Santiago Rubio Robin Kirkman Experiment 8: Disperse Dyes: Measurement of Dye Shade by K/S October 21, 2010 I. Part 2 A. Observations: 1. With such a small amount of dye (.1%) our fabric had a bright pink shade. 2. Our multifiber strip was also shades of pink. 3. The initial color of the dye bath was a very light red color. 4. After the experiment the dye bath was a very light pink color. 5. The spectrophotometer gave us reflectance readings at 520 nm of 5.49, 5.35, and 5.37. 6. We used Dr. Beck’s Data to create the calibration curve. 7.
