[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 sheared, it must Cutting according to a circle or an ellipse results in a high proportion of waste after cutting, especially at the edge of a strip-shaped substrate. After cutting according to a circle, the waste formed by the part between adjacent circles on the edge ,area

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] like 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

A production process for a breast pad and a breast pad. A water absorbing layer comprises a plurality of single water absorbing bodies (3) arranged in a plurality of vertically spaced columns. The single water absorbing bodies (3) in the same column are vertically symmetrically distributed. The single water absorbing bodies (3) in the adjacent columns arranged oppositely of the circular arc parts (3-1) are staggered. The single water absorbing bodies (3) in the adjacent columns arranged oppositely of the radial line parts (3-2) are arranged in a spaced manner and in a transversely symmetrical manner. The radial line parts (3-2) of the single water absorbing bodies (3) at two side edges of the water absorbing layer in the length extending direction are distributed toward the outer side. A water guiding layer above each single water absorbing body (3) is paved. Along the periphery of each single water absorbing body (3), the waterproof layers and the water guiding layers are welded by ultrasonic or connected by melting to obtain an integrated belt shaped base material (4). The belt shaped base material (4) is folded along the central lines of clearances of adjacent columns arranged oppositely of the radial line parts (3-2) and each pair of breast pad half bodies (2) are vertically symmetrically folded, the side edges of the radial line parts (3-2) of each pair of folded breast pad half bodies (2) are welded by ultrasonic or connected by melting, shearing or integrally blanking according to the preset size of the periphery of each single water absorbing body (3) is conducted, thereby obtaining 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] like 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 shear...
