Guiding device for spandex yarn dyeing

Abstract

The invention relates to the technical field of spandex yarn dyeing, and discloses a guiding device for spandex yarn dyeing. The guiding device comprises a bottom plate, a mounting bracket, a paying-off roller, a mounting plate, stress adjusting mechanisms and a yarn carrying mechanism; the bottom of the mounting bracket is connected with the right side of the top of the bottom plate; and the middles of the front face and the back face of the paying-off roller are connected with the tops of the front face and the back face of the mounting bracket through rotating shafts. The two stress adjusting mechanisms are matched, when spandex yarn is in a relaxed state, by matching with elastic acting force of an telescopic spring and through sliding of a cylinder on a circular sliding column, the whole yarn carrying mechanism moves upwards, and thus the spandex yarn is driven to be in an arch state and then to be in a normal straightening state; and otherwise, a tight state of the spandex yarn can be relieved, thus relaxation stress of the spandex yarn is automatically adjusted in the dyeing and paying-off processes, and the phenomena of derailment and pulling-apart of the yarn are avoided.

Description

technical field [0001] The invention relates to the technical field of spandex yarn dyeing, in particular to a material guide device for spandex yarn dyeing. Background technique [0002] Spandex is the abbreviation of polyurethane fiber, which is a kind of elastic fiber. Spandex is generally composed of multiple filaments, usually 10D / filament, and now there are 15D / thread, or even 20D / thread. The production solution of spinning method DMAC is harmful to the liver of the human body. Generally, 10D / root contains 0.5mg / kg, and if 15D / root contains 0.7mg / kg, it exceeds the standard. When producing spandex yarn, special attention should be paid to coiling tension, count on tube, breaking strength, breaking elongation, forming degree, oil adhesion, elastic recovery rate, etc. These problems directly affect weaving, especially Pay more attention to knitting and producing single jersey. [0003] In the dyeing process of spandex yarn, there are many requirements for the wire of ...

AI Technical Summary

Problems solved by technology

[0003] In the dyeing process of spandex yarn, there are many requirements for the wire of spandex yarn, among which spandex yarn itself has elasticity, so in the process of spandex yarn dyeing, the relaxation stress generated by itself needs to be paid attention to at all times , during the process of unwinding the spandex yarn, its slack will directly cause the yarn to break away from the guide roller, thus affecting the dyeing effect of the yarn, and if it is too tight, the spandex yarn will directly appear in a certain part The phenomenon of tearing off, resulting in the failure of the whole process
