Non-contact precision spray technology enhances productivity, sustainability and process control

Baldwin Technology Company Inc. has announced that it will showcase the TexCoat G4 non-contact precision spray fabric finishing system at the Techtextil North America tradeshow, held from May 12 to 14, 2020, in Atlanta (booth #3048).

With extensive sustainability benefits, unprecedented tracking and process control, and industry 4.0 integration, the TexCoat G4 provides consistently high-quality fabric finishing, with no chemistry waste, as well as minimal water and energy consumption. 

Baldwin’s innovative non-contact spray technology eliminates chemistry dilution in wet-on-wet processes. The TexCoat G4 consistently and uniformly sprays chemistry across the fabric surface and applies it only where needed, on one or both sides of the fabric. Customers can expect no bath contamination during the finishing process, as well as minimal downtime during changeovers, which are made easy with recipe management that includes automated chemistry and coverage selection.

The TexCoat G4 also enhances sustainability by wasting no chemistry during color, fabric or chemistry changeovers, and because only the required chemistry volume is applied to the fabric, wet pick-up levels can be reduced by up to 50 percent—leading to 50 percent less water and energy consumption. Furthermore, in single-side applications, drying steps can be eliminated for various textiles, including those that are back-coated and laminated, thereby streamlining and simplifying the production process.

Following its installation at several major yarn manufacturers in China, the first wiping robot has now been operating in India since the end of 2019. As already the case with our Chinese clients, the performance of the Oerlikon Barmag solution there demonstrates the same properties: an even, high-quality wiping process providing considerably reduced yarn break rates and higher full package rates. Regular wiping (cleaning) of the spin packs is important for process stability and yarn quality.

The performance data at the Indian yarn manufacturer was collated and evaluated over a period of three months. The results revealed that the yarn break rate has – regardless of the product – fallen by almost 30%. The former running time breaks have decreased by 10% and string-up breaks by 40%. Consequently, full package rates have risen by 3%, while waste rates have fallen by 0.2%. “Yarn breaks are always an issue; they have a direct impact on the production figures. This is where the wiping robot reveals its added value”, comments Stephan Faulstich, Technology Manager POY. The system automatically and autonomously controls the individual positions in accordance with the scheduled wiping cycles. In addition to the scheduled wiping processes, there are also events that cannot be planned or that are not immediately visible. Here, the wiping robot – as a result of its management functionalities – is able to identify issues such as yarn breaks or parallel wiping processes and to independently offer solutions. The same also applies to manual requests: if another action is simultaneously required here, the system identifies this and offers solutions.

The wiping robot operates in a cross-line manner. In contrast to manual wiping, the cleaning quality remains constant around the clock, considerably reducing the impact of the wiping on both the spinning plant process stability and on the yarn data of the spun yarn. And production times can be increased between two cleaning cycles as well: whereas repeated wiping is required after 48 hours in the case of manual wiping, utilizing the robot extends the interval between two wiping processes to up to 60 hours. The considerable increase in the spinning process efficiency achieved by the wiping robot also has a positive impact on margins. To this end, one customer deploying the wiping robot was able to reduce its production costs for the same yarn by more than 3%.

• Investment of Rp. 15 trillion (USD1,1 billion) in facility
• Supports development of national textile industry and ‘Making Indonesia 4.0’ roadmap

The President of Indonesia, Joko Widodo, today inaugurated Indonesia's largest integrated viscose rayon production facility, injecting a boost for the country’s textile sector and the Indonesian Government’s industrial 4.0 development strategy.

The new Asia Pacific Rayon (APR) facility is located in the same production complex as APRIL Group in Pangkalan Kerinci, Riau province, Sumatra. This co-location allows integrated operations where renewable plantation pulp supply from APRIL feeds directly to APR for viscose rayon production. The new operation represents a total investment of approximately Rp.15 trillion (USD1.1 billion).

The APR facility has an annual production capacity of 240,000 tons. The inauguration ceremony included the signing of a plaque by President Widodo and the symbolic sealing by the President of an export container with 10,190 tons of viscose rayon fibre for shipment to Turkey, one of APR’s key export markets, and another 12,000 tons to Central Java.

The ceremony was also graced by the Minister of Industry, Agus Gumiwang Kartasasmita, the Minister of Trade Agus Suparmanto, the Governor of Riau, Syamsuar, RGE Founder and Chairman Sukanto Tanoto, and Anderson Tanoto, Director, RGE.

Speaking at the inauguration, President Widodo welcomed APR's investment in the development of the national textile industry. The role of the private sector was influential in driving economic growth, alongside the stimulus provided by the Government, he said. “Our garment industry should be greater than Vietnam. We already have our own raw materials here, such as viscose rayon, to support the industry,” he said.

Economic Contribution
APR’s business aligns with President Jokowi's vision to encourage more value-added investment in the nation and the strengthening of the national textile and textile product (TPT) industry, as set out in the Making Indonesia 4.0 Road map. In addition, the production of viscose rayon will reduce dependence on the import of textile raw materials, particularly cotton, to meet domestic demand.

Agus Gumiwang Kartasasmita, Minister for Industry, said: “By optimising the availability and use of raw materials originating from Indonesia, we can boost the performance of our textile sector. This is just one of several steps we are taking to continue to improve the performance and competitiveness of the labour-intensive industry.”

Basrie Kamba, Director APR, said: “The presence of APR will have a positive impact on employment and business opportunities for small and medium-sized businesses in the upstream and downstream sectors of the textiles and textile products industry. We are honoured and grateful to President Jokowi for inaugurating our new facility”.

In addition to Turkey, APR’s products are exported to 14 other countries including key textile centres such as Pakistan, Bangladesh, Vietnam, Brazil, and various parts of Europe. The products also support an expanding Indonesia fashion industry.

It is estimated that APR may generate foreign exchange revenues exceeding Rp1.77 trillion (USD130 million) annually, and reduce dependence on imported raw materials by about Rp2.01 trillion (USD149 million) annually.

Sustainable Production
APR produces sustainable viscose rayon fiber from renewable, traceable and biodegradable raw materials. The company’s raw materials are supplied by APRIL Group, which is recognised as a responsible pulp producer through national (Timber Legality Verification System) and international (Program for the Endorsement of Forest Certification/PEFC) certifications.

APR is the first viscose rayon manufacturer in Indonesia to receive the internationally recognised STeP certification from OEKO-TEX ®, an independent Swiss-based certification organisation, for the responsible manufacturing of viscose staple fibre.

APR has launched the ‘Everything Indonesia’ campaign to promote the sustainable sourcing and production of fashion from Indonesia. The aim is to support Indonesia’s resurgence as a global centre for textile manufacturing, and catalyse home-grown fashion design and creativity.

Monforts customer Rajby Textiles is the first company in the world to have finally achieved the Cradle to Cradle (C2C) Platinum Standard for a product. Its Beluga denim fabrics have gained the ultimate sustainability score in all five categories covered by the C2C standard, which is acknowledged as involving the toughest and most thorough testing and assessment it is possible to put a product through.

As such, Beluga denim fabric is based on 100% GOTS certified organic cotton and employs no hazardous chemicals in its production. At the same time, it is both recyclable and biodegradable, with 100% of the energy used in its production offset by green energy and involving a closed loop system with no waste water generated and no material wastage.

The new Beluga denim fabrics, however, represent a new zenith in circular denim production. To meet the active cycling requirement, Rajby has committed to using Beluga denim fabric exclusively in apparel products sold by retailers with take back programmes in place and estimated expected cycling rates for such products

In the latest technology innovation from members of TMAS (the Swedish textile machinery association), ACG Kinna and ACG Nyström have teamed up with Juki Corporation – the world’s leading sewing machine manufacturer – in the development of a new automated line concept that can considerably speed up the production of finished filter bags.

Woven or nonwoven filter bags employed in a wide range of industrial processes may be under the radar as products, but they represent a pretty significant percentage of technical textiles production.

According to a recent report from BCC research, a leading US analyst covering this sector, industrial filtration represented a $555 million market in 2019 and some of the key areas where such filter bags are employed include:

• Metal fabrication, with effective filtration required for manual and automated welding, thermal cutting, blasting and machining, especially for coolant filtration.
• The process and energy industries, including foundries, smelters, incinerators, asphalt works and energy production plants.
• Other key manufacturing fields – often where dust is generated – including the production of timber, textiles, composites, waste handling and minerals, in addition to chemicals, food production, pharmaceuticals, electronics and agriculture.

Line integration
The new SFL-2000 line is the result of a four-year development project between Juki Central Europe, headquartered in Poland, and the two ACG companies.

It is capable of handling a wide range of different filter media, and as an all-in-one solution, can produce high quality and accurate seams to pre-defined parameters, with optional modules allowing for customised constructions.

Hexcel is collaborating with NaCa Systems, a Tier 1 supplier of natural fiber composite automotive interior parts, on the development of a lightweight carbon fiber prepreg and wood fiber composite sportscar seat back using a rapid press molding process. This innovation validates a short cycle time production process for CFRP and wood fiber composite parts and offers a host of benefits to automotive manufacturers.

Hexcel supplies NaCa Systems with an optimized version of its HexPly® M77CS epoxy prepreg material. HexPly® M77CS is a fast curing hotmelt, thermosetting epoxy matrix, specifically designed for prepreg applications for which short cure cycles and clear surfaces with perfect aesthetics are required.

The lightweight seat back demonstrates a 40% weight saving compared to a typical injection molded plastic component whilst also featuring a significantly improved CO2 footprint vs a full carbon part. The prepreg and wood fiber structure doesn’t produce sharp edged pieces when damaged. In addition, wood fiber composites also increase sound absorption, contributing to improved NVH damping within the vehicle interior.

The NaCa Systems seat back will be on display on the Hexcel stand at JEC World 2020.

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.
