Introduction to the latest meltblown non-woven technology method in 2017

Melt-blown non-woven fabric is a non-woven fabric made by the melt-blown process (Melt Blown), and it is also a product made directly using the melt-blown spinning process. With the continuous progress of processing technology, the diversification of raw materials and the continuous improvement of their cost performance, its outstanding characteristics in absorption, filtration, heat preservation, and sound insulation have made it more and more popular in the fields of hygiene, medical treatment, construction, industry, and civilian use. More and more extensive applications. Nowadays, the most commonly used meltblown nonwoven technology on the market is classified into one. The meltblown nonwoven technology of Exxon, USA, began to melt in the 1960s. The research on spraying technology and the earliest technology patents are obtained, which is a mature technology. The process is still the mainstream production process widely used in the current meltblown non-woven fabric industry. It is characterized by the use of a single row of spinneret holes and hot air drafting. The drafting hot air blows at a certain angle from both sides of the spinneret. . 2. Biax-Fiber Film's meltblown non-woven fabric production line The technology of Biax Corporation is another process for producing meltblown non-woven fabrics. It is characterized by the use of multiple rows of spinnerets and drafting airflow. The melt is sprayed from two concentric circles that are nested together. Due to the higher density of spray dead holes, there is a higher production volume and the energy consumption of the product is lower. It is a process under development. 3. The high-altitude density meltblown spinneret and two-component meltblown technology of the American Hills company. The meltblown technology patent of the American Hills company uses a denser hole pitch (100 holes/inch ), the minimum hole diameter is 0.125mm, the length of the spinneret is L/Du003d60 (the maximum can reach 100), and it can be used at a pressure of 103bar (approximately equivalent to 1500psi). The pressure difference at the end can be increased from the standard 40psi to several hundred psi. The above is a brief introduction to the three more commonly used meltblown non-woven technology methods on the market.
