A 3D - printed fibre woven into clothes that can cool down wearers has been developed at the University of Maryland College Park . Researchers are working on the new textile , which can act as a personal cooling system , without any need for an external energy source . They combined boron nitride with polyvinyl alcohol to develop the nanocomposite thread , which is twice as efficient at cooling down wearers as cotton fabrics . The fabric could reduce the need for air - conditioning and so contribute to lowering greenhouse gas emissions .
