Meltblown cloth and mask
Meltblown cloth is the core fabric of medical masks, commonly known as the 'heart' of the mask, and is the filter layer in the middle of the mask, which can filter bacteria and prevent the spread of germs. Melt blown cloth is mainly made of polypropylene, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, and good anti-wrinkle ability. 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 filtration, 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.
Application scope
(1) Medical and sanitary cloths: surgical gowns, protective clothing, disinfection wraps, masks, diapers, sanitary napkins, etc.;
(2) Home decoration cloth: wall cloth, table cloth, bed sheet, bedspread, etc.;
(3) Clothing fabrics: lining, adhesive lining, wadding, shaped cotton, various synthetic leather base fabrics, etc.;
(4) Industrial cloth: filter material, insulating material, cement packaging bag, geotextile, covering cloth, etc.;
(5) Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.;
(6) Others: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc.
Main features
Meltblown cloth filter material is made of polypropylene ultrafine fibers randomly distributed and dipped together. The appearance is white, smooth and soft. The material fiber fineness is 0.5-1.0μm. The random distribution of fibers provides more space between the fibers. Thermal bonding opportunities, so that the melt blown gas filter material has a larger specific surface area, 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 fabric, also called non-woven fabric, is composed of oriented 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 is composed of the innermost and outermost non-woven fabric layer, the middle electrostatic layer and the meltblown non-woven fabric layer. The medical surgical mask is composed of the non-woven fabric layer and the melt-blown fabric layer. Spray non-woven fabric layer. In addition to supporting the mask, the non-woven fabric layer also functions as a part of the screen, and particles with a large particle size will be blocked by them.
Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low price, and recyclable. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing.
Features of non-woven fabrics
Non-woven fabric has no warp and weft threads, it is very convenient to cut and sew, and it is light in weight and easy to shape, which is very popular among craft lovers. Because it is a kind of fabric that does not need to be spun and weaves, it just oriented or randomly arrange the textile short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods.
It is not interwoven and knitted together one by one yarn, but the fiber is directly bonded together by physical methods, so when you get the sticky scale in your clothes, You will find that it is impossible to draw out the thread ends. Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production rate, high output, low cost, wide use, and multiple sources of raw materials.
The relationship between non-woven fabrics and spunbond fabrics
Spunbond fabric and non-woven fabric are subordinate. There are many production processes for the manufacture of non-woven fabrics, among which spunbond is one of the non-woven production processes (including spunbond, meltblown, hot-rolled, and spunlace. Most of them are currently on the market. Non-woven fabric produced by spunbond method).
According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different components will have completely different styles of non-woven fabrics. The spunbond fabric usually refers to polyester spunbond and polypropylene spunbond; the styles of these two fabrics are very similar and can be distinguished by high temperature testing.

The advantages of graphene non-woven fabrics
1. Antibacterial and antibacterial function
The unique two-dimensional structure of mineral graphene allows it to have a strong dispersive interaction with the phospholipid molecules on the bacterial cell membrane. When the graphene contacts the bacterial cell membrane, it can induce the phospholipid molecules on the cell membrane to escape from the cell and climb Climbing on the surface of the biomass graphene, so as to realize the large-scale direct extraction of phospholipid molecules on the cell membrane by graphene, thereby destroying the cell membrane of the bacteria and killing the bacteria through physical action.
2. Far infrared function
Graphene far-infrared function, at a low temperature of 20-35 degrees, the absorption rate of far-red light of 6-14 microns wavelength is more than 88%, which helps to accelerate the skin surface temperature, expand capillaries, and improve the body Of microcirculation. Can be used for medical protective gear-protective clothing, surgical gowns, masks, hats, etc.
