    摘要: A method of manufacturing bulked continuous carpet filament which, in various embodiments, comprises: (A) grinding recycled PET bottles into a group of flakes; (B) washing the flakes; (C) identifying and removing impurities, including impure flakes, from the group of flakes; (D) passing the group of flakes through an expanded surface area extruder while maintaining a pressure within the expanded surface area extruder below about 25 millibars; (E) passing the resulting polymer melt through at least one filter having a micron rating of less than about 50 microns; and (F) forming the recycled polymer into bulked continuous carpet filament that consists essentially of recycled PET.

    摘要: The instant invention is concerned with the post-treatment of ²-hemihydrate plasters for the purpose of stabilization. The invention relies in the addition of a retardant to the calcined ²-hemihydrate. It is also the purpose of the invention to provide stabilized ²-hemihydrate plasters which exhibit advantageous properties.
