Waste of melt-spun fibers is recovered by compaction, introduction into a rust spinning machine or a degassing extruder without prior drying, remelting, filtration of the melt, metering this melt into a fresh polymer melt, in particular in a ratio of 1:20 to 1: 2, preferably 1:10 to 1 : 4, intensive mixing of both melts and spinning of the mixture into fibers. |
