Polyester filament: "Supply comes on the scene after the cost sings", and the reduction of plant production supports the price rise

From February to March, the price of polyester filament showed a strong cost-driven rise. After entering April, the melt cost first rose, then fell, and then rebounded due to the influence of crude oil and polyester raw materials. However, the price of polyester filament showed an obvious first. Steady and rising trend, cost and price correlation weakened. During this period, the fundamentals of supply and demand of polyester filament have gradually changed. Among them, the change in supply-side indicators in April replaced cost and became the strongest driving factor affecting the price of polyester filament.
