Lint Retrieval at Ginning: Further Study of Bale Value and Spinning Performance

Cotton from the same field was harvested and ginned in two replications three weeks apart. The ginning treatments consisted of using a conventional machinery sequence without fiber retrieval and recycling, and using the same machinery se quence with continuous fiber retrieval recycling. Ten half-bale batches from each harvesting were processed using each ginning treatment. Samples from each batch were tested for differences in raw cotton properties, yarn manufacturing performance, and chemical finishing. Bale weights were improved 2.2% by the retrieving and re . cycling process. More of the bales from the with retrieval and recycling process were reduced in grade because of grass in the sample than from the control bales. There were no significant differences in the quality and performance factors of the raw cotton and yarn which could be attributed to differences in the ginning treatments. Some of the factors evaluated did show statistically significant differences due to the interval between harvest dates.
