SOME POPULAR TYPES AND ADVANTAGES/DISADVANTAGES
♣Direct fabric dyeing technology: It has been widely and widely used in the textile dyeing industry from a long time ago.Direct dye woven fabric dyeing technology satisfies the majority of mass fabric items, with no high requirements for high quality of color fastness.
♦Some advantages of this technology such as:
- The cost of dye is low.
- Pretreatment and dyeing time are not too long.
- The time color chemicals soak into the fabric surface faster
♦This dyeing technology has some disadvantages as follows:
- Low fastness to light color and dry, wet friction.
- The extraction rate of chemicals is not high, leading to more difficulties in the wastewater treatment process.
♣Activated fabric dyeing technology: is a more advanced dyeing technology than direct dyeing technology. With direct dyeing technology, some shades of color cannot be dyed, but reactive dyeing technology can guarantee them due to the specific characteristics of the drug and the different process.
♦ This technology has the following advantages:
- Good color fastness.
- Bright colors can be dyed.
♦Reactive dyeing technology has the following disadvantages:
- Pre-treatment and chemical costs are high, especially with some colors such as blue, green E.
- Longer dyeing time.
