Garments made of wool fabrics are an important part of the wardrobe, especially for people who live in the northern section of the United States, where cold weather is common during a large part of the year. Researchers at the Agricultural Experiment Stations at South Dakota State College and the University of Minnesota have undertaken the present investigation cooperatively in order to observe (1) the relative service to be expected from different weights of one type of worsted fabric, (2) the relation of dry cleaning and storage to service, and (3) the possible interpretation of physical test date in terms of wear. Sufficient yardage of each weight of material was purchased to provide for experimental trousers to be worn so as to show the effects of daily use and for laboratory controls on unworn cloth. These controls provided measurements for new materials at the beginning of the experiment, after storage, and after storage and dry cleaning for periods equivalent to the wearing periods for the trousers.
