METHOD FOR MELT-SPINNING POLYESTER MICROFILAMENTS HAVING A MAXIMUM DTEX OF 0.7 AND POLYESTER MICROFILAMENTS THAT CAN BE PRODUCED ACCORDING TO THIS METHOD

摘要

The present invention relates to a melt-spinning a polyester micro-filaments having a fineness of 0.7 dtex and up to micro-filaments, which may be prepared accordingly. According to the invention, the emission of micro-filaments from the melt, depending on the fineness having a reduced solution viscosity in comparison to the prior art.
