What Is Azoic Color | Properties of Azoic Color

Azoic Color is produced by the combination of Naphtha or coupling component and Diazo component. Production procedure of Azoic Color is different from other dyes production process. Azoic color is different from other dye and its application process is also different.

Azoic Color is called Ice Color or magic color because it needs low temperature and after coupling color is produced within few seconds. Color fastness properties are good to excellent.

Properties of Azoic Color: Properties of Azoic Color is given below:

  • Azoic Color is a water insoluble dye.
  • Azoic Color is composed of two components; such as
  1. Azoic coupling component
  2. Azoic Diazo component
  • For color production, coupling is necessary.
  • Coupling is done in alkaline condition.
  • Applicable mainly for cellulosic fibers.
  • The time of application is lengthy.
  • Very bright shade can be produced by Azoic Color.
  • A fastness property of the textile material which is dyed by Azoic Color is good to excellent.
  • Azoic Color is comparatively cheap in price.
  • Dyeing process is run by three processes – Naphtholation, Diazotization and Coupling.
  • Final color is produced within few seconds after immersing the textile materials in the dye solution.

Azoic Color is used for coloring small amount of textile materials dyeing. It is suitable for small scale industry. Azoic color dyeing process is not popular as reactive dye or disperses dye dyeing.

So, select your dyes as you need.

Disperse Dyes | Properties Of Disperse Dye

Disperse dyes are synthetic dyes. Disperse dye is one kind of organic substances which is free of ionizing group. Disperse dyes are less soluble in water and used for dyeing synthetic textile materials. Disperse dyes is mainly used for dyeing polyester yarn of fabric. in the other hand, Reactive dyes are used for coloring cotton or cellulosic fiber.

Disperse Dyes | Properties Of Disperse Dye

A question could be appear in your mind that why this dye is called disperse dyes? It has a simple answer. Disperse dye is so called because it is non soluble and molecularly dispersed therefore dispersing agent is necessary for coloration with disperse dyes.

Properties of Disperse Dyes:

  • Disperse dye is one kind of organic substances which is free of ionizing group.
  • Disperse dye is non-soluble in nature.
  • Disperse dye is insoluble in water.
  • Dispersing agent is needed for dyeing with disperse dyes.
  • Fastness properties specially wet and light fastness is good to excellent.
  • Disperse dyes are applied in acidic condition.
  • Disperse dyes are widely used for dyeing synthetic fibers. Polyester fiber is dyed by disperse dyes but nylon, acrylic also can be dyed with this.
  • Disperse dyes dyeing is carried out in high temperature.
  • In some case carrier method is applied for dyeing of polyester with disperse dyes
  • Disperse dyes are economical.
  • Molecular size of disperse dyes are smaller than other dyes.
  • Disperse dyes are derivatives of azo, anthroquinone, nitro and quinine groups.

Disperse dyes dyeing is carried out in high temperature for this reason dyeing machine should have the capability of serving this process.

Different dyes manufacturing companies manufacture disperse dyes. Choose your color brand on which you can trust for better dyeing.

Different Parts Of Computer Color Matching System | CCMS Utilities

Computer color matching system (CCMS) is the latest system to predict and analyze the color of the sample. It is mostly used for wet processing section. I have mentioned about the functions of CCMS in one of my blog. Now I like to present an idea about the different parts of a CCMS or how a CCMS is arranged and functions of different parts.

Computer color matching system was first established in 1963 by ICI dye stuff division for color matching prediction in their lab only for their customers. But CCMS was commercially introduced by International Color System (ICS) in 1973. Now CCMS is developing by different CCMS manufacturing companies. Among all of them DATA COLOR is best in this regards.

Following basic things are considered for CCMS:

  • Spectrophotometer is the main color measurement instrument.
  • Reflectance from a mixture of dyes or pigments applied in a specific way.
  • To judge the closeness of the color matching, optical model of color (CIE Lab/ Hunter Lab/ XYZ Model) is used.

Different parts of computer color matching system: CCMS has different parts by which it runs. Followings are the main parts of CCMS.

  1. Computer: Computer is needed for CCMS. In this system special software is installed in the computer before run the CCMS. Spectrophotometer and printer is joined with the computer. When spectrophotometer analyzes the color the results show in the monitor and if needed results could be print out by the printer. All the information is send from the hard disk of the computer.
  2. Spectrophotometer: Spectrophotometer is the main instrument of CCMS. Spectrophotometer has a sample holder in the middle of the front side. The sample holds on there. Then it takes the reflection of the light and analyzes the depth of the color and shows the results on the computer monitor. It also makes decision about the fastness properties of the sample.
  3. Printer: Printer is joined with the computer for printing the results.

So, computer color matching system is the best way to find out the solution about a sample color. Try to use it in your practical life. If you have better idea let me know.
