This yarn could harvest water from fog
Water scarcity is becoming a critical problem, especially in remote regions with limited access to water. Traditional methods of collecting water from the atmosphere are often inefficient due to high energy requirements or slow release rates.
To address these issues, there is an urgent need for materials that can improve the efficiency of water harvesting systems. Happily, nature provides inspiration through organisms that have evolved efficient water-collection techniques.
How has technology helped create this yarn?
Inspired by nature, researchers have created a yarn designed to capture water from fog! This offers a new approach to addressing water shortages in dry regions.
By mimicking the alternating hydrophilic and hydrophobic structures found in desert beetles and the water-capturing properties of spider silk, this dual-strand yarn speeds up droplet formation and collection. This technology presents a solution for mitigating the world water crisis in areas facing water scarcity.
What is the yarn made from?
Inspired by the water-collecting capabilities of desert beetles and spider silk, scientists developed the yarn using advanced twisting and electrospinning methods to maximise fog collection. The yarn, constructed from a combination of hydrophilic polyacrylonitrile (PAN) and hydrophobic polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) nanofibers, offers a solution to sustainable water sourcing.
By alternating hydrophilic and hydrophobic sections, the yarn mimics the amazingly efficient water-harvesting structures found in nature. This addresses the need in some regions for eco-friendly water collection technologies.
How many yarn types exist?
There are natural fibre yarns like wool, cotton, silk, alpaca, cashmere, linen and bamboo. There are also synthetic fibre yarns like acrylic, nylon, polyester and viscose. If you want to purchase some chunky yarn, you can create some cosy knits for winter. Choose your chunky yarn from Wool Couture and be inspired to make something creative.
What can I make with yarn?
From toy stuffed animals, blankets and wall hangings to sweaters and scarves, the opportunities are endless. These items can be made by both beginners and more advanced crafters.
