Embodiment Construction
[0012] figure 1 It is a structural representation of the present invention. As shown in the figure, the functional breathable film composite non-woven fabric 10 is composed of a functional non-woven fabric 1 and a breathable film 2. The multifunctional composite non-woven fabric 1 is composed of four layers of materials. The outermost and innermost layers of the cloth are the functional layer and the second polypropylene layer (8, 3), and below the functional layer is the first polypropylene layer 4, between the first polypropylene layer 4 and the second polypropylene layer 3 There is a thermoplastic elastomer polypropylene core layer 5 in between; there is also a permeable layer (6, 7) at the junction of the thermoplastic elastomer polypropylene core layer 5 and the first and second polypropylene layers (3, 4), and the functional layer 8 also has a permeable layer (71) at the junction of the polypropylene layer.
[0013] The breathable membrane 2 is compounded on the second...

A functional breathable film composite nonwoven cloth consists of a glue layer, a composite nonwoven cloth and a breathable film. The composite nonwoven cloth is composited by a functional layer, a first polypropylene layer, a thermoplastic elastomer polypropylene core layer and a second polypropylene layer. The functional layer is arranged on a most outer layer of the nonwoven cloth; the second polypropylene layer is arranged in a most inner layer of the nonwoven cloth; the first polypropylene layer is disposed under the functional layer; the thermoplastic elastomer polypropylene core layer is arranged between the first polypropylene layer and the second polypropylene layer; the breathable film is composited onto the second polypropylene layer; and the glue layer is disposed between the breathable film and the second polypropylene layer. The functional breathable film composite nonwoven cloth is a special high-molecular nonwoven material which has special functions and structure. The functional breathable film composite nonwoven cloth is small in fiber diameters, is good in breathability, flexibility and wear-proofing performance, is free of combustion-supporting property and is free of toxin and irritation. A problem of limited application of the nonwoven cloth in medicinal protective clothing due to a poor water-proof performance of the nonwoven cloth is improved.
Description
technical field [0001] The invention relates to a composite non-woven fabric, in particular to a non-woven fabric composed of a melt-blown cloth and a breathable film. Background technique [0002] Breathable film, referred to as breathable film, is a film that can pass through air and gas, but can block liquids like water. It is a functional material, also known as "Breathable-Film", which is usually used in occasions that require both breathability and waterproof. At present, breathable membranes are widely used in health, medicine, construction, automobile and sports industries, and the products produced by them involve baby diapers, adult incontinence pants, nursing products and women's hygiene products; medical protective products, hospital anti-allergic bedding; protective clothing, work clothing and their lining materials; roof protection materials and breathable waterproof materials, etc. [0003] Non-woven fabric, also known as non-woven fabric, has the characteri...
