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.
