Temperature control atomization yarn dyeing process and system thereof

Abstract

The invention discloses a single yarn dyeing process and system. The system comprises an unwinding mechanism, a guide roller mechanism, a wetting mechanism, a spray dyeing mechanism, a drying mechanism and a winding and rewinding mechanism. Dyeing steps comprise procedures of yarn rewinding and unwinding, yarn humidity adjusting, yarn dyeing, drying, yarn rewinding and forming, and the like, wherein in a dyeing process, a temperature control high-frequency atomization dyeing process is adopted, dyeing effects of more efficiency and more stable chromaticity can be achieved by adjusting atomization chamber temperature and atomization chamber humidity during dyeing, and a dyeing effect of more evenness can be achieved by adjusting yarn humidity before dyeing. By adopting the dyeing process and system, the dyeing course is simple, dyeing permeation is even, the course is continuous, the operation is simple, the yield is high, water consumption and sewage drainage are less, energy consumption is low, loss is less, and economic benefit can be greatly improved.

Description

technical field [0001] The invention relates to a single yarn dyeing process and system, in particular to an atomization dyeing process and a dyeing system. Background technique [0002] The development of today's international textile printing and dyeing industry is based on resources, environment and health; the printing and dyeing industry is also actively developing new printing and dyeing processes that are conducive to energy saving, emission reduction and clean production. The traditional textile printing and dyeing uses dyes, chemical auxiliaries and water as the main media, through several major steps of reversing, dyeing, drying and reversing. Dyeing and other processes. These dyeing steps and processes have obvious shortcomings: (1) The dyeing process needs to repeat the yarn rewinding. The dyeing process yarn passes through a high-temperature dyeing vat, long-term dyeing, dehydration drying and other processes. There are many processes, large water consumption, ...

AI Technical Summary

Problems solved by technology

However, these dyeing steps and processes have obvious disadvantages: (1) the dyeing process requires repeated yarn rewinding. During the dyeing process, the yarn passes through high-temperature dyeing vats, long-term dip-dyeing, dehydration and drying processes. There are many processes, large water consumption, high energy consumption, Large pollution and high power consumption; (2) Before dyeing, the yarn is scoured or pre-treated to improve the hydrophilicity and capillary effect of the yarn, but the pre-treatment process also consumes a lot of water, High energy consumption, at the same time, additives such as surfactants are used in the pretreatment process, making it difficult to treat wastewater

[0004] The above-mentioned existing technologies are mainly based on different process requirements, and the dyeing process is continuously improved, but the process used is still mostly the dip dyeing process, which still produces more sewage, more processes, higher energy consumption, and high production costs.
