[0019] The following will describe the implementation methods of the present invention in detail in conjunction with specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] Embodiment 1

[0021] refer to Figure 1 and Figure 2 A new type of waist circumference menstrual pants, which is mainly produced by introducing new materials to produce existing menstrual pants. This new material replaces the traditional elastic waist and traditional viscose materials. The menstrual pants as a whole include a layered liquid-permeable surface layer, an absorbent core layer and a liquid-impermeable bottom layer. The length direction of the menstrual pants is defined as the longitudinal direction, the width direction is the transverse direction, and the position of the menstrual pants when worn by the human body is divided into a front part a, a crotch part b and a back part c. A TPU mesh layer 1 for bonding and providing waist elasticity is provided between the liquid-permeable surface layer and the liquid-impermeable bottom layer at the waist of the front part a and the back part c; wherein the TPU mesh layer 1 is composed of polyurethane, has a white irregular mesh surface, is neutral and odorless, and has a melting range (DSC) of :98-118℃; TPU mesh layer 1 is a new material to replace the traditional elastic waist structure. It is a non-woven hot melt adhesive mesh product. It has no stickiness at room temperature and can save the backing paper of the traditional production line. It is soft and elastic under normal conditions. After reaching the melting temperature, it can achieve the bonding effect. Compared with traditional elastic non-woven fabrics, it has good air permeability and a lower gram weight, which can be as low as 15g / ㎡, which is beneficial to reduce the overall weight of the entire menstrual pants product. Compared with elastic parts such as rubber roots and spandex yarns, it can retain the advantages of traditional elastic non-woven fabrics, can be easily operated continuously or intermittently, is beneficial to production, and achieves a balance between air permeability, production efficiency and production cost.

[0022] Structurally, the entire TPU mesh layer 1 can achieve various forms of waist bonding structures by adjusting the hot pressing mold under the composite conditions, and can adjust the different outer surface structures of the waist according to the needs, which greatly enriches the product line and has a good use prospect. The TPU mesh layer 1 and the liquid-permeable surface layer and the liquid-impermeable bottom layer described in this embodiment are formed by hot pressing welding to form a plurality of connection points 11 arranged in a rectangular array. By covering the connection points 11 distributed in a lattice shape throughout the waist, the entire elastic waist located between the connection points 11 forms a plurality of unbonded shrinkage spaces 12, and the surface layer and bottom layer materials at the shrinkage space 12 are retracted, thereby providing a softness and comfort different from the traditional elastic waist while ensuring the elasticity at the waist.

[0023] Embodiment 2

[0024] refer to Figure 3 , Figure 4 In this embodiment, the TPU mesh layer 1 and the liquid-permeable surface layer and the liquid-impermeable bottom layer are welded by hot pressing to form a plurality of strip-shaped connecting lines 13 extending longitudinally and evenly distributed. The connecting lines 13 can be adjusted to different welding widths, densities and positions by adjusting the hot pressing mold, making the production of the product line more flexible;

[0025] The following structures are two specific examples, which are two applications with different orientations formed according to this structure:

[0026] ①, the connecting line 13 is divided into a waist end portion 131 close to the waist of the human body and a crotch end portion 132 close to the crotch portion b, and the layout density of the waist end portion 131 is less than that of the crotch end portion 132; under this structure, the waist end portion 131 and the crotch end portion 132 can form different softness and breathability structures, the layout density of the waist end portion 131 is small, so that the breathability of this position can be guaranteed, and the density of the crotch end portion 132 is large to ensure that the overall elasticity is sufficient to avoid being detached when worn;

[0027] ②. The connecting line 13 is divided into a waist end portion 131 close to the waist of the human body and a hip end portion 132 close to the crotch portion b. The arrangement density of the waist end portion 131 is greater than that of the hip end portion 132. Under this structure, the size of a single connecting line 13 at the waist end portion 131 is smaller than that of the hip end portion 132, which can form a dense and flexible feel at the waist end portion 131 to improve the comfort when in contact with human skin.

[0028] On this basis, similarly, the TPU mesh layer 1 and the liquid-permeable surface layer and the liquid-impermeable bottom layer are welded by hot pressing to form multiple strip-shaped connecting lines 13 evenly distributed in the transverse direction. This structure is different from traditional trouser-type sanitary products, and the flexible structure distribution formed is different, which is another product line.

[0029] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
