During the epidemic, there are many people start to understand the mask, whether the production material of the mask is a moltenbound caused many people’s discussion, then what is the difference between the melting bumps and non-woven fabrics? Why choose meltblowing? Come understand!
The melting cloth mainly raw material with polypropylene, and the fiber diameter can reach 1 to 5 microns. There are many gaps, the structure is fluffy, and the pleat resistance is good. These ultrafine fibers with unique capillary buildings increase the number and surface area of the unit area fibers, thereby making the meltblown cloth having good filtration, shielding, insulation and oil absorption. . It can be used in air, liquid filtration materials, isolation materials, absorbing materials, mask materials, thermal materials, oil absorbing materials and wipes.
The meltblown filter material is bonded together by the random distribution of polypropylene ultrafine fibers, is white, flat, soft, material fiber fineness is 0.5-1.0 μm, and the random distribution of fibers provides more thermal bonding between fibers. Opportunity, thus makes the meltblower filtration material have a greater specific surface area, a higher porosity (≥75%). After high pressure eradic filtration efficiency, the product has the characteristics of low-resistance, efficient, high-volume dust.
Non-woven fabric has moisture-proof, breathable, flexible, light, non-combustion, easy to decompose, non-toxic and non-irritating, rich in color, low price, recycling and other features. If polypropylene (PP material) pellet is raw material, it is produced by high temperature melting, spinning, spreading, and hot pressing.
It is not interleaved by a yarn, which is bonded together, but the fiber is bonded directly through the physics method, so when you get the stick in your clothes, you will find that It is a wire that can’t draw a root. The nonwoven fabric breaks through the traditional textile principle and has a short process flow, fast production rate, high production, low cost, and many raw materials.
