The main difference between meltblown fabric and non-woven fabric

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) Follow-up cloth: lining, fusible interlining, wadding, shaped cotton, various synthetic leather base cloth, 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.


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 fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of directional or random fibers. It is called cloth because of its appearance and certain properties.


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.


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 netting, and then undergo hydroentangling, needle punching, or hot rolling reinforcement, and finally Non-woven fabric formed after finishing. A new type of fiber product with soft, breathable and flat structure. The advantage is that it does not produce fiber debris, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it also has a cotton feel. Compared with cotton fabrics, non-woven The cloth bag is easy to form and inexpensive to manufacture.


Advantages:


1. Lightweight: Polypropylene resin is used as the main raw material for production. The specific gravity is only 0.9, which is only three-fifths of cotton. It is fluffy and feels good.


2. Soft: It is composed of fine fibers (2-3D) and is formed by light-point hot-melt bonding. The finished product is moderately soft and comfortable.


3. Water-repellent and breathable: Polypropylene slices do not absorb water, have zero moisture content, and have good water-repellent properties. They are made of 100% fiber and are porous and air-permeable. It is easy to keep the cloth dry and easy to wash.


4. Non-toxic, non-irritating: The product is produced with FDA food-grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, non-odor, and does not irritate the skin.


5. Antibacterial and anti-chemical agents: Polypropylene
