Last week (July 14-20, 2025), the market trend for high-speed spinning of raw material nylon PA6 slices declined, with weakened cost support and high inventory levels in the market. The supply side performed well, while the demand side remained weak. Some nylon filament manufacturers had poor shipments, and low-priced sources increased in the market. Amidst mixed news in the market, the price of nylon filament continued to decline.
Nylon filament prices continue to decline
According to the Commodity Market Analysis System of Shengyi Society, last week (July 14-20, 2025), the price of nylon filament fell weakly. As of July 20, 2025, DTY (premium product) of nylon filament in Jiangsu region; 70D/24F) quoted 14460 yuan/ton, a decrease of 240 yuan/ton compared to the previous period, with a weekly decrease of 1.63%; Nylon POY (premium product; 86D/24F) quoted 12200 yuan/ton, a decrease of 200 yuan/ton compared to the previous period, with a weekly decrease of 1.61%; The price of nylon FDY (premium product: 40D/12F) is reported at 15050 yuan/ton, a decrease of 275 yuan/ton from the previous period, with a weekly decline of 1.79%.
Insufficient support on the raw material side
In terms of cost: Last week (July 14-20, 2025), the spot market price of caprolactam was weak during the week, with Sinopec’s high-end caprolactam closing price of 9095 yuan/ton. The nylon PA6 chip market experienced a slight decline, indicating insufficient support on the cost side. As of July 20, 2025, the benchmark price of caprolactam in Shengyi Society was 8943 yuan/ton, with a weak price and a weekly decline of 0.43%. During the week, the market price of high-speed spun nylon PA6 slices slightly decreased, with weak cost support being the main factor.
Supply and demand: During the week, some nylon filament manufacturers have lowered their operating rates, resulting in a decline in overall market supply. However, industry inventory levels continue to increase, leading to poor performance on the supply side; The demand in the end market is weak, and some downstream manufacturers have reduced production or switched production, resulting in a decrease in demand for nylon filament. It is difficult to find favorable support from the demand side, and many parties are following suit with rigid demand. Many industry players are adopting a cautious and wait-and-see attitude.
Future forecast
Cost aspect: In terms of caprolactam, the expectation for pure benzene is weak, and slice manufacturers have low enthusiasm for purchasing caprolactam. It is expected that the caprolactam market will continue to decline next week; In terms of PA6 slicing, cost support is limited, and the supply level of PA6 slicing market may continue to improve. Downstream market demand is weak, and it is expected that the market price of nylon PA6 slicing will decline.
Supply and demand: July belongs to the off-season of traditional demand in the market, and coupled with the lack of signs of improvement in terminal market demand, downstream market procurement enthusiasm is not high. Therefore, it is expected that the demand for nylon filament market next month may decrease. If there is no significant improvement in demand, under the pressure of large inventory, some nylon filament manufacturers may have the possibility of reducing production capacity, while the industry continues to release new production capacity. Therefore, it is expected that the supply of nylon filament market will decrease next month.
Overall, both the upstream raw material caprolactam spot market and the nylon PA6 chip market are likely to continue to decline, with a lack of cost support and difficulty in improving downstream market demand. The demand side is dragging down market trends, and under the dual negative factors, analysts from Shengyi Society predict that the short-term nylon filament market prices will continue to be weak, with a expected decline of 100-300 yuan/ton.
