Repellent. A general term for solid-colored, plain-woven, six-quarter-wide cloths used for making ladies' and children's wraps and winter dresses, ordinarily woven with cotton warp and wool weft, though occasionally made of pure wool; sometimes called waterproof. When first made, they were woven so thick and close as to repel rain and moisture, hence the name repellent or waterproof.
