TBM and Bioworks have collaborated with SHIMA SEIKI MFG., LTD. and achieved a mask design that is comfortable and easily fits the shape of a face, by knitting masks three dimensionally with the WHOLEGARMENT machine (the seamless knitting machine of SHIMA SEIKI MFG.) etc., using the PLA yarns developed through collaborations among the three parties. TBM and Bioworks plan to start producing Bio Face masks in and outside Japan, from June 2020. In addition, TBM and Bioworks are developing an antivirus mask filter, targeting to launch in June 2020. TBM and Bioworks have started accepting pre-orders for Bio Face masks.
