Meltblown cloth, non-woven fabric and mask
Melt-blown cloth and mask
Melt-blown cloth is the core fabric of medical masks, commonly known as the 'heart' of the mask. It is the filter layer in the middle of the mask, which can filter bacteria and prevent the spread of germs. Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1-5 microns. With many voids, fluffy structure and good wrinkle resistance, these ultra-fine fibers with unique capillary structure increase the number and surface area of u200bu200bfibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption. . It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil absorbing materials and wiping cloths and other fields.
Scope of application
(1) Medical and sanitary cloths: surgical gowns, protective clothing, sterile wraps, masks, diapers, women's sanitary napkins, etc.;
(2) Home decoration fabrics: wall coverings, tablecloths, bed sheets, bedspreads, etc; Base cloth, etc.;
(4) Industrial cloth: filter material, insulating material, cement packaging bag, geotextile, wrapping cloth, etc.;
(5) Agricultural cloth: Crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc;
Main features
The filter material of melt-blown cloth is randomly distributed and bonded together by polypropylene microfibers. The appearance is white, smooth and soft, and the material fiber fineness is 0.5-1.0 μm, the random distribution of fibers provides more opportunities for thermal bonding between fibers, thus making the meltblown gas filter material have a larger specific surface area and a higher porosity (≥75%). After high-pressure electret filtration efficiency, the product has the characteristics of low resistance, high efficiency, and high dust holding capacity.
Non-woven fabrics and masks
Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. It is called cloth because of its appearance and certain properties.
The mask is a multi-layer composite structure. The N95/KN95 mask consists of the innermost and outermost non-woven layers, the middle electrostatic layer and the melt-blown non-woven layer. The medical surgical mask is a non-woven fabric. cloth layer and meltblown non-woven layer. In addition to supporting the mask, the non-woven layer also acts as a part of the sieve, and particles with large particle sizes will be blocked by them.
Non-woven fabrics are moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are used as raw materials, and are produced by a continuous one-step method of high temperature melting, spinning, laying, and hot pressing and coiling.
Features of non-woven fabrics
Non-woven fabrics have no warp and weft threads, so they are very convenient to cut and sew, and are light in weight and easy to shape. Because it is a fabric that does not require spinning or weaving, it just orients or randomly arranges textile staple fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical methods to reinforce it.
It is not intertwined and braided by yarns one by one, but the fibers are directly bonded together by physical methods, so when you get the adhesive in your clothes, When weighing, you will find that there is no thread that can be pulled out. Nonwovens break through the traditional textile principles, and have the characteristics of short process flow, fast production rate, high output, low cost, wide application, and many sources of raw materials.
The relationship between non-woven fabrics and spunbond fabrics
Spunbond fabrics and non-woven fabrics are subordinate. There are many production processes for the manufacture of non-woven fabrics, of which spunbond is one of the non-woven production processes (including spunbond, meltblown, hot rolling, spunlace, most of which are currently on the market). non-woven fabrics produced by the spunbond method).
According to the ingredients, non-woven fabrics include polyester, polypropylene, nylon, spandex, acrylic, etc.; different ingredients will have completely different styles of non-woven fabrics. The spunbond fabric usually refers to polyester spunbond and polypropylene spunbond; and the styles of these two kinds of fabrics are very similar, and can only be judged by high temperature test.

Advantages of graphene non-woven fabrics
1. Antibacterial and bacteriostatic functions
The unique two-dimensional structure of mineral graphene enables it to interact with bacteria on bacterial cell membranes. Phospholipid molecules have a strong dispersive interaction. When graphene contacts the bacterial cell membrane, it can induce the phospholipid molecules on the cell membrane to detach from the cell and climb the surface of the biomass graphene, so as to realize the effect of graphene on the phospholipid molecules on the cell membrane. Large-scale direct extraction, thereby destroying the cell membrane of bacteria, killing bacteria through physical action.
2. Far-infrared function
Graphene's far-infrared function can absorb more than 88% of far-red light with a wavelength of 6-14 microns at a low temperature of 20-35 degrees , helps to accelerate the temperature of the skin surface, dilate the capillaries, and improve the microcirculation of the body. Can be used for medical protective gear - protective clothing, surgical gowns, masks, hats, etc.
