From mixed rags to uniform, high-value raw materials

In the current linear economy, huge amounts of valuable fabric are simply discarded as waste or down-cycled during textile recycling processes. This wasteful practice can be radically changed by Fibersort. This innovative technology automatically sorts mixed garments into homogeneous categories of up-front specified fiber types. Fibersort is an optical sorting technology based on Near Infrared Spectroscopy. The technique is sensitive to the molecular absorptions of organic constituents in the near infrared part of the spectrum. Since all clothes have organic constituents, there is no limit to the types of fabric that can be recognized and sorted into uniform categories of fibers with specified compositions, colors and/or structures.

Fibersort is one of a kind

Fibersort is a semi-automatic device that requires a feed of non-assembled garments in a sequence of one piece at a time. The supply of the garments to the system must therefore be done manually. After separating assembled garments like coats and jackets, an operator takes the singular items from a pile and puts them piece by piece on a conveyor belt. The device scans the items on the basis of the previously established specifics of the desired categories of fabric and sorts them by means of pressurized air. For instance, when a blue sweater of 60% cotton and 40% polyester has been scanned, the conveyor belt transports it to the right location where it is blown into the bag with garments of the same color and composition.
