Bradford Count
The Bradford system (also known as the English Worsted Yarn Count System or spinning count or Bradford count) is a way to assess the fineness of wool. To measure the fineness of sheep wool fibre before microscopes and lasers were used, English wool handlers in the city of Bradford Bradford is a city and the administrative centre of the City of Bradford district in West Yorkshire, England. The city is in the Pennines' eastern foothills on the banks of the Bradford Beck. Bradford had a population of 349,561 at the 2011 ... described wool by estimating (with experienced eyes) how many hanks of single-strand yarn could be made by a good spinner from a pound (0.45 kg) of "top" (cleaned combed wool with the fibres all parallel). The finer the wool, the more hanks could be spun: from a pound of "62s," for example, sixty-two such hanks could be made. Spinning counts range from about 32s for coarse carpet-wool to over 80s the finest wools. The Bradford System is widely used amo ...

Wool
Wool is the textile fibre obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but lack c ...

Pound (weight)
The pound or pound-mass is a unit of mass used in British imperial and United States customary systems of measurement. Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly , and which is divided into 16 avoirdupois ounces. The international standard symbol for the avoirdupois pound is lb; an alternative symbol is lbm (for most pound definitions), # ( chiefly in the U.S.), and or ″̶ (specifically for the apothecaries' pound). The unit is descended from the Roman (hence the abbreviation "lb"). The English word ''pound'' is cognate with, among others, German , Dutch , and Swedish . These units are historic and are no longer used (replaced by the metric system). Usage of the unqualified term ''pound'' reflects the historical conflation of mass and weight. This accounts for the modern distinguishing terms ''pound-mass'' and ''pound-force''. Etymology The word 'pound' and its cognates ul ...
