Indian Central Cotton Committee Technological Laboratory Technological Report on Standard Indian Cottons August 1938

These factors are (1) the supply of the type relation to the competing types (2) the existence of an abnormally high or low demand for the type (3) the existence of a general or prolonged strike in the textile industry or the threat of a boycott from large scale. [...] When as is often the case the object is to compare the performance of two or more cottons the size of a sample is of seconary importance provided it is the same for 'all the samples which are spun under similar conditions Where the performance of a single cotton"6 is to be considered the results of the Laboratory test will still provide a useful guide to its performance in a mill. [...] - It has been customary in the past to give in each issue of this Bulltin full details of the machinery and the spinning technique employed in the spinning tests of the appgratus and the methods employed in the fibre and the yarn tests and of the standards of yarn strength and twist adopted at the Technological Laboratory. [...] For the single thread test the humidity is noted at the beginning and at the end of the tests on each bobbin and the mean of these two values is taken as the humidity for that bobbin giving in all 10 values for each count. [...] Owing to a change in the method of the determination of the mean fibre-weight per inch introduced in 1929-30 to which a reference'has been made t bove the values for the sirbsecplent seasons are not strictly comparable with those for the earlier season It will 1;e seen that there is very little correspondence between the degree of variability of the standard Indian cottons with respect to all the
