While khaki is commonly used to describe a spectrum of different shades, from yellowish light brown to deep olive green, it is originally an Urdu word meaning ‘dust-coloured’. Khaki was developed by the British military in the 1840s, while occupying what is now Pakistan, as an alternative to their traditional red uniforms. Drab clothing allowed the soldiers to better blend in with the desert landscape. By 1884, the colour was used across British regiments and soldiers were called ‘khakis’ because of their uniforms. Queen Victoria declared it ‘hideous’ – but it worked.
Mud, mulberries, coffee and curry is said to have been used to produce the desired shade. But it was a dye prepared from a local palm tree that finally stuck. When camouflaging khaki uniforms were moved out of their desert origins and adopted by armies around the world at the turn of the 20th century – by the U.S. in Southeast Asia and by European nations in the first world war – the shade had become green rather than beige.
Through an advanced recycling process where nylon waste is broken down and returned to its original building blocks, it is possible to rebuild a completely new nylon fibre with the exact same purity and performance as virgin nylon, without the use of raw fossil materials. Nylon is a synthetic textile fibre that can be recycled endlessly with retained quality, and the ECONYL® Regeneration System thus forms a closed-loop cycle of regenerated – and regenerable – nylon products.
The making of ECONYL® yarn starts with the rescue of waste and surplus materials that otherwise would have been unused or gone to landfills. Textile leftovers, industrial plastic components, carpeting and, not least, fishnets from the world’s oceans – all composed of nylon – are collected and carefully tested at the laboratory in Ljubljana, Slovenia.
The fishnets are retrieved from all parts of the world – from the North Sea to South Asia – and include so-called ‘ghost nets’, which have been lost and left at sea and pose a serious threat to marine life. The waste is collected through different initiatives and projects, such as The Healthy Seas, where volunteer divers recover nets from the bottom of the European seas, and Net-Works™, which encourages coastal communities in the Philippines and Cameroon to collect and sell discarded fishing nets.
By melting the different kinds of waste materials and ‘un-zipping’ the nylon, they become identical to the material produced by fossil oil. From here, fresh nylon is rebuilt by linking the chains of molecules anew, and then spun to form a textile yarn.
Regeneration means that the material is recycled with perfect quality – retaining nylon’s inherent strength, durability and lightness – and that our new products can be potentially recycled infinitely. The process helps saving crude oil, avoiding CO2 emissions, as well as reclaiming waste materials from the environment. Excess energy from the ECONYL® plant in Ljubljana is used to heat the pools of neighbouring Atlantis, the city’s large water park.
