What reading level is The Structure of the Wool Fibre in Its Relation to the Use of Wool for Technica book?
To quickly assess the difficulty of the text, read a short excerpt:
Formerly it was considered a sufficient definition between the two to say that worsted was made from long wool, and woollen yarn from short wool ; or the difference was frequently expressed by saying that worsted yarns were made from combed, and woollen yarns from carded wool. These distinctions were generally true, because formerly nothing but long wools could be spun into worsted, and short wools 262 STRUCTURE OF THE WOOL FIBRE.
into woollen yarn, and the usual process was combing for the wor...sted and carding for the woollen yarns ; but neither of these definitions expressed the essential difference between the two which is really determined by the method in which tne fibres are arranged in the two threads.
The improvements in machinery, especially in comb- ing, have rendered it possible to comb short wools which at one time could only be carded, and many wools are now treated by carding preparatory to combing, as well as many short wools being spun into worsted. The real difference lies not in the method of preparation, but in the difference of mechanical constraint which is put upon the fibres in the two different classes of yarn.
