National Nonwovens and SABIC collaborate on FR aircraft seat cover

Wednesday, November 21st, 2012

By David Stevenson  Thu Nov 8 2012, 10:39 AM
National Nonwovens, a US manufacturer of nonwoven materials, has developed the first fire blocker for all aircraft seating dress covers in collaboration with SABIC’s (Saudi Basic Industries Corporation) Innovative Plastics.
Marketed and sold under the Ultra-Protechtor fire blocker brand, National Nonwovens was able to create this revolutionary technology by upgrading from aramid to high-performance fibre made from SABIC’s flame-retardant ULTEM resin, a polyetherimide (PEI) material.
Anthony Centofanti, CEO and president of National Nonwovens, said: “The SABIC team provided support to enable us to develop our new Ultra-Protechtor fire blocker.
“This, combined with the outstanding performance of ULTEM fibre, allowed National Nonwovens to easily upgrade from aramid to create a truly high-end product that meets growing industry safety demands and provides aircraft manufacturers with an exceptional fire blocker technology.”
ULTEM fibre is based on the SABIC’s world-leading ULTEM resin, which delivers high heat resistance together with high flow, high ductility and strength to meet tough environmental conditions. (more…)

Quality Fabric Of The Month

Featherweight Filtration

Janet Bealer Rodie, Managing Editor

Channeled fibers, with their increased capillarity, offer interesting possibilities for enhancing a textile’s performance. Morrisville, N.C.-based Allasso Industries Inc.’s Winged Fiber™, developed in collaboration with North Carolina State University’s (NCSU’s) Nonwovens Cooperative Research Center, is exhibiting remarkable filtration and cosmetic delivery performance; and has potential applications in tissue scaffolds, hemostatic bandages, battery separators, insulation and apparel. The bicomponent fiber comprises a shaped core polymer and a sacrificial polymer that are coextruded through a specially designed spinpack. The core features from eight to 32 deep channels between uniform, straight-edged wings. The sheath polymer fills the channels during fiber formation and is dissolved during finishing of the final product.

The Genesis of Sustainable Fibres

Tuesday, September 18th, 2012

25 years ago Courtaulds UK were about to start up the world’s first solvent-spun cellulose process to supply  25 tonnes/week  of  a new rayon fibre  with impeccable environmental credentials .  Process development had started in Courtaulds Coventry Research laboratories in 1979 under the direction of Patrick White[i]  and had remained secret under the “Genesis” codename until 1986.  In June that year the Courtaulds Fibres Viscose Division and Courtaulds Research joined forces to reveal, without spelling it out as such,  a long-range strategy to replace the chemically complex viscose route with a simple, pollution-free, physical cellulose dissolution route.  Here  cellulose in the form of wood-pulp would simply be dissolved without change and reprecipitated as a “lyocell” fibre.  Stratford-on-Avon was the chosen venue for the press conference and because nonwovens were then looking to be the best launch market, several nonwoven reporters[ii]  were present who duly wrote articles on the new fibre[iii].

At that press conference the process outline, the fibre properties,
and the high wet and dry latex and thermal-bonded nonwoven strengths obtained in pilot studies on the new fibres, were revealed. This was followed up in a paper given at Index 87 in Geneva in April[iv].  However work being carried out in Research on its performance in the then embryonic hydroentanglement bonding system and in papermaking was not revealed.  In fact what became the defining feature of the new fibre – its tendency to fibrillate into micro- and nano-fibres when abraded in the wet state – was not mentioned .  Fibrillation was seen as the problem which was making the dyeing, finishing and laundering of conventional textiles complicated.

Coated nonwovens with high conductivity

Tuesday, July 10th, 2012

A commercial method of nickel chemical vapor deposition (CVD) on nonwoven fibers may revolutionize products made for electromagnetic shielding, lightning strike protection, energy storage and a host of other applications that depend on conductivity. Conductive Composites, Heber City, Utah, introduced the CVD-coated nonwovens, which are lighter, thinner and more conductive than nonwovens that are made with conductive fibers. Performance characteristics match or exceed sheets of carbon nanomaterials at a lower price and in an easier-to-use continuous roll format. Every external surface of the fiber is coated and protected, the nonwoven can be wet-processed, and nickel provides corrosion-resistance and magnetic properties.


Sani Professional® Wins Innovation Award at World of Wipes Conference

Monday, June 11th, 2012

WOWOrangeburg, NY, June 7, 2012 – Sani Professional® was awarded the top honor at the 2012 World of Wipes (WOW) International Conference for its new Table Turners®No-Rinse Sanitizing Wipes. The WOW International Conference, held June 5-7 in Chicago, IL, is sponsored by the INDA, a trade association representing the nonwoven fabrics industry since 1968. The WOW Innovation Award recognizes the most innovative advances within the nonwoven wipes marketplace.

New oral hygiene applications for nonwovens

Tuesday, May 22nd, 2012

By  Tara Hounslea

IntelliDent, a division of E4 Technologies, has launched an antimicrobial toothbrush shield in pharmacies throughout the US. The disposable, breathable and fast drying Toothbrush Shield was designed to replace the plastic snap-on caps which the company says have been found to trap and breed bacteria.
Made from antimicrobial SMS nonwoven material that wicks away moisture from the toothbrush, the shield was found to provide a 99.9% effective barrier from bacterial and viral transfer of both airborne and surface microbial contact by laboratory tests. It is slit and ultrasonically welded to form a pocket for a toothbrush.
“Being a person on the go, I carry my toothbrush everywhere. I knew a plastic cap wouldn’t protect my toothbrush, but couldn’t find an alternative. I also knew I couldn’t be the only one facing this issue,” said Susan Klinsport, CEO of IntelliDent. “Inspired to find a solution, I invented the Toothbrush Shield. Now it’s easy to protect your toothbrush – traveling, at work, at home and everywhere in between.”
Ms Klinsport founded the company in 2010 to bring to market oral care products designed to make simple routines healthier.  The US-based Centers for Disease Control (CDC) strongly advises against storing toothbrushes in closed plastic containers, as the humid conditions are more conducive to bacterial growth.
The product was named as one of the five finalists of INDA’s Visionary award in January this year.
