Filter-Focus

Filter-Focus, Fall/Winter 2002

Our third edition of Filter-Focus examines emerging challenges and trends facing our filtration customers.  Our focus has shifted from spanning the entire industry and finding  niches related to our capabilities, to concentrating on our customers specific requirements and our abilities to provide them with the best filtration fabrics utilizing our superior needling processes.

Below is Part 3 in National Nonwovens’ continuing Filtration Challenges series,
which discusses solutions to the industry’s difficult challenges.

Filtration Challenge 3: Abrasion Resistant Filtration Materials for High Temperature Environments 

Challenge:  Design a uniform, long-life, abrasion resistant filtration material for high temperature environments.

NOMEX®, manufactured by Dupont Advanced Fiber Systems, is the product of choice in a wide range of high-temperature filtration applications, and is implemented by many nonwoven manufacturers of filter fabrics.  However, National Nonwovens utilization of NOMEX® combined with our innovative technology is unique and superior.

Solution:  National Nonwovens’ PurusFelt^®:  Style TFIL18 made with 100% Nomex for high temperatures when requirements demand thermal stability up to 480º F.  PurusFelt^® features a mechanically interlocked, pure fiber supported  “scrimless” design with many added features:

 

SPECIFICATIONS

Applications:

PurusFelt^® is offered in National Nonwovens’ inventory program so your requirements can be met consistently and efficiently.  National Nonwovens also has a state of the art dye house with the ability to custom dye the fabric to your specifications.

Odor Absorption – Filtration Hot Topic

Controlling offensive odors and chemical fumes is big business with products that range from casual solutions to highly scientific laboratories studies.  Several innovative filter medias have made tremendous strides in absorbing some of the more challenging odors.  National Nonwovens has developed a specialty material specifically for filters that reduce the following odors:

National Nonwovens has developed an innovative filter material, Style: FIL012 - Filter 12, which stops odors by neutralizing harmful vapors.  Filter 12 is a complex nonwoven composite that absorbs and neutralizes complex aldehyde and ketone vapors; potential carcinogens often found in hospitals and laboratories.  National Nonwovens’ patented SureSorb^® fiber is durable and resists tearing, even when saturated.  Furthermore, incineration of filter is clean, efficient, and reduces the threat of exposure.

Filter 12 absorbs many chemical compounds thereby reducing various odors.  The table on the left specifies an array of chemicals and the corresponding absorption capability. 

National Nonwovens also has capability to add particular solutions to Filter 12 that will make the material extremely effective on the removal of common oxide gases including: carbon dioxide, nitrous oxide, sulfur dioxide, hydrogen sulfide, and halogens (chlorine).  We also have the expertise to customize materials for you that will effectively filter other odors, gases, and specific metals.

Current Events: Germicidal Bacteria & viruses

Hundreds of travelers aboard Cruise Ships have become ill in recent months, many from common illnesses and viruses that cause mild to moderate gastrointestinal symptoms.  Although US-registered ships have the highest hygiene standards, consumers and those responsible for the hygiene of ships, restaurants, and other communal recreation facilities are raising many red flags.  The Vessel Sanitation Program (VSP) at the Centers for Disease Control and Prevention (CDC) oversees sanitation practices on all US cruise ships.   The VSP has strict sanitation rules regarding general and specific health conditions aboard cruise ships, and it performs frequent cruise ship inspections, both scheduled and unannounced. 

As the CDC and society demand safer environments, anti-microbial materials and sub-micron filters will be spotlighted as solutions.  National Nonwovens is developing a durable, abrasion resistant filtration media that will be effective against airborne bacteria and viruses.  In addition, we can be your partner in providing effective solutions in both the filtration markets and the hygienic wipe markets with many types of fabrics.

Market Trends and competition are creating a more demanding environment requiring more innovation and technology. The key to engineering new technology is the commitment of material suppliers to generate new ideas that can be transformed into new products providing increased performance over traditional materials. The new emerging needlepunch technology reflects our commitment to the filtration market. At National Nonwovens, we will continue to manage new technology to bridge today’s products and technology to meet the future market demands.

 

Coming up next issue….
In the next Filter-Focus, we will discuss the benefits of PPS fibers (polyphenylene sulfide)
