Method for producing breast pads and breast pads obtained therefrom

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...

[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
