CN2363685Y - Dry coated mesh layer having good permeability - Google Patents

Abstract

The utility model discloses a dry mesh surface having good permeability. The dry mesh surface is mainly characterized in that the shape of an orifice of each mesh opening of the mesh surface forms a quadrangle shape; the mesh surfaces arranged among the adjacent miniature mesh openings are provided with convex surfaces which are bulged towards the upper part of the mesh surface; a mesh surface around each convex surface is inclined downwards to form a flow slope which is connected with adjacently ambient orifices of a plurality of miniature mesh openings. The utility model is widely used for women hygiene supplies, baby urine trousers, medical mattresses, and other hygiene supplies.

Description

Liquid absorbing net face with excellent permeability energy

This utility model relates to a kind of liquid absorbing net face with excellent permeability energy.

At present, be used in the liquid absorbing net face in the products such as sanltary towel, baby diaper and medical bed mattress, generally all comprise upper strata liquid absorbing net face and lower floor's water accepting layer, and be covered with a plurality of flow liquid mesh on the described liquid absorbing net face.The orifice shapes of the flow liquid mesh on the existing liquid absorbing net face has circle, hexagon and pentagon, and described hexagon mesh and pentagon mesh all can extend downwards and be infundibulate.

The quality of liquid absorbing net face quality depends on that this wire side liquid oozes the height of the rate of prolonging, it is high more to ooze the rate of prolonging, the quality of liquid absorbing net face is good more, and the rate of prolonging of oozing of liquid absorbing net face is to be directly proportional with the girth of opening sky rate and mesh on the wire side, and circular mesh, hexagon mesh and pentagon mesh to ooze the rate of prolonging all undesirable, and the present domestic equipment of not producing liquid absorbing net face as yet, therefore, domestic employed liquid absorbing net face can only depend on import now.

The purpose of this utility model is will provide a kind of liquid to ooze to prolong rate height, fast, the anti-good homemade liquid absorbing net face of performance that bleeds back of drain age velocity.

The purpose of this utility model is achieved in that this liquid absorbing net face, be on its wire side, to be covered with a plurality of miniature mesh, this miniature mesh is infundibulate to the extension of wire side below, the orifice shapes that it is characterized in that described miniature mesh is tetragon, on the wire side between described adjacent miniature mesh and the miniature mesh, be equipped with the convex surface of projection above wire side, wire side around each convex surface is all downward-sloping, forms the continuous flow liquid slope, aperture of a plurality of miniature mesh around being adjacent.

Liquid absorbing net face described in the utility model, because described mesh is made quadrangularly, opening on an equal basis under the sky rate situation identical with orifice area, the girth of quadrilateral hole compares circular hole, the girth in hexagonal hole and pentagon hole all will be grown, therefore, liquid absorbing net face described in the utility model oozes the rate of prolonging for the highest; Again because this utility model is provided with convex surface on described wire side, the flow liquid slope that the aperture of a plurality of miniature mesh around all downward-sloping formation of wire side around each convex surface is adjacent links to each other, therefore liquid absorbing net face described in the utility model also has the fast advantage of drain age velocity.And liquid absorbing net face described in the utility model is to produce with home equipment, so this utility model has been filled up domestic blank.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the front view of liquid absorbing net face described in the utility model.

Fig. 2 is the upward view of Fig. 1.

Fig. 3 is the left view of Fig. 1.

Describe the structure of the concrete liquid absorbing net face that the utility model proposes in detail below in conjunction with Fig. 1～Fig. 3.

This liquid absorbing net face is to be covered with a plurality of miniature mesh 2 on this wire side 1, this miniature mesh 2 is infundibulate to the extension of wire side below, the orifice shapes of described miniature mesh 2 is tetragon, on the wire side 1 between described adjacent miniature mesh 2 and the miniature mesh 2, be equipped with the convex surface 1-1 of projection above wire side 1, wire side around each convex surface 1-1 is all downward-sloping, forms the continuous flow liquid slope 1-2 of aperture 2-1 of a plurality of miniature mesh 2 around being adjacent.

The aperture 2-1 of described miniature mesh can be rectangle, square or rhombus.

Aperture, the lower end 2-2 of described miniature mesh can be burr.

This utility model is widely used in sanltary towel, baby diaper, medical bed mattress and other hygienic article.
