The woollen yarn Fig. 23 Camelhair Noils (Specimen A: From 1st Combing. Specimen B: From 2nd Combing) wastes should be regularly collected, graded, and reduced to a wool substitute. From worsted spinning mills a constant marketable supply of this class of waste yarn is obtainable. Like noils, it is a pure wool product, when resulting from English combing; but there are, in addition, waste yarns derived from French combing, which may be an admixture of wool and cotton, as also worsted yarns, in which, in the operations of doubling and twisting, cotton threads are combined with the worsted threads, and in all these yarns the cotton has to be removed by carbonizing. Prior to 1850, worsted-yarn by-products were only considered as fit for cleaning waste. Now they are of such intrinsic value as to be extensively used in woollen factories, in which the better as well as the medium grades of fabrics are produced. They represent an annual British supply of recovered wool fibre amounting to, approximately, 30,000,000 lb. When the yarn-pulling machine was introduced, the common custom was to store such "waste" as a kind of refuse. It is said that the inventor of the machine approached a firm of carpet manufacturers having a huge heap of this sort of waste yarn stored in the mill yard, and received permission to experiment in pulling it. The result was what may be defined as a "yarnshoddy," which has become such an important material in the woollen industry. As the worsted spinning trade is divisible into Botany, Crossbred, Mohair, Alpaca, Camelhair and Cashmere yarns, there are pulled wastes made of staples of these d...
