How does a dyeing machine work?
In jet dyeing machines a strong jet of dye liquor is pumped out from an annular ring through which a rope of fabric passes in a tube called a venturi. This venturi tube has a constriction, so the force of the dye liquor passing through it pulls the fabric with it from the front to the back of the machine.
Which solvent is used for solvent dyeing?
Solvent dyes come in red, yellow, blue, and green colors. A characteristic physical property of a solvent dye, like we said above, is solubility in an organic solvent. Some of the typical solvents are alcohols, ethers, ketones, aliphatic and aromatic hydrocarbons, oils, fats, waxes, and chlorinated hydrocarbons.
Which machine is used for dyeing?
Jigger dyeing machine: This machine use to dye woven fabric. Winch dyeing machine: In this machine both woven and knitted fabrics are dyed. Specially knit dyeing is done by this machine. Jet dyeing machine: Knitted and woven fabric can be dyed by this machine.
What is continuous dyeing?
The continuous dyeing is a two-stage operation which involves continuous preparation and continuous dye application and fixation which means instantaneous physical application of dye by padding.
What is a beam dyeing machine?
The beam dyeing machine operates with the same principle as that of package dyeing machine. It can be effectively used to dye yarn or fabric. The process works like this, fabric or yarn in open width is rolled on to a perforated beam. The beam then subsequently slid into a vessel that is closed and pressurized.
What are the advantages of a beam machine?
The colour impregnates the fabric as the dye liquor is allowed to go on circulating through the perforations in the beam. Usually the beam machines are designed in such a manner so as to hold a single beam or multiple beams in a batch. Able to adjust water level in accordance to fabric volume. Even dyeing and superior dyeing quality.
What is a perforated beam used for?
It can be effectively used to dye yarn or fabric. The process works like this, fabric or yarn in open width is rolled on to a perforated beam. The beam then subsequently slid into a vessel that is closed and pressurized. The colour impregnates the fabric as the dye liquor is allowed to go on circulating through the perforations in the beam.
