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 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 woven ...

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 as well as a production method and application thereof. The multifunctional protective material comprises an isolation layer, an adsorptionlayer, a filtering layer, a medicine carrying layer and a skin-friendly layer which are sequentially arranged in a stacked mode, wherein the adsorption layer is woven cloth containing non-woven fabric strip wrap yarn with built-in high-adsorption-function particles, and the medicine carrying layer is woven cloth containing non-woven fabric strip wrap yarn with built-in medicine blasting beads. Bymeans of the arrangement, on one hand, toxic gas is effectively adsorbed through the adsorption layer, cloth flexibility of the anti-virus material is achieved, and invasion of nanoscale viruses is blocked from the outer side through the filtering layer; and on the other hand, through the blasting beads in the medicine carrying layer and blocking of the filtering layer, the medicine is guided into the human body in a one-way mode, meanwhile, a user can apply external force to the protective material according to needs so as to release the medicine in the medicine carrying layer, and the medical function is achieved. The multifunctional protective material has multiple functions of gas prevention, haze prevention, bacteria resistance, bacteriostasis and the like, and can be used for gas-proof antibacterial 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), the spread of Middle East Respiratory Syndrome (MERS) in South Korea, and the recent outbreak of respiratory infectious diseases caused by novel co...
