Fabric Shade Checking System In Dyeing Floor

Fabric Shade Checking

Shade is a common word in the dyeing, printing, and finishing unit of a textile mill. However, it is the physical testing method of an offline quality control assurance system. I have written about the shade matching system in a dyeing lab or lab dip development procedure in one of my blogs a result that will help you to know about the shade matching system.

Shade matching depends on the accuracy of the man’s eye. It is a visual process for this reason the same shade may have different comments from different people. So, a dyeing expert or color expert is needed for this purpose. Besides the manual shade matching system like the computer color matching system (CCMS) can help man to make decisions about the shade of a specific sample.

Shade Checking:

The shade achieved is to be checked several times while in process and at the finished state to ensure the customer’s demand under a recommended light source. Generally, the shade is checked at the following stage-

  • After dyeing
  • After drying
  • Shade checking after trial for finishing
  • After finishing

Shade Checking Instruments:

The shade of the color varies depending on the light source under which the sample is checked out. For this reason, the buyer gives a specific light source under which the sample will be checked. For this, the following equipment is used-

  • Name: Verivide lightbox
  • Manufacturer: James H. Heal & Company Ltd.
  • Origin: England
Light Source:
  1. D-65 (artificial daylight)
  2. TL-84
  3. F (filament light)
  4. UV (Ultraviolet blue light)

In sum, it is important to understand the color tone. It is also important to know about the color combination by which color will be produced. It should take in mind that, the combination of the dye which is used to match the buyer sample color that combination will be used in bulk production. Otherwise, the tone of the color could be varying.

So, the textile engineer should be careful about the shade matching of a textile product.
