From the Sector

Comber machines from Trützschler are already trusted by customers across the textiles industry and around the globe. The TCO 21 is the latest addition to their portfolio and was built to boost productivity,  ensure quality and support increased automation.

High productivity and raw material savings
One of the key benefits of the TCO 21 is its advanced processing speed. This next-generation combing machine is able to produce at a rate of up to 600 nips per minute. the TCO 21 can also be coordinated with Trützschler’s JUMBO CANS (Ø 1.200 mm). They not only reduce yarn defects due to fewer piecings which leads to quality improvements, but also offer a higher efficiency because of their larger dimensions. This, for example, has positive effects on the number of necessary cans and can transports – and results in lower personnel costs.

Excellent yarn quality
The TCO 21 comes with COUNT MONITORING as standard. This feature makes it possible for the machine operator to define limits for count variations via an easy-to-use display. Trützschler’s DISC MONITOR system of sensors measures the count continuously, and the machine alerts the operator and switches off if the limit is exceeded. In addition, the COUNT MONITORING function also includes spectrogram analysis.

Customers can further strengthen their focus on quality by choosing to add the COUNT CONTROL function to the TCO 21. It is managed via the same easy-to-use display, and offers automatic sliver count measurement, as well as spectrogram analysis. It also automatically regulates the main draft during production to balance count variations and ensure the desired sliver count. This feature is particularly attractive for customers who manufacture blends of cotton and synthetic, as it can also be used to avoid variations in the overall yarn composition.

Automatic optimization
The TCO 21 joins the TCO 12 from Trützschler as an combing machine that offers automatic PIECING OPTIMIZER technology, and that finds the right piecing setting without a single laboratory test, because of two functions: First by adjusting the piecing time in the combing cycle (timing function). Whereas the resetting of the detaching point (piecing time) is usually a very time-consuming task, it now takes only a few minutes and is performed automatically at a push on a button. Second the customer is helped to select specific detaching curve types (curve function) for their unique requirements.

Easy operation
The TCO 21 is simple to operate and maintain. The SMART TOUCH display is fast and intuitive, and a Radio-Frequency Identification (RFID) sensor quickly identifies each user and adapts the information on the display to their individual needs. The multi-colored T-LED display provides visual indications of the machine’s status or quality parameters over large distances which enables the operator recognizing them at a glance in the entire spinning mill. The TCO 21 is built with original Trützschler electronics that ensure high performance and durability: Their intelligent cooling system, that has already proven itself in the draw frame TD 10, contributes to a longer service life by reducing the operating temperature of electronic power components. Even if components have to be replaced at some point, the customer can keep their spare parts inventory small, because they can switch also electronics spare parts flexibly between different machine types, e.g. cards and draw frames. The option to add an automatic greasing function completes the easy operation of the TCO 21.

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

The Lenzing Group reported a significant year-on-year improvement in revenue and earnings in the first nine months of 2021 thanks to the largely positive market environment. Growing optimism in the textile and apparel industry and the recovery in retail led to a substantial increase in demand and prices on the global fiber market, particularly at the start of the current financial year.

Revenue rose by 32.9 percent to EUR 1.59 bn in the first nine months of 2021. This increase is attributable to a higher sales volume as well as higher viscose prices, which stood at more than RMB 15,000 in May thanks to significantly higher demand for fibers, especially in Asia. The focus on wood-based specialty fibers such as the TENCEL™, LENZING™ ECOVERO™ and VEOCEL™ branded fibers also had a positive impact on the revenue trend; the share of specialty fibers in fiber revenue amounted to 72.4 percent in the reporting period. This more than offset the negative impact of less favorable currency effects.

The earnings performance essentially reflects the positive market trend and was additionally reinforced by efficiency-enhancement measures. Energy, raw material and logistics costs increased significantly during the entire reporting period. EBITDA (earnings before interest, tax, depreciation and amortization) more than doubled to EUR 297.6 mn in the first nine months of 2021 (compared to EUR 138.5 mn in the first nine months of 2020). The EBITDA margin rose from 11.6 percent to 18.7 percent. Net profit for the period amounted to EUR 113.4 mn (compared to a net loss of EUR minus 23.3 mn in the first nine months of 2020) and earnings per share to EUR 3.77 (compared to EUR minus 0.1 in the first three months of 2020).

• DiloGroup looks forward to participating in the Techtextil India show 2021.

DiloGroup offers tailor-made production systems from one supplier and will inform at this forum in the German pavillon about its portfolio and the latest equipment developments from fibre opening to the finished felt.

A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further by using the new needle pattern 8000X which is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

The “3D-Lofter” which was first presented during ITMA 2019 in Barcelona offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts are two examples for this technology which explores new application areas for needlefelts.

The 3D-Lofter technology may also be used “inverted” for filling up bad spots in web mats and thus achieves a better homogeneity of e. g. spunlace, thermobond or airlay products. The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

With more than 370 installations delivered to the nonwovens industry worldwide, DiloGroup has the necessary know-how and the complete equipment portfolio to engineer the perfect production line for any product specification. The efficiency of Dilo production lines is the result of long-term research work and experience. Apart from machines for needling technology we offer in cooperation with partner companies also production lines including thermobonding and hydroentangling components.

Reifenhäuser Reicofil will exhibit at the world's leading nonwovens trade show INDEX in Geneva from October 19 to 22, 2021. Under the slogan "Living Nonwovens", the nonwoven line specialist will showcase solutions for the production of sustainable nonwovens for a wide range of applications.

Sustainable nonwoven production starts with the amount of material used - the less raw material needed, the better. The "Reicofil 5x" line series is specialized in this application and achieves fabric weights of 8 gsm (grams per square meter) or even less through efficient downgauging, even on 1000 m/min Composite lines containing 3 Spunbond beams.

In addition, Reicofil customers can reduce the use of fossil raw materials on request by processing biobased raw materials as an ecological alternative - for example for diapers. The topsheet material, made of bulky, soft, and industrially compostable high-loft nonwovens, meets maximum hygiene requirements at the same time.

For industrial applications, high-strength nonwovens can be processed even from up to 90% PET flakes from post-consumer waste. This is how Reicofil shows ways to combine sustainability and high-performance nonwovens.

In the medical sector, the line manufacturer will also be exhibiting its leading solutions for high-barrier medical protective clothing. In addition, meltblown nonwovens for face masks - still in great demand in many regions due to Covid - provide reliable safety and are helping to combat the pandemic worldwide. Reicofil technology therefore guarantees maximum safety, with filtration efficiencies of up to 99% (N99 / FFP3 standard), minimum quality fluctuations, and extremely high line availability at the same time.

With the current RF5 machine generation, Reicofil also sets benchmarks in terms of quality, performance, availability, efficiency, and machine intelligence - for challenging applications in hygiene, medical, and industrial sectors.

Global energy consumption reached a record high in 2019, following a 40-year trend for rapidly increasing energy demand that was only halted by the Coronavirus pandemic. It’s estimated that more than 80 % of this energy is still generated from fossil fuels that produce CO2 emissions and contribute to climate change. Renewable energy offers a solution to this problem, but saving energy whenever possible is an even more effective approach. That are the motives for Trützschler to develop the intelligent card TC 19i, which sets a new benchmark for energy-efficient carding.

The intelligent Trützschler card TC 19i features the unique T-GO gap optimizer, which continuously and automatically monitors and adjusts the carding gap to an ideal position during production. Innovative drive- and air technology further reduce energy consumption of the TC 19i.

The most energy-intensive elements in a carding machine are the drive, the dust suction process and the compressed air system. Permanent suction is needed to remove dust and cotton waste in key places. Smart optimization of these areas has made the intelligent card TC 19i a benchmark for energy efficiency in carding because it uses less electricity, lower suction pressure and less compressed air than other machines, while providing the highest production rates currently available on the market.

In a head-to-head comparison between the TC 19i and a high-performance card from a competitor, the TC 19i consumed at least 10 % less energy per kilogram of material produced when manufacturing rotor yarn from a cotton and cotton waste mix. The compared energy values included electric power consumption and energy required for suction and compressed air and were measured in both cards at the same production of 180 kg/h. A 10 % reduction in energy per kilogram of sliver produced, as proven here by TC 19i, can have a significant impact on a spinning mill’s profitability; annual savings worth a five-digit sum are frequently possible, depending on factors such as the output of the mill. The customer trial also showed TC 19i’s excellent reliability at the customer’s usual production rate of 180 kg/h, and even demonstrated stable performance at 300 kg/h in the same application. Because the TC 19i with T-GO gap optimizer realizes maximum production rates at no compromise in quality, manufacturers can reduce their energy demand and investment costs drastically: Less machines are needed to achieve the desired output, and energy consumption per production is reduced.

This improvement was made possible by a long and sometimes challenging innovation process involving mathematical models of air flows, as well as flow simulations and prototypes. By combining the final flowoptimized parts in the TC 19i, Trützschler’s experts have developed a card that operates with suction pressure of just -740 Pa and with an air requirement of only 4200 m³/h. This translates into 40 % less energy demand for air technology compared to the latest high-performance competitor model.

EURATEX published their vision on the EU Strategy on Sustainable Textiles, reflecting the views of the European textiles and apparel industry. The goal is to promote a competitive and sustainable industry. to do so, wanting to be a global leader on sustainable textiles, the efficiency of the industry must be increase as well as the global market share.

The enclosed document presents 15 action points on how to achieve these targets.
