Focus on eccentric screw pumps and pumps for shear-sensitive materials

Improved productivity and increased lifespan and tailored solutions also for the most demanding applications within the chemicals and plastics industries and in PUR applications – these are the convincing arguments with which Oerlikon Barmag is showcasing its precision metering pumps at this year’s ACHEMA between August 22 and 26, 2022 in Frankfurt. The focus is on the new pump for shear-sensitive conveying media and the new eccentric screw pump.

Eccentric screw pumps – robust all-rounders convey any medium
The requirements for pumps are considerable, as the demand for customized solutions for increasingly complex processes is rising. This is particularly true for Oerlikon Barmag’s new eccentric screw pump range. High wear-resistance, increased durability and robust operation – the new pump is tailor-made for conveying highly-filled, high-viscosity and abrasive media, such as filled adhesives, filled silicones and filled casting compounds, for example. The is the multi-stage seal system, which considerably increases the pump’s lifespan. The upstream shaft sealing ring protects the slide ring seal against excessively-fast wear caused by challenging media. In turn, the optimum alignment of the drive shaft – ball bearing-supported and centrally-guided through the shaft sealing ring – prevents any metal debris caused by friction and hence ensures considerably greater durability. Producers benefit from considerably greater productivity, as the pumps’ maintenance intervals and hence machine downtimes are significantly reduced.

New pump for shear-sensitive materials
For increasingly complex customer-specific process solutions, Oerlikon Barmag is now expanding its GA series, developed especially for the challenging conveying of high-viscosity media, to include the GAB51F for shear-sensitive conveying media. The newly-developed pump with its viscosity range of max. 300 Pas is tailored to conveying high-viscosity, shear-sensitive materials such as adhesives and silicones, for example. “The shear forces impacting the medium within the pump are reduced to a minimum as a result of a specially geometry”, explains Thorsten Wagener, Senior Sales Manager within the Pump Construction business unit. The material is conveyed through the pump in an as gentle and low-pulsation manner as possible and metered precisely at the outlet – ensuring it retains its characteristic properties.

High-speed metering pump with sealed product space
The high-speed metering pump has been especially developed for metering poorly-lubricating media. Here, the main benefit is the sealed product space, which extends the pump’s lifespan considerably. The space that comes into contact with the media is limited to the area around the gears. “As a result, the high-speed pump is particularly suited for applications in the chemicals industry, which frequently involve aggressive acids”, comments Thorsten Wagener.

GM series for low-viscosity media
The pumps in the GM and GA series provide precision metering with low-pulsation feeding of the conveying medium. The multi-stage GM pump conveys low-viscosity media (i.e. 250 bar, 100 mPas) even under high pressure and in the most challenging conditions. The square design from the proven GM series is the standard pump for many metering tasks. The development of the multi-stage pump expands the applications range for the GM series considerably. The round 2-stage GM pump has been developed especially for use in high-pressure technology. It masters the particular challenge of conveying small throughputs with low viscosities. The pump is perfect for 0.05 through 20 cm³/rev feed sizes and is excellently suited for use in high-pressure machines for PUR molded parts, foam slab stock, refrigeration unit insulations and sandwich panels, for example.

GA series pumps for high-viscosity media
The Oerlikon Barmag GA range has been especially developed for the challenging conveying of media with higher viscosities. The GA series pumps are available for conveying volumes of between 1.25 and -30 cm³/rev (0.6-144 l/h). They have been designed for pressures of up to 200 bar, for viscosities of up to 1.500 Pas as well as for temperatures of up to max. 225 °C. With this range of pumps, Oerlikon Barmag offers its customers tailor-made solutions for many technical processes in which high-precision and even metering is of paramount importance.

The drum pump – conveying and metering using a single unit
With the drum pump, the Oerlikon Barmag pump specialists have created a pump designed specifically for conveying and metering high-viscosity materials such as adhesives, silicones and other high-viscosity materials from drums and other large containers and for pressures of up to 250 bar. Its special features not only include the fact that it removes high-viscosity materials from the drum, but that it also meters the medium directly without any additional interim stops.

Huntsman Textile Effects, a global leader in innovative solutions and environmentally sustainable products, will be at Outdoor Retailer in Denver, Colorado this week to present end-to-end solutions that enable outdoor apparel brands to achieve the functionality that outdoor adventurers crave with on-trend aesthetics and a high degree of sustainability.

Resource-saving solutions
Huntsman will highlight the AVITERA® SE Fast process. This technology delivers the lowest environmental impact for dyeing polyester-cellulosic (PES-CO) blends. It combines alkali-clearable TERASIL® W/WW disperse dyes and AVITERA® SE reactive dyes to cut processing time from around nine hours to just six, helping mills to reduce the water and energy required for production by up to 50% and to increase output by up to 25% or more. The new process also delivers outstanding wet-fastness to ensure that sportswear will not bleed or stain during home laundering or while in storage or transit.

EROPON® E3-SAVE is another next-generation water-saving innovation. An all-in-one textile auxiliary for PES processing, it allows pre-scouring, dyeing and reduction clearing to be combined in a single bath and eliminates the need for anti-foaming products, which shortens processing time and further saves water and energy.

Eco-friendly stain and rain resistance
Huntsman will also present eco-friendly finishes that repel water and stains to help garments look new for longer. Continuing its long-standing relationship with Chemours, Huntsman is highlighting Teflon™ EcoElite with Zelan™ R3 technology. The industry’s first renewably sourced water-repellent finish, it contains 63% plant-based materials and exceeds performance levels possible with traditional fluorinated technologies, preserving breathability while offering excellent water repellency and durability.

Another breakthrough for brands and mills is PHOBOTEX® RSY for outerwear. A next-generation non-fluorinated water-repellent finish, its performance is comparable to formulations based on per-fluorinated chemicals (PFCs), delivering sustainable protection that keeps the wearer dry, even in the most demanding environments. It is a perfect combination of excellent water repellency and extremely high wash durability.

Innovative odor control solutions
Huntsman will also showcase antimicrobial and odor-control solutions as part of its partnership with Sciessent. Sciessent’s latest anti-odor technology, NOBO™, has been specifically developed to reduce odors in natural and synthetic fabrics. It can be incorporated into virtually any fabric, making it ideal for everything from base layer and activewear tops to socks and underwear to hiking pants, chinos and hard shell jackets. It offers a cost-effective way to upgrade everyday garments.

In addition, the partners will also present Sciessent’s Agion Active X2®, a next-generation odor-control solution that combines advanced antimicrobial and odor-absorbing technologies to both capture and fight odor-causing bacteria, and Lava X2®, a standalone odor adsorption product and key component of Agion Active X2® that attracts, adsorbs and degrades odors for long-lasing odor protection.

adidas launches its SS22 Tennis Collection, a high-performance tennis apparel line featuring graphics inspired by Paris’ botanical gardens and green spaces, garments in the collection were made either in part with Parley Ocean Plastic or in part with recycled content.

Launching ahead of the most prominent clay court tournament of the summer, the SS22 Tennis Collection is being premiered on court by adidas next-gen athletes, Elena Rybakina and Felix Auger-Aliassime, alongside Maria Sakkari, Dominic Thiem and Stefanos Tsitsipas who all share a passion for championing sustainability and working together towards a better future for our planet.

From Insight to Action
The SS22 Tennis Collection is another step adidas is taking on its journey to help end plastic waste, and its athletes are sharing this commitment. For adidas athletes, what they wear on the court is not only performance attire but an expression of their personal style and beliefs.

Felix Auger-Aliassime, elite tennis player, commented: "I'm part of a generation of players who care about having an impact on and off the court. When I think about the future, it's not just about my future as a tennis player, but also about the future of the planet. . That's why I wear the new adidas SS22 collection made in part with Parley Ocean Plastic or in part with recycled materials – to send a message that we can all do our part by helping to end plastic waste.“

Fashion-foward Performance
The SS22 Tennis Collection is designed to be bold yet fully functional on court. Each garment features HEAT.RDY technology which is designed to keep players feeling cool, dry and confident as they take on their next challenge.

The Collection features two dresses, tank tops, long sleeve tees and a match skirt for female players. For male players, the collection consists of two tees, a sleeveless tee, a polo tee, a TECHFIT long sleeve top and two different types of shorts.

It is available in a number of different bold graphic prints, all inspired by the Serres d'Auteuil botanical garden. The prominent colors of the collection are black and white.

The EREMA Group, which comprises EREMA Group GmbH and its subsidiaries EREMA, PURE LOOP, UMAC, 3S, KEYCYCLE and PLASMAC, closed the 2021/22 financial year with a 17 percent increase in revenue. Consolidated Group revenue amounted to EUR 295 million, and the number of employees increased to over 840. The EREMA Group remains on course for continued growth.

A closer look at the post consumer segment clearly shows a trend towards larger plants, both for PET recycling and for processing polyolefins. For example, the first VACUREMA® Basic 2628 T machine with an annual capacity of up to 40,000 tonnes was recently commissioned at a customer's site in Brazil. This plant features a ten-meter-long special geometry screw with a diameter of 280 millimetres and a weight of 3.5 tonnes. The screw was developed and manufactured by 3S, a subsidiary of EREMA GmbH.

Demand for previously-owned machines at UMAC also remained high during the past financial year. In addition to the general trend towards plastics recycling, the decisive factor here is that customers are more frequently opting for previously-owned systems available at short notice due to the tense situation on the procurement markets. At the same time, businesses that have so far had little contact with recycling are also becoming increasingly interested in this topic. Their need for feasibility studies, consulting and engineering services, project management and turnkey projects are now also very successfully catered for by KEYCYCLE, an EREMA Group company. KEYCYCLE has also acquired from Cadel Deinking the patent, technology and distribution rights for an innovative ink removal technology, which is now being further developed using the know-how of the EREMA Group and shaped into a product that meets industrial standards.

The initiative launched four years ago to modernise and expand existing EREMA Group sites was continued during the past financial year with the expansion and construction of a dedicated machine demonstration centre for PLASMAC in Milan. Equipped with additional production floor space and new and enlarged customer centres, all companies within the group are now well prepared to meet rising demand, and with the new research and development centre under construction in Ansfelden, the framework for further outstanding plastics recycling milestones from EREMA is currently being optimised.

• Exceptionally high order backlog and sustained strong demand
• Supply chain bottlenecks, COVID lockdown in China and significant cost increases
• Takeover of winding machine business leads to additional costs
• Sales and earnings adversely impacted in first half-year
• Considerably improved market position

Despite an exceptionally high order backlog and sustained strong demand, Rieter’s business situation in the first half of 2022 is characterized by the well-known supply chain bottlenecks, the repercussions of the COVID lockdown in China and the significant increases in material and transportation costs.

Further costs are added in connection with the takeover of the automatic winding business as of April 1, 2022.

These factors are adversely impacting both sales and earnings.

Rieter expects significantly higher sales in the first half of 2022 compared to the prior-year period (first half of 2021: CHF 400.5 million). Rieter anticipates a loss at the EBIT and net result level in the first half of 2022 (first half of 2021: EBIT CHF 9.0 million, net result: CHF 5.3 million).
The company is working intensively on the implementation of measures to minimize the impact of the supply chain bottlenecks, the COVID lockdown in China and the cost increases. The implemented price increases have a delayed effect, particularly in the machinery business. The integration of the automatic winding business is proceeding according to plan.

As soon as the situation in the sourcing markets has normalized, Rieter expects to benefit from the exceptionally high order backlog and the considerably improved market position as a result of the takeover of the automatic winding business as well as Accotex and Temco.
Rieter will provide a detailed report on the business results of the first half of 2022 in July 2022.

International textile producers meet again in Istanbul, Turkey, from June 14 – 18, 2022 on the occasion of the ITM + Hightex Exhibition. In Hall 9 (Hightex) the exhibitors will present the complete industry value chain from nonwovens raw materials, production machines and accessories to the endproduct. The related industries covered include hygiene, filtration, fabrics and apparel, medical, automotive, wipes, home furnishings and upholstery. DiloGroup offers tailor-made production systems from one supplier and will inform about its portfolio and the latest equipment developments from fibre opening to the finished felt.

DiloGroup will inform about complete lines as well as high speed needlelooms for spunbonds. 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. The new needle pattern 8000X is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

Another strong pillar of the sales program over decades has been fibre preparation and high speed webforming equipment for other nonwoven technologies. The further development of the high-speed layering principle “Hyperlayer” made progress for better CD strength through a combination of inline cards and crossline card with crosslapper. Particularly, carding machines in a working width above 3.5 m up to 5.1 m have been supplied by DiloSpinnbau as complete high speed carding systems, comprising two or even three cards in a line to directly feed the hydroentangling units of various suppliers. Together with DiloTemafa not only have high throughput rates been achieved in the fibre preparation section of the line but also dedusting filtering and air-conditioning systems have been successfully engineered and integrated.

Together with Sicam, Dilo has combined know-how for hydroentangling technology and therefore can provide complete lines as general contractor including equipment for cutting, winding and packaging.

Another interesting machine is the 3D-Lofter, first presented during ITMA 2019 in Barcelona, which 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 with or without repeat are two examples for this technology which explores new application areas for needlefelts.
The 3D-Lofter technology may also be used “inverted” as “IsoFeed” for filling up bad spots in web mats and thus achieves a better homogeneity of spunlace 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”.

A boundary-pushing approach to hacking carbon reduction challenges has been established by AkzoNobel and partners from across the extended value chain following the company’s first ever global Collaborative Sustainability Challenge.

During 24 hours of intense discussion at the pioneering event a series of high impact exploration teams was set up. Those involved will now continue to work together in a determined effort to collectively accelerate the reduction of carbon emissions in the paints and coatings industry.

The participants – represented by senior and next generation leaders – hacked four key areas: energy transition, process efficiency, solvent emissions and circular solutions. It resulted in 27 partners signing up, including suppliers, customers and end-users, as well as representatives from finance, government, service providers and consultancies.

AkzoNobel has set science-based sustainability targets to halve its carbon emissions across the full value chain by 2030. Achieving that ambition will rely heavily on collaborating with partners and challenging each other to find innovative ways to overcome the unprecedented challenges everyone faces.
