Question 38 is based on the following picture POLYPROPYLENE COMPOSTE FIBER POLYETHYLENE POLYACRYLATE of nhasnigne b o prhonip Source: Scientific American, December 2000 Most materials used in a disposable diaper are synthetic. Polypropylene, used in winter athletic underwear, makes up the inner layer; it is soft and stays dry, drawing fluid away from the skin. At the core is the polyacrylate superabsorbent powder, combined with fluffy cellulose. A layer of fiber (cellulose or synthetic) fights gravity by distributing fluid over the entire surface of the powder instead of letting it pool in one spot. The outermost polyethylene; it keeps in fluid but lets out vapor. Adhesives hold it all together: elasticized nydrophobic polypropylene cuffs around the highs contain leaks; Velcro or sticky tabs hold ne diaper on the baby. layer is mostly microporous 8. A disposable diaper is made of both synthetic and natural polymers. Which one of the following is a supporting detail useful to promote the use of disposable diapers? Diapers olzaenomo A. may have allergens in the fiber area B. add to the landfills in the United States C. allow babies to be changed less often D. do not allow air to circulate around babies E. are superabsorbent so babies may toilet-train later
