Indian Central Cotton Committee Technological Laboratory The Effect of Raising the Middle Roller and Some other Factors on the Yarn Strength of Sindhi Cotton August 1936

1936

Sixteen samples of yarns spun in a local mill were tested for strength with the object of ascertaining the influence of the following three factors i) the height of the bottom middle roller with respect to the other two rollers (ii) the weight of the top middle roller and (iii) the weight of the top back roller. [...] one affected the yarn-strength one way or another depending upon the weight of the top back roller."2 But with 1/32 middle roller elevation the use of the lighter middle rollers gave an increase in the yarn-strength regardless of the weight of the top back roller. [...] III.—The effects of using ordinary or the heavy back roller.— (i) The effect of replacing the ordinary with the heavy back roller is on the whole a reduction in yarn-strength the decrease being greater with the smaller than with the larger middle roller elevation. [...] (ii) The adverse effect of using the heavy back roller becomes progressively less as the weight of the top middle roller is reduced the only exception to the rule being the lightest of the four rollers weighing only 2 oz. [...] These were as follows :—(1) The height of the bottom middle roller with respect to the other two rollers (2) the weight of the top middle roller and (3) the weight of the top back roller.
