AI Technical Summary
The stretching range of existing elastic non-woven fabrics is limited by the elasticity of the elastic film, which is poor in elasticity and is difficult to meet the needs of diaper waist patches.
The top layer and bottom layer non-woven fabric are connected by a glue layer, and multiple parallel arranged 40D-85D elastic spandex filaments are arranged to form an elastic zone. The elastic zone is irregularly wrinkled in the stretched state, and the two sides are connected by a glue layer to form an elastic zone. In the elastic zone, the spacing between elastic spandex wires is 0.6-1.4mm, and the outer edges are straight, wavy or winding lines.
A greater elastic range and better tensile properties are achieved, allowing elastic non-woven fabrics to be more stablely connected to the diaper waist patch, suitable for diaper applications.

[0009] The utility model also provides a diaper waist patch, comprising a waist patch body, wherein the waist patch body is cut from the elastic non-woven fabric mentioned above.
[0010] Furthermore, one end of the waist patch body is connected to one side of the rear end of the diaper body, and the other end of the waist patch body is provided with one of Velcro, snaps, and magnetic buckles.
[0011] Beneficial Effects
[0012] Compared with the prior art, the utility model has at least the following advantages: the utility model forms an elastic zone by connecting a plurality of elastic spandex threads arranged equidistantly between the top non-woven fabric and the bottom non-woven fabric, which has high elasticity and can be conveniently cut into the required width along the direction parallel to the elastic spandex threads to be made into diaper waist stickers for use in diapers.

[0017] In order to make the purpose, technical scheme and advantages of the utility model clearer, a detailed description is given below in conjunction with the accompanying drawings and specific implementation methods. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific implementation disclosed below.
[0018] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
