Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. With many voids, fluffy structure and good fold resistance, these ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, thus making the melt-blown cloth with good filtering, shielding, heat insulation and oil absorption . It can be used in the fields of air, liquid filtration materials, insulation materials, absorption materials, mask materials, thermal insulation materials, oil-absorbing materials and wipers.

Application range
(1) Medical and sanitary cloths: surgical gowns, protective clothing, sterilization wraps, masks, diapers, sanitary napkins, etc .;
(2) Fabrics for home decoration: wall coverings, tablecloths, bed sheets, bed covers, etc .;
(3) Cloth for clothing: lining, adhesive lining, flakes, shaped cotton, various synthetic leather base fabrics, etc .;
(4) Industrial fabrics: filter materials, insulation materials, cement bags, geotextiles, covering fabrics, etc .;
(5) Agricultural cloth: crop protection cloth, nursery cloth, irrigation cloth, thermal insulation curtain, etc .;
(6) Others: space cotton, thermal insulation and sound insulation materials, linoleum, cigarette filter, tea bags, etc.
The melt-blown filter material is composed of polypropylene microfibers randomly distributed and bound together. The appearance is white, smooth and soft. The fiber fineness of the material is 0.5-1.0 μm. The random distribution of fibers provides more thermal bonding between fibers Chance, so that the melt-blown gas filter material has a larger specific surface area and higher porosity (≥75%). After high-pressure electret filtering efficiency, the product has the characteristics of low resistance, high efficiency and high dust capacity.
Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of directional or random fibers. Because of its appearance and certain properties, it is called cloth.
Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, inexpensive, and reusable. For example, the polypropylene (PP material) pellets are mostly used as raw materials, which are produced by continuous one-step method of high temperature melting, spinning, laying, hot pressing and coiling.

Non-woven fabric characteristics
Non-woven fabrics do not have warp and weft threads. They are very convenient for cutting and sewing, and they are lightweight and easy to set. Because it is a fabric that does not require spinning and weaving, it is simply oriented or randomly arranged 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 braided by individual yarns, but the fibers are directly bonded together by physical methods, so when you get the sticky lining in your clothes, you will find that It's impossible to pull out any thread. Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production rate, high output, low cost, wide use, and many sources of raw materials.
03
The relationship between non-woven fabric and spun-bonded fabric
Spunbond and non-woven fabrics have a subordinate relationship. There are many production processes for the manufacture of non-woven fabrics, of which the spun-bond method is one of the non-woven fabric production processes (including spun-bond method, melt-blown method, hot rolling method, spunlace method, most of which are currently on the market Non-woven fabric produced by spunbond method).
According to the composition of non-woven fabric, there are polyester, polypropylene, nylon, spandex, acrylic, etc .; different compositions will have completely different non-woven fabric styles. Spunbond fabrics usually refer to polyester spunbond and polypropylene spunbond; the styles of these two fabrics are very close, and can only be distinguished by high temperature testing.
Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or mechanical, and then is reinforced by hydroentanglement, needle punching, or hot rolling, and finally after finishing The formed non-woven cloth.
The new fiber products with soft, breathable and flat structure have the advantage that they do not produce fiber debris, they are strong, durable, silky and soft, and they are also a kind of reinforcing material. They also have a cotton feel. Compared with cotton fabrics, non-woven Cloth bags are easy to form and cheap to manufacture.

Advantages of non-woven fabrics
1. Lightweight: Polypropylene resin is the main raw material for production, with a specific gravity of only 0.9 and only three-fifths of cotton. It is fluffy and feels good.
2. Softness: Composed of fine fibers (2-3D), light spot-like hot-melt bonding. The finished product is moderately soft and comfortable.
3. Water repellent and breathable: polypropylene chips are non-absorbent and have zero moisture content. The finished product has good water repellent. It is composed of 100% fiber with porosity and good permeability.
4. Non-toxic and non-irritating: The product is produced with FDA food-grade raw materials, does not contain other chemical ingredients, has stable performance, non-toxic, no odor, and does not irritate the skin.
5. Antibacterial and anti-chemical agents: polypropylene

Graphene non-woven fabric advantages
1. Antibacterial and antibacterial function
The unique two-dimensional structure of the mineral graphene allows it to interact strongly 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 detach from the cell and climb up. The surface of the material graphene, thereby realizing the large-scale direct extraction of the phospholipid molecules on the cell membrane by the graphene, thereby destroying the cell membrane of the bacteria, and killing the bacteria through physical action.
2. Far infrared function
Graphene far-infrared function, which can absorb more than 88% of far-red light with a wavelength of 6-14 microns at a low temperature of 20-35 degrees .
Can be used in medical protective equipment-protective clothing, surgical clothing, masks, hats, etc.
