Cationic-dyeable yarns have established themselves in the market

The to date largest system for cationic dyeable yarns has been manufacturing in China with great success for over a year now. The installation, with a capacity of 600 tons of POY filament yarn a day, instantly catapults the system operator into the vanguard of cutting-edge producers: with its high-quality products, the well-known Chinese yarn manufacturer has secured itself a 30-percent market share in China.

Energy-efficient yarn manufacture

An additive in the melt ensures easier and superior uptake of dye, meaning that this special type of yarn uses very little water during the dyeing process and hence generates less environmental pollution. As a result of (chemically-) modifying the polymer, the fibers or filaments score points due to the lower temperatures required within the dyeing process, while producing consistently-brilliant dyeing results. The product is visually striking with its extremely-shiny, lively colors. Excellent processing properties – with simultaneously extremely low energy consumption and considerably reduced CO2 emissions – ensure a high level of efficiency in the case of this sustainable product.

The high capacity and the favorable production costs associated with the direct spinning process make the yarn considerably more attractive for further processing compared to production methods available to date. This opens up a new, broader application window for cationic dyeable yarns.

International yarn manufacturers have been producing such yarns within the context of the POY and FDY process on machines and systems supplied by the Remscheid-based solutions provider for 30 years now.

Jeanologia and BCome connect factory data with Life Cycle Assessment and Digital Product Passports

A new white paper by EIM by Jeanologia and BCome demonstrates how primary environmental data from denim finishing processes can be integrated into a garment's Life Cycle Assessment (LCA) and prepared for use in a Digital Product Passport (DPP). A comparative case study highlights significant improvements at the production stage while also showing how these translate into the environmental performance of the finished garment.

Inside the Making connects denim and sportswear supply chains at Ecomondo 2026

Six European companies are joining forces at Ecomondo 2026 in Rimini to demonstrate how different stages of denim and sportswear production are interconnected. The new initiative, Inside the Making, highlights the importance of cooperation across the textile supply chain in addressing sustainability challenges, from reducing resource consumption to improving transparency and the reliability of environmental claims.

EDANA welcomes definitive EU anti-dumping measures on Chinese PET spunbond

EDANA, the international association serving the nonwovens and related industries, has welcomed the European Commission's decision to impose definitive anti-dumping duties on imports of PET spunbond originating in China. The association considers the measures an important step towards restoring fair competition and safeguarding European industrial capacity.

EU imposes definitive anti-dumping duties on Chinese PET spunbond imports

The European Commission has introduced definitive anti-dumping duties ranging from 39.8% to 48.1% on imports of PET spunbond from China. The measures, which entered into force on 31 October 2026, will remain in place for five years and are intended to address unfairly priced imports that have caused injury to European manufacturers. The EU market for these nonwoven materials is valued at approximately €200 million.
