Description
Technical Field
The invention relates to an antibacterial and antivirus silk fiber filter base cloth and application thereof, and belongs to the field of medical protective materials.
Background
The mask is a sanitary article, generally refers to an appliance worn at the mouth and nose part for filtering air entering the mouth and nose so as to prevent harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer, and is mainly made of chemical fiber materials or cotton fabrics and other materials as base cloth. The mask has a certain filtering effect on air entering the lung through the respiratory system of the body, and has a very good effect when the mask is worn during operation in the environment polluted by dust and the like when respiratory infectious diseases are prevalent. The main uses of the common mask are as follows: the mask has the main purposes of facial modification, sunscreen effect, dental medical correction, skin covering, face warm keeping, air (dust) pollution prevention, respiratory infectious virus prevention and the like, wherein the air (dust) pollution prevention and the respiratory infectious disease prevention are the main purposes of the mask.
The types and the main functions of the common mask at present are as follows:
common gauze mask: civil use, belongs to the textile class. The common gauze mask is a cotton fiber mask, the flow blocking principle of the gauze mask is a mechanical blocking effect, large particles can be blocked by one layer of mechanical blocking, but particles with the diameter smaller than 5 microns cannot be blocked.
Medical mask: the medical mask is mainly made by compounding one or more layers of non-woven fabrics, mainly produced by melt-blowing, spun-bonding, hot air or needling and the like, has the effects of resisting liquid, filtering particles, bacteria and the like, and is a textile for medical protection.
Daily protective mask: the antifog haze of mainly used.
Dust mask, and oil smoke mask (scientific name: self-priming filtering type particulate matter-proof respirator).
Generally used for occupational protection. The anti-haze effect is better.
(a) The dust mask is mainly used for preventing dust, smoke, fog, microorganisms and the like. Grades are KN100, KN95 and KN 90. Wherein the KN100 grade can effectively prevent the ultrafine dust rate by more than 99.97%.
(b) The fume-proof mask is mainly used for preventing fume and oil mist and simultaneously preventing dust, smoke, mist, microorganisms and the like. The grades are KP100, KP95 and KP 90. Wherein KP100 grade can effectively prevent the ultrafine dust rate by more than 99.97 percent.
Wherein the filtering layers of the medical mask, the anti-haze mask and the KN95 type dust-proof and microorganism mask are made of polypropylene fiber materials, and the porous multilayer fiber base cloth is prepared by a melt-blown spinning non-woven fabric production process. The diameter of the fiber obtained by the melt-blowing method is generally between several micrometers and more than ten micrometers, and the superfine fiber is disorderly arranged after non-woven. The non-woven base fabric has the characteristics of three-dimensional microporous structure, large specific surface area, small aperture, high porosity, high efficiency, low resistance and the like, so that the material is widely applied to manufacturing of protective masks. Due to the random arrangement of the superfine fibers and the crossed interlayer, a narrow and thin multi-bending channel structure is formed on the base cloth layer, so that particulate matters (such as haze in air, new coronavirus-containing droplets, aerosol and the like) can collide with the fibers and are adsorbed and retained.
As can be seen from the microstructure of the materials of fig. 1 and 2 (the microstructure of the nonwoven fibers is shown in fig. 1, and the microstructure of the conventional scrim is shown in fig. 2): the traditional gauze base cloth is formed by original warp and weft weaving, gaps among fibers are large, most of gap channels do not have a multi-bending channel structure, so that the retention and filtration effects are poor, and the gauze base cloth can only be used for producing common gauze masks; however, the non-woven fiber base cloth has a random cross interpenetrating network structure due to the fiber space morphology, the fiber gaps are very small, and the three-dimensional microporous structure enables most of the gap channels to have a multi-bending channel morphology, so that the blocking and filtering effects are high, the blocking and filtering effects on various common pollutants in the air are good, and the non-woven fiber base cloth is very suitable for the production of mask filtering layer base cloth for medical protection and the like.
However, the polypropylene chemical fiber is limited by the chemical structure of the high molecular chain segment, the surface of the fiber has no any polar active chemical group, the fiber can not be chemically modified by the conventional chemical reaction method, and the surface of the fiber can not be endowed with multiple functionalities (such as electropositivity, chemical reaction adsorption, moisture absorption and the like), so that the multilayer non-woven base fabric prepared by the material fiber in a non-woven mode can only block and adsorb harmful particles (such as haze, droplet containing new crown virus, aerosol and the like in the air) in a single physical mode to achieve the effect of effective filtration, and the material is not hydrophilic, in the use of the mask, because the water vapor generated in the breathing process can not be adsorbed and absorbed very much, and the gap between the face and the mask can be overflowed to influence the vision of a wearer (the wearing of glasses is serious), and the physical and chemical affinity of the chemical fiber material with the skin is poor, it is also likely to cause a feeling of discomfort to the skin.

On the other hand, the surface of the silk fiber is endowed with a plurality of considerable active groups, and the functions of electropositivity, chemical reactivity, chemical adsorption and the like can be endowed to the surface of the protein fiber by combining chemical functional group modification. Wherein, the quaternary ammonium salt of the compound A is grafted by the reaction of epoxy group and amino group on the molecular chain of protein fiber; the compound B can react with amino groups on the molecular chains of the protein fibers to perform cross-linking among the molecular chains of the protein fibers. Finally, the cationic groups are grafted on the surface of the protein fiber, so that the surface of the fiber has strong electropositivity, the growth and the propagation of bacteria can be inhibited, and the antibacterial effect is achieved.

Other polar functional groups (carboxyl, hydroxyl, peptide bonds and the like) of the silk fiber can also generate chemical adsorption effect on pollutants in the air, microbial viruses and the like through electrovalence bonds, hydrogen bonds and chemical acting force among various molecules. The functional effects are combined with the physical effects of the gaps and the multi-bending channels of the three-dimensional microporous structure of the base cloth, and the effects of various physical and chemical modes and the like are superposed to further strengthen the high blocking and filtering effects of the base cloth, so that the base cloth has good blocking and filtering effects on various common pollutants in the air.
