Embodiment 1

[0032] See Figure 10-12 , the production method of the breast pad of the present embodiment comprises the steps:

[0033] A. Lay a water-absorbing layer on the waterproof layer or the water-conducting layer; wherein, the water-absorbing layer includes multiple vertical rows alternated along the length direction of the substrate 4 (the substrate 4 includes a waterproof layer and a water-conducting layer stacked up and down) parallel A plurality of semicircular or substantially semicircular water-absorbing units 3 are arranged; as shown in the figure, the water-absorbing unit 3 includes: an arc portion 3-1 and a radial portion 3-2. The water-absorbing units 3 in the same row are symmetrically distributed sequentially along the arrangement direction, the water-absorbing units 3 in the adjacent columns opposite to each other are arranged alternately, and the arcs of the water-absorbing units 3 in any row 3-1 can be projected on the arc portion 3-1 of the adjacent water-absorbing...

Embodiment 2

[0040] Such as Figure 5 The half-body 2 of the breast pad in the base material 4 adopts another distribution method. After each half-body 2 of the breast pad is cut off, a pair of half-body 2 of the breast pad is welded along the radial line to form a breast pad. Mat finished.

Embodiment 3

[0042] On the basis of above-mentioned embodiment 1, the difference of this embodiment is:

[0043] Stack the two base materials up and down, and the upper and lower adjacent pairs of breast pad halves formed after stacking are stacked symmetrically up and down, and then ultrasonically welded along the edges of the radial parts of each pair of superimposed breast pad halves or hot melt connection.

[0044] In this step, there is no need to turn over the base material, and only need to ensure that the material is set, and the step of ultrasonic welding or thermal fusion connection can be performed, which can further improve production efficiency.

Abstract

The invention relates to a production method of a breast pad and the breast pad. The production method is characterized in that a water absorbing layer comprises a plurality of single water absorbing bodies which are lengthways alternatively arranged into a plurality of rows. The production method comprises the following steps: vertically symmetrically distributing the single water absorbing bodies in the same row; arranging the single water absorbing bodies of which circular arc parts are oppositely arranged, in adjacent rows by a staggering manner; transversely, symmetrically and alternatively arranging the single water absorbing bodies of which radial line parts are oppositely arranged, in adjacent rows; distributing the radial line parts of the single water absorbing bodies at two side edges of the water absorbing layer in the length extending direction toward the outer side; paving a water guide layer above each single water absorbing body; connecting waterproof layers and the water guide layers by welding through ultraviolet or hot melting along the periphery of each single water absorbing body, so as to obtain an integrated belt shaped base material; folding the belt shaped base material along the central lines of clearances of adjacent rows in which the radial line parts are oppositely arranged; folding the belt-shaped base material; vertically symmetrically folding half bodies of each pair of breast pads; connecting along the side edges of the radial line parts of half bodies of each pair of folded breast pads by welding through ultraviolet or hot melting; shearing according to the preset size of the periphery of each single water absorbing body or integrally blanking to obtain a plurality of finished breast pad products.

Description

technical field [0001] The invention relates to the technical field of breast pads, in particular to a production method of breast pads and the obtained breast pads. Background technique [0002] Such as Figure 1-2 , the Chinese patent document CN202095548U discloses a disposable breast milk overflow pad (also known as a breast pad), including a body 5, the body 5 is circular, elliptical or regular polygonal, and a cutout 6 is formed through a mold along the center of the body. , and the incision is bonded to form a depression on one side of the main body 5 to form a three-dimensional 3D shape, which fits the chest more closely and is more comfortable to use. [0003] The deficiency of above-mentioned prior art is: as image 3 or 4, when the tape-shaped substrate 4 composed of multi-layer laminated materials (at least including the impermeable film layer (ie, waterproof layer), water-absorbing layer and non-woven moisture-permeable layer (ie, water-conducting layer)) is sh...
