Technical Field

The invention relates to the field of non-woven fabrics, in particular to a radiation-proof non-woven fabric with a good filtering effect and a preparation process thereof.

Background

The radiation-proof fabric is mainly composed of five kinds, only one of the five kinds is described above, and the radiation-proof fabric is generally called metal fiber radiation-proof fabric; besides the fabric, the market is popular with a multielement fabric, a copper or nickel ion fabric, a silver fiber fabric and a one-way antistatic fabric. The metal fine wires are spun by metal micro-wires with the diameter of 3-50 microns, the silver fiber fabric is a material which is more utilized, but the radiation protection effect of the radiation protection clothes made of the existing silver fibers is poor.

Disclosure of Invention

In order to solve the defect that the radiation protection effect of the existing radiation protection fabric is poor, the invention provides a radiation protection non-woven fabric with a good filtering effect and a preparation process thereof.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a radiation protection non-woven fabrics that filter effect is good and preparation technology thereof, is radiation protection layer in the middle of it, radiation protection layer is woven for the horizontal silver system silk thread of diameter 0.01-0.05 millimeter and the vertical silver system silk thread of diameter 0.01-0.05 millimeter and forms, horizontal silver system silk thread and vertical silver system silk thread all adopt the silver-copper alloy material that contains silver content 20% -30%, radiation protection in situ both sides are equipped with the melt-blown layer, the material of melt-blown layer is superfine polypropylene fiber melt-blown material, the outside of melt-blown layer is equipped with waterproof filter layer, waterproof filter layer material is polyester staple fiber and cotton according to 60% -70%: 30-40% of the above-mentioned materials.

The preparation process of the radiation-proof non-woven fabric with good filtering effect comprises the following steps:

preparing raw materials in proportion according to production requirements;

weaving silver silk threads into an anti-radiation layer, and arranging a melt-blown layer outside the anti-radiation layer through a melt-blowing machine;

and step three, sticking a waterproof filter layer outside the melt-blown layer by an anti-sticking method.

As can be seen from the above, the present invention has the following advantages compared with the prior art:

according to the radiation-proof non-woven fabric with the good filtering effect and the preparation process thereof, the radiation-proof layer is formed by weaving silver threads made of silver-copper alloy, so that radiation protection can be effectively achieved, the silver-copper alloy is good in oxidation resistance effect, a silver product can be sterilized, the melt-blown layer made of superfine polypropylene fiber melt-blown material and arranged outside the radiation-proof layer can effectively resist virus and bacteria, the waterproof filter layer arranged outside the melt-blown layer can effectively prevent water from entering, and the radiation-proof non-woven fabric can effectively resist radiation damage, and can also be used for sterilizing, resisting virus and preventing water.

Drawings

Fig. 1 is a schematic structural view of the present invention.

In figure 1, the radiation protection layer is 1, the melt-blown layer is 2, and the waterproof filter layer is 3.

Detailed Description

As shown in figure 1, the radiation-proof non-woven fabric with good filtering effect and the preparation process thereof are composed of a radiation-proof layer 1, a melt-blown layer 2 and a waterproof filter layer 3, wherein the radiation-proof layer 1 is arranged in the middle, the radiation-proof layer 1 is formed by weaving transverse silver silk threads with the diameter of 0.01-0.05 mm and longitudinal silver silk threads with the diameter of 0.01-0.05 mm, the transverse silver silk threads and the longitudinal silver silk threads are both made of silver-copper alloy materials with the silver content of 20% -30%, the melt-blown layer 2 is arranged on the inner side and the outer side of the radiation-proof layer 1, the melt-blown layer 2 is made of superfine polypropylene fiber melt-blown materials, the waterproof filter layer 3 is arranged outside the melt-blown layer 2, and the waterproof filter layer 3 is made of polyester staple fibers and cotton: 30-40% of the above-mentioned materials.

The preparation process of the radiation-proof non-woven fabric with good filtering effect comprises the following steps:

preparing raw materials in proportion according to production requirements;

weaving silver silk threads into an anti-radiation layer, and arranging a melt-blown layer outside the anti-radiation layer through a melt-blowing machine;

and step three, sticking a waterproof filter layer outside the melt-blown layer by an anti-sticking method.
