In recent years, the fiber and textile industry has been relying more and more on Pure Loop’s variable shredder-extruder solution ISEC evo for recycling production waste, which will be in operation at the trade fair stand. What is more, the Erema Group is to launch the latest development of this recycling machine at this year’s ITMA. The ISEC evo FibrePro:IV has been specially designed for processing PET continuous fibers and fabrics.

“Our ISEC evo machine is a material all-rounder for in-house recycling that is particularly adept at processing fibers and textiles and has already been used for this application many times over. PE, PP, PA, and PET in the form of fiber bales, ropes, filaments, textiles, and nonwovens can be recycled using this shredder-extruder combination,” says Manfred Dobersberger, managing director of Pure Loop, listing some of the system’s special capabilities.

He sees great potential for this technology due to increasing demand in the fibers and textiles segment. Beginning in fiber production, through the spinning process, weaving, and knitting, to clothing production, enormous amounts of production waste are generated along the entire textile value chain. The ISEC evo machine can be used almost universally in terms of fiber types and forms. Together with global partners from the textile industry, Pure Loop is also working on raising awareness of design for recycling. 

“Different types of fibers, such as Elasthan blended with PP, PA, or PET, combined in a garment complicate the recycling process due to different melting points and chemical properties, reducing the quality of the recycled pellets. This is where the industry needs to work together to install better, more circular solutions,” Dobersberger said.

Pure Loop has succeeded in taking a major technological step in this direction in the recycling of PET continuous fibers and fabrics. This is because by combining the ISEC evo machine with an IV optimizer, the quality of the recycled pellets could be increased to such an extent that they can also be used again for very high-quality fiber applications in the textile segment.

The ISEC evo FibrePro:IV is fed with unshredded fiber waste from production processes, and beyond the shredder, it passes in a controlled flow into the extruder and is filtered. After extrusion, the melt is fine-tuned in the IV optimizer to meet the high requirements of the fiber industry. The intrinsic viscosity (IV) is raised to the required level by polycondensation so that the recycled pellets can be used again to make extremely fine fibers. Finenesses of up to two decitex are possible with 100% recycled pellet content. With this top level of quality, the recycled pellets can be used to make filament fibers, carpet yarns, or staple fibers without adding virgin material. 

“Our customers and all those who are interested are welcome to see this for themselves, as we have a demo machine in operation right next to our company headquarters that is available for trials,” says Dobersberger. Pure Loop is particularly proud of an innovative pilot project in the field of fiber-to-fiber recycling of polyester. The successful implementation of this project was possible thanks to the cooperation with RadiciGroup (Italy), a renowned international fiber manufacturer. “Recycling has enormous potential in the fiber and textiles sector. One thing I am sure about is that recycling will become a standard feature within the industry in the future. That is why I am especially pleased that this pilot project, initiated by the Radici Group, sees us taking an important step toward more sustainable production of fibers and textiles. We are proud to have contributed to the recycling technology part of the project with our ISEC evo FibrePro:IV,” says Merlijn van Essen, Sales manager at Pure Loop who has looked after this cooperation.

At ITMA it can also be seen first-hand how easy the ISEC evo shredder-extruder solution is to operate. PP fiber material will be processed by a version without the IV optimizer. Whoever wants to can come and push the start button themselves, in Hall 9, Stand 304.

In 2024, we are looking at full recovery and growth-led investment in Indian printing

Indian Printer and Publisher founded in 1979 is the oldest B2B trade publication in the multi-platform and multi-channel IPPGroup. It created the category of privately owned B2B print magazines in the country. And by its diversification in packaging, (Packaging South Asia), food processing and packaging (IndiFoodBev) and health and medical supply chain and packaging (HealthTekPak), and its community activities in training, research, and conferences (Ipp Services, Training and Research) the organization continues to create platforms that demonstrate the need for quality information, data, technology insights and events.

India is a large and tough terrain and while its book publishing and commercial printing industry have recovered and are increasingly embracing digital print, the Indian newspaper industry continues to recover its credibility and circulation. The signage industry is also recovering and new technologies and audiences such as digital 3D additive printing, digital textiles, and industrial printing are coming onto our pages. Diversification is a fact of life for our readers and like them, we will also have to adapt with agility to keep up with their business and technical information needs.

India is one of the fastest growing economies in nominal and real terms – in a region poised for the highest change in year to year expenditure in printing equipment and consumables. Our 2024 media kit is ready, and it is the right time to take stock – to emphasize your visibility and relevance to your customers and turn potential markets into conversations.
