GLEANING THE TARRY MATTER BY TRIETHYLENF GLYCOL IN TUBINGS AT THE MELT SPINNING OF POLYESTER FILAMENTS |
| |
| Abstract: | The cleaning of tarry matter in the melt feed lines for spinning of polyester filaments is introdu-ced in four different methods:that is the solvation, ignition, replacement and welding of tubings. The procedure of cleaning by triethylene glycol and its safty measures are described in detail, it is conc-luded that the solvent cleaning is the most economic, practical, reliable and effective way. |
