Problems solved by technology

[0015] In the prior art, although the wood pulp and the polymer water-absorbing resin are used to cooperate with each other, the wood pulp used is used after the wood pulp is crushed. Fine particles, although it can improve the water absorption performance of baby diapers in the prior art, but because the baby is hyperactive, the integrity of wood pulp and polymer water-absorbent resin is poor, resulting in the phenomenon of lumping of the water-absorbent core layer is difficult to achieve ideal As a result, the air permeability of baby diapers in the prior art is poor, and it is easy to cause red spots on the baby's buttocks.

Embodiment 1

[0063] Embodiment 1: a kind of dry and comfortable, breathable paper diapers, such as figure 1 and figure 2 As shown, it includes a diaper body, a three-dimensional enclosure structure 2 arranged on the diaper body, an elastic structure 3 arranged on the diaper body and the three-dimensional enclosure structure 2; the diaper body includes a composite core layer 11 and a composite core layer 11 External cladding structure. Wherein, the composite core layer 11 includes a core inner layer 111 and a core wrapping non-woven fabric 112 wrapped outside the core inner layer 111 .

[0064] The core inner layer 111 includes a core upper layer breathable cloth 1111, a middle layer fluffy fiber mesh 1112, a core lower layer breathable cloth 1113, between the upper layer non-woven fabric and the middle layer fluffy fiber mesh 1112, the middle layer fluffy fiber mesh 1112 and the core lower layer breathable cloth 1113 An acrylic type superabsorbent resin layer is arranged between them. ...

Embodiment 2

[0075] Embodiment 2: A dry and breathable paper diaper, the difference from Embodiment 1 is that in step 1, the pretreatment of ES fibers: the concentration is 5% sericin aqueous solution is sprayed on the long-fiber ES fibers, Dry at 30°C in a sterile environment, and then cut the ES fibers into short fibers with a length of 50-80 mm, wherein the ratio of sericin aqueous solution to long-fiber ES fibers is 1:2. Then the long fibers are cut into short fibers, and the middle fluffy fiber web 1112 with a thickness of 0.1 mm is prepared by hot air method.

Embodiment 3

[0076] Example 3: A dry and breathable paper diaper, the difference from Example 1 is that in step 1, during the pretreatment of ES fibers, the concentration of sericin aqueous solution is 6%, and the drying temperature is 33°C. And the ratio by weight of the sericin aqueous solution to the long-fiber ES fiber is 1:3. The thickness of the middle fluffy web 1112 is 0.2 mm.

Abstract

The invention discloses a dry and breathable diaper and its production process. The diaper comprises a diaper body, a composite core layer and a cladding structure coated on the outside of the composite core layer; The outer core of the inner layer is wrapped with non-woven fabric; the inner layer of the core includes the upper core air-permeable cloth, the middle fluffy fiber net, the lower core air-permeable cloth, between the upper non-woven fabric and the middle fluffy fiber net, the middle fluffy fiber net and the There is a layer of water-absorbing particles between the breathable cloth on the lower layer of the core; the covering structure includes the upper layer of non-woven fabric, the lower layer of non-woven fabric, the breathable waterproof membrane and the bottom layer of non-woven fabric, and the lower layer of non-woven fabric is bonded to the composite core layer. Then, the lower non-woven fabric is bonded to the breathable waterproof membrane, and the breathable waterproof membrane is bonded to the bottom non-woven fabric. The paper diaper has the advantages of good water absorption effect, dryness and breathability, and is not easy to cause the baby to have red buttocks.

Description

technical field [0001] The invention relates to the technical field of paper diapers, more specifically, it relates to a dry and breathable paper diaper and a production process thereof. Background technique [0002] Diapers and pull-up pants are very important for babies of different ages, because they have a certain water absorption effect and are disposable, so they are deeply loved by parents with babies. [0003] The design principles of diapers and pull-up pants are similar, and they all use polymer water-absorbent resin as the main component. At present, some traditional diapers and pull-up pants are combined with wood pulp to form a water-absorbent core together with polymer water-absorbent resin. The polymer water-absorbent resin in the water-absorbent core is a highly water-absorbent carrier for storing water, which can absorb 150 times its own weight of water. It has many advantages such as non-toxic, harmless, no peculiar smell, no mosquitoes, and no pollution. ...
