QuestionQuestion

1. Determine the effectiveness of your desizing procedure by examining the wettability and your calculated percent weight loss data. What experimental errors might have significant influence on your weight data?

2. Why are knitted fabrics not desized?

3. Describe two continuous production methods for desizing woven fabrics. Be certain to include how each method provides dwell time and temperature for desizing.

4. Consider the BATCH desizing of 500 lbs. of 100% cotton oxford cloth for shirts. Assuming a 20:1 liquor ratio and use of the same chemicals and concentrations you used in this experiment, calculate how many pounds of each chemical (as received) will be required for this process. If 1.00 gal. of water weighs 8.34 lbs., how many gallons of bath will be required? SHOW ALL WORK.

5. From your data, calculate the final percent concentration of enzyme on weight of the fabric (owf) and on weight of the bath (owb). Calculate the final percent concentration of the salt (owb) and wetting agent (owb). For these calculations, assume that 1.00 mL weighs 1.00 g. Calculate the liquor:goods (LR) ratio. SHOW ALL WORK.

01) Determine the effectiveness of your desizing procedure by examining the wettability and your calculated percent weight loss data. What experimental errors might have significant influence on weight data.

In this lab we desizing the cotton fabric.in procedure section of the lab session we examine the wettability and we calculated the weight loss. Considering wettability we can find the adsorption ability of carbon fiber (CF) in epoxy solution and the interfacial properties of CF/epoxy .also endows it with improved hydrophilicity for further wet processes. Considering weight loss we can analyze the ability of oxidation of the cotton fabric...
