Description

Non-woven fabric capable of preventing lateral water leakage

Technical Field

The utility model relates to a non-woven fabrics field especially relates to a prevent non-woven fabrics that side direction leaked.

Background

Nonwoven fabrics are fabrics comprised of oriented or random fiber web layers that are mechanically entangled with one another to provide increased strength between the fiber web layers. The non-woven fabric has the advantages of air permeability, flexibility, light weight, low price, easy degradation and the like, and is widely applied to various industries.

Because the ES fiber has the characteristics of low melting point, good flexibility, high melting point of core layer tissues and high strength, the ES fiber is widely applied to the inner layer of the non-woven fabric.

However, the water pressure resistance of the ES fiber is generally, water drops may flow along the surface of the ES fiber, causing water leakage in the inner side of the nonwoven fabric, and the performance index of some nonwoven fabrics used as desiccant packing materials is still difficult to meet the requirement.

SUMMERY OF THE UTILITY MODEL

The utility model is not enough to prior art, the utility model aims at providing a prevent non-woven fabrics that side direction leaked to it is not enough with waterproof performance to solve among the prior art non-woven fabrics water-resistant pressure, especially easy inside problem that the side direction leaked appears, and specific technical scheme is as follows:

the utility model provides a prevent non-woven fabrics of side direction leaking, includes PET layer and ES fibrous layer, still includes PP rete and PE rete, be connected through the viscose between PP rete and the PET layer, PE rete area is greater than the area of PP rete and cladding in the PP rete, the PE rete passes through the viscose and connects in the edge of the one side of PP rete and another side, the PE rete with it is compound through the hot melt between the ES fibrous layer.

Further: and a plurality of salient points vertical to the surface of the PET layer are arranged outside the PET layer.

Further: the salient points are oblate salient points.

Further: the thickness of the PP film layer is 15-40um.

Further: the thickness of the PP film layer is 20-30um.

Compared with the prior art, the beneficial effects of the utility model are that: through having set up the PP rete, increased the water resistance of non-woven fabrics, seamless connection between PE rete and the PP rete to utilized the low characteristics of PE rete melting point, it is heated and is fused with the ES fibrous layer, prevents the condition of the inside surface horizontal side leakage of ES fibre.

Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, the utility model is further explained by combining the specific implementation mode.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, for the structural schematic diagram of the present invention, a non-woven fabric for preventing lateral water leakage, which comprises a PET layer 1, a PP film layer 2, a PE film layer 3 and an ES fiber layer 4 in sequence from outside to inside. The tensile strength on PET layer is big, and high temperature resistant, is fit for as outer protection non-woven fabrics, and the middle level is the PP rete, has good water pressure resistance, guarantees that the non-woven fabrics is difficult to vertically leak, is connected through the gluing agent between PP membrane and the PET layer.

The inboard PE rete 3 that is of PP rete 2, the inboard of PE rete 3 cladding in PP rete 2, the edge in the inboard and the outside of PP rete 2 all with the adhesion of PE rete 3 for PP rete 2 and 3 seamless connection of PE rete, because the PE rete is comparatively frivolous material, so set up the thickness influence to whole non-woven fabrics little.

Because the PE film layer 3 has low melting point and is heated to be easily fused with the inside ES fiber layer 4, the problem that the surface of the ES limiting layer 4 is easy to leak water transversely is effectively solved, and the transverse and longitudinal waterproof performance of the non-woven fabric is improved.

In some embodiments, the outside of the PET layer is further provided with oblate bumps 11 to increase friction and make the nonwoven fabric more compact.

Since the PE film layer 3 also has a certain water pressure resistance, compared to the conventional waterproof PP film, the thickness of the PP film layer 2 in this embodiment can be selected to be thinner so that the whole nonwoven fabric is thinner, and the thickness of the PP film layer ranges from 15 um to 40um, preferably from 20 um to 30um.

The non-woven fabric has good transverse and longitudinal waterproof performance, can be used as a desiccant packaging material and the like, has low manufacturing cost and is suitable for popularization.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
