Laundering Practices and Results of Homemakers Using Coin-Operated LaundriesSchool of Consumer and Family Sciences, Purdue University, West Lafayette, Ind. 47907
New York State College of Human Ecology, Cornell University, Ithaca 14853 This research examined factors that influenced the laundering results of homemakers using the coin-operated laundry. Data were obtained by personal interview with 243 home makers at coin-operated laundries and from reflectance measurements on soiled and laun dered pillowcases and standard soil cloth. Interrelationships were examined using step wise multiple regression analysis. Whiteness values for the laundered pillowcases covered a wide range; most values were much lower than for new pillowcases. On the average, the laundered pillowcases were ten units whiter than the soiled ones. The laundering results were related to the extent of soiling prior to washing, the change in whiteness of standard soil cloth, color index of the wash load, household size, age of the homemaker, and socioeconomic position of the household.
