Round Tube Dyeing Machine

A: Transport of the dye molecules from solution to the substrate surface. Dye adsorption on the substrate surface. Diffusion or penetration of the dye from the substrate surface to the interior of the fibre through its amorphous regions.

A: Package dyeing is a multi-step process where natural yarn is dyed in a solution at high temperatures. With package dyeing, you have more flexibility for color customization since the lots produced are typically smaller, with a minimum order quantity of 150 lbs per color.

A: Dye solution is sprayed or jet-fed on to the fabric as the fabric passes through the nozzle, which is the main place that dye solution exchanges with fabric in terms of dye exhaustion. During repeated fabric circulation inside the machine, a dyeing process is carried out.

A: A Continuous dyeing process typically consists the following. Dye application, dye fixation with heat or chemicals and finally washing. Continuous dyeing has been found to be most suitable for woven fabrics. Mostly continuous dye ranges are designed for dyeing blends of polyester and cotton.

A: First, a substrate is placed in a medium, most often water, to which dyestuffs and auxiliary chemicals have been added. Dyes are then adsorbed to the surface of the substrate and slowly diffuse into the fiber. Once inside the fiber, dyes migrate (or level out) and are then fixed to the fiber.

A: Batch dyeing (exhaust dyeing) is a method of dyeing a textile material. The method involves the gradual transfer of dye from a dye bath to the textile material in the same piece of equipment. The various methods of batch dyeing result from the type of machine used in the dyeing process.

A: Top dyeing is a method of dyeing fiber or yarn prior to being spun. In this method, the short fibers are removed before the dyeing process. Top refers to the long fibers of wool from which the short ones were removed and used for worsted yarn.
