In order to better show a post-dyeing drying and shaping system for yarns, the embodiment now provides a post-dyeing drying and shaping process for yarns, which comprises the following steps:
step one: after the yarn is dyed in the dyeing pool 1, the yarn is conveyed by a conveying roller 11, and then the yarn is conveyed into the drying box 2 through a material guide opening 3 and a guide roller 4 for drying treatment;
step two: the interior of the drying box 2 is divided into a first cold air chamber 21, a hot air chamber 22 and a second cold air chamber 23, so that the yarn can be subjected to air cooling preliminary dehydration, then heating and drying, and finally air cooling and cooling operation treatment;
step three: when the yarn is subjected to preliminary air-cooling dehydration and enters the hot air chamber 22 for drying treatment, accumulated water on the surface of the yarn is evaporated to generate hot steam during drying, and the suction fan 62 can rotate to generate negative pressure to adsorb the hot steam in the hot air chamber 22;
step four: the hot steam absorbed into the gas cylinder 6 is conveyed into the condensation pipe 71 through the gas pipe 7 to be condensed, so that the hot steam is changed into water again and finally discharged into the dye-printing pool 1 again;
step five: when the yarn is dehydrated and cooled by air cooling in the first cold air chamber 21 and the second cold air chamber 23, accumulated water blown off on the yarn falls into the water collecting plate 5 through the water leakage holes 24 to be collected.
