Embodiment 1

[0059] See Figure 1 — Figure 5 , a medical protective taking adsorption antibacterial nonwoven fabric production apparatus, comprising a spinneret 1, a side cooling device 2, a drafting device 3 and a conveyor belt 4, the side cooling device 2 is provided with a cooling chamber 21, the drawing device 3 is provided with a drawing chamber 31, the bottom of the wire spray plate 1 is sequentially through the cooling chamber 21, the drafting chamber 31 after the top of the conveyor belt 4 is communicated; the part on the conveyor belt 4 opposite the bottom of the drafting chamber 31 is the laying section 531, the upstream of the laying section 531 is the incoming section 511, Downstream of the laying section 531 is a film-forming section 61, the upper part of the film-forming segment 61 is provided with a yin mist sprayer 62, the shadow fog sprayer 62 is provided at the bottom of the cloud fog sprayer 621 and the film-forming section 61 is set up and down, the incoming section 511, th...

Embodiment 2

[0062] The basic content is the same as Example 1, the difference is that:

[0063] The cationic polyelectrolyte is sodium alginate, hyaluronic acid, polyacrylic acid, polystyrene sulfonic acid, polyethylene sulfonic acid, polyethylene phosphoric acid in any one or any mixture;

[0064] The anionic polyelectrolyte is polypropyl hydrochloride, chitosan, polydivinyldimethylammonium chloride, polyethyleneimide, polyquaternium salt, polyvinylpyridine in any one or any mixture.

Embodiment 3

[0066] The basic content is the same as Example 1, the difference is that:

[0067] The oblique spray pipe 7 includes a diagonal spray executive 72 and an oblique spray low tube 73, the oblique spray executive 72 is higher than the oblique spray low pipe 73 is set, the number of the oblique spray executive 72 is at least two, the number of the oblique spray low pipe 73 is also at least two. Adjacent diagonal spray executive 72, oblique spray low tube 73 are parallel to each other. The diameter of the oblique spray executive 72 is less than the diameter of the oblique spray low pipe 73, all the oblique spray executive 72 is uniformly arranged along the same circumference, and all the diagonal spray low tube 73 is uniformly arranged along the same circumference.

Abstract

A production device for absorbing antibacterial nonwovens for medical protective clothing, including a spinneret, a side cooling device, a drafting device, and a conveyor belt, wherein the bottom of the spinneret passes through the cooling chamber, the drafting chamber, and the conveyor belt in sequence. The top is connected, and the part on the conveyor belt that is directly opposite to the bottom of the drafting chamber is the laying section. A horizontal line moves to the right together. The drafting device is provided with at least two obliquely downward spray pipes and at least two obliquely upward powder spray pipes. The obliquely lower spraying port of the pipe communicates with the drafting chamber, and the obliquely upper powdering port of the obliquely upper powder spraying pipe communicates with the drafting chamber, and the obliquely lowering spraying ports are all set higher than the obliquely upper powdering port. This design is not only easy to produce, not limited by the surface structure modification process, but also has antibacterial and adsorption functions.

Description

Technical field [0001] The present invention relates to a medical protective cloth nonwovens preparation process, belongs to the functional nonwovens preparation technology field, in particular to a medical protective cloth adsorption antibacterial nonwovens production device and process. Background [0002] The main role of medical protective clothing is to shield and block bacteria, body fluids, external infections, etc., in order to effectively isolate external viruses or pollution. With the rapid development of modern industry, the destruction of nature by human beings has intensified, and pollution has become increasingly serious, resulting in the reproduction and spread of various germs, for this reason, the requirements for the protective performance of protective clothing fabrics are also getting higher and higher, of which antibacterial performance is a very important indicator. Therefore, the development of antibacterial nonwovens is of great significance. SMS composit...
