From the Sector

• Spunbond, meltblown and composite structures for new market opportunities

RadiciGroup is participating with its Advanced Textile Solutions business area at Index in Geneva from 18 to 21 April 2023. Among the Group’s products showcased are spunbond and meltblown for different application sectors, such as roofing, construction, automotive, HO.RE.CA. and filtration.

“The key message we are bringing to the fair is sustainability,” noted Enrico Buriani, CEO of the Nonwovens division of RadiciGroup Advanced Textile Solutions. “Those who already know us know that, for many years, the Group has been focused on proposing low environmental impact products and processes where sustainability is scientifically measured or certified by independent third parties. Our company is dedicated to nonwovens, which, by the way, are produced using 100% renewable energy. We have expanded our portfolio of innovative solutions for customers interested in realizing projects with sustainability as an essential requirement.”

Respunsible® is a spunbond brand manufactured from recycled polypropylene. A preliminary Life Cycle Assessment (LCA) study was carried out by RadiciGroup to demonstrate the correlation between the reduction in environmental impact and the percentage increase in recycled material. The final results demonstrate that a variable percentage of from 50 to 70% recycled material leads to a reduction in CO2 emissions of from 30 to 40%, compared to a fabric made of 100% virgin material, without comprising high technical performance.

Additionally, since RadiciGroup has achieved ISCC PLUS certification (International Sustainability and Carbon Certification), it can offer bio, biocircular or circular polypropylene spunbond and meltblown nonwovens, in which the sustainable polypropylene is biomass balanced. This certification signifies traceability along the supply chain and verifies that the certified companies meet high environmental and social standards.

“Since 2020, we have had a technologically advanced meltblown production line,” Mr. Buriani concluded. “This allows us to make composite structures, sold under the brand name Radimelt®. Now our goal is to expand our filtration applications, diversifying and developing new business, for instance vacuum cleaner bags or HVAC (heating, ventilation and air conditioning) system filters, where we can meet the high efficiency and mechanical resistance demanded, thanks to our latest generation technology.”

A delegation from TMAS, the Swedish textile machinery association, will participate in the forthcoming Febratex textile show which is being held in the German Village Park in Blumenau, in Santa Catarina, Brazil from August 23-26.

As the fourth largest textiles manufacturer in the world, Brazil’s annual revenues from textiles and apparel amount to an annual $48 billion and the industry employs around 1.5 million people directly.

As with the USA and many European countries, product shortages resulting directly from the Covid-19 pandemic, and subsequent supply chain difficulties, have emphasised to Brazil’s industry the attractiveness of more diversified and shorter supply chains which are closer to customers wherever possible. In the past two years, there has been less reliance on imports from Asia to Brazil, and opportunities are arising again for local manufacturing.

Svegea of Sweden has supplied many automatic collarette cutters to Brazilian companies, which are used by garment manufacturers around the world for the production of tubular apparel components such as cuff and neck tapes and other seam reinforcements.

Svegea supplies many other bespoke machines for applications in the production of both garment components and technical textiles, including rewinding, measuring, inspection and band knife machines.

Eton Systems, the inventor and world’s leading provider of automated production systems for apparel and other textile-based processes, has supplied a large amount of workstations to Brazilian companies over the years, and believes its newly-launched Opta system is good news for this market becoming more efficient and profitable.

Automation is also high on the agenda of ACG Kinna Automatic, which specialises in automation solutions for filled products such as quilts, pillows and mattresses and also has extensive knowledge in areas such as bed linen and textile filters.

Given Brazil’s extensive forestry sector, the country is a key market for Texo AB, one of the world’s leading manufacturers of weaving machines for the production of paper machine clothing (PMC).

All paper manufacturing machines require a regular supply of PMC, which as large continuous engineered fabrics, carry the paper stock through each stage of the paper production process. With technologically sophisticated designs, they employ fibres and other polymeric materials in complex structures and each paper machine has an average of ten separate fabrics installed on it. Although the PMC business represents just a small proportion of the total cost of manufacturing paper, it can have a significant impact on the quality of the paper, the efficiency of a machine and machine production rates.

Production units with latest joining technologies for the filtration industry

The core competence of PFAFF Industriesysteme und Maschinen GmbH is the joining of flexible materials. The company not only masters industrial sewing applications, but has also been an innovation leader in textile welding applications for decades. Depending on the material and customer requirements, customer solutions are implemented using the ULTRASONIC, HOT-AIR or HOT WEDGE welding methods. In addition to the classical industries such as 'clothing, shoes, home and car upholstery', the company has made a name for itself as a specialist supplier of production solutions for the filter industry. Whether it be filters for dry filtration (dust removal, air conditioning and ventilation technology) or for liquid filtration, such as pleating filters, tube filters, stocking filters, pocket filters, bag filters, etc., the articles must first be assembled. In close dialogue with the customer, PFAFF defines the right joining technology and implements this in the machine or production line.

With the brands PFAFF INDUSTRIAL and KSL, the company has the necessary experience in process engineering, electrical engineering, automation technology and robotics to meet customer requirements for reliable, partly fully automatic solutions. A fully automatic production line for the manufacture of filter bags (with longitudinal seams) for an Asian customer is currently being manufactured in Kaiserslautern/Germany. At the heart of the system are the exchangeable hot-wedge welding and 3-thread chainstitch sewing units. Depending on the application, these can be implemented in the manufacturing process in just a few minutes. The raw material is unrolled, precisely formed and quickly and reliably fed to the sewing or welding unit. After joining, the 'tubes' are cut (filter length selectable via display) and automatically ejected. Optionally, the parts can be labelled using a printer. Depending on the material, the plant reaches a production speed of 10m/min.
