Rieter

Recycling of dirty waste

Index

The various processes in the blowroom create various waste materials which cannot be reused for textile purposes, such as:

  • coarse dirt remaining after recycling;
  • fly from the preliminary filters;
  • dust from the fine filters.

Dirty waste consists of a large amount of impurities and a smaller amount of fibers. The latter can be recycled in different recycling plants.

In Rieter installations, for example (see Fig. 79), waste from all blowroom machines and cards is sucked directly through the  UNIclean B 12 cleaner of the recycling equipment (1) to a mixing bale opener (2). The mixing bale opener continuously feeds the cleaned material back into the blowroom line (3). If dirty waste is involved, an additional  UNIflex B 60 cleaner should be inserted between the  mixing bale opener (2) and the point of feed into the blowroom line. This installation can also be operated in off-line mode if the secondary raw material is not re-blended immediately but pressed into bales in a bale press (4).
