From the Sector

KARL MAYER GROUP will be presenting a WEFTTRONIC® II G at the ITMA with new features and upgrades for greater efficiency. This warp knitting machine with weft insertion produces lattice structures from high-strength polyester, which are firmly established in the construction industry in particular. With a working width of 213", it offers productivity and further advantages through design innovations. New features include weft thread tension monitoring, management and the new VARIO WEFT laying system. The component for the weft insertion aims at maximum flexibility. It allows the patterning of the weft yarn to be changed quickly and easily electronically, without mechanical intervention during yarn insertion and without limits on repeat lengths. In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.

The textile industry, one of the major industrial sectors worldwide, is going through a significant revolution, with changes taking place in various sections of textile processing. Biotechnology and biomimicry, for example, are continuously playing an important role in redefining the influence of the textile industry on society, and so is progress made in auxiliary chemistry, with advances investigated and then applied in almost every section of textile processing.  The outcome is amazingly promising.

Modern, real science is inextricably intertwined with environmental consciousness and they are definitely not mutually exclusive.

At RUDOLF GROUP modern, real science means pushing R&D so to constantly explore new technology and innovations that help transform the textile and fashion industries. We work to reduce the overall dependency on traditional and virgin resources.  Getting textile manufacturers as well as brand and retailers on board is key to achieve real change. By 2030 we aim for a significant fraction of our products to be either sourced through paths alternative to the traditional petrochemicals, or by upcycling waste and/or byproducts from other industries.

“This is the kind of genuine, tangible, environmental consciousness that truly defines us and that entails that RUDOLF GROUP has a responsibility for the needs of society as a whole.” Said Alberto De Conti, Head of Rudolf Fashion Division “We have a maniacal attention to the environmental impact of our operations and products. We have truly embedded in ourselves the notion that “sustainability” is a key issue and critical to the long-term survival of our company and of society at large. “

The combination of modern, real science and environmental consciousness leads to what RUDOLF GROUP call aspirational chemistry something unique and something that positions us as shining example and guiding light throughout the industry. That is, in fact, BETTER CHEMISTRY.

Two are the innovations rooted in aspirational chemistry that RUDOLF HUB1922 presents. The first one is our WASHLESS technology and the second one is a brand new launch: LASER SMOOTHER, which supports laser technology and helps creating much better denim looks.

WASHLESS

HUB1922 WASHLESS, which can be applied to both denim and non-denim, is the simultaneous application of
-    proprietary fluorine-free DWR (Durable Water Resistance) based on biomimicry to repel dirt
-    anti-microbial, anti-bacteria and anti-viral, non-migrating chemistry to stop body odour.
The combination of the 2 translates into garments that don’t require to be washed as much.

Life cycle assessment studies on clothes, detergents and washing machines show that home laundering is always the most energy‐demanding period during these products' life cycle, even higher than production or transportation phases.

“WASHLESS aims at changing consumer habits in clothing maintenance to a more environmentally friendly direction and represents a change that is the most feasible and efficient. Making washing machines obsolete is impossible, but even though the technologies in clothes cleaning have improved greatly, the washing frequency has not been reduced. We own more and more clothing and wash it more frequently. This increased amount of washing counteracts the technological improvements in home laundry. “ said De Conti.

It is only by understanding the climate change impact associated with home laundering that product innovations and consumer education can be explored. Studies consistently show that a carbon dioxide reduction of 105 MT and electricity savings of 142 thousand GWh can be obtained by reducing home laundering, on average, by 1/3. This is roughly equivalent to removing 12% of the 140 M passenger cars in the US, or taking 23 coal power plants off the grid. In addition, more than 60% of water consumed while laundering (2,000 billion liters) can be reduced through these strategies.

LASER SMOOTHER

Laser denim is the current dominant technology available to the denim industry to create locally abraded areas, vintage effects, whiskers, patterns, patches, and even intentional holes and tears in a garment. Laser technology uses less water, harmful chemicals (such as potassium permanganate) and energy to create a wide variety of denim looks.

However, laser is not always able to produce the desired look, on the desired fabric, in the desired time. Therefore, chemical companies have been developing laser boosters that can be pre-applied to the garments in order to intensify the effect of the laser to mimic heavier bleaching applications. Unfortunately, laser boosters can create blurred images where the definition is lower and the overall image less natural.

The brand new RUDOLF HUB1922 LASER SMOOTHER is an all-in-one formulation, very easy to pre-apply to garments before laser burning and that return a very natural image which is very similar to the highly desirable hand scraping. Laser smoother can be applied by traditional exhaust or through nebulization and it dries at normal temperature in normal tumble driers.  Advantages of LASER PRIMER are:

•    Remarkable enhancement of the fabric’s characteristics (heightening of material)
•    Overall effect much more natural and similar to manual scraping (craftsmanship dimension)
•    Reduced required laser power to achieve the wanted effect (conspicuous energy saving)
•    A faster laser burning process (significant time saving, depending on the final effect)
•    Any other chemical spray is not required (environmental friendliness)
•    Reduced cost compared to other solution (financial viability)

A. Monforts Textilmaschinen GmbH & Co. KG will demonstrate a range of new advances made possible by Industry 4.0 techniques at ITMA 2019 in Barcelona, Spain, from June 20-26.

At stand D101 in Hall 2, visitors will discover the possibilities of ‘digital twin’ capability – now being made available for all Monforts machine systems – and that by exploiting the latest advanced sensor technology, comprehensive technical machine data can now be virtually mapped in the cloud in real time. The data can be easily accessed using the new Monforts Smart Support and Smart Check apps for an instantaneous status overview. All specifications relating to machine performance and the production process can be mapped, to enable vastly simplified and targeted analysis for controlled planning and production. Insights harnessed from such analysis can be used to optimise the actual production process. At the same time, potential sources of error can be anticipated and eliminated, enabling improved machine availability while considerably minimising downtime.

Parts prediction
In addition, the digital twin system provides information on the individual wear parts of a system, such as, for example, converters or gears. “Operators and mill managers are informed by Smart Check sensors when maintenance or the replacement of key components will be required, well ahead of time,” explains Monforts Vice President Klaus A. Heinrichs. “Direct access to the integrated Monforts webshop allows users to instantly order such parts when they are needed, virtually preventing machine downtime.” On request, Monforts can also virtually monitor machine performance and pro-actively alert customers to the need for preventative action. In such cases, however, data is only ever called from the cloud by Monforts when customers have given their full consent, in the interests of data security. Data from Smart Check, for example, can even be used to analyse a system’s energy requirements, allowing machine operation to be optimised by tailoring production runs to the peaks and troughs of electricity costs.
