Unformatted text preview: D. 1. Obtain a piece of 15 x 24 inch greige cotton fabric and cut 6 2 x 2 inch pieces. 2. Prepare a 300-mL desizing bath with these chemicals: 10mL of 100% Synthazyme HS-T, 50mL of 10% NaCl, 12mL of 1% Renex 36, and the rest water. 3. Insert fabric sample in beaker and heat to 80 deg C in the Pyrotec Machine. Run sample through padder to remove most water and dry in oven at 100-110 deg C. Calculate % weight loss. 4. Record observations of various tests on different swatches of fabric....
