Effect of mass of seed cotton and its lint quality on yarn properties

Abstract

Reduction in variation of fibre properties within particular fibre groups to get excellent fibre and yarn qualities from the available raw material and categorization of seed cotton prior to ginning with respect to their mass has been explored. For appropriate utilization of raw material to produce yarn of a particular quality, the manually picked seed cottons were grouped with respect to their mass measured with an accuracy of 0.001g. The grouped seed cottons were then ginned on roller gin with four different roller and beater speed combinations and fibres of each group were tested using AFIS and HVI as per the standard procedure. The yarn samples were produced as per the sequence of process used for carded cotton yarn. The separation of the seed cottons with respect to their mass results in the categorization of fibres with respect to their physical properties. The higher mass of seed cotton results in superior fibre properties and vice versa. Similar to fibre properties, a significant enhancement in yarn quality is also observed, particularly in the samples ‘101-150mg’ and ‘151-200mg’ for both 50s and 60s Ne count yarns.
