The preparation of chemical fibers requires the extrusion of a spinneret (plate) into a liquid stream to solidify the fibers, and the temperature control determines the tensile strength and other properties of the fibers. Therefore, researching the silk making process and improving the spinning process can effectively improve the quality of the fiber. The small target and rapid movement of the fiber body make the temperature detection a big problem. This paper mainly introduces the case of using the master selection series thermal imager in the chemical fiber making.
This picture is taken for the TiX1000+ macro lens 3, which is the detection of the temperature of the wire during the spinning process. The shape and thickness of the wire are different due to the condensation of the liquid at the spinneret.
Detection case analysis:
A university textile college studies the process of chemical fiber preparation. The spinning capillary is energized, and the spinning solution sprays the filament through the nozzle to the grounded metal plate. It is necessary to detect and analyze the temperature distribution of the wire from the nozzle to the metal plate at a distance of about 3-4 cm, in order to improve the quality of the chemical fiber. Provide technical improvement basis.
Difficulties in testing:
1. The diameter of the chemical fiber is only a few tens of microns, the target is very small, and the temperature distribution of each wire cannot be seen.
2. It is impossible to shoot at close range due to power-on, and the detection distance is far.
On-site inspection program:
1. Because the silk is very fine, and the temperature difference on the wire is small, use the grayscale palette for focusing;
2. Use TiX1000+ Macro 3 to shoot at a position of about 10cm, supplemented by a two-dimensional adjustable precision displacement head.
3. This solution can distinguish the target of 35μm, and can analyze the temperature of each silk.
