Abstract: Contrary to packagings or bottles made of pure materials like PET, nonwovens usually consist of a mix of materials and are as such difficult to include in a recycling process. The present invention relates to a method for recycling polyester-based nonwovens comprising 5 to 50% of PET/coPET low melt staple fibers into polyester staple fibers (PSF), and further including these fibers into new nonwovens for a large variety of articles for applications in virtually any technical field.
