Cashmere wool, usually simply known as cashmere, is a fiber obtained from Cashmere goats and other types of goat. The word cashmere derives from an old spelling of Kashmir. Cashmere is fine in texture, strong, light, and soft. Garments made from it provide excellent insulation. In the United States, under the U.S. Wool Products Labeling Act of 1939, as amended, (15 Uction 68b(a)(6)), states that a wool or textile product may not be labeled as containing cashmere unless:
such wool product is the fine (dehaired) undercoat fibers produced by a cashmere goat (Capra hircus laniger);
the average diameter of the fiber of such wool product does not exceed 19 microns; and
such wool product does not contain more than 3 percent (by weight) of cashmere fibers with average diameters that exceed 30 microns.
The average fiber diameter may be subject to a coefficient of variation around the mean that shall not exceed 24 percent.
