Main types and technical characteristics of high temperature and high pressure dyeing machines
May 21, 2018

High-temperature and high-pressure dyeing machines are mainly used for dyeing chemical fiber fabrics and yarn products. At present, there are three types of high-temperature and high-pressure dyeing machines, including high temperature and high pressure beam dyeing machines, winch high temperature and high pressure rope dyeing machines, and high temperature and high pressure overflow dyeing machines.

 

The characteristics of different types of high temperature and high pressure dyeing machines are also different. For example, when the high-temperature and high-pressure beam dyeing machine is in operation, the fabric to be treated is mainly wound on the hollow reel shaft surface covered with small holes, and fed into a horizontal cylindrical stainless steel case, sealed and pressurized and dyed. Processing. The dye liquor is transported by a centrifugal pump, through the shaft, to the fabric layer from the inside out or from outside to inside the cycle. Remember, when operating this type of dyeing machine, be sure to handle it carefully so as not to cause chromatic aberration.

 

The capstan type high temperature and high pressure rope dyeing machine has very good sealing performance and high pressure resistance. It can be used not only under high temperature and high pressure conditions, but also under normal temperature and pressure conditions. This type of high temperature and high pressure dyeing machine is in use. The consumption of steam is small, and the applicable dyes and fabrics are widely used.

 

Another type of high-temperature and high-pressure dyeing machine is called a high-temperature and high-pressure overflow dyeing machine. In operation, the dyeing liquid is mainly extracted from the bottom of the dyeing tank and enters the overflow tank through the heater. There are two or three overflow pipe inlets parallel to the overflow tank.The fabric is circulated by the active guide roller and the overflow of the dye liquor. During the dyeing process, the fabric is in a relaxed state, the tension is small, the dyeing is uniform, the color is bright, and the product has a soft hand. The equipment is mainly used for the dyeing of synthetic fiber warp knitting, weft knitting and elastic fabrics.

 

The high-temperature and high-pressure dyeing machine adopts variable frequency speed regulation during operation, which not only has high running speed but also is very stable. Due to the new structural design of the high-temperature and high-pressure dyeing machine,Therefore, the cloth blank can run at a high speed under a low tension state and is provided with a blank impact point.It can not only ensure the orderly stacking of fabrics in the dyeing tank, but also can avoid the production of dyeing and improve the feel and bulkiness of the fabric.
