The gas permeability and absorbability of cotton core are the main functional characteristics of paper diaper and sanitary napkin.If paper diaper, sanitary napkin The cotton core absorbent properties of equal amenities are bad, and greatly puzzlement and inconvenience will be brought by excreta leakage occur.And Poor air permeability then can bring feeling of oppression and heat to people, and greatly uncomfortable, especially period of the opposite warm of temperature is brought when wearing.It produces The characteristics such as the comfort property of product and major function are that the focus to stand in the breach once these performances are poor then will lead to people couple Product and product producer are lost the confidence, and distrust are generated, to influence the selling bank of corporate image and related industry Feelings.

A common sanitary absorbent article core has traditional core and compound core body on the market.Traditional core is more Two kinds of common forms are: the form of wood pulp+SAP mixing core and wood pulp+SAP layer distributed.Traditional core flexibility it is good with It is flow conductivity strong, but it is more thick and heavy, and gas permeability is poor, and core is easy to be hardened after extruding, destroys the flexibility of itself, not to people Comfortable sense of touch.

Utility model content

Therefore, for above-mentioned problem, the utility model proposes it is a kind of it is simple and reasonable, use comfortable ventilating, absorb The superior novel core of performance.

To solve this technical problem, the utility model takes following scheme: a kind of novel core, including internal layer and complete packet The non-woven fabrics outer layer of internal layer is covered, the internal layer is by non-woven fabrics upper layer, wood pulp and SAP mixed layer, fibrous layer, SAP layers and non-woven fabrics Lower layer stacks gradually compound composition, and the internal layer is laid with plural number between non-woven fabrics upper layer and wood pulp and SAP mixed layer A through-hole and the plurality of through holes constitute multiple rows of horizontal and vertical mutually spaced array, are equipped in the fibrous layer vertical To spaced a plurality of strip SAP layers, plurality of through holes composition is respectively arranged on for each strip SAP layers in the fibrous layer Below the through-hole of the longitudinal arrangement of array.

Further to improve, the through-hole diameter being arranged on the internal layer is 3mm-5mm.

It is further to improve, multiple heat seal points are also laid on the internal layer and the heat seal point is mutually staggered with through-hole.

Further to improve, the heat-sealing spot diameter on the internal layer is 1.2mm-1.8mm.

By using preceding solution, the beneficial effects of the utility model are: by wood pulp and SAP mixed layer and Fibrous layer is equipped between SAP layers, due to fibrous layer have absorbent properties but not the SuperPro of SAP it is aqueous can, enable fibrous layer Water conservancy diversion and ventilative effect are enough played, wood pulp and SAP mixed layer can be effectively prevent and SAP layers of layer is blocked up leads to gas permeability Difference, by the plural number that horizontal and vertical array arrangement is arranged between the non-woven fabrics upper layer of internal layer and wood pulp and SAP mixed layer A through-hole is greatly improved the penetrating power of core, absorbability and permeability, and a plurality of length is arranged in interval in fibrous layer SAP layers of bar shaped, its water conservancy diversion and adsorption capacity can be further enhanced, core, which is equipped with multiple heat seal points, can effectively consolidate internal layer knot Structure will not guarantee the permeability and gas permeability of intermediate three-dimensional fibrous layer because of extrusion deformation, and outermost layer is equipped with full cladding nonwoven Core is entirely wrapped, reinforces the fixation of core by cloth, prevents core from using comfortable ventilating, absorbing because loose caused by external force Performance is more excellent, simple and reasonable, can wide popularization and application.

Detailed description of the invention

Fig. 1 is the transversal cross-section structural schematic diagram of the utility model embodiment.

Specific embodiment

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

With reference to Fig. 1, the novel core of preferred the utility model, the non-woven fabrics outer layer including internal layer and cladding internal layer completely 1, the internal layer is stacked gradually by non-woven fabrics upper layer 2, wood pulp and SAP mixed layer 3, fibrous layer 4, SAP layer 5 and non-woven fabrics lower layer 6 Compound composition, the internal layer are laid with plurality of through holes 7 between non-woven fabrics upper layer 2 and wood pulp and SAP mixed layer 3 and should Plurality of through holes 7 constitutes multiple rows of horizontal and vertical mutually spaced array, sets in the fibrous layer 4 equipped with longitudinal gap The a plurality of strip SAP layer 41 set, each strip SAP layer 41 is respectively arranged on the battle array of the composition of plurality of through holes 7 in the fibrous layer 4 Below the through-hole 7 of the longitudinal arrangement of column, the through-hole diameter being arranged on the internal layer is 4mm, is also laid on the internal layer more A heat seal point and heat seal point is mutually staggered with through-hole 7, the heat-sealing spot diameter on the internal layer are 1.4mm.

The through-hole diameter being arranged on internal layer described in the utility model is preferred with 3mm-5mm, the heat seal point on the internal layer Diameter is preferred with 1.2mm-1.8mm.
