Abstract
The invention discloses a high-strength water-resistant breathable non-woven fabric which comprises a first non-woven fabric layer, a reinforced water-resistant breathable layer and a second non-woven fabric from top to bottom in sequence, wherein the reinforced water-resistant breathable layer is a glass fiber reinforced polyethylene film layer; a plurality of breathing holes are uniformly formed in the glass fiber reinforced polyethylene film layer. The high-strength water-resistant breathable non-woven fabric disclosed by the invention is simple in structure, reasonable in design, efficient in water resistance and relatively good in practicability; due to the structural design of a reinforced breathing layer, on one hand, the structural strength of the non-woven fabric is improved, and on the other hand, air flow can be circulated inside and outside the non-woven fabric.
Description
Technical field
The present invention relates to non-woven fabrics field, particularly relate to a kind of high-strength Breathable nonwoven that blocks water.
Background technology
Non-woven fabrics (English name: Non Woven Fabric or Nonwoven cloth) is also known as adhesive-bonded fabric, it is to be made up of that orient or random fiber, it is a new generation's environment-friendly materials, there is protection against the tide, ventilative, pliable and tough, light weight, decomposition the most combustion-supporting, easy, nontoxic nonirritant, rich color, the feature such as use again cheap, capable of circulation.It is raw material as used polypropylene (pp material) pellet more, batches continuous one-step produce through high-temperature fusion, spray webbing, paving guiding principle, hot pressing.It is called cloth because having the outward appearance of cloth and some performance.
In use, mostly there is structural strength low in existing non-woven fabrics, the shortcoming such as weigh little, uses as load-bearing bag and is very restricted.And non-woven fabrics itself does not blocks water, easy moisture absorption or non-watertight, the article held in it are not had the effect of the protection that blocks water.Existing part non-woven bag, by realizing waterproof function at outer surface marine glue, but also sacrifices the breathability feature that non-woven fabrics itself is had simultaneously.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of high-strength Breathable nonwoven that blocks water, it is possible to solve the problems referred to above that existing non-woven fabrics exists.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provides a kind of high-strength Breathable nonwoven that blocks water, includes the most successively: the first nonwoven layer, enhancement mode block water air-permeable layer and the second nonwoven layer；Wherein, described enhancement mode waterproof ventilative layer is the polyethylene film layer of glass fiber reinforcement, with multiple equally distributed air-vents on it.
In a preferred embodiment of the present invention, the thickness of described enhancement mode waterproof ventilative layer is 0.05～0.15mm, and the diameter of described air-vent is more than the diameter of single water vapour molecule, less than the diameter of hydrone.
In a preferred embodiment of the present invention, in described enhancement mode waterproof ventilative layer, the percentage by weight of glass fibre is 5～15%.
In a preferred embodiment of the present invention, described enhancement mode blocks water and is additionally provided with one layer of reinforcing fiber net between air-permeable layer and the second nonwoven layer.
In a preferred embodiment of the present invention, described reinforcing fiber net is bamboo fibre or wood fiber net, and its grid is rectangle, square or rhombus.
In a preferred embodiment of the present invention, the Mesh Diameter of described reinforcing fiber net is 1～5cm.
The invention has the beneficial effects as follows: a kind of high-strength Breathable nonwoven that blocks water of the present invention, simple in construction, reasonable in design, it is designed by the structure strengthening air-permeable layer, on the one hand improve the structural strength of non-woven fabrics, on the other hand ensure non-woven fabrics internal with the external world can vent flow mutually, while efficiently block water, practicality is stronger.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of high-strength Breathable nonwoven embodiment 1 that blocks water of the present invention；
Fig. 2 is the perspective view of a kind of high-strength Breathable nonwoven embodiment 2 that blocks water of the present invention；
Fig. 3 is the structural representation of shown reinforcing fiber net；
In accompanying drawing, the labelling of each parts is as follows: 1. the first nonwoven layer, 2. enhancement mode waterproof ventilative layer, 3. the second nonwoven layer, 4. air-vent, 5. reinforcing fiber net.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to Fig. 1-3, the embodiment of the present invention includes:
Embodiment 1
A kind of high-strength Breathable nonwoven that blocks water, includes the most successively: the first nonwoven layer 1, enhancement mode block water air-permeable layer 2 and the second nonwoven layer 3.
Wherein, the first nonwoven layer 1 and the second nonwoven layer 3 are spun-bonded non-woven fabrics.
The polyethylene film layer that enhancement mode waterproof ventilative layer 2 is glass fiber reinforcement that thickness is 0.05～0.15mm, the percentage by weight of glass fibre is 5～15%, with multiple equally distributed air-vents 4 on this enhancement mode waterproof ventilative layer 2, the diameter of air-vent 4 is more than the diameter of single water vapour molecule, diameter less than hydrone, so that the water in the external world can not enter in nonwoven fabric belts, simultaneously in non-woven fabrics can to realize steam penetrating with the external world, thus realize ventilative purpose.
Embodiment 2
Difference with embodiment 1 is, enhancement mode blocks water and is additionally provided with one layer of reinforcing fiber net 5 between air-permeable layer 2 and the second nonwoven layer 3, and its material is bamboo fibre or wood fiber net, and the grid of fleece is rectangle, square or rhombus, and Mesh Diameter is 1～5cm.
Non-woven fabrics really is played and strengthens the effect supported by fleece.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
