Airflow Dyeing Machine Overview

Author:QINSUN Released in:2023-07 Click:101

Air jet drying is a modern drying process that features low liquor percentage, lower energy consumption and less pollution, and is recognized as an environmentally friendly drying method in the 21st century. The properties and mechanisms of airflow dyeing This article will discuss machines for dyeing and airflow dyeing and a comparative comparison.

As we all know, the of theFabric produced by overflow drying machine has a good hand feel and high fastness, and the ability to adjust to small amount, quickly changing variety, compact equipment area and low investment. In today\'s printing and dyeing works, it has always been the most important dyeing equipment.

Since the late 1980s, with increasing importance to be highlighted environmental problems and the development trend that the fabric quality is becoming more and more high-quality, conventional overflow dyeing machines have gradually after many problems uncovered, such as B. a large bath ratio, high energy consumption, large sewage disposal and fabric pollution. Defects such as low speed. In particular, the problem of environmental pollution is a damage to the ecological environment. The airflow drying machine came into existence.

Mechanism principle of airflow drying machine

In airflow drying, the ideaUtilizing the aerodynamics, the high-speed airflow is generated by the high-pressure fan through the special nozzle to make the cloth run. At the same time, the dyeing liquor is sprayed onto the cloth in mist form, enabling the dyeing. The liquor and fabric come into full contact in a very short time, thus achieving the goal of uniformity dyeing.

Unlike the overflow dyeing machine, water becomes simply as the means of transportation Used for Dyeing Components The cloth is propelled by a high speed air stream. Therefore, its liquor ratio can be quite low. Secondly, the circumstances for the absorption of the dye liquid vary. The cloth absorbs the dyebath from the dyeing liquor spread on the fabric surface and not from the dyeing liquor surrounding the fabric.

Structure of Airflow Dyeing Machine

Fans, circulating pumps, nozzles, dyeing tanks, cloth lifting rollers, cloth discharge rollers, and airflow and liquid e.gCirculation tubes are the key components of an airflow drying system.

The nozzle is the most important component and is responsible for the formation of high-velocity airflow and the atomization effect of dyes and chemicals. The two nozzle types are round and square. The round nozzle is ideal for processing micronsThe nozzle is ideal for processing heavy fabrics and ropes that can be easily rotated.

Features of Airflow Drying MachineShort drying cycle and high efficiency

The heating rate may vary due to the small liquor ratio and the high heat exchange efficiency can reach 8-10 °C min, which significantly shortens the heating time from room temperature to 90 °C. Secondly, the dye liquor circulation is fast, the Stoff speed is high, the fabric can be replaced with the dyeing liquor many times in a short time, and the color can be quickly absorbed under full-dyeing conditions.

Fully washed

Despite the fact that the liquor ratio is the same in airflow dyeing, through the continuous Washing technology, water is sprayed into the cloth through a nozzle system. And, depending on the process requirements, the ejector pump in the blasting system can immediately generate a 60-80°C hot water bath, thus achieving an excellent cleaning effect.

The dyeing quality is reliable and reproducible. After being atomized by the air flow, the dye is atomized. The liquid is sprayed directly onto the fabric surface, with great penetration and a large and homogeneous contact area. The fabric lifting roller is only for reversing the fabric, and the airflow is the power source of the fabric. This means that even at high speeds, the fabric does not generatea lot of tension. When dyeing light and thin materials, the airflow density is lower and gentler even at high speeds. As a result, the air dyeing machine does relatively little harm to the fabric. During the liquid flow dyeing process, it is easy to generate a lot of foam, especially at half-full. Therefore, a defoamer must be applied. Because the cloth is enveloped by an air-water mixing environment when dyeing with liquid flow, no foam is generated.

Eliminate the phenomenon of fabric blocking and knotting.

Many overflow dyeing machines now feature a pivoting component to improve fabric stacking in the cross tank direction. The airflow drying machine not only includes rocking device, but also there is no dye bath in the tank. The substance moves along in the tank due to its own weightner very smooth surface, and the relative displacement between the garments is negligible. This substantially restrains the accumulation state of fabric falling from the fabric guide tube and prevents the fabric from knotting in the tank.

Unlike the overflow drying machine, the fabric take-up roll of the air drying machine is not the primary power source for mass transport. This eliminates hindrances due to a discrepancy between the linear speed of the fabric lifting roller and the airflow speed of the nozzle.

Adaptation to a wide range of fabrics

Airflow dyeing can be used on all fabrics that can be dyed with standard overflow dyeing . Secondly, it has good dyeing ability for various high-quality materials such as tencel fiber fabrics, artificial peach skin and imitation suede fabrics, and the hand feeling is excellent.

With a majoritywake-up function

The current trend in the development of dyeing machines is to realize the multi-purpose function of a single machine. Every user wants to get the most powerful equipment for the least amount of money. In this regard, by adding various attachments with their own specific characteristics, the airflow dyeing machine can be utilized for various applications. For example, adding an air heater, steam-water separator, and a few more tubes to an excellent loose Dr. lead By adding a fabric softener and adjusting the amount of air accordingly, the cloth becomes softer.


With its brand new concept and distinctive performance, the 21st century green and environmentally friendly airflow drying machine has better coped with the difficulties, that existed with the overflow dyeing machine. And by expanding their own akfunctional functions and the addition of certain accessories, it fulfills the multipurpose function of a machine, which is a machine with a lot of development potential.
