Abstract: A process for the simultaneous texturizing, i.e. crimping, and dyeing or finishing of thermoplastic yarns comprising packing and compressing the yarns into a confined space through introduction of a flow of a compressed fluid heated to a temperature sufficient to set the yarns, allowing a portion of the compressed fluid to provide movement of the yarns axially in the confined space with the remainder of the fluid escaping laterally from the confined space into further annular space under a pressure lower than the pressure of the confined space, but higher than atmospheric pressure; and simultaneously introducing at least one dyeing solution or finishing agent into the confined space over the compressed yarns, such process being characterized in that the compressed yarn is continuously passed through at least one expansion zone and thereafter through at least one zone in which a further fluid is introduced under pressure. Such process allows for the simultaneous dyeing or finishing of thermoplastic yarns in a high speed texturizing process.
