The Impact of New Spinning Technology on the Engineered Yarn Quality Factor of Egyptian Cotton. Part: I Condensed Spinning

Abstract:

In the present work a data mining [DM] of condensed spinning that runs in the Egyptian spinning mills were extracted and manipulated to produce tables & exhibits where they reveal the Egyptian yarns quality levels via Engineered & upgraded yarn quality factor EUG – YQF or via  EUG – RYQF (Engineered upgraded relative yarns quality factor). The last one gives a figure about the percentage improvement or loss in the compact spun yarns quality. For the processed cottons in the spinning mills it was found that the EUG – FQI (Engineered upgraded fiber quality index) was ranging from highest value (40k) for G80 to the lowest value (31k) for G70.

The definition of the new quality measures are:

For weaving - high twist yarns, the value of  is ranging from 69 k -102k for compact yarns & from 49k – 86k for ring yarns for texs  7 to 15 respectively, The % improvement in yarn quality varies from 40 % - 19% (average%=30%) The high improvement for tex 7 i.e for fine yarns.
