The experiment was completed in order to learn which cross-sectioning technique worked the best on acetate and polyester. The experiment consisted of taking acetate and polyester and using the cork and plastic plate method on each, observing both techniques under the microscope, and making conclusions about each method used. The results of the experiment show that as each different method was used, the fibers looked a little bit different under the microscope. 2. OBJECTIVES (1) To find the method that can be used to get the best cross section. (2) To primarily utilize the cork and the plastic plate methods. 3. INTRODUCTION This experiment was important to conduct because it taught how to use different cross- section techniques. The results from this experiment could be used to show the purpose of cross-sectioning techniques and how they can be used to identify different fibers, for dye penetration, and to find out the fiber denier and cross-sectional area. This experiment would be important to conduct to identify certain fibers and the shape of the fibers. 4. MATERIALS A Block A Razor 2 Glass Slides A Microscope 2 Pieces of Cork 2 Plastic Plates 4 Pieces of Thread 2 Needles A Small Amount of Acetate A Small Amount of Polyester 5. PROCEDURE 1. First the microscope was set up and plugged in. 2. Next the materials and fibers were gathered. 3. First the cork method was used on the acetate and polyester. 4. Then both needles were taken and double threaded.
