Transfer capability, specific steps are as follows:
Step 1: photothermal conversion heat-accumulation temperature-adjustment cotton fabric equal part obtained being become into five parts of samples, takes a copy of it to be used as and washes
Wash 0 sample；
Step 2: according to AATCC 61-2003 " fabric color fastness to washing standard ", key step is as follows: distilling to 150mL
The AATCC1993WOB standard detergent washing powder WOB solid powder of 225mg is added in water, preparing becomes WOB solution, is added surplus
Remaining sample, with aluminium-foil paper sealing container, in 49 DEG C of heating water baths washings on shaking table, in washing 25min, 50min, 75min,
Whole samples are taken out when 100min, short rinse 3 times in distilled water, after be added in original WOB solution and continue again
Washing takes out whole samples short rinse 3 times, natural air drying in distilled water when 125min, takes a copy of it sample conduct
The sample that washing is 1 time；
Step 3: reconfiguring and repeat the operation of step 2, first with WOB solution identical in step 2, addition remaining sample
Washing 2 times, 3 times, 4 samples are obtained afterwards；
