Color Fastness Measurement – Part 2

At the previous post I described about the Definition of Color Fastness, Color Fastness of Textile Materials Factors, Principles of color fastness and useful apparatus plus materials of color fastness measurement.

Now I am telling you the rest part of this post –

Reagents:
1.Reference Detergent.
2.Sodium Carbonate/Soda Ash.
3.Distilled Water (Grade-3)

Test Specimen:
A Textile material (Dyed Goods) sample should be cut at 10 CM into 4 Cm and sew it with same size multifiber fabric. This is the composite test sample.

Test Procedure:
The color fastness procedure I am going to tell you is ISO certified and recommended –
ISO-105-C01: Composite sample is treated in a wash wheel for 30 minutes at 40 plus minus Degree centigrade with 5 Gram/Ltr standard soap.

Evaluation:
Compare the contrast between the treated and untreated sample with Grey scales for changing color of dyed sample and staining of adjacent fabric in a color matching cabinet. Numerical rating for color changing is the shade and staining to adjacent fabric. Number of method used.
Reporting Format of Color fastness measurement:
Color change in shade staining in Acetate – Grade 4.
Color change in shade staining in Cotton – Grade 4.
Color change in shade staining in Polyamide — Grade 4.
Color change in shade staining in Polyester — Grade 4-5.
