The dyeing lab is an organization that conducts dyeing tests. Before the dyeing factory conducts mass production, it is necessary to carry out dyeing tests in the dyeing lab with dyeing lab machine to make the dyeing results more perfect. Then let’s take a look at what types of instruments are in the dyeing lab.
Types of dyeing lab machine
Dyeing lab machine can be divided into fiber dyeing machine, yarn dyeing machine and fabric dyeing machine according to different dyeing products; According to the different temperature and pressure required for dyeing, it can be divided into normal temperature and pressure dyeing machine and HTHP dyeing machine. According to different dyeing methods, it can be divided into intermittent dip-dyeing machine and continuous pad dyeing machine.
In this paper, the dyeing lab machine is classified according to the different temperature and pressure. The commonly used dyeing machine includes IR dyeing machine, winch dyeing machine, jigger dyeing machine , garments dyeing machine and so on.
HTHP Dyeing Machine

DW202B/241B Series Package Dyeing Machine is specially-designed dyeing machine used to dye package yarn under high temperature and high pressure. What’s more, DW241B is equipped with dye stuff auxiliary supplying system, so suitable for dyeing cotton yarn as well as polyester yarn, wool yarn, etc. DW202B has one dyeing cylinder. Water and dyestuff are added into the cylinder firstly and mixed evenly. Then place the package yarn into the cylinder. After the heating tube starts working, the temperature and pressure in the cylinder will rise and then the bobbin yarn can be dyed effectively in an environment of high temperature and high pressure.
DW241B has an extra service cylinder, connected to the main cylinder. Water and dyestuff are added into the service cylinder and mixed evenly while package yarn is placed in the main cylinder. The mixed dye liquor can be injected into the main cylinder. In the process of dyeing, user can add dye liquor through the service cylinder, no need to open the main cylinder repeatedly, improving efficiency and safety.
|Capacity||1, 3, 5, 12, 25, 35, 56, 108, 162, 216kg|
|Heating rate||From 20oC to 130oC (20min)|
|Cooling rate||From 130oC to 80oC (25min)|
|Cooling liquid pressure||0.3Mpa, 5~10℃|
|Heating method||Steam heating or electrical heating (please specify before placing order)|
|Power supply||AC380V 50Hz|
HS Series HTHP Dyeing Lab Machine is a universal laboratory dyeing apparatus for formulation of production recipes. It is applicable to dye knitted fabric, woven fabric, yarn, loose fibers or zipper. It has a single dyeing bath with hinged lid and magnetic-valve-controlled water cooling coil and a washing sink.
|Max. dyeing temperature||135°C|
