specific Embodiment approach

[0042] As a specific embodiment of the present invention, there is a gap between the bottom of the waterproof layer 4 and the bottom of the dyeing cylinder body 1;

[0043] There is a gap between the bottom of the waterproof layer 4 and the bottom of the dyeing cylinder body 1. When water is injected into the dyeing cylinder body 1, the water can fill the outside of the waterproof layer 4, so that the water can fully wrap the waterproof layer 4. When the heating device 3 heats the water, the water can fully heat the dye liquor through the waterproof layer 4, which ensures that the dye liquor is heated evenly and effectively improves the dyeing effect.

[0044] As a specific embodiment of the invention, the inner side wall of the dyeing cylinder body 1 is rotatably connected with more than one guide roller 6, and a plurality of guide rollers 6 all penetrate through the waterproof layer 4 and are rotatably connected with the side wall of the waterproof layer 4, and the ends of the g...

Abstract

The invention belongs to the technical field of dyeing equipment, and particularly relates to dyeing equipment for regenerated polyester yarns, a water-resisting layer is arranged, a heating device is placed in the water-resisting layer, and the water-resisting layer forms a closed environment to heat water, so that the boiling temperature of the water can be increased, and the dyeing effect of the regenerated polyester yarns is improved. Meanwhile, the heated water is used for heating the dye liquor on the other side of the water-resisting layer, it can be guaranteed that the temperature of the dye liquor rises slowly and is controllable in the using process through a water bath method, polyester dyeing is more uniform, meanwhile, used hot water can be drained through a water outlet valve, the hot water is used for washing after dyeing, and after the hot water is drained, the water-saving effect is achieved. Cold water is re-injected from the water outlet valve to help the dyeing vat body to be slowly cooled, so that the dyeing vat body can quickly reach the specified temperature to take out the polyester, and the working efficiency of the dyeing vat is improved.

Description

Technical field [0001] The invention belongs to the technical field of dyeing equipment, in particular to dyeing equipment for regenerated polyester yarns. technical background [0002] Recycled polyester fiber refers to the use of polyester cloth, waste polyester bottle pieces, spinning waste silk, foam materials and pulp blocks as raw materials. The waste bottle pieces are crushed and cleaned, and the mixture of various materials is dried, melted and extruded, spun, wound, bundled, drafted, curled, relaxed and heat-set, and cut to form polyester fibers with different lengths. [0003] Polyester needs a variety of colors in daily use, so it is necessary to dye recycled polyester. However, in traditional recycled polyester dyeing, the dyeing vat directly heats the dye liquor when it is heated, so it is difficult to control the temperature rising speed, which requires manual supervision. Too fast rising will easily lead to uneven dyeing of polyester and increase the rework rate of...
