The present invention relates to a kind of absorbent material, relate in particular to a kind of suction core body for hygienic article.
Technical background
The suction core body is one of main material of making by the hygienic article such as sanitary towel, diaper, diaper, protective pad; the suction core body of prior art often adopts three-decker; the up and down is two-layer is protective layer; the centre is the water-absorption particle carrier; and hydroscopic high-molecular resin granule (SAP) sprays on the water-absorption particle carrier uniformly; hydroscopic high-molecular resin has good water absorption and lock aqueous as topmost absorbent material in the suction carrier.
The publication number of applying for before the applicant is that the patent of invention of CN102700179A discloses a kind of suction core body for hygienic article, described suction core body comprises the first dustless ply of paper that is positioned at the upper strata, the second dustless ply of paper that is positioned at the nonwoven layer in intermediate layer and is positioned at lower floor, it is characterized in that: described dust-free paper is after ES fiber mixing with the wood pulp cellulose of weight content 60～80% and weight content 20～40%, adopts dry method of paper-making technique to make; The described first dustless ply of paper and the second dustless ply of paper form bound edge along nonwoven layer both sides hot melt adhesive.Its weak point is: the hydroscopic high-molecular resin on non-woven fabrics is evenly distributed on non-woven fabrics, and sanitary towel, disposable urine trousers, pad for incontinence etc., water absorbing properties to suction core body middle part is had relatively high expectations, the water absorbing properties at two ends requires low, the hydroscopic high-molecular resin granule at suction core body two ends is difficult to play a role, caused the waste of hydroscopic high-molecular resin, cost is higher.
Summary of the invention
In order to overcome the defective of prior art, the invention provides a kind of suction core body for hygienic article, by adjusting the distribution of hydroscopic high-molecular resin granule on its carrier, hydroscopic high-molecular resin is fully used, effectively save cost.
In order to realize the foregoing invention purpose; technical scheme of the present invention is: a kind of suction core body for hygienic article; comprise more than one water-absorbing core body unit; described water-absorbing core body unit comprises the water-absorption particle carrier; both sides, water-absorption particle carrier up and down are provided with protective layer; be distributed with the hydroscopic high-molecular resin granule on described water-absorption particle carrier, described hydroscopic high-molecular resin granule being distributed as on the water-absorption particle carrier: interlude is intensive, is reduced gradually to two ends by the centre.
Preferably, the hydroscopic high-molecular resin granule is normal distribution on the water-absorption particle carrier.
Preferably, described water-absorption particle carrier comprises one or more layers bonding non-woven fabrics mutually.
Preferably, described protective layer is dust-free paper.
Preferably, described water-absorption particle carrier is pulp layer.
Preferably, described protective layer is non-woven fabrics.
Preferably, described hydroscopic high-molecular resin granule adopts following equipment to spray: a kind of water absorbing polymer particle flusher, comprise material storing box and spill material roller, the described material roller that spills is positioned at bottom material storing box, spill material roller and material storing box is tightly connected, spill material roller and be provided with some pits, described pit axially is evenly distributed along spilling material roller, is normal distribution along circumference.
Preferably, described material storing box bottom is provided with two baffle plates with spilling the material roller junction, is positioned at the horizontal baffle on right side, material storing box bottom and the slanting baffle in left side.
Preferably, the described material roller that spills is connected with motor by power transmission shaft.
Hydroscopic high-molecular resin granule of the present invention is normal distribution on the water-absorption particle carrier, namely the intermediate distribution amount is maximum, evenly reduces to two ends, and in using with reality, the suction situation of each several part is consistent, and has avoided the waste of hydroscopic high-molecular resin granule.The hydroscopic high-molecular resin granule is as the present best absorbent material of effect, and its price accounts for suction core body cost of material proportion larger greatly about 20000-25000 yuan/ton, therefore, adopts the water-absorbing core body of the technical program effectively to save cost, increases the benefit.

The specific embodiment
The present invention will be further described below in conjunction with concrete the drawings and specific embodiments:
As shown in Figure 1: a kind of suction core body for hygienic article, comprise more than one water-absorbing core body unit, each water-absorbing core body unit comprises upper and lower two-layer dust-free paper 1 and is positioned at the middle non-woven fabrics 2 of two-layer dust-free paper 1, be distributed with the hydroscopic high-molecular resin granule on described non-woven fabrics 2, described hydroscopic high-molecular resin granule being distributed as on the non-woven fabrics 2 of each water-absorbing core body unit: interlude is intensive, by the normal distribution of centre even minimizing to two ends.
By changing the distribution of hydroscopic high-molecular resin granule on non-woven fabrics 2, can effectively save cost, increase the benefit.The suction core body that adopts traditional distribution mode to make approximately half ton of hydroscopic high-molecular resin granule of consumption that need per ton, and per ton of the composite absorbent paper after changing needs to consume the hydroscopic high-molecular resin granule of 0.3～0.4 ton, according to 20000～25000 yuan/tons of the prices of the hydroscopic high-molecular resin granule of existing market, cost-saved 6000～9000 yuan of one ton of composite absorbent paper of every production.
Fig. 2 is the distribution curve of water-absorbing core body unit hydroscopic high-molecular resin granule from left to right, the total length of setting the water-absorbing core body unit is 1, the hydroscopic high-molecular resin granule content at place, water-absorbing core body unit middle is 1, the content at two ends, left and right is 0, and evenly reduces to two ends from the middle.
