The manufacturer of nonwovens machines Oskar Dilo Maschinenfabrik KG, Eberbach/Germany, presents MicroPunch, a complete production line for intensive needling. This will be the first time worldwide that an industrial MicroPunch installation will run with fiber to show the industrial exploitation of Dilo MicroPunch technology for needling fine and lightweight nonwovens to be used in hygiene, medicine, apparel and other applications.
The good abrasion resistance of the intensely needled material suggests further application fields apart from medicine and hygiene, such as apparel, artificial leather, battery separators and filter media. The production of personal care, single use wipes with a weight range between ca. 30 and 60 g/m² made of fine fibers, often with blends of polyester and viscose, has been up to now a domain of hydroentangling technology. As this product is a typical disposable, it is in the focus of sustainability and recyclability. For this reason, biologically degradable fibers are a goal for more environmental sustainability.
Compared to hydroentangling, the MicroPunch needling line allows a reduction of the energy consumption (electricity and gas) of about 75% based on the complete installation. Given recent increases in electricity and gas costs, this reduced consumption has a great impact on the total costs per kg of finished material in some countries, even at the lower production speeds of needling technology. A MicroPunch line consists of Dilo Temafa components for fiber preparation, a Dilo Spinnbau universal or random card and three MicroPunch specialty needlelooms for pre- and finish needling as well as a winding unit.
