METHOD FOR TREATING TEXTILE WASTE CONTAINING THERMOPLASTIC FIBRES

摘要

The invention concerns a the treatment of textiles containing thermoplastic fibres in a proportion of 8 to 98 % by weight. Said textiles are disintegrated by dry process. The disintegrated particles should have the following dimension: at least 90 wt. % should have a maximum length of 30 mm and at least 10 wt. % of them should have a length exceeding 10 mm. The method consists in reacting the resulting disintegrated textiles with 3 to 30 wt. % (with respect to the textile weight) of molten thermoplastic polymer waste and adding further 3 to 60 wt. % (with respect to the textile/polymer waste mixture) flue ash and/or microslag with particle size of 0.1 to 3 mm. The resulting mass is homogenised by mixing with constant heat supply adjusted such that the resulting mass preserves its viscous state. This process lasts about 10 to 60 minutes. The resulting substance is then optionally compressed while it is still hot at a pressure of 0.5 to 5 MPa's.
