Cotton assorting method for knitting yarn production

The invention discloses a cotton assorting method for knitting yarn production, and relates to the field of knitting yarn production. Large assorted cotton is made when raw materials are selected, the raw cotton producing area, the processing factory and the raw cotton performance are selected, and the factory entering time of each batch is arranged according to the cotton assorting requirement. And finely assorting cotton after the raw materials enter a factory. Eight batches of cotton are assorted, the horse value difference of each batch is controlled to be within 0.5, the yellowness value difference is controlled to be within 0.2, the batch splicing proportion of each time is controlled to be within 5%, and during cotton assorting and batch splicing, various physical indexes of the raw cotton in the same production place are close to each other, so that the quality index of each group of assorted cotton is stable, and the southern and northern Xinjiang raw cotton which is large in raw cotton production pl
