Textile Lab Bobbin Yarn Dyeing Machine DW202B/DW241B

Bobbin Yarn Dyeing Machine DW202B

Bobbin Yarn Dyeing Machine is specially-designed yarn dyeing machine, it used to dye bobbin yarn under high temperature and high pressure.This package yarn dyeing machine will mixed water and dyestuff evenly in the cylinder before dyeing.The yarn dyeing machinery is common used in the laboratory or factory for sample dyeing.

DW202B/241B Bobbin Yarn Dyeing Machine is specially-designed dyeing machine used to dye bobbin yarn in lab 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 bobbin 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 bobbin 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.

Neither DW201B nor DW241B can dry bobbin yarn in the end of dyeing process, so our QRTC3 Centrifugal Water Extractor and MF-3 Bobbin Yarn Drying Machine are essential if customer need to dry bobbin yarn after dyeing. Please refer to the corresponding parts later in the brochure for more information.

Before dyeing, if the bobbin yarn is purchased from market, customer must use loose winding machine to wind the yarn. After the yarn become loose, it can be used for dyeing; after dyeing, if customer want to sell the bobbin yarn to market, tight winding machine must be used to make the bobbin yarn tight, then it can be sold to market. Our DW7060H Lab Cone Winding Machine is essential if customer need to wind the yarn.

l  Surface treatment: Stainless steel construction with sand blasting surface treatment; inner surface of dyeing cylinder use acid etching treatment to protect cylinder against dyes;

l  Free control of dye liquor flow: The bobbin yarn is placed on the mandril in the dyeing cylinder. The dye liquor can flow out and back from the holes in the mandril. Internal flow and external flow can be switched freely inside the dyeing cylinder according to the dyeing process.

l  High automation: Dyeing process can be controlled manually or automatically. The temperature and water level in dyeing cylinder can be preset by dyeing computer. Real-time pressure in dyeing cylinder is indicated by pressure gauge;

l  High-temperature protection: Opening the lid of cylinder is not allowed when the temperature in dyeing cylinder reaches the preset temperature, such as 85℃.

l  Water-level protection: The service cylinder of DW241B is equipped with water level sensor to prevent water level exceeding the preset water level, such as high level;

l  Lock protection:The bobbin yarn dyeing machine has special cylinder lock can fix the lid of dyeing cylinder to prevent moving in the dyeingprocess.

l  Optional heating methods: With rich experience in lab design, dyeing machines with steam heating functionare normally suitable for dyeing mills, because they have the ability to provide steam source to heat the dye liquor; as for university, institute, etc, we can provide dyeing machine with electrical heating function.

We’ve supplied many customers, among which some have the daily capacity up to more than 100 tons. We have very good experience to offer installation, commissioning & training in customer's factory. Dyeing specialists are available as per buyer request.
