What is the Difference between Meltblown and Non-Woven Fabrics?

Apr. 06, 2016

Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many gaps, 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 wipes.

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

Thereby manufacturing a melt-blown gas filter material with a larger specific surface area and a higher porosity (≥75%). After very high pressure filtration efficiency, the product has low resistance, high efficiency, high dust holding capacity, etc.

Melt-blown Fabric Felt

Non-woven fabric is composed of directional or random fibers. It is called cloth because of its appearance and certain product properties.

Non-woven fabric is moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, inexpensive, recyclable and so on. For example, using polypropylene (pp material) particles as raw materials Melting, spinning, spreading, hot pressing and coiling are produced in one continuous step.

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 light in weight and easy to shape.

Because if it is a fabric that can be formed without spinning and weaving, only the textile short fibers or filaments are analyzed or oriented or randomly arranged to form a web structure, and then we use traditional machinery, thermal bonding or chemical, etc. The method needs to be reinforced.

It is not interwoven by a yarn, but the fibers are directly joined together by physical methods, so when you get a sticky name on the clothes, you will find that it cannot pull out a thread. Non-woven fabrics break through traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and many raw material sources.
