The invention relates to a method and a device for separating at least 50% by weight of oil-like preparation agents from preparation-containing elastane fibers based on 100% by weight of the starting agent content in the elastane starting material, in which a mixture of elastane fibers with different titers is used as a fiber cut, whereby one assumes fibers with a titer of 11 to 10,000 dtex and more, the elastane cut fibers are mixed in a mixing container with water in a liquor ratio of water / elastane cut fibers of at least 5/1, the mixing using stirring tools (3) with a Performs speed of at least 1500 1 / min, carries out the treatment at room temperature or elevated temperature, in particular up to 90 ° C, maintains a treatment time of 10 to 60 minutes and then separates the water liquor containing the preparation from the fiber material. |
