Introduction
• The stability of color or its fastness is one of the most important requirements
of valuable customers. Colour fastness of a dyed goods means the resistance
power of a dyed goods against any hazards.
• The color textiles show different resistance power to different agencies such
as light, wash, rubbing, perspiration, water, bleach, acid, alkali etc.
• There are many types of testing of color fastness. But in the industry the
fastness test is done according to the buyer requirement.

• Colorfastness to Washing is a method for determining the
resistance of the colour of textiles from all kinds of wash in water
with soap and detergent. There are different test methods to check
the color fastness to washing which is standardized by ISO.
Test Temp.( ° C) Time (mints) Steel balls Chemicals
ISO-105-CO1 40 30 0 Soap(5 g/l)
ISO-105-CO2 50 45 0 Soap(5 g/l)
ISO-105-CO3 60 30 0 Soap(5g/l) +soda ( 2 g/l)
ISO-105-CO4 95 30 10 Soap(5g/l) +soda ( 2 g/l)

Sample Preparation:
If the textile to be tested in fabric: Cut the sample fabric 10cm ×4 cm and make sure
all colors are included (if necessary use additional specimens) in it. Sew it along all four
edges with the same size of multi fiber fabric. This is the composite test specimen.
If the textile to be tested is yarn or loose fiber: Take a mass of yarn or fiber
approximately equal to ½ of the combined mass of the adjacent fabrics, then place
between a 10cm ×4 cm piece of multi – fiber fabric and a piece of same size non dye
able fabric and sew them along all four sides. This is the composite test specimen.
According to ISO RECOMMENDATION NO3 (ISO 105 C03): The composite specimen is
treated in a wash wheel or an equivalent apparatus at 60 ± 2°C (140±3.6°F) for 30 mints
using the color fastness test detergents 77(ISO Std soap) 5 g/l and 2 g/l soda ash to a
given liquor ratio of 50:1.
• Finally we decreased the temperature and washed with cold water and dry them.

EVALUATION:
 Compare the contrast between the treated and untreated sample with
the changing grey scale and staining of color in the adjacent multi-
fiber fabric with the staining grey scale.
 This assessment is done in a color matching cabinet under standard
lighting of D65 (Artificial day light).

Color Fastness to light
• This test measures the resistance to fading of
dyed textile when exposed to day-light.The test
sample is exposed to light for a certain time(24
hrs, 36 hrs,48 hrs, 72 hrs, etc) or by customer
demand and compare the change with original
unexposed sample.The changes are assessed
by Blue Scales (1-8).
