose core is made of polypropylene or polyester and the sheath is made of polyethylene, and the core is preferably made of polyester. The sheath and core are made of co-core core-sheath composite fibers made of polyethylene, and the thickness of the core-sheath compo...

Embodiment 2

[0026] like figure 2 As shown, the fiber assembly is provided with two layers, wherein one layer of the two-layer fiber assembly is a non-woven fabric layer 1, and the other layer is a fiber cotton layer 2, and the fiber cotton layer 2 is made of two layers of fiber Cotton webs are compositely formed by hot air bonding, and a layer of polymer superabsorbent resin 3 is provided, and the layer of polymer superabsorbent resin 3 is located between the non-woven fabric layer 1 and the fiber cotton web layer 2 . Among them, the non-woven fabric layer 1 is made by such as hot air method, hot pressing method (hot roller method), air-laid method, spinning melt spraying method, etc., and the fiber cotton webs that have been sorted out by a sorting machine are preferably used. The hot air at about 150°C is blown by the hot air method, so that the fibers are melted and bonded to form a non-woven fabric layer, and the non-woven fabric layer is a hot air-laid non-woven fabric layer. And t...

Embodiment 3

[0028] like image 3As shown, the fiber assembly is provided with three layers, the top layer and bottom layer of the three-layer fiber assembly are non-woven fabric layer 1, the middle layer is fiber cotton layer 2, and the fiber cotton layer 2 is made of two layers of fiber Cotton webs are compositely formed by hot air bonding, and a layer of polymer superabsorbent resin 3 is provided, and the polymer superabsorbent resin 3 is located between the top non-woven fabric layer 1 and the fiber cotton net layer 2 or the bottom non-woven fabric layer 1 and fiber cotton net layer 2. Among them, the non-woven fabric layer 1 is made by such as hot air method, hot pressing method (hot roller method), air-laid method, spinning melt spraying method, etc., and the fiber cotton webs that have been sorted out by a sorting machine are preferably used. The hot air at about 150°C is blown by the hot air method, so that the fibers are melted and bonded to form a non-woven fabric layer, and the...

Abstract

The invention relates to a composite absorbing core body, which comprises at least two layers of fiber assemblies and at least one layer of super-absorbing polymer resin, wherein each layer of fiber assembly and each layer of super-absorbing polymer resin are directly composited in one in a hot-air gluing mode on a hot-air gluing machine. As the hot-air gluing mode is adopted to make the at least two layers of fiber assemblies and the at least one layer of super-absorbing polymer resin into the composite absorbing core body structure, the soft fluffy properties of the composite absorbing core body are kept, the absorption capability of the composite absorbing core body is good, and the composite absorbing core body can absorb liquid more freely. Moreover, gluing on independent composite absorbing core body equipment is not needed after the fiber assemblies are made, and the hot-air gluing machine is used for direct gluing and sizing on hot-air non-woven fabric equipment through hot air, therefore, a production process of glue or heat-press gluing is removed. The environment is protected, and the production efficiency is effectively increased.

Description

technical field [0001] The invention relates to the field of hygienic products, in particular to a composite absorbent core which can be used in various disposable hygienic products such as mattresses, paper diapers, sanitary napkins, panty liners and panty liners. Background technique [0002] At present, disposable hygiene products using composite absorbent core materials, the composite absorbent core is made by purchasing non-woven fabrics or paper, and then using glue bonding or hot pressing on an independent composite core device to composite polymer superabsorbent resin. shaped. However, the composite absorbent core with glue added is not environmentally friendly, and it will make it difficult for the liquid to be absorbed to pass through, thereby hindering the absorption of the liquid by the composite absorbent core, resulting in poor absorption effect; and the composite absorbent core formed by hot pressing The core will extrude the fluffy air-through non-woven fabr...
