The difference between melt-blown fabric and non-woven fabric ?

  Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure and good folding resistance. These ultrafine fibers with unique capillary structure increase the number and specific surface area of fibers per unit area.

  Make the melt-blown cloth have 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 cloths.

  The filter material is a kind of melt-blown polypropylene microfibers with randomly distributed knots stuck together, white appearance, smooth, soft fiber denier of 0.5-1.0 material, fibers with randomly distributed fibers provide more opportunities for heat between Bonding.

  Thereby manufacturing a melt-blown gas filter material with a larger specific surface area and a higher porosity (≥75%). After a very high pressure filtration efficiency, the product has 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, (melt-blown fabric production line) is composed of directional or random fibers. It is called cloth because of its appearance and certain product properties.

  Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easily decomposed, non-toxic and non-irritating, rich in color, inexpensive, recyclable, etc. If polypropylene (pp material) particles are used as raw materials, (melt Fabric spraying production line) through high temperature melting, spinning, spreading, hot pressing and coiling to produce in one continuous step.

Market and development space of melt-blown non-woven fabric ?

  My country is a major producer of spunbond meltblown nonwoven fabrics. The actual output of spunbond meltblown nonwoven fabrics is about 2 million tons per year. Five years ago, the actual output of spunmelted non-woven fabrics across the industry reached 1.91 million tons, an increase of 15.42% over the previous year. Among them, the output of spunbond nonwoven fabric accounted for 98% of the output of the entire spun melt industry, and the output of meltblown nonwoven fabric accounted for only 2.05%.

  The main reason for the unsatisfactory growth of meltblown non-woven fabrics is that the scope of application is relatively narrow and the product types are relatively simple. However, the special properties of melt-blown non-woven fabrics are currently irreplaceable in some applications. my country's melt-blown products are mainly used in such market fields as isolation protection, filtration separation, thermal insulation and sound insulation, oil-absorbing materials, battery separators and so on.

  It is reported that there is a large demand for such melt-blown non-woven fabrics in the automotive field. Compared with traditional recycled textile felt, this melt-blown sound-absorbing material has the characteristics of light weight, low combustion, environmental protection, and good sound absorption effect, and is welcomed by domestic automobile manufacturers. In addition, as a building insulation and sound insulation material, its development space is very large.
