Meltblown non-woven fabric(PP Meltblown Nonwoven Supplier) has a very wide range of applications in heat preservation and is a good heat preservation material. Next, let's talk about the application of meltblown non-woven fabrics in heat preservation:

Meltblown nonwovens(Face Mask Fabric Wholesale) have the characteristics of large specific surface area, small voids (pore size ≤20μm), and high porosity (≥75%). For example, the specific surface area of ​​the meltblown nonwoven fiber with an average diameter of 3μm [equivalent to an average fiber linear density of 0.0638dtex (fineness of 0.058 denier)] is 14617cm2/g, and an average diameter of 15.3μm [equivalent to an average fiber line The specific surface area of ​​the spunbonded nonwoven fiber with a density of 1.65 dtex (with a fineness of 1.5)] is only 2883 cm2/g.

Since the thermal conductivity of air is much smaller than that of ordinary fibers, the air in the pores of the melt-blown non-woven fabric makes the thermal conductivity smaller, and the heat loss through the fiber material of the melt-blown non-woven fabric is very small, and there are countless super The static air layer on the surface of the fine fiber prevents heat exchange due to the flow of air, so that it has a good heat insulation and warmth retention effect.

Polypropylene (PP) fiber is a variety of existing fiber materials with a very low thermal conductivity. The specially treated meltblown thermal insulation flake made of PP fiber has a thermal insulation performance of 1.5 times that of down and 15 times that of ordinary thermal cotton. Especially suitable for making ski suits, mountaineering suits, bedding, sleeping bags, thermal underwear, gloves and shoes, etc. Products with a basis weight of 65-200g/m2 have been used to make warm clothing for soldiers in cold regions.

In addition to the application of meltblown non-woven fabrics(Polypropylene Meltblown Factory) in heat preservation, there are also very important applications in filter materials and oil absorption. In the future, we will slowly introduce to you that our company is a non-woven fabric manufacturer that processes and customizes non-woven products for various purposes.
