Color fastness to washing means, A specimen of the textile, in contact with one or two specified adjacent fabrics, is mechanically agitated under described conditions of time and temperature in a soap solution, then rinsed and dried.
There are two main test methods for testing the colorfastness to washing . of course ,different test methods define different test requirements.please test as following test procedure :
Washing Fastness Test :ISO method
Sample preparation for ISO method:
-A 10x4 sample size is taken and stitched with a 10x4 multifibre from all sides.Multifibre consists of six fibres i.e., acetate, cotton, nylon, polyester, acrylic and wool.
Test Procedure for ISO method:
-25 silver balls were taken, along with the sample and put into the stainless steel container of Rotawash which is rotated for 30 min at 50°c.
-After 30 min sample is dried in 45°c-60°c.
-Then finally mounting is done.
Washing Fastness Test :AATCC method
Sample preparation for AATCC method:
-A 5x15 sample size is taken and stitched with a 6x6 multifibre from all sides.Multifibre consists of six fibres i.e., acetate, cotton, nylon, polyester, acrylic and wool.
Test Procedure for AATCC method:
-50 silver balls were taken, along with the sample and put into the stainless steel container of Rotawash which is rotated for 40 min at 50°c.
-After 30 min sample is dried in 45°c-60°c.
-Then finally mounting is done.
