New modern equipment makes it possible to create the textile innovations of the future

1 March, 2018

Swerea IVF in Mölndal invests in new modern equipment for melt spinning of textile fibres. The equipment is unique in Sweden and will be central in the development of the innovative and sustainable textile fibres of the future.

– Several technical challenges and possibilities ahead lie within fibres that have some form of functionality, e.g. electrically conductive fibres or flame retardant fibres , says Jonas Aspling, department manager, Swerea IVF. Another area of interest which is growing rapidly is fibres from biobased and recycled materials. This equipment will make it possible to emulate large-scale modern fibre production and, above all, help companies to develop new, innovative textile products.

Today, melt spinning is the most common manufacturing technique for textile fibres. The most common polymers used are polyamide (nylon) and polyester. Fibres are spun by pulling melted plastic out in thin strands, which are stretched and allowed to cool, solidify and then wound up on roll. The fibres are stretched in both melted and solid state, which gives the fibres their high strength. The fibres can then be twisted into a yarn used in a garment or in technical textiles.

– Hopefully, the textiles of the future will improve our everyday life and result in great environmental benefits, create new jobs and contribute with innovative products, says Cecilia Tall, chairperson of  The foundation for Swedish textile research. Biopolymers have huge potential as they are a more sustainable way of creating textile materials. We would also like to give TEKO’s members the possibility of accessing ultramodern equipment. Biobased materials have higher demands during manufacturing, which is another reason why the new equipment is needed.

– The equipment we use in our operations today does not provide the quality of the fibres or freedom of design that we and industry need, says Jonas Aspling. Furthermore, it is not suitable for biobased materials, which are more sensitive to thermal degradation and therefore requires stricter control of temperature and shorter processing time. The new equipment will be completely unique in Sweden and only exists in a few places in Europe, Jonas concludes. 

The investment of just over SEK 10 million has been possible through co-funding between an industrial party, the foundation for Swedish textile research / TEKO, TEFO’s Donation fund and Swerea IVF. The equipment will be installed at Swerea IVF during the autumn of 2018.
