The Development Status and Application of Meltblown Non Woven Fabric

New coronaviruses are spreading around the world, posing a great threat to human life. Medical masks and protective clothing have become important protective equipment to prevent the spread of virus and protect people's health, and meltblown non woven fabric plays a great role in it.

1.Meltblown non woven fabric meltblown technology development at home and abroad

As an early non-woven fabric production process, the meltblown non woven fabric process was successfully developed by the US Navy in the 1950s. At the end of the 1970s, Exxo transferred this technology to civilian technology. Based on this, major companies conducted research and obtained patents. For example, JMI improved the traditional meltblown molds, speeded up the mold change by parallel mold equipment, and saved the mold change time of the production line; in order to improve the production efficiency, Biax developed the meltblown mold multi-row spinneret hole structure; Japan Chiso developed the two-component conjugate fiber meltblown fabric and island fiber meltblown fabric equipment for the first time; Germany Levenhaus improved the meltblown molds, which made the production High efficiency and rapid development of production performance.

As early as the late 1950s, China began to study meltblown technology. early 1990s, Beijing Institute of Chemical Industry and China Textile University designed meltblown die in China produced nearly 100 units. Then, Anhui Aohong and other enterprises introduced five continuous meltblown production lines, opening up a new situation in the Chinese meltblown market. At that time, the main application areas in China were battery partitions, oil-absorbing materials, filter materials, etc., but the development was slow due to market restrictions. In the past decade, with the development of economic and technological development and environmental awareness, China's meltblown technology is developing rapidly, meltblown production equipment to fully realize the localization.


2.Characteristics of Meltblown non woven fabric

Polypropylene fiber has the advantages of abundant raw materials, high strength, light weight, good chemical resistance, anti-moth, anti-mildew and low pollution. meltblown non woven fabric has irregular fiber arrangement, and the structure makes the specific surface area larger and the pore size smaller. Therefore, it has better filtration and dust capacity than other nonwoven fabrics, and is widely used in the field of filtration materials; its nonwoven fabric contains a large number of micropores and excellent lipophilicity, and is widely used in the field of oil-absorbing materials. In addition, because of its excellent reprocessing performance, its application fields are becoming more and more extensive, such as medical protection, sound insulation materials, thermal insulation materials, battery diaphragm, etc.


3.Applications of Meltblown non woven fabric

1 Medical protection

Medical protection is its main application area. With the increasing demand for health protection, their position in the field of medical and health care is also increasing. In recent years, it is combined with spunbond non woven, which has the characteristics of high strength, good handfeel, high efficiency and low resistance.

2 Warm material

meltblown non woven fabric fiber has large specific surface area, small pore size and high porosity. The fiber structure can store a large amount of air, effectively prevent heat loss, with good warmth and breathability; it is an ideal warm material, light weight, soft to the touch, but not thin.

3 Oil-absorbing material

It has good pro non-polluting new oil-absorbing material with good lipophilicity, poor moisture absorption, insoluble in oil, strong acid and strong alkali and other chemical properties. Light weight, oil absorption can still float on the water surface for a long time without deformation; non-polar material, its oil absorption capacity can reach dozens of times its own weight; non-toxic, good water-oil replacement, can be reused.

4 Filtration material

Filtration material is its earliest application area, and its fiber diameter is less than 5μm, which is very suitable for use as air filtration material. In particular, the meltblown material treated with electric standing electrode has the characteristics of fluffy structure, high porosity, high dust capacity, low breathing resistance and high filtration efficiency.

meltblown non woven fabric

Meltblown non woven fabric has a good market prospect as an important material and needs to be continuously increased in research and development to improve performance and reduce cost.
