Fibres & Textiles Latest

Fibres & Textiles Latest innovation from milk Softer, thinner, skin-friendly, antibacterial and 100 % natural nonwovens Sustainable? Of course. But it’s much more than that. QMILK is a unique natural fibre with thermo-bonding properties and probably the world’s smallest CO 2 – footprint that offers exciting opportunities for new nonwoven material combinations. Qmilk is a protein (casein) fibre, comparable to wool and silk and it is the first natural binder fibre for nonwovens. It enhances the natural content and sustainable properties of these materials, and is particularly suitable for use with natural fibres. The fibres are bonded via a thermal bonding process that uses pressure and a relatively low temperature of around 100 °C, which yields benefits in terms of energy savings, as well as production efficiency, while increasing the sustainability of the process. The surface of a nonwoven made with Qmilk has a silky feel and can be embossed. The improved properties of a wool felt product into which Qmilk has been incorporated amply illustrate this effect: the resulting felt is a modern, natural product with a longer life, a distinctive, new silk fabric feel, decreased pilling and increased strength. Moreover, it is also possible to replace the wool content while retaining the wool properties, or to make use of inferior wool fibres without any loss of quality of the final product. Qmilk also fits into the convenience products megatrend, a trend that has generated heightened demand for fibres, and natural fibres, in particular. Qmilk can not only meet this demand, but can also contribute important characteristics in the area of hygiene and medicine, such as the silky-soft feel and skin care characteristics. With its hydrophilic properties, Qmilk is the ideal combination material for wet wipes made from viscose and cellulose. In addition, Qmilk fibre’s natural bactericidal properties make this a environmentally-friendly replacement for silver or other antibacterial agent, while at the same time saving costs. The sustainable aspects of Qmilk go beyond the the products alone: Qmilk fibres not only boast the smallest CO 2 - footprint of all fibres worldwide, consist of 100 % renewable raw materials and are produced in ecological zero waste-processes, but the fabrication of the Qmilkfibre occurs via an equally ecologically beneficial process. To make Qmilk, milk is used that is unfit for consumption and that until now, was disposed of as an expensive, unused by-product. In Germany alone, 2 million tonnes of such non-food milk are discarded every single year. MT Wet wipe Wool-felt product 20 bioplastics MAGAZINE [05/16] Vol. 11

The World‘s No. 1 Trade Fair for Plastics and Rubber 19–26 October, Düsseldorf, Gemany Please visit us at: Hall 8a / G32 Industrial Solutions Polylactide Technology Uhde Inventa Fischer Polycondensation Technologies has expanded its product portfolio to include the innovative state-of-the-art PLAneo ® process for a sustainable polymer. The feedstock for our PLA process is lactic acid, which can be produced from local agricultural products containing starch or sugar. The application range of PLA is similar to that of polymers based on fossil resources as its physical properties can be tailored to meet packaging, textile and other requirements. bioplastics MAGAZINE [05/16] Vol. 11 21
