Abstract
A method for producing at least one crimped multifilament synthetic yarn through the use of a texturing process, wherein a stream of heated gaseous medium is brought into a texturing channel (1), (2), (3), wherein synthetic filaments (4), (5), (6) are displaced and deformed by the heated gaseous medium in the texturing channel (1), (2), (3), wherein both the temperature and the flow rate of the gaseous medium are measured, and wherein the heat flow is regulated. To this end, the device comprises a regulating device (50) and, for each texturing channel (1), (2), (3), at least one temperature sensor (60), (61), (62) and a flow sensor (57), (58), (59).

Method for producing at least one crimped multifilament synthetic yarn through the use of a texturing process, comprising:
- bringing a stream of heated gaseous medium into a texturing channel,
- displacing and deforming a number of synthetic filaments by the heated gaseous medium in the texturing channel,
- and fixing the deformed filaments, so that a crimped synthetic yarn is obtained,
- wherein both temperature and flow rate of the gaseous medium are measured, and a heat supply per unit of time that results by introduction of the gaseous medium is regulated to achieve or maintain a predetermined target value for the heat supply by adjustment or regulation of at least one parameter which influences the heat supply.
Method for producing at least one crimped multifilament synthetic yarn through the use of a texturing process, comprising:
- bringing a stream of heated gaseous medium into a texturing channel;
- measuring both temperature and flow rate of the gaseous medium;
- regulating a heat supply per unit of time that depends on both the temperature and the flow rate of the gaseous medium, the regulating comprising determining a target value for the heat supply and, based on the measured temperature and the measured flow rate, adjusting or regulating at least one of the temperature and the flow rate so as to achieve or maintain the target value;
- displacing and deforming a number of synthetic filaments by the heated gaseous medium in the texturing channel;
- and
- fixing the deformed filaments, so that a crimped synthetic yarn is obtained.
