Abstract

The invention belongs to the field of mechanical manufacturing. A composite nonwoven fabric includes a first fabric and a second fabric. The first fabric is provided with a plurality of first protrusions, and the second fabric is provided with a plurality of second protrusions. , the first fabric is compounded on the second fabric, and the second protrusion is located in the cavity of the first protrusion to form a fiber capsule, and the opposite surface of the first protrusion and the second protrusion The burr fibers are in interlaced contact, and the gaps between the fiber capsules are provided with raised patterns. The beneficial effect of the present invention is that: the elastic fabric produced by the present invention has clear texture, three-dimensional and plump protrusions, significantly improved appearance, has double-layered overlapping protrusions, is flexible and elastic to the touch, and can resist deformation such as dumping, depression, and flattening . The full and stable protrusions bring good breathability and dryness. The fiber capsule formed by the double-layer overlapping protrusions has a better absorption and fluid drainage effect than ordinary raised fabrics, and the absorption performance is significantly improved.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a composite nonwoven fabric and a manufacturing device thereof. Background technique [0002] Disposable sanitary products such as sanitary napkins, diapers, mattresses and other products are made of a variety of sanitary substrates. Since such products are in direct contact with the user's skin, this type of product is of great importance for the selection of sanitary substrates. Strict requirements, that is, to consider its excellent absorption performance, but also to take into account its use comfort and aesthetics. The surface layer of sanitary products is in direct contact with users. The surface layer of commercially available hygienic products is mostly made of flat and soft hydrophilic non-woven materials, and the bottom of the material is combined with a flow-guiding material to meet the absorption and comfort requirements. requirements. However, th...
