In mule running, it is important to adjust the conditions of carriage displacement, spindle revolution and sliver delivery. To check the suitability of these conditions, the degree and the profile of tension generated during the drafting is discussed.
A tester (Fig. 1) has been designed to draft the woollen slubbing under various conditions of draft ratio and spindle revolution, and to measure the tension generated.
By this tester, the tensions for seven samples are measured under the same condition as shown in Fig. 3. The results are shown in Fig. 4. Various profiles of tension are mainly influenced by the tensile properties of the material, and partly influenced by the counts and fiber length.
