Freudenberg: nonwovens crimping material offers comfort at reduced costs
The producer of technical textiles Freudenberg Performance Materials Holding SE & Co. KG, Weinheim/Germany, is responding to the increased demands of the footwear market with an innovative crimping material made of nonwovens. The new fabric will be presented at the Lineapelle leather goods trade fair in Milan/Italy from February 19-21, 2020.
Freudenberg’s crimping material shows high irreversible deformability and dimensional stability with flexibility and soft material character. In contrast to knitted linings, the multi-directional stretching properties of the material allow uniform longitudinal and transverse stretching over the entire vamp area. A low weight-to-area ratio of the crimping material also leads to further weight reduction of the shoe.
For end users, the wearing comfort is increased, while producers reduce their costs in the production process. This is because the possibility of a direction-independent cutting leads to as much as 10% lower waste. Faster thermoplastic deformability in turn enables shorter production times. After more than 72 hours, the milled sheet still has a 100% accurate impression. At the same time, the high cut edge strength increases the creative possibilities in shoe design.
Navis Tubetex: 6 meter wide nonwovens machine
The producer of finishing machinery for the textile industry, Navis Tubetex, Lexington, NC/USA, has launched a 6 m wide nonwovens machine serving the automotive marketplace. The line comprises stenter with dryer, accumulation, inline inspection, rewind section and includes a sophisticated integrated controls package.
The 6 m line runs a wide range of nonwoven goods. This makes it suitable for wider production runs while providing waste reduction. Complementary, wide-format machinery especially for nonwovens production is currently being engineered. The launch is expected in the first quarter of 2020.

Water UK: soluble wet wipe awarded Fine to Flush accreditation
The world’s first 100% environmentally friendly soluble wet wipe that dissolves in seconds when immersed in water has been awarded the Fine to Flush accreditation by Water UK, London/UK. Fine to Flush is the new official standard identifying which wet wipes can be flushed down toilets safely. The new wet wipes from McCormack Innovation, Kirkcaldy/UK, are not only flushable, they are also biodegradable for landfill.
Wet wipes are the principal cause of 50-70% of blockages in UK sewers. There are around 300,000 sewer blockages each year, costing the country in excess of £100m annually. The majority of wet wipes contain various synthetic fibers, which makes their disposability problematic and time consuming. Some wet wipes could take as long as 100 years to biodegrade.

Dynamic Modifiers: new coating with high flame retardancy
A new non-halogenated FR compound is being introduced by Dynamic Modifiers LLC, Atlanta, GA/USA, a specialty compounder for custom polyolefin compounds and concentrates. Named PAL VersaChar, it can achieve a high level of flame retardant performance as a coating for nonwovens and technical textiles.
PAL VersaChar has been tested to 1,950°C and is shown to prevent all flaming drips of polymer. Char bodies form on the compound surface, protecting against flame creation and delaying heat transfer. Rapid self-extinguishing burn behavior protects any underlying substrate to which it is adhered.
In addition, the compound is light weight and 100% non-toxic, being free from heavy metals, halogens and VOCs. Other properties include very good cold crack performance, hydrophobicity, printability, high chemical resistance and the ability to be custom tailored for specific needs such as UV or antimicrobial performance as required. It has passed ASTM E84 (Class A) with a 15/10 rating, which includes ‘clean’ smoke generation of only 2.3% of the allowable ASTM smoke limits.
In addition to its use as a coating, the compound can be produced as a flexible film or sheet and molded to shape or over-molded to most materials, including metal for corrosion resistance. As a polymeric compound it can be cast or calendered.
A separate adhesive has also been created which bonds to many surfaces.
Oerlikon Nonwoven: new meltblown and spunbond technology at the Filtxpo 2020
Experts of the Nonwoven business unit of the Manmade Fibers segment of Oerlikon Management AG, Pfäffikon/Switzerland, will be presenting solutions for filtration tasks to an international trade audience at the trade fair for filtration Filtxpo 2020 in Chicago, IL/USA, which takes place on February 26-28, 2020.
Meltblown technology is a method for producing fine, separating filter media made from manmade fibers. It is characterized by its constant melt pressure distribution and consistent dwell time across the entire width of the spinning beam. Furthermore, the novel guidance and distribution of the process air outside the coat-hanger distributor offered by the Oerlikon Nonwoven technology prevents so-called hotspots, which overall ensures homogeneous nonwovens properties and basis weights even in the case of delicate raw materials.
The filter efficiency can be increased by means of so-called electro-charging – where the nonwovens are electrostatically charged. Users can choose from a number of variation possibilities and set the appropriate charging method depending on the filter application, allowing the Oerlikon Nonwoven charging unit to also be used for the manufacture of EPA and HEPA class filter media.
Regarding spunbonds, the company is presenting its segmented spin packs, which guarantee even melt distribution and polymer dwell time. The new forming section ensures improved formation evenness across the entire width, even in the case of high spinning speeds, special polymers and polymer combinations. In addition to this, the newly-designed system also ensures that nonwovens only require minimal edge trimming at the end of the production process. The newly-developed mixed fiber technology enables the combining of various filament cross-sections and polymers, in order to set ideal filtering and pleating performances, for example.
James Heal: advanced imaging system to track wicking
The textile testing equipment manufacturer James H. Heal & Co. Ltd., Halifax/UK, has launched WickView, a state-of-the-art instrument that uses an advanced imaging system to track and record the transfer of moisture through fabric and other materials.
A key feature of WickView is its ability to perform both vertical and horizontal wicking testing. Being able to rotate the instrument allows testing to occur in different orientations. Whether for example that fabric is used in elite sportswear (predominantly vertical), or nonwovens or linens deployed on a hospital bed (predominantly horizontal). This is a huge advantage over current market solutions and offers better insight into performance.
WickView’s water delivery system introduces moisture to specimens in an accurate, controlled way. High definition cameras are positioned on either side of the material specimen to record the movement of the moisture. These cameras give full visibility of the test, and use ultraviolet and infrared light to give a good view of the test process, regardless of specimen color or pattern.
WickView is fully supported with a new version of James Heal’s intuitive TestWise software and shows the wicking process in detail. TestWise can calculate a range of 9 metrics including maximum wetted area, area boundary, y axis of spread and wicking speed. Outcomes can be presented visually or in graph format. Analysis of results is easy. Previous tests can be reloaded in to the software and viewed again.
