Embodiment 1

[0063] A multifunctional protective material, the preparation method is as follows:

[0064] (1) Prepare the non-woven strip package of isolation layer 1

[0065] Select surface density as 50g / m 2 The hemp medical antibacterial non-woven fabric is cut into 20cm wide non-woven fabric strips by FQJ automatic deviation-correcting strip slitting machine, and then wound on a cylindrical paper tube in parallel at a line speed of 125m / min to obtain an isolation layer 1 non-woven tape roll;

[0066] (2) Prepare the woven cloth strip package of adsorption layer 2

[0067] A PP non-woven fabric strip with a width of 10mm is used to wrap the carbon microspheres containing nanopores into a yarn. The mass fraction of the built-in carbon microspheres in the yarn body is 55%, and the fineness is 40tex. It is used as a weft yarn, and 21tex polyester is used. The sewing thread is used as the warp yarn, and the woven fabric with built-in carbon microspheres is made on the rapier loom. The wo...

Embodiment 2

[0077] A kind of multi-functional protection material, compared with embodiment 1, difference is that, in the process of the woven cloth strip package that prepares adsorption layer 2 in step (2), adopt built-in carbon microsphere mass fraction to be 55% 1. The PP non-woven strip covering yarn with a fineness of 200tex is used as the weft yarn, and the 21tex polyester sewing thread is used as the warp yarn, and the woven surface with built-in carbon microspheres is made on a rapier loom;

[0078] When step (4) prepares the strip package of drug-loaded layer 4, adopt the PP non-woven fabric strip that width is 12mm to wrap up ribavirin drug explosive bead into yarn, the ribavirin of yarn body The mass fraction of drug explosive beads is 30%, and the yarn fineness is 40tex, which is used as weft yarn, and 21tex polyester sewing thread is used as warp yarn, and a woven fabric with built-in interferon drug explosive beads is made on a rapier loom.

[0079] The rest of the steps ar...

Abstract

The invention provides a multifunctional protective material and its production method and application. The multi-functional protective material includes an isolation layer, an adsorption layer, a filter layer, a drug-loaded layer, and a skin-friendly layer that are stacked in sequence, and the adsorption layer is a woven fabric that contains a non-woven strip covered yarn with built-in high-adsorption function particles. The drug-loaded layer is a woven cloth containing non-woven fabric strips with built-in drug explosive beads. With such a setting, on the one hand, the adsorption layer effectively absorbs toxic gases, realizes the flexibility of the cloth of the anti-virus material, and blocks the invasion of nano-scale viruses from the outside through the filter layer; The barrier of the drug-loaded layer allows the drug to be introduced into the human body in one direction. At the same time, the user can apply an external force to the protective material to release the drug in the drug-loaded layer to achieve medical functions. The multi-functional protective material has multiple functions such as anti-virus, anti-smog, antibacterial, and antibacterial, and can be used for anti-virus and anti-bacterial masks or gas masks or medical protective clothing.

Description

technical field [0001] The invention relates to a multifunctional protective material and its production method and application, belonging to the technical field of protective articles and textiles. Background technique [0002] In daily life, harmful substances such as poisonous smoke released from fires, formaldehyde or infectious viruses released from newly renovated rooms are distributed in the air, suspended and flowed in the air, and after entering the human body through the mouth and nose, it is harmful to people's life, health and Security poses a huge threat. Especially in recent years, public health emergencies caused by new infectious viruses have gradually become the forefront of global security: the SARS epidemic from October 2002 to May 2003, and the subsequent bird flu (H5N1, H5N8, H7N7, H7N9), Influenza A (H1N1), Middle East Respiratory Syndrome (MERS) and the recent outbreak of respiratory infectious diseases caused by novel coronavirus (2019-nCoV). Emergi...
