2023-05-26
For something so small, nanotechnology has gained a lot of intrigue in recent years.
The definitions are different, but according to the Responsible Nanotechnology Center, the basic work definition of nanotechnology is \"engineering functional systems at the molecular level \"(CRN).
When applications are often applied to science --
Organic chemistry, molecular biology, physics, etc. -
Its position in the non-woven industry continues to rise. [

National Nanotechnology Initiative (NNI)
An organization that accelerates the discovery, development and application of nanotechnology, places scientific dimensions between about 1 and 100 nm, and points out that this is \"a unique phenomenon that makes new applications possible \".
\"Our industry can take advantage of what can be achieved through this science:\" The biggest benefit of nanotechnology depends on the fact that, that is, the basic structure of customized materials on nano-scale to achieve specific performance, thus greatly prolonging the well
Kit for material science.
With nanotechnology, materials can be effectively manufactured to make stronger, lighter, more durable, more lively, more sieve
For example, or better electrical conductors.
At present, there are more than 800 daily commercial products that rely on nano-materials and processes.
\"Non-woven fabric applications can include nano-additives or surface treatments that help resist folds, staining, and bacterial growth, and provide lightweight ballistic energy deflection in human armor.
In addition, nano-engineering materials can also make excellent household products such as defatations and destains, environmental sensors, alarm systems, air purifiers and filters.
While there is much discussion in the industry about what nanotechnology can do, practical applications are still limited.
But that can\'t be said in terms of research.
Several universities and companies are making significant investments and significant progress, and are excited to find out where the technology might go.
Roger Lipton, senior vice president of sales and marketing at McAllen fiber technology, Texas, and Hurricane solved the current state of the market, describing the confusing nature of the market.
He said, \"the nano fiber market has attracted the interest of the world\'s leading companies in markets such as health and filtration, medical devices, transportation, energy and defense.
The mystery surrounding nanofibers is the question: \"Why are these multinationals focused on such a small market?
\"According to BCC research, the market for serving nanofibers in 2010 was only about $0. 14 billion, but it is expected to grow to $2 billion in 20 years.
Tipton said fififirio\'s management team believes this interest is driven by potential-
Greatly enhance the potential of various material functions to provide a competitive advantage for those who are bold enough to be able to use the nano-fiber solution.
\"The answer is simple,\" Lipton said. \"The nanofiber production technology has not kept up with the demand and application . \"
So why is the market so small?
This is partly because of these incredible Super, Lipton said.
High surface area structure is downgraded to niche products with high price due to small volume
Cost production technology.
He said: \"Most applications do not benefit from the various physical properties of the nano-fibers, such as extreme strength that is ideal in filtration media, water-repellent, hydrophilic, softness, low pore rate and
FibeRio\'s vision statement directly responds to this demand: \"changing the material market through the unlimited supply of nanofibers.
To achieve this vision, FibeRio has developed its mandatory technology, both of which \"extend the range of materials that can be processed into nanofibers,\" Lipton said, \"compared to other technologies, while reducing operating costs, productivity has also increased by an order of magnitude. \".
Force scanning is the mechanical processing of polymerization and ceramic materials into nano-scale based on centrifugal force.
By using only centrifugal force, the force is equally effective in solution or pure molten material.
It uses less solvent or has no solvent at all, so it is more cost-effective than electrostatic spinning.
In addition, it does not use any externally heated air-jet device, which is cheaper than the fusion spray.
Industrial scale systems can be installed independently or-
Continuous process system of production line.
Recently, fierio launched the cyclone FE 1.
1. host the filter 2011 International Conference and position organized by INDA in Chicago.
The new cyclone is capable of producing fibers with an average diameter of 500 nm and below, and the standard distribution is very tight, ensuring uniform sliding flow, barrier absorption, in other properties and functions, there is a proprietary design to deposit the nanofibers evenly on its 1. 1-meter width.
The raw materials are delivered to the machine through an advanced extrusion and dissolution pump system, which can be controlled separately or through software
Designed for interface with the customer\'s factory floor controller.
\"Over the past year, we have made outstanding contributions to our technology and equipment, and as the world\'s largest non-woven and filtration companies have asked us to provide them with equipment, expand the market for nano-fiber functional media with new materials and reduced costs, \"added Ellery Buchanan, CEO of fierio
\"Cyclone FE 1.
1 with unparalleled output capability, eliminating the need for toxic solvents makes it a perfect manufacturing platform across multiple business units.
Now, non-woven and filtration companies can quickly build a safe and competitive position.
This is a very exciting moment for the entire fiber and non-woven industry.
\"Grab the NanoWave Hollingsworth & Vose of madong Walpole, is another company that has made great progress not only in R & D but also in the development of commercial applications.
Mayman, director of business development at H & V, discussed the growth of nanotechnology and its penetration in the industry.
Shesays, \"a lot of players have started to provide the nano-fiber material --
Volume producers, fee producers, equipment suppliers and fiber suppliers, and participants from all parts of the supply chain.
However, Mayman pointed out that since there is no common platform, the development of non-textile products is carried out simultaneously with the development of processes.
The size is important, Meiman added.
\"While smaller is not always better for all applications, due to higher requirements for higher efficiency and lower energy use, the trend in some fragments is smaller fiber, overall surface area
\"H & V has established a position in the technology of nano-fibers --
From glass to synthetic to composite.
Mayman explained: \"fiberglass media for HEPA and ULPA applications have been using nanofibers for decades.
\"This medium combines surface and depth filtering properties.
This fiberglass medium has a very high specific surface, which is the main advantage of clean room application and IAQ improvement.
H & V has numerous nanotechnology
Based on products available commercially.
For example, the company provides Nanoweb for air and liquid filtration, an advanced nano-fiber technology for H & V, providing the high performance of sub-micron efficiency, low pressure drop and anti-soot.
It can be used as a separate network or on almost any substrate.
NanoWave for commercial HVAC systems is another product.
\"NanoWave is a synthetic alternative to glass mat media that can improve sustainability and emission efficiency.
With one-
The rigid design of polymer, medium will improve the processing performance and may-mansays.
\"Small pressure drop, large dust-
The capacity of the media is very large, suitable for various HVAC applications.
In addition, charged NanoWave is provided, which provides more submicroscopic particle retention, as well as higher MERV classification.
Working in the field of nanotechnology
Because it\'s new.
A series of unique challenges are presented, as the impact it may have on people has not yet been determined.
\"Removal of Nano
\"Particles are considered a challenge for the future because their impact on humans is not understood,\" Mayman explained . \".
\"Protecting human beings from nano-pollution
Particles are being studied.
However, there are strong signs of high performance micro-glass media on nano-particles.
\"Many end users on the market believe that adding ananofiber layers to existing materials will provide a significant advantage.
An optimized combination of the nano-fiber material and the base can provide an advantage because there are many factors to consider, including compatibility of the material, adhesion of onelayerr to another material, and the nano-fiberH&V iswell-
Provides optimized material composites.
\"R & D companies like FibeRio and Hollingworth & Vose have made some significant progress.
But universities are leading the charge.
The latest research in the laboratory of non-woven and advanced materials of Texas Institute of Technology (TTU)
Committed to the development of cotton nano-fiber composites with enhanced filtration capabilities.
SeshadriRamkumar and Vinitkumar Singh of TTU \"non-woven and advanced materials laboratory\" said recent results show that compared with untreated cotton, the nano-fiber embedded cotton
\"Of course, the durability of this nano-fiber layer is still a problem, because what keeps these layers on the substrate is a weak van der Wall force.
To overcome this problem, it is convenient to use one or more layers of nano-fiber as a sandwich between substrates.
Donaldson has developed this filter product and it is common practice in the industry to use nanofibers in sandwich structures, \"said Ramkumar.
Ramkumar also noted the work being done by Xun Wang, professor and director of the Center for Materials and fiber innovation at the University of Deakin, Australia.
Wanghas has been working to develop new materials using nanotechnology, he said.
According to Professor Wang, his team invented a new form of solvent spinning and got a patent --
In this patented technology, metal discs are used to produce electronics
Spun into nano-fibers instead of syringes.
\"Uniform fiber distribution, higher production capacity, simple operating procedures and simplified machinery make this technology more advantageous than other solvent-based electro-spinning technologies,\" said Ramkumar . \".
Therefore, nanotechnology is being studied in academia.
R & D is designed to help develop the challenges of the product.
But Ramkumar stressed that another important challenge for the nano industry is to thoroughly understand the environmental and health risks associated with nanotechnology --based products.
Some people say that some people are afraid of something they don\'t understand, and that emotion can be applied to nanotechnology.
Last month, the European Commission announced the definition of nano-materials, a move that will help regulators determine suchFine particles
Risk is still largely unknown.
Exist in certain consumer goods.
An EU official said the definition would allow EU regulators to draft a list of products containing nano-materials for risk assessment, although the product will remain on the market when an analysis is conducted.
The Commission\'s definition of nano-materials includes particles between 1 and 100 nanometers in diameter.
A particle about every 100 nanometers wide can be placed on the head of a pin.
Janez Potonik, European environment commissioner, said: \"I am pleased to say that the EU was the first to come forward --
Cutting designation for nano-materials for all regulatory agencies.
We put forward a solid definition based on scientific input and extensive consultation.
In this important economic sector, industry needs a clear and consistent regulatory framework and consumers should be provided with accurate information about these substances.
However, this is an important step towards addressing any risks that the environment and human health may face, while ensuring that this new technology can meet the requirements of the European consumer organization BEUC, with objections to the definition of mission, it is said that products containing nano-materials should prove safe before they are allowed to enter the electronic market.
\"There is a big gap in knowledge, but people are currently exposed to nano products,\" said addsMoniqueGoyens, director general of BEUC . \".
Peter Gehr pointed out that the behavior of nanoparticles is different from that of large particles, which can be easily inhaled through the lungs and entered into blood and blood cells, professor of the Institute of Anatomy at the University of burdock, opportunity and risk guidance team leader for nano materials.
\"Nanoparticles have been found in human organs such as the brain, nose, lungs, skin and intestines, but once they enter these organs, their impact is not clear,\" Gehr said . \".
Some experts say manufacturers may be reluctant to use GM foods in their products because of concerns about similar consumer backlash.
Goyens believes that companies in the past have said that later scientific research has proved that their products are safe, citing examples such as asbestos. \"They (industry)
\"I want to maximize my profits,\" she said . \"
Some environmental activists complain that the organization\'s definition is too narrow, so many products avoid the risk assessment of the EU.
European Environment Agency (EEB)
The EEA said in a statement: \"deep disappointment at the narrow definition of the Commission\'s decision to use the term\" nano-materials \"indicates that industry lobbying has won the commission\'s own scientific advisers.
