Collaborative project targeted to SME
- Project full title
- Novel Temperature Regulating Fibers and Garments
Addcomp Holland BV is a partner in the NoTeReFiGa project to develop novel temperature-regulating fibres and innovative textile products for thermal management, selected by the SME segment of the textile industry in Europe. Addcomp is active in compounding novel PCM alloys.
The project aims to achieve temperature regulation by novel methods of incorporating large amounts of phase-changing materials (PCM) in textile fibres. When body temperature increases, the PCM melts and absorbs heat from the body in the form of latent heat. Then, when body temperature drops, the PCM re-crystallizes, and the stored heat is released again.
Garments with built-in thermo-regulating properties maintain thermal comfort during physical activity in difficult thermal environments, without putting on or taking off clothes. Such smart clothing would reduce discomfort caused by accumulation of sweat or moisture in the clothing, and also minimize shivering during varying activity levels and ambient conditions. The innovative concepts to be developed will outperform presently available materials for thermal management.
The concept is based on two main ideas. One idea is based on processing concepts that rely on steps in compounding or mixing to provide suitable rheological properties in complex mixtures of polymers and PCMs, followed by bi-component melt-spinning to produce fibres with a core/sheath structure that confines the PCM to the core. New bio-based polylactic acid (PLA) and conventional synthetic polymers for fibres (PP, PET, PA) are addressed in this part of the project.
The second idea is based on a new concept for incorporating PCMs in wet-spun cellulose fibres based on direct addition of free PCM to a cellulose solution. A large and intense part of the project will be devoted to product related research, lead by the participating SMEs. In particular, specific value-added products are targeted within underwear, sports, leisure, and home textiles. The work will aid in the transformation of the European textile and clothing industry from commodities into specific, value-added, high-tech products.
