METHOD FOR SIMULATING A VISUAL IMAGE OF A THREAD AND/OR A FIBER PRODUCT MADE FROM THE THREAD, AS WELL AS A METHOD AND DEVICE FOR PRODUCING A BCF THREAD

摘要

The invention relates to a method for simulating a visual image of a thread and/or a fiber product made of the thread, and a method and device for producing a multicolored BCF thread. In this method, the simulation is conveyed on the basis of at least one color parameter of a color additive to the thread and by production algorithms, taking into account the planned production of the thread and/or the fiber product, to generate a visual image of the thread and/or the fiber product. In order to allow the entire production chain, from the thread to the fiber product, to be taken into account in the simulation, a color spectrum of the color additive in the form of a granulate, a paste, or a liquid is measured out and added to a base polymer as a color parameter according to the invention. The thread is formed by melt spinning a number of filaments from the polymer melt. During the production of a BCF thread in particular, the simulation of a visual image of the thread and/or a carpet can be linked to the production process in such a way that at least one of the process parameters is selected and/or monitored, depending on the simulation result. Accordingly, a process control unit controlling the mechanisms of the device is linked to a simulation computer for data exchange.
