Filament cables of denier above 10,000 dtex are produced by operating several continuous melt spinning-stretching processes at production speeds above 3,000 m/min, to form several continuously spun and stretched filament bundles, which bundles are then continuously plied and deposited in the form of a cable. The process among others is useful for high speed production of filament cables of nylon-6 with improved breaking strength and/or breaking extension.

A process for production of cables of filaments of thermoplastic, melt-spun synthetic polymer at a production speed in excess of 2,500 m/min, the cable having more than 10,000 dtex, said process comprising the steps of simultaneously advancing a plurality of melt streams of at least one of said poly
A process for production of cables of filaments of thermoplastic, melt-spun synthetic polymer at a production speed in excess of 2,500 m/min, the cable having more than 10,000 dtex, said process comprising the steps of simultaneously advancing a plurality of melt streams of at least one of said polymers through a corresponding plurality of at least three spinning nozzles, all nozzles lying in the same horizontal plane, each nozzle having the same quantity of 500 to 3,000 spinning dies, directed in the vertical direction downwards for melt spinning 500 to 3,000 filaments from each nozzle; leading said filaments spun from each nozzle in a vertical quenching shaft associated to each nozzle for quenching said filaments by a stream of air; assembling said filaments spun from each nozzle to a bundle of filaments, all bundles having the same amount of filaments and the same denier in the range of 1,000 to 5,000 dtex; while all bundles are running downwards in a vertical direction parallel to each other and in only one common vertical plane, leading each of said bundles to a stretching zone below each quenching shaft consisting of a first and a second godet means to be wrapped around, the peripheral velocity of said first godet means being in excess of 600 m/min, the peripheral velocity of said second godet means being higher than that of said first godet means to stretch each bundle between separate godet means, associated to each bundle by the same stretching ratio to all bundles; heating each of said bundles to a uniform temperature above 40°C. during the stretching; deviating each bundle at a first point below said first and said second godet means to only one second point common to all bundles, lying in said vertical plane at one side of all of said first points to thereby plying said bundles to a cable of at least three bundles, said cable having a denier of more than 10,000 dtex; after stretching, leading each bundle to a shrinking zone, consisting of said second and a third godet means below said quenching shaft, the peripheral velocity of said third godet means being less than the peripheral velocity of said second godet means for shrinkage of the filaments, each bundle being heated in said shrinkage zone to a temperature between 140°and 230°C.; advancing said cable with more than 2,500 m/min by only one common draw-off means; and releasing the tension in said cable and decreasing the axial running speed of said cable to less than 10% of its previous velocity for depositing the cable in a horizontal collection plane in a can which is reciprocating in said horizontal plane.
