Description

Technical Field

[0001] The utility model relates to the technical field of filament shrinkage test, in particular to a full-automatic shrinkage tester. Background Art

[0002] Filament, also known as continuous filament, is a type of chemical fiber. Filament is a continuous long thread. In the chemical fiber manufacturing process, the spinning fluid is continuously extruded from the spinneret, cooled by air or solidified into filaments in a coagulation bath to become continuous filaments, and then subjected to post-processing steps such as stretching, twisting, or deformation for further processing and application. In the production of filament, its shrinkage rate needs to be tested.

[0003] The patent with the prior art application number 202221448230.0 discloses a filament shrinkage tester, including a tester body, and heating components, yarn storage racks and heat dissipation components are respectively provided on both sides and the inner side of the tester body. The heating component supplies hot gas to the yarn storage rack, and the heat dissipation component includes a mounting groove, a liquid storage box, a water-absorbing cotton board and a connecting pipe. During the use of this scheme, when it is necessary to discharge the hot air, since the liquid storage box is provided with low-temperature water inside, the water-absorbing cotton board is soaked with low-temperature water, that is, when the hot air flows out to the outside through the water-absorbing cotton board, heat exchange is performed at the water-absorbing cotton board, so that the temperature of the hot air drops. Finally, the hot air after the temperature drops is discharged through the exhaust fan, thereby achieving the effect of cooling the discharged hot air when the tester is in use, that is, avoiding the phenomenon that the hot air causes burns or other discomfort to outsiders.

[0004] In the above application, the hook used for hanging the filament is too small and sharp in shape, which is not only inconvenient for the staff to hang the filament, but also may cause the staff's hands to be stabbed by the hook when hanging the filament. Utility Model Content
