Cassimere
kas'si-mer, a general term employed to designate a large class of woolen fabrics used for men's clothing. They are woven plain, twilled, and in a variety of fancy effects. The yarns are spun from wool prepared by the carding process. The patterns are produced in the loom and are usually plaids, checks, and stripes in quiet colors. The quality of cassimere differs greatly. It is made sometimes with a cotton warp and wool or shoddy weft. This is called union cassimere. It has been estimated that fully one-half of the men's ready-made clothing produced in the United States is of cassimere.
