Indian Central Cotton Committee Technological Laboratory Application of Different Systems of High Draft Spinning to Mixings of Indian Cottons March 1932

This improvement may be effected in the opening and cleaning stage in the preparation of a uniform lap and sliver in the elimination of short or knotted fibres in the parallelisation of the fibres or in the exercise of a gentle and elastic control in the break draft region of the fly frames or the ring frame. [...] These are due in the first place to the mutual interaction of the fibres and in the second place to the presence of short fibres in the roving. [...] The main work of the Technological Laboratory of the Indian Central Cotton Committee is the testing of cottons for the Agricultural Departments in India and it has no concern with furthering the sales of any particular machinery used in the textile industry. [...] If we add up the figures in the horizontal rows of Table 7 the total in each case will be an index of the number of breakages for a given mode of spinning irrespective of the cotton used. [...] Furthermore it will be seen that reduction in the number of yarn breakages with increase in twist is noticeable most of all in the ordinary system single roving band drive ; and more so in the case of the two other modes of spinning with the ordinary system than with any of the high draft systems.
