Dyeing cloth on the project will go through several small samples of a large number of colored dye before dyeing , but will first disperse dye before dyeing sample fully dissolved in water , according to the recipe needs only to extract the dye to prepare a dye after dye liquid purpose of this study is to understand the dye concentration of each dye by placing a few days later , the stain resistance of reproduction using a laser particle size analyzer to measure the particle size by placing the dye to change the number of days , and UV spectroscopy changes in absorbance values measured dye , and then through the computer spectrometer interpretation , to find the curve to find shade , allows modulation of the dye in certain reproducibility in minimize unnecessary costs and loss of human resources at a small sample of some dye .
