Unique FET Spunbond Technology showcased at INDEX20

FET will introduce its new lab-scale Spunbond system at the INDEX20 nonwovens exhibition, stand 1163, taking place in Geneva, Switzerland, from October 19-22.

Complementing the company’s successful meltblown technology, the new spunbond range provides unprecedented opportunities for the scaled development of new nonwoven fabrics based on a wide range of fibres and polymers, including bicomponents.

The market availability of this new technology is particularly timely, given the industry’s current preoccupation with the development of new substrates based on biopolymers, sustainable resins or recycled fibres. FET has already supplied one of these new spunbond lines to University of Leeds in the UK, and a second, in combination with a meltblown line, to the University of Erlangen-Nuremberg in Germany.

MD Richard Slack comments “We look forward to discussing the possibilities of this versatile new system with interested parties at INDEX20 in Geneva,”. “It is capable of processing pure polymer with no requirement for processing aids or additives, to obtain a wide range of structural and mechanical properties, and there are numerous options for the post-processing of the webs.”


New premises update

We are delighted to report that we are well on course to meet the completion schedule for our new premises early next year. The old unit – which was becoming a bit of an eyesore if the truth be told – previously used for storage has now been demolished and the foundations installed on site.

The photograph, taken in August, shows good progress with site preparation and clearance. Construction is now underway and everything is at last beginning to take shape. We are looking forward to a speedy completion to take FET to the next level in our development. The new administration block will certainly help us to maximise efficiency and productivity, whilst the bespoke R&D department and Visitor Centre will be of enormous benefit to our customers in their testing and product development applications.

We will keep you updated regarding site progress over the next few months.


Further gains for FET in the Biomedical sector

FET has now delivered nine meltspinning systems to clients in the biomedical sector since the onset of the Covid-19 pandemic, with a similar number currently on order for 2021/22. This confirms FET’s position as an acknowledged world leader in meltspinning equipment for the production of precursor materials used in medical devices and the default supplier for absorbable suture production systems, with orders virtually doubling year on year.

Managing Director Richard Slack emphasised the long term planning and execution that has contributed to success in this industry. “FET has a long tradition in the highly regulated biomedical sector and we believe our experience is unrivalled. We have built a world leading reputation for melt spinning medical grade polymers in both synthetic resorbable and non-absorbable polymers and FET is now reaping the rewards of this initiative”.

Recent installations include a multi-functional system that can produce both multifilament and monofilament pre-cursor fibres, but nonwoven systems have been particularly prominent, driven by the burgeoning demand for FFP3 masks, gowns and other medical products required during the pandemic. These have been sold to medical device manufacturing companies across the globe, including the Far East, USA and Europe. Research organisations have also invested in FET systems for biomedical applications, the most recent being the University of Leeds in a laboratory scale Spunbond system.

The FET in-house Process Development Laboratory and ongoing collaboration with biomaterial polymer suppliers has helped to optimise the biomedical melt spinning technology.

FET installs new Spunbond system at University of Leeds

FET has completed the installation and commissioning of a new FET Laboratory Spunbond system for the University of Leeds.

This FET spunbond system is now an integral part of the research facilities of the CCTMIH (Clothworkers’ Centre for Textile Materials Innovation for Healthcare), led by Prof. Stephen Russell based in the School of Design, University of Leeds, who commented “The new spunbond system is perfectly suited to our academic research work, and is already proving itself to be extremely versatile and intuitive to use”.

This spunbond system complements existing research lab facilities at the university, which covers all areas of fibre and fabric processing, physical testing and characterisation. It forms part of a wider investment in facilities to support fundamental, academic research on ‘future manufacturing’ for medical devices, where the focus is on studying small-scale processing of unconventional polymers and additive mixes to form spunbond fabrics with multifunctional properties.

Key to this research is developing the underlying process-structure-performance relationships, based on the measured data, to provide detailed understanding of how final fabric performance can be controlled during processing.

As a rule, many exciting materials developed in academic research struggle to progress beyond the bench, because of compatibility issues with key manufacturing processes such as spunbond. By leveraging mono, core-sheath and island-in-the-sea bicomponent technology, the Leeds University team is working with polymer and biomaterial research scientists, engineers and clinicians to explore the incorporation of unusual materials in spunbond fabrics, potentially widening applications.


FET new premises to enable expansion drive

FET has now commenced construction of a new purpose-built Research & Development Centre to enable continued growth. This innovative two-storey development will be situated on the adjacent site, providing state-of-the-art facilities, including a Visitor Centre and enhanced Process Development Laboratory (PDL) for client testing and product development.

Clients frequently spend several days on site participating in development trials and technical sales meetings, so the Visitor Centre is designed to make their stay more efficient and comfortable. Sales, administration and design departments will also be housed in the new building.

The addition of the Visitor Centre will free up a considerable amount of space for production and other facilities in the existing premises. This major refurbishment phase for the existing premises is scheduled for completion at the end of 2021. As a result, FET’s manufacturing capacity will increase by more than 50% to cope with customer demand.

Substantial year-on-year growth has driven this initiative and FET’s current order book in excess of £10million has provided the opportunity for equipping the company infrastructure for the future. Sustainability has been at the forefront of FET’s growth, supporting customers in their development of sustainable textiles and this principle is reflected in the choice of building materials and products for the Visitor Centre wherever possible.

It is expected that the new Visitor Centre will be opened in the first quarter of 2022.
