Applications of Melt Blown Nonwoven Fabrics

Melt blown nonwoven fabrics are soft, have very good wind resistance, excellent air permeability, and are very lightweight because of their extremely small fiber diameter and small pore size.

Products made of melt blown nonwoven fabrics have become popular in the world. The basic composition of thermal insulation materials based on melt blown nonwoven fabrics is about 65% PP melt blown nonwoven fabrics and 35% coarse denier three-dimensional crimped PET fibers. The added coarse denier fiber solves its bulkiness problem.

1. Melt blown nonwoven fabrics are used in filtration

It is said that the thermal insulation performance of this thermal material is 1.5 times that of down, and the structure is also like down. Eco-cotton is actually also composed of melt blown fibers.

It is a material with a special structure of a spacer layer in the middle of two layers of melt blown nonwoven fabrics, so it has more voids, making it better at keeping warm, and is favored by the military logistics department.

It is suitable to use melt blown nonwoven fabrics as the filter material for the separation of liquid-solid mixtures and gas-solid mixtures because the diameter of the fibers on the fabric surface is smaller, the surface area is larger, the pores are smaller, and the porosity is high.

It is suitable for high-efficiency filtration equipment in air filtration, such as masks in labor insurance products, medical masks, gas masks, etc. Melt blown nonwoven fabrics can effectively filter dust, bacteria and other harmful particles in the air, and can also be used as filter materials in air filters of air conditioners, automobiles and engines.

Due to the requirements of environmental protection, in the field of air filtration, melt blown nonwoven fabrics are now widely used as filter material. Due to the gradual enhancement of environmental protection awareness, melt blown nonwoven fabrics will also have a broad market.

2. Melt blown nonwoven fabric as absorbent material

The microporosity and hydrophobicity of polypropylene melt blown nonwoven fabric make it an ideal oil-absorbing materials, and its oil-absorbing capacity can reach dozens of times its own weight.

Melt blown nonwoven fabrics have fast oil absorption speed, good water and oil replacement performance, and do not deform for a long time after oil absorption. Melt blown nonwoven fabrics can be reused and stored for a long time, so they are favored in this field.

Melt blown nonwoven fabrics are widely used in melt blown absorbing materials for the treatment of oil leakage of equipment, marine environmental protection, sewage treatment and other treatment of oil leakage and oil pollution.

At present, there are specific laws and regulations that require ships and ports to be equipped with a certain amount of melt blown nonwoven oil-absorbing materials to prevent timely disposal of oil spills and avoid environmental pollution.

Melt blown nonwoven fabrics are usually used in oil-absorbing pads, oil-absorbing grilles, oil-absorbing belts and other products, and even oil-absorbing products for household use are gradually being promoted.
