Litrax showcased smart yarn technologies at ISPO Beijing

Leading Swiss textile technology brand and a producer of functional polymer chips, yarn and textile technologies, Litrax, displayed its latest technology innovations that could change the future of functional garments, at ISPO Beijing last month.

The company showcased L2 Thermo, a fibre integrated warming technology that permits instant warming and insulation of +13°C infrared heat within 10 minutes, produced by the human body itself collected by L2.

This technology received Top 5 and Top 10 innovations awards at earlier ISPO shows, through fabric suppliers LMA and Sampaio Portugal and is in current use by several brands in body wear, insulation and winter and ski wear.

L2 Thermo is available in dark (grey), light (silver) and off-white fibre and filament versions with marginal temperature difference. Off-white still offers a +60 per cent higher temperature as against virgin polyester. This is best for e-vehicles interior (ceiling, carpet, seats), as it will reduce heating battery consumption by 30 per cent.

It claims their technology can warm up even with thinnest socks, and produces a +13°C temperature difference between virgin polyester and L2 Thermo polyester. The company also presented its solution with L14 Conductivity yarns: polymer filaments with finest Swiss made plasma coating of inert Ag/Ti (silver/titanium). The yarns are said to exhibit excellent conductivity properties, are washable and offer total textile flexibility.

“Under normal conditions the comparison between L14 textile electrodes and conventional gel electrodes show no difference of signal strength making it suitable for finest currents in medical, signalling, sensing and lighting applications,” the company added. Litrax presented another novel technology, showing halogen-free L11 Flame Retardant technology for PA6 yarns in both off white and predyed versions with great LOI values.
