antibacterial, temperature-regulating, tear-resistant and aesthetically pleasing. Its versatility makes it irreplaceable in both fashion and medicine. However, products made from this precious material, which is laboriously produced by silkworm spinners, often only have a short lifespan. This is where the Air Silk concept comes in, which enables the sustainable reuse of used silk textiles. The discarded silk fibre is roughened and shortened by soaking it in a special alkaline solution, creating a silk pulp. This pulp can then be moulded over a three-dimensional ceramic filter element using fibre casting. The result is a unique filter system that purifies the room air with a delicately shiny top layer of silk fleece. Thanks to the antibacterial properties of silk, this system not only acts as a passive filter, but also actively contributes to improve the air quality.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-table alignright is-style-regular\"><table><tbody><tr><td class=\"has-text-align-left\" data-align=\"left\">student:<\/td><td>Emil Frederking<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">project:<br><br><\/td><td><a href=\"https:\/\/www.burg-halle.de\/gast\/projects\/the-insect-project-resilience-part-i\/\" data-type=\"page\" data-id=\"8738\">The Insect Project <\/a><br><a href=\"https:\/\/www.burg-halle.de\/gast\/projects\/the-insect-project-resilience-part-i\/\" data-type=\"page\" data-id=\"8738\">\u2013 Resilience Part I<br><\/a><\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">year:<\/td><td>2023\/24<\/td><\/tr><\/tbody><\/table><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:62px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-2 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.34%\">\n<p class=\"subtitle\">With a series of speculative objects, the &#8222;Air Silk&#8220; project poses the question of whether silk functions as an air filter. It was prompted by an exploration of the material silk as a product of the Bombyx Mori silkworm. The material has had a special significance for thousands of years. It is crucial for global trade relations, and the term &#8222;Silk Road&#8220; is still known today. But how is this material handled when it is no longer used for textiles?<br>An alkaline modification can be used to produce a fleece from residual silk. I built on this research work and adapted the process to also utilise used silk textiles. The resulting fleece retains the properties that make silk so valuable: a typical lustre, good moisture absorption and antibacterial qualities.<br>I also focussed on how the recycled nonwoven could be reused in order to ensure that its qualities are made best use of.\u2028New silk in medical contexts is an established practice and an air filter proved to be the optimal application for the recycled nonwoven. The antibacterial properties are particularly important here, and the resulting nonwoven is characterised by good air permeability. The combination of these properties with the typical appearance of silk led to the development of the first and outermost filter stage of the air filter.\u2028The second filter stage consists of a ceramic filter made from a natural sponge soaked in ceramic. After several trials, the loofah cucumber proved to be the optimum solution. The internal hollow chambers and uniform wall thickness allow the air to be filtered to pass through optimally.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.34%\">\n<p class=\"subtitle\">The silk fleece is applied to the ceramic filter in the same way as in fibre shaping processes. The filter is immersed in a bath of silk pulp by a connected suction unit. The silk is deposited in the filter, closes the passages and, after drying, allows air to flow through, filtering out particles. The combination of silk and ceramic filter thus forms the first two filter stages of a conventional filter system.<br>In contrast to conventional air filters, which hide their filter elements, with Air Silk the filter determines the shape of the object. The silk-coated ceramic forms a visible filter that does not need to be concealed.<br>These filters can be used in central filter systems with suction units or as stand-alone, decentralised filters.The latter can be placed where they are needed and are equipped with a fan that can be used on mains or battery power via a USB cable. As filters become saturated with particles over time, they can be cleaned in a water bath.The silk detaches from the ceramic structure and can be reprocessed. The ceramic filter is disinfected with boiling water, then re-coated with silk and reintegrated into the filter system.This method ensures that the filter elements last as long as possible. At the end of their useful life, the filters can be broken down into their component parts. The silk is washed out and composted as a pure protein structure, the ceramic is disposed of separately and the electronics, which are attached to a separate base, can simply be separated and disposed of.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\"><\/div>\n<\/div>\n\n\n\n<div style=\"height:60px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"863\" height=\"1536\" src=\"https:\/\/www.burg-halle.de\/gast\/wp-content\/uploads\/2024\/11\/ENG_Emil-863x1536.jpg\" alt=\"\" class=\"wp-image-9364\" srcset=\"https:\/\/www.burg-halle.de\/gast\/wp-content\/uploads\/2024\/11\/ENG_Emil-863x1536.jpg 863w, https:\/\/www.burg-halle.de\/gast\/wp-content\/uploads\/2024\/11\/ENG_Emil-768x1367.jpg 768w, https:\/\/www.burg-halle.de\/gast\/wp-content\/uploads\/2024\/11\/ENG_Emil-1151x2048.jpg 1151w, https:\/\/www.burg-halle.de\/gast\/wp-content\/uploads\/2024\/11\/ENG_Emil-1568x2791.jpg 1568w, https:\/\/www.burg-halle.de\/gast\/wp-content\/uploads\/2024\/11\/ENG_Emil-scaled.jpg 1438w\" sizes=\"(max-width: 863px) 100vw, 863px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Air Silk recycled silk as ambient air filter Silk is a miracle of nature: it is antibacterial, temperature-regulating, tear-resistant and aesthetically pleasing.
