2. study of color fastness of fabric from the giant Caterpillar fiber coated and uncoated.Nano zinc oxide and stained with water from the water-stained Tako. Make a test colorfastness to light by fabric to takklang the Sun in time 12.00. 00-14.00 (Make a 3 Pack at the same time).1. measuring the color of the fabric prior to four (a substance detecting is the interface with Nano syncing. Oxide dye from fabric with high water, detecting the Tako is an interface with Nano-zinc oxide that is stained from water, Tako, fibre textile from the giant Caterpillar stained from water, Tako and cotton dyed fabric from water using each Tako. Each 4-piece dyed anodizing in different concentrations of 25%, 50%, 75% and 100%).2. bring four to 14.00 pm-12.00 on time. Am every day for ten days, and then measure the results of the last day to see the color value is changed from the first day.3. find the average changes in three sets and then compare to see color fastness to light of each fabric.
