From the Sector

A new non-halogenated FR compound called PAL...VersaCHARTM can achieve a new level of flame retardant performance as a coating for nonwovens and technical textiles.

PAL...VersaCHARTM has been tested to 1,950°C – the highest to date – and 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 behaviour protects any underlying substrate to which it is adhered.

The compound 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, the compound is light weight, at a specific gravity of 1.0, and 100% non-toxic in every respect, being free from heavy metals, halogens and VOCs. 

Other properties include excellent cold crack performance, hydrophobicity, printability, extreme chemical resistance and the ability to be custom tailored for specific needs such as UV or antimicrobial performance, as volume warrants. The compound is also very competitively priced.

In addition to its use as a coating, PAL...VersaCHARTM compound can be produced as a flexible film or sheet and moulded to shape or over-moulded to most materials, including metal for corrosion resistance. As a polymeric compound it can be cast or calendered and typical durometers from 80-99A for flexible-to-high rigid formats are practical. 

Separately, an adhesive has been created which bonds to many surfaces. In internal evaluations of two laminated plies of woven carbon fibre and two plies of glass fabrics, both passed a 60 second vertical burn with no ply separation, distortion or flaming drips from the adhesive.

Dynamic Modifiers envisages many uses for PAL...VersaCHARTM, from aerospace to the protection of rigid structural materials in building interiors etc.   
 

The Oerlikon Manmade Fibers segment will be presenting itself at the Egy Stitch & Tex 2020 between March 5 and 8, 2020 in Cairo – with a clear focus on the needs of the African market. In Hall 1, Stand B2 The Oerlikon Barmag and Oerlikon Neumag experts will also be showcasing the comprehensive product and service portfolio of the world market leader for manmade fiber systems at the stand of Oerlikon’s representative ATAG Export & Import.

The spotlight of the Oerlikon Manmade Fibers segment’s trade fair attendance will be on two core technologies: the new generation of Oerlikon Barmag eAFK Evo texturing machines is to be unveiled within the African market for the very first time. It promises higher speeds and productivity with consistently high product quality, along with lower energy consumption and simpler operation vis-à-vis comparable market solutions. In particular, the numerous value-added features include two that convince with cutting-edge technology: the optimized, innovative EvoHeater and the EvoCooler, a completely newly-developed active cooling unit.

The second technology focus offers new opportunities for the Egyptian market and the Middle Eastern markets in particular: with Oerlikon Neumag’s BCF S8 monocolor and tricolor system, the segment will be unveiling its new carpet yarn production flagship. Superlative spinning speeds, up to 700 individual filaments, finer titers of up to 2.5 dpf – the performance data and technological finesse of the new system have already made a huge impression at numerous trade fairs and roadshows over the past year. The tricolor’s core component is the new, patent-pending Color Pop Compacting unit (CPC-T) for even more flexible and more even color separation. With the CPC-T, individually-controllable air pressures for each color provide pre-tangling, which accentuates the colors and hence makes more than 200,000 different shades possible. Whereas it has been very difficult to manufacture strongly color-separated or color-accentuated BCF yarns from polyamide 6 to date, this will in future be possible thanks to the CPC-T system. As a result of the new design, the CPC-T is now also suitable for processes with low yarn tensions.
 
Expanded product offering for manufacturing carpet yarns
Know-how covering all relevant technologies deployed in manmade fiber spinning plants enables Oerlikon – as the world’s only manufacturer – to expand its range of products and services for making carpet yarns. The POY- and texturing-based system concept is designed for a carpet and home textiles segment that demands particularly soft and bulky polyester yarns with BCF-like properties. Here, the aim is to produce yarns with titers of max. 1300dtex and typically more than 1,000 filaments, with typical products including, for example, 1300dtex f1152, 660dtex f1152 and 990dtex f768. The machine concept comprises the well-known WINGS HD POY winder, along with the eAFK Big-V texturing machine.

Kelheim’s premium tampon fibre Galaxy® has proven effective in sanitary pads: It can substitute up to 70% of the synthetics in ADL (Acquisition-Distribution-Layers) in feminine hygiene pads. The amount of feminine hygiene waste is enormous – and often the time it takes for these products to degrade is hundreds of years longer than the lifespan of the woman who used it, because the synthetic components are not bio-degradable. Changing consumer behavior drives the need for environmentally friendly yet safe alternatives.

The viscose hygiene fibres from Kelheim offer significant ecologic advantages: they are made from cellulose, which means they are based on renewable wood and they are fully biodegradable. These fibres are manufactured exclusively in Germany, in one of the most environmentally friendly plants worldwide.

Galaxy® in sanitary pads offers not only a benefit for the environment. Due to its excellent wicking and absorption capacity it conducts liquids quickly and efficiently away from the body and leaves a pleasant feeling on the skin – in other words, it does exactly what the ADL layer is made for. In addition, Galaxy® helps to distribute the liquid evenly in the absorbent core enhancing so the overall performance of the pad.

“Plastic must disappear from these single-use products. The substitution of single synthetic components in sanitary pads is the first step”, says Dominik Mayer from the Bavarian fibre expert’s R&D team. “Down the road we want to offer a completely bio-based solution for sanitary pads and for various other hygiene applications.

Market and technology analysis confirms big potential for tape inserts in the injection molding process. Following the finalization of a major consortial project led by the Aachen Center for Integrative Lightweight Production (AZL) and the Institute for Plastics Processing at RWTH Aachen University (IKV), the result is clear: tape inserts offer enormous potential for injection molding parts. For suitable components, product costs and component properties can be positively influenced.

In cooperation with 20 industrial partners, the two renowned Aachen research institutes AZL and IKV carried out a detailed analysis of tape inserts in injection molded components over a period of eight months. The tapes, which are a few tenths of a millimeter thick, are continuous fibers, typically made of glass or carbon, completely impregnated and embedded in a thermoplastic matrix. The tapes can be precisely aligned to the loads in a component and are used primarily in high-performance applications with the aim of weight reduction. The aim of the conducted analysis was the identification of potential applications and the estimation of a wider range of applications.

The project was divided into several phases: Phase I was used to identify the current status. In 20 interviews with representative companies of the injection molding industry, the researchers gathered why tape inserts have rarely been taken into account so far, when defining the material concepts to be analyzed. The lack of information about the material class, the procedure and tools for the development process and the necessary production technologies were cited as major challenges. This is where the consortium will take action and provide comprehensive information during the “Technology Information Day” on the extensively prepared state of the art and the high degree of maturity of the supply chain. Based on the status quo, they developed a methodology for analyzing the technological and economic potential of tape inserts in injection molding applications.

Both the previous results and the planned follow-up projects are the subject of the “Technology Information Day" at K 2019, to which the companies involved in the study, the AZL and IKV, invite all companies along the value chain, from raw material manufacturers to injection molders to OEMs. (Date: 18th October 2019, 10:00 am to 1:30 pm, Trade Fair Düsseldorf CCD South, Room 002).

The consortium, amongst others consisting of Asahi Kasei Europe GmbH, BASF SE, Borealis AG, BÜFA Thermoplastic Composites GmbH & Co. KG, ENGEL AUSTRIA GmbH, Huesker Synthetic GmbH, LG Hausys R&D Center, Mitsui Chemicals, Nippon Electric Glass, Polyscope Polymers BV, POLYTEC GROUP, Simcon kunststofftechnische Software GmbH, SABIC and Toray International Europe GmbH, is inviting to the “Technology Information Day” at K 2019. The goal is to inform about the technology and to identify topics for future collaboration.
