Nanofiber equipment. Textile and clothing industry; It is a traditional and very important economic sector that provides jobs for many people (more than 2 million people) in Europe. European Union countries, quota abolition proposals from developed countries such as the United States, Canada and Norway, and increasing competition in Asia have forced the industry to restructure and modernize. Traditional clothing products are no longer enough in EU countries, so EU textile industries are starting to produce innovative and more distinctive features. The most competitive sectors are information technology, biotechnology and nanotechnology.
Nanotechnology is defined as “the precise use of atoms or molecules to create very small structures”. For fibers in general, “nano” provides information about the diameter size of the fiber. However, when a fiber is referred to as nano, different industries use different but very important terms. Some fibers less than one micron in diameter are referred to as nanofibers, while others define nanofibers as fibers with a diameter of 0.3 microns or less.
Electrospinning equipment nanofibers
Although many markets for polymer nanofibers have been studied, it is still too early and very difficult to predict consumption levels and sales volumes. In general, many applications show that there is still a long way to go before the fibers in question are nanofibers.
The production of nanofibers can be done in different ways:
How to equip nanofiber spingenix
Another very interesting method to produce nanofibers is the fibrillation of linear cell fibers like cellulose into smaller nanometer-sized fibers. Spingenix Industries presented the results of several studies on this topic, including processes that convert easily fibrillated lyocell fibers into nanofiber networks. Although the fibers produced by this technique have moderate strength properties, their size and shape vary considerably.

Because the production conditions for lyocell fibers are so critical, this technique is unlikely to be successful and is expected to be at odds with the production conditions required to produce good lyocell fibers that do not fibrillate in other applications.
Nanofiber equipment market
Today, the meltblown technique is the most common production technique used to produce large quantities of small diameter fibers. However, the diameter of the fibers produced by this process is generally 2 microns or more. In addition, although the strength of the fibers produced by this method is low, the diameter of the fibers varies greatly along the length of the fiber and between fibers during manufacture.
Production of fibers by fusion method, which is suitable for the production of fibers in large quantities, many research and development studies have been carried out to modify this method to enable the production of nanofibers by direct fusion production technique. Most of these studies are “confidential” studies known only to the researchers and as such the details have not yet been fully disclosed. Most likely, Nano Technics Korea’s nanofiber filter material is made by modified smelting process instead of electric production.

Aberdeen Nanofiber Technology is another company working to develop a modified meltblown process. Based on this company’s project, nanofibers are formed by a melt-blowing process using a modular die. The fibers produced are a blend of micron and finer fibers. This method is an inexpensive manufacturing method that allows the use of thermoplastic polymers. This technique appears to have the potential to produce large quantities of polymer-based nanofibers at a cost of less than $10 per kilogram. Although not defined as a meltblowing process, it was developed under license by Neumag (Germany) to split the molten polymer stream into small strands by impinging the air jet.
Hills Corporation took a different approach to melt blown by using thin spreader plate technology. With the new dies they used, the number of holes per inch increased to over 100 while the polymer performance per hole decreased. However, the overall output per unit length of the nozzle assembly is the same as in standard meltblowing. With this nozzle technology, the L/D ratio of the nozzle holes is increased to over 10 while the resulting pressure drop is increased from the standard 40 psi to several hundred psi and more.
As a result, the average size of the fused fibers as well as the range of fiber size changes were significantly reduced. Since the nozzle hole diameter varies from 0.1 to 0.15 mm in this process, the polymer must have an MFI of 1000 or more and also be very clean. At this level, the long-term production process is still under development.
The fourth method of making nanofibers is to use bicomponent fibers that can be separated or dissolved. Many approaches have been proposed to use this technology in the fabrication of nanofibers. The most studied approach is the production of sea island type bicomponent fibers using the standard production spinning process.
