MELT SPINNING METHOD FOR PRODUCING A COMPOSITE YARN AS WELL AS A COMPOSITE YARN

摘要

The invention relates to a melt spinning method for producing a composite yarn as well as a composite yarn. The production of the composite yarn occurs by two parallel spun filament bundles, with one of the filament bundles being cooled to a POY yarn with a partially oriented molecular structure, and the second filament bundle being cooled to an HOY yarn with a highly oriented molecular structure. The POY yarn and the HOY yarn are jointly withdrawn and combined to the composite yarn. To ensure the physical properties that are required for textile applications, and the desired yarn effects, the invention provides for combining the filaments of the POY yarn and the filaments of the HOY yarn to a mass ratio in the composite yarn of MPOY/MHOY = 2.5, with the filaments of the POY yarn having a denier = 2.0 deniers, and the filament bundles of the HOY yarn having a denier = 4.0, preferably = 1.5 deniers.
