A-grade raw cotton is a kind of super-grade cotton material which is sorted and purified by machine on the basis of Xinjiang long-staple cotton. Because the output is scarce, it is mainly used to make expensive handicrafts. It is rarely used for bedding.

Introduction to cotton picking

The growing period of cotton is 200 days, and the picking period is concentrated in 40 days. From September to 10 every year, cotton must be picked, otherwise, by the end of 10, cotton peaches will have landed. Due to the large population and small land in Xinjiang, while the cotton output in Xinjiang is increasing day by day, there are also "joys and sorrows"-a serious shortage of cotton picking manpower.

Every time cotton matures, it is impossible for local cotton farmers to harvest all cotton before the end of frost-free period, and there are still technical obstacles to realize large-scale promotion of mechanized picking. In this way, every September and October, millions of "cotton pickers" go to Xinjiang to pick cotton.
