VSF capacity expansion of China is slowing down in recent years, but the operation of existing producers is generally stable. Compared with demand of improving flexibility, suppliers is hard to keep firmer attitude in pricing. Coupled with the fluctuation of production cost, the upward momentum of VSF is weaker than that of cotton. In recent years, it is common to see more sales at low price, but the trading volume is limited when the price is low. Spinners who produce various varieties of yarn do not usually consume steady and a large amount of VSF, so they show less enthusiasm when VSF price drops.
