420-423Anthocyanin extracted from
mulberry fruit has been applied onto the cotton fabric for protection against
ultraviolet radiation. The amount of anthocyanin present in the mulberry
extracts
has been evaluated by pH differential
method. The effect of anthocyanin concentration and its <i style="mso-bidi-font-style:
normal">pH on the ultraviolet protection factor (UPF) of the fabric is
studied. The study shows that higher concentration of anthocyanin at acidic pH yields higher UPF to the fabric than
lower concentration. It is also found that there is no difference in UPF
between the fabrics treated with crude mulberry fruit extract and the fabric
treated with anthocyanin extracted from the mulberry fruit
