Problems solved by technology

[0003] The anti-side leakage on both sides of the existing products is usually only a single-layer covering three-dimensional protective enclosure formed by a layer of water-repellent non-woven fabric and elastic parts. The height of this three-dimensional protective enclosure is relatively short, and the wearing posture changes extremely. Easy to cause side leakage on both sides
In addition, the water-repellent non-woven fabric and the elastic parts in the areas other than the three-dimensional enclosures on both sides are directly bonded to the leak-proof bottom layer through hot-melt adhesive, so a flat leak-proof enclosure is formed on both sides of the sanitary product. The body is bonded between the leak-proof bottom layer and the water-repellent non-woven fabrics on both sides, instead of completely covering the absorbent core and the leak-proof bottom layer. If the absorption and permeation speed of the non-toxic surface material are not good, the existing sanitary products are prone to side leakage on both sides of the liquid
[0004] On the other hand, the plane leak-proof enclosure area provided on the outside of the three-dimensional enclosure is in direct contact with the thighs of the human body. Since this design is not set according to the human body structure, it is easy to cause poor body feeling due to friction when wearing, which affects the quality of sanitary products. fit and comfort

Embodiment 1

[0037] Such as Figure 1 to Figure 3 Shown, the preparation method of the sanitary article that the present invention has three-dimensional leak-proof enclosure, comprises the following steps:

[0038] Step 1, the first cladding device 10 (see Figure 8 ) Bending down the two left and right guards 20 along the first covering position A to perform the first covering, so that the guards 20 are divided into the first covering section a1 and the first uncoating section a1 along the width direction. segment b1, and the width of the first covered segment a1 is smaller than the width of the first uncoated segment b1; the width of the first covered segment a1 can be properly adjusted according to the enclosure height of different products. The sum of the width of the first covered section a1 and the width of the first uncoated section b1 is the total width of the enclosure 20 .

[0039] Before the above-mentioned first coating device 10 performs the first coating, the first fixing g...

Embodiment 2

[0049] Such as Figure 4 to Figure 7 As shown, this embodiment is different from the above-mentioned embodiment 1. On the basis of the above-mentioned embodiment 1, a second coating process is added. The setting of the second coating process is to better form the inner double-layer edge protection twenty one. In this embodiment, the ends of the enclosure along the length direction are fixed to form two double-layer edge protections. In the middle section of the enclosure, due to the stretching effect of the inner enclosure elastic member 50, a ratio of implementation will be formed. In Example 1, the height is higher and the inner double-layer edge protection is better, so the three-dimensional leak-proof effect of Implementation 2 is obviously better than that of Example 1; and in Example 1, the end of the enclosure arranged along the length direction Only one double layer is formed (ie the inner double edge), but in the middle section of the enclosure, an inner double edge ...

Abstract

The invention discloses a manufacturing method of a sanitary product with a three-dimensional leak-proof enclosure, S1: a first coating device bends two left and right enclosures downward along the first coating position A to perform the first coating; S2 : Lay the absorbent main body on the first uncoated section b1 of the enclosure; S3: The third coating device bends the first uncoated section b1 upward along the third coating position C to perform the third clad. The three-dimensional leak-proof enclosure manufactured by the manufacturing method comprises an inner double-layer edge protection, an outer double-layer edge protection and a bending part. A sanitary product with a three-dimensional leak-proof guard, comprising the guard, the guard is arranged on the left and right sides of the absorbent main body in the sanitary product, and the absorbent main body includes leak-proof guards arranged sequentially from bottom to top. A backsheet, an absorbent core, and a liquid-permeable topsheet. Compared with the prior art, the invention has the advantages of good leakage prevention effect, comfortable wearing and the like.

Description

technical field [0001] The invention belongs to the technical field of hygienic products manufacturing, in particular to the fields of sanitary napkins, paper diapers, pull-up pants, sanitary pants and the like, and in particular to a sanitary product with a three-dimensional leak-proof enclosure and a manufacturing method thereof. Background technique [0002] In disposable hygiene products, three-dimensional protection has become an indispensable part of the product. The three-dimensional enclosure is the leak-proof structure on both sides. It is generally made of water-repellent non-woven fabric, elastic parts, and hot-melt adhesive applied to the elastic parts. Due to the shrinkage of the elastic parts themselves, the water-repellent non-woven fabric is in the same The formed folds form a three-dimensional leak-proof enclosure on both sides along the length of the product, effectively preventing side leakage of liquid. [0003] The anti-side leakage on both sides of the...
