Problems solved by technology

[0002] The breast pads for breast-feeding women in the prior art include a hydrophilic layer, an absorbing layer and a water-repelling layer (also called a waterproof layer) from the inside to the outside; the absorbing layer mainly includes a polymer water-absorbing resin ( Abbreviated as SAP), its shortcoming is that the absorbent layer completely fills the space between the hydrophilic layer and the waterproof layer, and the absorbent layer swells due to water absorption during use, but at this time the gap between the hydrophilic layer and the waterproof layer The space between them is basically filled, and there is little room for expansion. However, it is necessary to provide enough expansion space for SAP to fully absorb water.
This results in the absorbent layer not being able to fully absorb water and the SAP not being saturated, which in turn makes the breast pads less absorbent

Embodiment 1

[0024] Such as Figure 1-2 As shown, the breast pad with better water absorption performance in this embodiment comprises a hydrophilic layer 1, an absorbent layer 2 and a waterproof layer 3 which are sequentially stacked. The hydrophilic layer 1 and the waterproof layer 3 are symmetrical up and down, and the surrounding edges are heated by heat The pressure rollers are fused or ultrasonically welded to form a welded ring 4; the absorbing layer 2 is bonded between the hydrophilic layer 1 and the waterproof layer 3; the area occupied by the absorbing layer 2 in the welded ring 4 is 85%, or 82%, or 80%, or 77% of the area of ​​the inner ring of the fusion ring 4.

[0025] The absorption layer 2 is located in the center of the fusion ring 4, and the absorption layer 2 is rectangular, oval or circular; the upper and lower sides of the absorption layer 2 are bonded with butterfly-shaped dust-free paper, and / or Toilet paper, and / or fluff pulp layer 2-1, to guide the water on the ou...

Embodiment 2

[0033] On the basis of Embodiment 1, the breast pad in this embodiment has the following modifications:

[0034] Such as image 3 The end of the hydrophilic layer 1 adjacent to the absorbent layer 2 is respectively provided with a water-retaining strip 5 perpendicular to the folded center line A-A, and the water-retaining strip 5 is folded and formed by the material of the absorbent layer 2. The two ends of the water bar 5 are welded or ultrasonically welded on the welding ring 4 by hot pressing rollers; when a pair of water retaining bars are used, they are arranged in parallel up and down to avoid overflow of milk.

[0035] The outer edge of the water-retaining strip 5 is pierced with elastic or elastic fiber 6 in a shrinking state, so that the product shrinks into an arc that fits the breast of a human body.

[0036] The elastic or elastic fiber 6 is bonded in the water retaining strip 5 .

Abstract

The invention relates to and provides a breast pad with better water absorption performance, which comprises a hydrophilic layer, an absorption layer and a waterproof layer which are laminated sequentially, wherein the hydrophilic layer and the waterproof layer are vertically symmetric, and the peripheral edges are connected by a hot pressing roller or ultrasonic welding to form a welding ring; the absorption layer is bonded between the hydrophilic layer and the waterproof layer; the occupied area of the absorption layer in the welding ring does not exceed 85 percent of the inner ring area ofthe welding ring to provide sufficient expansion space for an SAP in the absorption layer, so that the SAP can fully absorb water and finally reach a saturated state, and is no longer restricted by the expansion space to hinder water absorption. By testing, the water absorption capacity of the breast pad of the invention is improved by 10 percent compared with the prior art under the condition that the weight of the SAP used in the breast pad of the invention is 10 percent lighter than the prior art.

Description

technical field [0001] The invention relates to the technical field of breast pads for lactating women, in particular to a breast pad with better water absorption performance. Background technique [0002] The breast pads for breast-feeding women in the prior art include a hydrophilic layer, an absorbing layer and a water-repelling layer (also called a waterproof layer) from the inside to the outside; the absorbing layer mainly includes a polymer water-absorbing resin ( Abbreviated as SAP), its shortcoming is that the absorbent layer completely fills the space between the hydrophilic layer and the waterproof layer, and the absorbent layer swells due to water absorption during use, but at this time the gap between the hydrophilic layer and the waterproof layer The space between them is basically filled, and there is little room for expansion. However, it is necessary to provide enough expansion space for SAP to fully absorb water. This results in the absorbent layer not bein...
