Embodiment Construction

[0013] Such as figure 1 As shown, a radiation-proof non-woven fabric with good filtering effect and its preparation process 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 in the middle, and the radiation-proof layer 1 has a diameter of 0.01 ——0.05 mm horizontal silver wire and 0.01-0.05 mm diameter vertical silver wire are braided. Both the horizontal silver wire and the vertical silver wire are made of silver-copper alloy material with a silver content of 20%-30%, anti-radiation The inner and outer sides of layer 1 are provided with a melt-blown layer 2. The material of the melt-blown layer 2 is an ultrafine polypropylene fiber melt-blown material. The outer surface of the melt-blown layer 2 is provided with a waterproof filter layer 3. The material of the waterproof filter layer 3 is polyester staple fiber and Cotton is mixed according to the ratio of 60%-70%: 30%-40%.

Abstract

The invention relates to the field of non-woven fabrics, and discloses an anti-radiation non-woven fabric with a good filtering effect and a preparation process thereof. The anti-radiation non-woven fabric is provided with an anti-radiation layer in the middle, melt-blown layers are arranged on the inner side and the outer side of the anti-radiation layer, and waterproof filtering layers are arranged outside the melt-blown layers. The preparation process comprises the following steps: preparing the raw materials in proportion according to production requirements, arranging melt-blown layers outside an anti-radiation layer through a melt-blowing machine, and pasting a waterproof filter layer outside each melt-blown layer through an anti-sticking method. The anti-radiation non-woven fabric can effectively resist radiation hazards, and also can sterilize, resist viruses and resist water.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a radiation-proof non-woven fabric with good filtering effect and a preparation process thereof. Background technique [0002] There are roughly five types of anti-radiation fabrics, the above is just one of them, usually called "metal fiber anti-radiation fabrics"; in addition to this kind of fabrics, the more popular on the market are multi-element fabrics, copper or nickel ion fabrics, Silver fiber fabric, one-way anti-static fabric. Thin metal wire adopts the metal filament spinning between 3-50 microns in diameter, and silver fiber fabric is a kind of material that utilizes more, but the anti-radiation effect of the anti-radiation clothing that existing silver fiber is made is not good. Contents of the invention [0003] In order to solve the problem of poor radiation protection effect of existing radiation protection fabrics, the invention provides a radiation protection...
