Mahlo: transparency in process control for technical textiles

High-performance technical textiles have to fulfill their task to 100% in order to prevent damage and danger. The final product has to fully strictly meet requirements and gray areas are unacceptable. The processes have to be transparent, so that the user can recognize discrepancies at any time and can react to them.
A prerequisite for a working product, independent of further treatment, is a straight web.
The automatic weft straightener Orthopac RVMC-15 from the manufacturer of measuring, control and automation systems Mahlo GmbH & Co. KG, Saal a.d. Donau/Germany, detects and straightens 97% of all known webs. For s-shaped distortions and non-detectable fabric, the pin wheel straighteners only work only for non-elastic products, however.
This is different with the Orthomax RFMB-15, a fusion of pin wheel and roller straightener. Thanks to combining both technologies, the system minimizes distortions in web as well as elastic knitting. Many textiles made of elastic raschel knitted fabrics already benefit from these advantages.
The next step is monitoring the further processing. With the help of scanners and sensors, the quality control system Qualiscan QMS-12 makes important parameters visible and therefore controllable. By measuring basis weight before and after the coating, one can determine the weight of the single layers.

Lenzing: award for sustainable nonwovens technology

The Austrian State Prize for Innovation is awarded annually by the Federal Ministry for Digital and Economic Affairs, Vienna/Austria, to the most innovative Austrian company. On October 20, 2020, the producer of cellulosic fibers, Lenzing AG, Lenzing/Austria, was awarded the prize as recognition for its innovative achievements concerning sustainable nonwovens technology.
With the Lenzing web technology the company has developed a patented technology for a promising solution for eco-friendly products that counteracts the pollution of the environment by plastics.
Sustainable and eco-friendly nonwovens are produced from the renewable raw material wood. These are not only plastic-free, they also score points for their environmental friendliness.
The pollution of the environment by plastics is an important problem of our time. Every day, worldwide millions of hygiene products and wipes end up in garbage and sewage. Most of them consist of up to 80% polyester or other fossil, non-biodegradable materials which remain in the environment as pollution.

Oerlikon/Procter & Gamble: exclusive collaboration for high-class wipes

In a global marketplace, collaboration is just as important as competition. This is what motivated Procter & Gamble Corp., Cincinnati, OH/USA, and Oerlikon Nonwoven, Neumünster/Germany – Teknoweb Materials srl., Palazzo Pignano/Italy, to agree on an exclusive license agreement to market and sell the Phantom platform worldwide.
Oerlikon already entered into a strategic partnership with Teknoweb in 2017 aimed at extending the nonwovens production systems portfolio.
The patented process for hybrid nonwovens combines the best of both airlaid and spunmelt technologies to deliver new, flexible ways of creating wet and dry wipes. The Phantom technology offers additional benefits by reducing resources and cost, while increasing overall performance. The exclusive license gives Oerlikon Nonwoven – Teknoweb Materials total access to the patents, know-how, and pilot lines developed by Procter & Gamble. The research and development team at Procter & Gamble continues to support Oerlikon Nonwoven – Teknoweb Materials distribute this technology worldwide. In addition, Oerlikon Nonwoven – Teknoweb Materials have further refined the process into their own Levra technology – an entry-level option which offers tailored production volumes with lower investment costs but is still suitable to be upgraded to the premium Phantom model in the future.
Essentially, Phantom technology was developed to produce hybrid substrates. The spunmelt and airlaid processes are merged into one step to combine cellulose fibers, long fibers such as cotton, or even powders with polymer fibers in unprecedented ways. This technology has clear advantages in terms of resources, performance and cost compared to the previous processes on the market. By removing hydroentanglement, it is no longer necessary to dry the material. Adjusting the process can optimize relevant product characteristics such as softness, strength, dirt absorption, and liquid absorption. In the end, this even increases the quality of the product itself.

ACIMIT: conference confirms industry downturn

The world that awaits us in this post Covid-19 era was the dominant theme discussed at the conference of the Association of Italian Textile Machinery Manufacturers (ACIMIT), Milan/Italy, held in Milan on October 6, 2020.
In 2019, Italy’s production output of textile machinery dropped by 11% compared to 2018, while exports fell 12%. The sharp decline in manufacturing activity in 2019 was common to both foreign and domestic markets in Italy. This widespread lessened demand in the main Asian and European markets has weighed heavily on machinery sales abroad, also affecting the USA and South America. A similar scenario was observed in Italy, where both imports of machinery of foreign origin and deliveries by Italian manufacturers decreased significantly.
This precarious economic situation then suffered from the strong impact brought on by the pandemic. The repercussions are highlighted by a severe scaling back in orders for Italian producers. The order index for the first 6 months of 2020 dropped 39% compared to the same period for January to June 2019; a recessionary picture that remains confirmed for the whole of 2020. A recovery towards export levels resembling those of the period prior to Covid-19 can only be expected in 2021.
The experience of recent months has brought to light the urgency of accelerating the digital transformation of businesses. ACIMIT has continued to support its associates in this development process.
