Color Fastness to Chlorinated pool water:

Chlorinated Pool water fastness is getting more importance in Terry Towel industry for swimwear and also for yarn dyeing. This method is designed to evaluate the resistance to Chlorinated Pool Water of any colored textile substrate. Here, the test specimen is treated in diluted Chlorine solution under specified conditions of available chlorine content, time and pH condition.

There are two methods to evaluate the same:

AATCC 162-1997:

In this method, the test specimen is treated with 5 mg/lit. active chlorine at neutral pH for 60 minutes at 21C in tumble wash machine.

ISO 105 /E03

In this method, the test specimen is treated with 20 mg/lit. active chlorine at pH 8.5 for 4 hours at 20±2 C in subdued light.

The rating is given on the basis of change in shade. Grade 5 being the best and 1 being poor.

Color Fastness to Water:

The test method by which this test is carried out is AATCC 107-1991 or ISO 105 E01. This method is to assess the degree of cross staining which may occur when garments are left in contact when damp. The test measures the resistance to water of any colored textiles.

The Test Specimen is sandwiched between the two pieces of multifibre strip and is kept under pressure of 12.5 kPa. This is kept for 4 hours at 37C in water.

After the treatment the test specimen is removed, dried and change in color is assessed with the help of Grey Scale.
