Air dyeing machine
Compared with the traditional spillage dyeing machine, it has obvious function of energy saving and emission reduction, and it basically covers the range of fabric types adapted to the traditional spillage dyeing machine. Some new fabrics, such as Lycoell and ultrafine, have a common dyeing personality. In addition, some of the structure features of the air flow dyeing machine provide very favorable conditions for the uniform dyeing of the fabric. In addition, some leading control skills of the equipment are guaranteed, so that the "one-time success rate" of its dyeing is above 98%, which greatly saves the energy waste caused by rework and improves the production power.
Airflow dyeing is still attributed to the exhaustion process, which is the same with other intermittent dyeing intentions. It is to establish a condition that the dye can be evenly dyed and fixed on the fiber, ensuring that the dyed fabric can finish the dyeing process according to the required color and fastness. Because the structure characteristics and operation process of air flow dyeing machine are different from that of general overflow or eruption dyeing machine, understanding and mastering these basic features can provide assistance and guidance for equipment structure design, dyeing process development and process control.
Working principle of air flow dyeing machine
The airflow dyeing machine adopts the aerodynamics principle, and USES circulating air instead of water to drag the dyed fabric to make circular movement. Therefore, compared with the traditional spillage dyeing machine, the dyeing bath ratio decreases greatly. There are two ways of communication between fabric and dye in air dyeing machine: one is air atomization and the other is air pressure penetration. Air spray atomization means that the dye is firstly atomized through a special nozzle and dispersed in the air stream, and then the air stream with the spray dye is communicated with the dyed fabric and leads the fabric circulation. In the process of communication, the atomized dye not only has a large touching area to the fabric, but also has a strong permeation capacity to the fabric fiber, and speeds up the dispersion speed of the dye into the fiber. The nozzle of the German THEN airflow dyeing machine is chosen this way. The way of air pressure penetration is to choose two nozzles, namely a pure air nozzle and a liquid flow nozzle. Before the fabric being dyed, the liquid flow nozzle is first communicated with the dye through the nozzle, and then enters the air flow nozzle through the cloth lifting roller. The air flow is used to conduct pressure penetration of the dye dew fabric, and the dispersion speed of the dye to the fabric is accelerated in the process of traction fabric circulation. The nozzle of the German Thies air dyeing machine was chosen in this way. From the present application situation, the air flow atomizing dyeing machine is mostly, and has a better application effect. This article is also commented on by the airflow dyeing machine with this nozzle mode.
