Abstract

The invention belongs to the field of mechanical manufacturing, and relates to composite nonwoven fabric.The composite nonwoven fabric comprises first fabric and second fabric, multiple first protrusions are arranged on the first fabric, multiple second protrusions are arranged on the second fabric, the first fabric is compounded to the second fabric, the second protrusions are located in cavities of the first protrusions to form fiber bags, rough selvedge fibers on the opposite faces of the first protrusions and the second protrusions make contact in a staggered mode, and protrusive patterns are arranged in gaps between the fiber bags.The composite nonwoven fabric has the advantages that the manufactured elastic fabric has clear texture, the protrusions are stereoscopic and full, the appearance effect is remarkably promoted, and as double layers of coincident protrusions are arranged, the composite nonwoven fabric has pliable and tough touch sense and can resist deformation such as toppling, depression and flattening.Due to the full and stable protrusions, the composite nonwoven fabric has good ventilating, dry and comfortable performance; by means of the fiber bags formed by the double layers of the coincident protrusions, the absorbing and drainage effects and absorption performance are promoted remarkably in comparison with common fabric with protrusions.

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...
