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] like 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 glue...

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 method for manufacturing a sanitary towel with three-dimensional leakproof enclosures. The method comprises the steps that S1: a first covering device bends the left enclosure and the right enclosure downwards along a first covering position A for primary covering; S2: an absorbent body is laid on a first uncovered section b1 of each enclosure; and S3: a third covering device bends the first uncovered sections b1 upwards along a third covering position C for ternary covering. Each three-dimensional leakproof enclosure manufactured with the method comprises an inner double-layer protection edge, an outer double-layer protection edge and a bent portion. The sanitary towel comprises the enclosures, the enclosures are arranged on the left side and the right side of the absorbed body of the sanitary towel, and the absorbent body comprises a leakproof bottom layer, an absorbent core and a liquid-pervious surface layer which are arranged from bottom to top in sequence. Compared with the prior art, the sanitary towel has the advantages of being good in leakproof effect, comfortable in use 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...
