Problems solved by technology

[0003] During the use of existing non-woven fabrics, most of them have disadvantages such as low structural strength and small weighing weight, which greatly restrict their use as load-bearing bags.
Moreover, the non-woven fabric itself is not water-blocking, it is easy to absorb moisture or is not waterproof, and it does not have the effect of water-blocking protection for the items contained in it.
Some of the existing non-woven bags realize the waterproof function by coating the outer surface with waterproof glue, but at the same time, the air permeability characteristics of the non-woven fabric itself are sacrificed.

Embodiment 1

[0019] A high-strength water-blocking and breathable non-woven fabric, comprising: a first non-woven fabric layer 1 , a reinforced water-blocking and breathable layer 2 and a second non-woven fabric layer 3 from top to bottom.

[0020] Wherein, the first non-woven fabric layer 1 and the second non-woven fabric layer 3 are both spun-bonded non-woven fabrics.

[0021] The reinforced waterproof and breathable layer 2 is a glass fiber-reinforced polyethylene film layer with a thickness of 0.05-0.15mm, and the weight percentage of glass fiber is 5-15%. The hole 4, the diameter of the vent hole 4 is larger than the diameter of a single water vapor molecule and smaller than the diameter of a water molecule, so that the external water cannot enter the non-woven fabric belt, and at the same time, the non-woven fabric can realize water vapor penetration with the outside world, so that To achieve the purpose of ventilation.

Embodiment 2

[0023] The difference from Example 1 is that there is also a layer of reinforced fiber mesh 5 between the reinforced water-blocking and breathable layer 2 and the second non-woven fabric layer 3, which is made of bamboo fiber or wood fiber mesh, and the mesh of the fiber mesh is Rectangular, square or rhombus, the grid diameter is 1-5cm.

[0024] The fiber net plays a role in strengthening and supporting the whole non-woven fabric.

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 [0001] The invention relates to the field of non-woven fabrics, in particular to a high-strength water-blocking and breathable non-woven fabric. Background technique [0002] Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of oriented or random fibers and is a new generation of environmentally friendly materials. , non-toxic, non-irritating, rich in color, low in price, recyclable and so on. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. [0003] Most of the existing non-woven fabrics have disadvantages such as low structural strength and small weighing during use, and their use as load-bearing bags is greatly restricted. Moreover, the non-woven fabric itself is not wa...
