Abstract (en)

[origin: DE19746635A1] A process for the production of modified polypropylene yarn which can be dyed from aqueous dye solutions comprises mixing controlled-rheology polypropylene (CR-PP) which is suitable for fiber production with a reaction partner which can react with the CR-PP and then processing the mixture by extrusion spinning. Independent claims are also included for (a) polypropylene yarn obtained by this process; (b) a process for dyeing this yarn, or textile sheet made from the yarn, with conventional dyes by a standard extraction process from aqueous dye solutions.
