AB - PRODUCTION AND USE OF NEW RANGES OF MAN-MADE FIBRES UTILIZATION OF THE WASTE FROM THE PRODUCTION OF POLYESTER FILAMENT YARN AND STAPLE FIBRE A. A. Petrov and E. M. Aizenshtein UDC 677.494.674.004.82 World production of polyester fibre and yarn reached 3,391,000 tons in 1975 after an average annual in- crease of 15.6% and continues to rise at a rapid rate [1]. The utilization of the 5-10% waste produced in the synthesis of the polyethylene terephthnlate (PETI~ and in its processing to filament yarn and staple fibre rep- resents a serious economic and technical problem when its solution is based in the conventional approach. At the present prices for polyester waste from the production of yarn and staple fibre the net cost of regenerated dimethyl terephthalate (DMT) is 2.4 times higher than that of the original starting material [2]. According to tentative calculations the recycling of regenerated monomers into the production of polyester staple increases the outlay on starting materials. When account is taken, moreover, also of losses and of the lower equipment productivity and intermediate-product quality, then the DMT recovery costs the Plant about five times more than the synthesis of the fresh product. Measures aimed at improving the
