Double-diversion composite core

Abstract

The invention discloses a double-diversion composite core. The core comprises a water resisting layer and an outer cladding layer. Two sides of the water resisting layer are symmetrically fixed with awater absorbing layer. The water absorbing layer comprises an inner cladding layer, water absorbing particles and bulk cotton. The inner cladding layer is of a boss-like structure, the bulk cotton isfixed in the middle of the inner cladding layer, and the water absorbing particles are filled inside the inner cladding layer. One side of the inner cladding layer away from the water resisting layeris fixed with a diversion layer, and one side of the diversion layer away from the inner cladding layer is fixed with a surface layer. The outer cladding layer wraps the outsides of the water resisting layer, the water absorbing layer, the diversion layer and the surface layer. An opening is formed in the top of the outer cladding layer. A nylon hook belt is fixed on the inner side of the top ofthe outer cladding layer. By means of conversion of the position of two surface layers, the composite core can be used twice, so that waste of a package material is reduced. In addition, the fluid canbe absorbed in a concentration mode, and the usage rate of a water absorbing material and the water absorption capability of a composite core material are improved.

Description

technical field [0001] The invention relates to the technical field of composite core materials, in particular to a double-guiding composite core body. Background technique [0002] Absorbent core is the most important component of disposable absorbent products. The performance of disposable absorbent products is mainly determined by absorbent core, such as water absorption, retention, diffusibility, etc. [0003] Composite absorbent core materials are often used as materials for making diapers. Most of the composite absorbent core materials in the prior art have only one diversion surface, so that the diaper products can only be used once, which will cause serious damage to the packaging materials of the diaper products. A lot of waste, and the water-absorbing layer of the existing composite core material is evenly arranged, and the body fluid cannot be concentratedly absorbed according to the baby's body parts, which reduces the water-absorbing performance of the composite...

[0003] Composite absorbent core materials are often used as materials for making diapers. Most of the composite absorbent core materials in the prior art have only one diversion surface, so that the diaper products can only be used once, which will cause serious damage to the packaging materials of the diaper products. A lot of waste, and the water-absorbing layer of the existing composite core material is evenly arranged, and the body fluid cannot be concentratedly absorbed according to the baby's body parts, which reduces the water-absorbing performance of the composite core material and causes some water-absorbing materials to not be fully used.
