DW202B
FYI
Silver
1PCS
China
APPLICATION:
Polyester Yarn Dyeing Machine DW202B is specially-designed dyeing machine used to dye bobbin 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 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.
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 Cone Winding Machine is essential if customer need to wind the yarn.
FEATURE of Yarn Dyeing Machinery:
1. Surface treatment: Stainless steel construction with sand blasting surface treatment; inner surface of dyeing cylinder use acid etching treatment to protect cylinder against dyes;
2. 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.
3. 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;
