Last week (July 7-13, 2025), the upstream raw material market prices were weak and fell, with insufficient cost support. Downstream manufacturers held onto their demand and followed suit, with no positive support from both the cost and demand sides. Some downstream manufacturers reduced production or stopped production for holidays, and the demand side remained weak. Some nylon filament manufacturers had poor shipments, and low-priced sources increased in the market. With mixed news on the market, the price of nylon filament was under pressure and slightly decreased.
Nylon filament prices are under pressure and falling
According to the Commodity Market Analysis System of Shengyi Society, last week (July 7-13, 2025), the price of nylon filament fell weakly. As of July 13, 2025, DTY (premium product) of nylon filament in Jiangsu region; 70D/24F) quoted 14700 yuan/ton, a decrease of 160 yuan/ton compared to the previous period, with a weekly decrease of 1.08%; Nylon POY (premium product; 86D/24F) quoted 12400 yuan/ton, a decrease of 125 yuan/ton compared to the previous period, with a weekly decrease of 1.00%; The price of nylon FDY (premium product: 40D/12F) is reported at 15325 yuan/ton, a decrease of 125 yuan/ton from the previous period, with a weekly decline of 0.81%.
Short term support for raw material storage
In terms of cost: Last week (July 7-13, 2025), the spot market price of caprolactam was relatively strong during the week, with a weekly settlement price of 9160 yuan/ton for Sinopec’s high-end caprolactam. The nylon PA6 chip market experienced a slight decline, with insufficient support on the cost side. As of July 13, 2025, the benchmark price of caprolactam in Shengyi Society was 8970 yuan/ton, with a weak price and a weekly decline of 2.92%. During the week, the market price of high-speed spun nylon PA6 slices slightly decreased, with a 2.2% drop in nylon PA6 prices, mainly due to weak cost support.
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.

According to the Commodity Market Analysis System of Shengyi Society, the trading atmosphere in the polyester filament market was calm on July 14th, with few bulk transactions. Mainstream polyester factories’ quotations remain stable, while some polyester factories have made small-scale reductions. Actual small-scale transactions are mainly negotiated between the two parties. The mainstream polyester filament factories in Jiangsu and Zhejiang offer POY (150D/48F) prices ranging from 6750-7050 yuan/ton, polyester DTY (150D/48F low elasticity) prices ranging from 7700-8050 yuan/ton, and polyester FDY (150D/96F) prices ranging from 6900-7100 yuan/ton.
Today, WTI crude oil futures prices rose to $68.45 per barrel, up $1.88 per barrel. Brent crude oil futures prices rose to $70.36 per barrel, up $1.72 per barrel. On the demand side, the purchasing enthusiasm of weaving and reloading factories is not high, and the overall transaction volume is slow. The inventory of polyester filament from polyester manufacturers is not large, and some varieties are oversupplied. However, due to the psychological pressure of cost, Shengyi Society expects that the overall polyester filament may stabilize in the short term, but it cannot be ruled out that there will be periodic replenishment procurement this week under the support of rigid demand.

According to the monitoring of the commodity market analysis system of Shengyi Society, the price of activated carbon at the beginning of the week was 12633 yuan/ton, and the price of activated carbon at the end of the week was 12700 yuan/ton, with a price increase of 0.53%.
Most domestic manufacturers of activated carbon have seen price increases this week. The ex factory price of activated carbon for coconut shell water purification in East China is between 9000-13000 yuan/ton. Coconut supply is insufficient in most parts of Asia, and the market demand for coconut shell carbonization materials, activated carbon, and other coconut products is high, which supports the price increase of coconut shell activated carbon.
Internationally, Southeast Asia, as the main source of coconut shells in the world, will encounter multiple natural disasters in 2024. Thailand will experience a reduction in coconut production due to drought and pest infestations. In the short term, the import price of coconut shell charcoal will continue to operate at a high level. In June 2025, the import price of coconut shell carbonized material specifications, including taxes, has exceeded the 8000 yuan/ton mark.
Prediction: The shortage of raw materials has not improved yet, and it is difficult for factories to purchase. Some enterprises have half started and half stopped production, resulting in insufficient output and limited supply. It is expected that the price of activated carbon will mainly fluctuate and strengthen in the short term.

According to the Commodity Market Analysis System of Shengyi Society, as of July, the aniline market has experienced a decline, with the average price dropping to 7025 yuan/ton as of the 9th. Compared to the beginning of the month at 7900 yuan/ton, the decline was as high as 11.08%. One reason for the analysis is that the price of raw material pure benzene has entered a downward channel, and aniline is significantly dragged down by costs. Secondly, the maintenance equipment was restarted in July, and the market supply was filled quickly, causing the company to accumulate inventory. The third reason is that the downstream is in the off-season, with many small single houses and a strong atmosphere of observation.
Market forecast: In the short term, there are many negative factors in the aniline market, and there is currently no positive boost. The price of aniline has fallen to a low level, and it is expected that the downward trend in the future will slow down, with weak consolidation as the main operation.

Market mentality warms up
Recently, the domestic acrylic acid market has shown a moderate upward trend. As of July 7th, the benchmark price of acrylic acid in Shengyi Society was 7233.33 yuan/ton, an increase of 0.93% compared to the beginning of this month (7166.67 yuan/ton). It is worth noting that although the price of raw material propylene has fallen today, the prices of downstream butyl ester and isooctyl ester products have continued to rise. At present, the market presents the following characteristics: downstream procurement is still dominated by rigid demand, but the overall trading atmosphere in the market has significantly rebounded compared to the previous period; Combined with the fact that some production enterprises’ equipment is still under maintenance this week, the market supply remains tight. Under the dual effects of improved supply and demand patterns and cost support, the acrylic acid market as a whole is showing a stable and positive operating trend.
Monitoring data shows that the price of acrylic acid has recently increased by 0.93%, mainly due to the combined effect of the following market variables.
Cost end
Recently, the international crude oil and polypropylene futures markets have continued to weaken, leading to a synchronous decline in propylene spot prices in Shandong region. As of July 7th, the benchmark price of propylene in Shengyi Society was 6700.75 yuan/ton, a decrease of 0.3% compared to the beginning of this month (6720.75 yuan/ton). From the perspective of market supply and demand, although the industry’s operating rate remains relatively stable, different manufacturers have differentiated their price adjustment strategies: some companies choose to raise prices and wait, while others actively lower their quotes, resulting in a significant decrease in overall trading activity. It is worth noting that the concessions on the raw material side have eased the production cost pressure on downstream enterprises, especially the profit level of the acrylic acid industry has significantly improved.
Need End
Currently, the acrylic ester market is showing an upward trend, with prices of butyl acrylate and isooctyl ester showing particularly strong performance. Affected by the low inventory of acrylic acid at the raw material end and the rise in alcohol prices, ester enterprises are facing increased cost pressure. Some manufacturers have voluntarily raised their prices, driving market transaction prices to steadily rise. This market change has provided positive feedback to the acrylic acid market, further consolidating its price support.
Overview of Market Trends
The peak season effect is evident, with strong support for the acrylic acid market. Driven by the rebound in seasonal demand, the trading atmosphere in the domestic acrylic acid market has significantly improved. On the supply side, the power rationing factors that previously constrained production have been basically eliminated; The demand side benefits from the opening of export windows, the stimulation of reduced shipping costs, and the release of downstream replenishment demand. The current market is experiencing a strong oscillation trend, supported by both the cost line and demand line.
