UHMWPE fibres – FET’s game changer for the biomedical market

FET is launching the FET-500 Series of gel spinning systems in a move that could revolutionise the research and development of UHMWPE fibres.

Fibre Extrusion Technology Ltd (FET) of Leeds, UK, has built a reputation in medical fibre extrusion technology and innovations, designing and delivering high-performance equipment for a range of precursor medical products, including bespoke extrusion systems for the production of both resorbable and non-absorbable sutures. FET’s equipment supports small-scale, adaptable production and rapid new product development.

In recent years, there has been a growing demand for R&D of UHMWPE fibres. These fibres are prized in many industries due to their extraordinary properties. However, current production processes are complex and focused on the large-scale output of existing fibre grades. This rigid supply chain has stifled innovation in this untapped product market.

The FET-500 gel spinning systems will address this gap in the market. The FET-500 enables a flexible and consistent process, able to produce quality fibres with less than 100 grams of polymer, while avoiding the harsh processing chemicals that were historically associated with gel spinning. The key to unlocking this lab and pilot scale flexibility is the use of supercritical carbon dioxide as a green solvent in a patent-pending process.

Gel spinning starts with extrusion, but the additional washing and drawing technology to produce finished yarn is critical to the overall performance characteristics. An example of the wide range of features and benefits can be shown in the Washing process, with Patent Pending technology using Supercritical Carbon Dioxide:

Extract carrier oil without using toxic, environmentally harmful chemicals such as Hexane and DCM

+++ CO2 is green, cheap, abundant, and significantly safer to work with

+++ CO2 efficiently dissolves carrier oils without affecting the polymer yarn

Reduced operational costs

+++ 9-Vast reduction in solvent use (CO2 vs Hexane/DCM)

+++ Comprehensive oil recovery and recycling

+++ Zero solvent waste is generated, unlike the hexane route

Compact and efficient batch washing system

+++ Recipe controlled plug and play technology

+++ Scalable and adjustable to customer needs

+++ Carrier oil is recovered and fed back to the extrusion process

+++ 80% reduction in factory footprint vs hexane route

FET’s Fibre Development Centre is critical to the inception and success of the FET-500. Having this facility located in Leeds where the manufacturing takes place allows FET to offer a gateway to de-risk, develop and demonstrate the system’s capabilities. FET houses a full demonstration line of the FET-500 to allow customers, existing and new, to visit and experience the system operating from start to finish. We can also aid in developing new products and operating parameters through R&D trials, giving you the confidence and knowledge to transfer a new product offering onto a production line.

FET prepares for final exhibition of 2025

Fibre Extrusion Technology Ltd (FET) of Leeds, UK has completed its second major exhibition of 2025 at ITMA ASIA in Singapore, which is aimed at the textile and garment industry in South and Southeast Asia and the Middle East. Once again, this trade show proved to be a successful one for FET, with considerable interest from several countries surrounding China.

Temco launches a new DTY all-in-one solution

Temco introduces the DTY All-in-One Solution – a fully harmonized set of components engineered to give customers a highly stable, low maintenance and reproducible process environment. The solution reduces interruptions, extends component lifetimes and supports consistent yarn quality across all machine positions. All-in-One Solution – a fully harmonized set of components engineered to provide maintenance and reproducible process environment.

DIENES at Techtextil 2026: Flexible pilot lines for bio-based fiber development

The growing relevance of bio-based materials in technical textiles is accompanied by increasing demands for reproducibility, high-quality data, and scalable process routes. Especially when working with cellulose and its derivatives, chitosan, lignin-based approaches, or bio-based PAN as a carbon-fiber precursor, R&D teams face variable feedstock quality, tighter process windows, and the need for reliable comparability across trials. This calls for flexible, data-driven experimental setups that can be reconfigured efficiently when recipes, solvents, and raw-material batches change.

RETECH showcases high-precision godets for high-performance fiber processing at Techtextil 2026

RETECH designs and manufactures godets and draw frames for heated, ambient and cooled processes, enabling precise heat treatment and consistently high yarn quality for a wide range of polymers and applications, with process temperatures of up to 400 °C for high-performance fibers. The company’s key competence lies in exact and stable temperature and speed control, individually adapted to the specific material and process requirements.

New study shows low environmental impact by Cotton made in Africa Organic Cotton from Tanzania

Today, the Aid by Trade Foundation (AbTF) is announcing the results of a comprehensive life-cycle analysis (LCA) for cotton produced in Tanzania under the Cotton made in Africa Organic (CmiA Organic) standard. The study emphasises the small ecological footprint of CmiA Organic verified cotton. This can largely be traced back to the absence of synthetic pesticides, artificial fertilisers, and artificial irrigation. Consequently, CmiA Organic cotton can help the textile industry meet regulatory requirements as well as science-based targets. The results also show that the consequences of climate change threaten the livelihoods of these cotton farmers, even though the type of agriculture they practise barely contributes to climate change.

PERFORMANCE DAYS proves its relevance as the industry’s key meeting point

Held on March 18–19, 2026, PERFORMANCE DAYS once again confirmed its position as a leading international platform for functional textiles. A total of 3.366 trade visitors and around 560 exhibitors gathered in Munich, with the event already kicking off successfully on DAY 0, which received highly positive feedback for its interactive format. Despite challenging conditions caused by the public transport strike in Munich, the event saw strong attendance and a consistently high level of activity across both exhibition days.
