Indian Central Cotton Committee Technological Laboratory The Foundations of Yarn-Strength and Yarn-Extension June 1933

1933

As the strength of an element of yarn depends upon its weight and twist from a knowledge of this relation and also of the variation in the weights of the elements along a yarn it should be possible to predict the strengths of weak places and their distrbution and hence the strength of any length of the yarn. [...] As the strength of an element of yarn depends upon its weight and twist from a knowledge of this relation and also of the variation in the weights of the elements along a yarn it should be possible to predict the strengths of weak places and their distrbution and hence the strength of any length of the yarn. [...] In view of these difficulties in connection with the relation of yarn strength to spinning-value and the consequent difficulties that arise in the attempt to correlate the spinning-value with the fibre-properties the criterion of spinning-value used in the present paper is the "highest standard warp count " an account of which is given in the next paragraph.

[...] The value of the fibre-rigidity is calculated from the following formulR =-- 8n3 K/ t2 where R is the fibre-rigidity in dyne-cm2; K is the moment of inertia of the aluminium rod; l the length of the fibre; and t the period of torsional vibration.
