Anti-bacterial and anti-virus silk fiber filtering base cloth and application thereof

Abstract

The invention discloses anti-bacterial and anti-virus silk fiber filtering base cloth. The base cloth is characterized in that a preparation method includes the following step that grafting treatmentis performed on silk spunlace non-woven cloth subjected to glue solidifying treatment by the aid of a compound A and a compound B; the compound A is epoxy propyl-trimethyl ammonium chloride; and the compound B is a pickling-free chrome-free tanning agent TWS produced by the Sichuan Tingjiang New Material Co., LTD. The base cloth has the hygroscopicity and can adsorb moisture produced by human breathing, so that the vision of a wearer is not affected. Protein coatings are formed on the surfaces of the fibers, so that the mechanical strength is enhanced, and the filtering effect is enhanced. Through grafting of the compound A and the compound B, the base cloth has the good anti-bacterial and anti-virus effects and is good making materials for masks and medical protective clothing.

Description

technical field [0001] The invention relates to an antibacterial and antivirus silk fiber filter base cloth and an application thereof, belonging to the field of medical protective materials. Background technique [0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose, mainly made of chemical fiber materials or cotton fabrics, etc. The material is made of base cloth. The mask has a certain filtering effect on the air entering the lungs through the respiratory system of the body. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. The main uses of general masks are: modifying face shape, anti-sunshine effect, dental medical correction, covering skin texture, keeping face warm, preventing air (dust) ...

AI Technical Summary

Problems solved by technology

[0013] However, this kind of polypropylene chemical fiber is limited by the chemical structure of the polymer segment itself, and the surface of the fiber does not have any polar active chemical groups. It cannot be chemically modified by conventional chemical reaction methods, and it is impossible to endow this type of fiber with The surface has a variety of functions (positive electricity, chemical reaction adsorption, moisture absorption, etc.), so the multi-layer non-woven base fabric prepared by the non-woven method of this kind of material fiber is not harmful to harmful particles (such as smog in the air, flying particles containing new crown virus, etc.) Foam and aerosol, etc.) only achieve effective filtration through a single physical barrier and adsorption, and because the material itself is not hydrophilic, the water vapor generated during the breathing process cannot be even absorbed during the use of the mask. The overflow from the contact gap between the face and the mask will affect the vision of the wearer (especially when wearing glasses), and this kind of chemical fiber material has poor physical and chemical affinity with the skin, and it is easy to cause skin discomfort
