Breast pad and production method thereof

Abstract

The invention relates to a breast pad and a production method thereof, which comprises: a water-conducting layer, a water-absorbing layer and a waterproof layer stacked in sequence, and elastically shrinkable rubber bands symmetrically arranged on both sides of the breast pad, and the four sides of the breast pad are respectively There is a heat-synthesized crimping line; the adjacent ends of the two crimping lines adjacent to each end are distributed alternately, and aligned up and down, or the adjacent ends of the two crimping lines can be projected on each other's crimping lines . When the breast pad of the present invention is in use, if the water-absorbing layer is saturated, the upper and lower sides of the two adjacent ends of the two adjacent pressure lines are alternately aligned due to the heat-synthesized sections around the breast pad. , or the adjacent ends of the two pressure lines can be projected on each other’s pressure lines. Compared with the prior art, this application changes the straight channel into a curved channel, so that the liquid and the polymer water-absorbing powder in the water-absorbing layer cannot be directly Leaking outward, and due to the surface tension of the liquid itself, the liquid cannot smoothly pass through the curved channel with a small diameter, thus preventing the liquid from leaking outward.

Description

technical field [0001] The invention relates to the technical field of breast pads, in particular to a breast pad and a production method thereof. Background technique [0002] Chinese patent document announcement number CN202999323U discloses a kind of anti-galactorrhea pad, comprises hydrophilic non-woven fabric (i.e. water-conducting layer), waterproof base film (i.e. waterproof layer) and absorber (i.e. water-absorbing layer) composition, such as figure 1 , the two ends of the gap formed by folding in half are fixed by embossing heat sealing, and the middle parts of the semicircles formed after folding in half are each provided with elastic bands 4, and the elastic bands 4 are fixed by rubber segments, so that the breast pads form a three-dimensional shape that is easier to fit. There are fixed diversion embossings 5 ​​around the center of the breast pad. [0003] On the production line for producing the above-mentioned breast pads, the elastic band is continuous and in...

Problems solved by technology

[0005] In actual production, if the entire section of elastic is fixed in the breast pad with rubber segments, or the two ends of the elastic are fixed between the hydrophilic non-woven fabric and the waterproof bottom film by thermosynthesis, such as image 3 , then, on the one hand, most of the contraction force of the elastic band will be offset by the tension of the water non-woven fabric and the waterproof bottom film in the breast pad, so that the edge of the breast pad will basically not shrink, and the ideal three-dimensional shape will not be ready-made; on the other hand , even if elastic with strong shrinkage force is used, after the overall elastic shrinks, the fit of the edge of the breast pad is poor, and the shape of the breast pad obtained cannot meet the requirements of design and use

[0006] In addition, if a waterproof membrane is used to partially wrap the absorbent body near the elastic band of the absorbent body, the corresponding production steps and production equipment will be adjusted accordingly, and the production efficiency will be greatly reduced; and the addition of a waterproof membrane , will increase the cost and will cause the product to lose competitiveness
