Problems solved by technology
[0004] At present, non-woven fabrics and melt-blown fabrics are widely used in protective fields such as masks or medical protective clothing. It is the patient's blood that enters the protective clothing, which leads to cross-infection, especially in the process of contacting patients with highly infectious diseases or during surgery, the probability of cross-infection will be higher, which is harmful to medical staff and patients health threat

Embodiment 1-20
[0045] Example 1-20, a medical non-woven fabric for preventing cross-infection, its components and corresponding parts by weight are shown in Table 1, and the preparation steps are as follows:
[0046] S1: Material pretreatment, dissolving superabsorbent resin in ethanol solvent, stirring to obtain resin dispersion; adding sodium nitrate to resin dispersion, stirring and mixing, drying and cooling to obtain sweat-absorbing layer raw materials; mixing polypropylene fiber and polyacrylic acid Stir for 0.5-1h to obtain the protective layer raw material;
[0047] S2: Slicing the sweat-absorbing layer raw material and the protective layer raw material respectively to obtain resin slices and fiber slices;
[0048] S3: Raw material dissolution: Process the fiber slices and resin slices to a molten liquid state, keep warm and filter to obtain fiber stock solution and resin stock solution;
[0049] S4: Spinning cooling, the fiber stock solution and gel stock solution are extruded thro...

Abstract
The invention relates to the field of non-woven fabrics, and specifically discloses a medical non-woven fabric for preventing cross-infection and a preparation method thereof. The medical non-woven fabric for preventing cross-infection includes 40-80 parts of polypropylene fiber; 20-40 parts of polyacrylic acid; 5-10 parts of superabsorbent resin; 0-10 parts of sodium nitrate; 5-10 parts of adhesive; its preparation method It is: sweat-absorbing layer treatment, slicing treatment, raw material dissolution, spinning cooling, splitting and layout, outer layer reinforcement and bonding molding. The medical non-woven fabric for preventing cross-infection of the present invention has the advantage of preventing sweat from seeping out of the external blood to prevent cross-infection; in addition, the preparation method of the present invention has the advantage of simple and quick preparation.
Description
technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a method for preparing medical non-woven fabrics for preventing cross-infection. Background technique [0002] Non-woven fabric is a kind of fabric composed of oriented or random fibers that does not require spinning and weaving. It just arranges short textile fibers or filaments in an oriented or random manner to form a web structure, and then mechanically and thermally It is reinforced by adhesive or chemical methods. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. [0003] Melt blown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1-5 microns. There are many voids, fluffy structure, and good wrinkle resistance. The ultrafine fibers with unique capillary structure increase th...
