price trend
According to the bulk ranking data from Shengyi Society, the recent domestic PC market has shown weak consolidation, with some spot prices of certain brands experiencing a narrow decline. As of July 22nd, the benchmark price of Business Society PC hybrid is around 14333.33 yuan/ton, with a price increase or decrease of -0.92% compared to early July.
cause analysis
Supply side: Since mid July, the load of domestic PC aggregation enterprises has stabilized. The interval flat coal Shenma has resumed after a short shutdown, with the industry’s average operating level rising narrowly to 77%, and the weekly average output approaching 65000 tons. The on-site supply is abundant, with high inventory levels remaining stagnant, and the pattern of ample PC supply remains unchanged. After the addition, there is currently no news of maintenance released in the market, and the pressure on shipments has not decreased. The market supply side has poor support for PC prices.
In terms of raw materials: From the above chart, it can be seen that bisphenol A fell and then turned sideways in mid July. Upstream acetone and phenol also fluctuate at low levels, dragging down spot prices. Meanwhile, bisphenol A is also affected by the supply-demand imbalance, with little change in demand and a lack of upward momentum in the market. Overall, the intraday market trend of bisphenol A has weak support for PC costs. However, with PC prices currently at historically low levels, the easing of cost pressures has also given PC some room for maneuver.
On the demand side: Currently, July is the traditional off-season for PC, with downstream factories experiencing lower loads and weak inventory, mainly due to rigid demand, further dragging down the consumer end. Due to the long-term weak market dynamics in the industry, high social inventory, and abundant on-site supply, the supply-demand contradiction within the range has not improved. At present, terminal enterprises are cautious in purchasing new orders, and their trading performance continues to be dominated by contract delivery. Merchants tend to have a wait-and-see attitude, buyers are resistant to high priced goods, and the flow of goods in the market is slow. Overall, the demand side has weak support for PC spot prices.
Future forecast
Recently, the domestic PC market has been consolidating weakly. The upstream bisphenol A market is consolidating at a low level, which provides poor support for the cost value of PC. The upstream concessions have made it difficult for the industry to operate at a high level, and the overall load of domestic PC aggregation plants has remained stable with little increase. The pattern of strong supply remains unchanged, while the downstream demand has obvious characteristics of off-season. At present, it is difficult to see any positive developments in the market, and industry players are adopting a wait-and-see attitude towards the future. However, with low PC prices and limited room for decline, it is expected that the PC market may enter a stalemate in the future.

According to the Commodity Market Analysis System of Shengyi Society, the focus of the PTA market has slightly shifted in recent times. As of July 21, the average price of PTA market in East China was 4825 yuan/ton, an increase of 1.89% compared to July 16.
The crude oil market prices fluctuated and adjusted slightly. As of the 18th, the settlement price of the September WTI crude oil futures contract in the United States was $66.05 per barrel, and the settlement price of the September Brent crude oil futures contract was $69.28 per barrel. The main positive factors for the rise are the continuation of the traditional fuel consumption peak season in the United States, market concerns about the fragility of the geopolitical situation, and the continued US sanctions stance against some oil producing countries.
The PTA market went out of stock from March to June, and in July, maintenance facilities resumed production one after another, increasing the supply margin. The market lacks unplanned news guidance. In addition, with the start of trial production of 3.2 million tons of PTA new capacity in East China, the supply has increased, and the current operating rate of the PTA industry is around 80%. Recently, there has been little change in the supply side, maintaining a pattern of accumulated inventory. The supply-demand structure has improved narrowly, and there is a lack of substantial positive news in the periphery, resulting in a slightly insufficient market drive.
At the same time, the downstream polyester market has entered a low season of demand, with a production rate of around 86% and expectations of reduced output. Under the continuous weakening of demand, the focus of market transactions has shifted downwards, and the enthusiasm for raw material procurement is insufficient to maintain essential demand. Terminal textile enterprises have to alleviate capital turnover pressure by reducing production, coupled with a decrease in foreign trade orders, most of which focus on digesting inventory.
Business analysts believe that the narrow range of positive fluctuations in the crude oil market, but the overall weak performance of PTA supply and demand, will suppress the upward trend of PTA prices.

This week (July 14-18, 2025), the market for the main raw material of viscose staple fiber, dissolved pulp, remained stable, with average cost support. Various viscose staple fiber manufacturers still have a certain amount of finished product inventory, and the supply side performed well. Downstream yarn factories mainly executed a new round of orders, and the overall speed of goods in the market was weak and stable. The market price of viscose staple fiber was weak and slightly declined. In the future, attention should be paid to the follow-up of new orders from downstream yarn factories.
According to the Commodity Market Analysis System of Shengyi Society, as of July 18th, the average market price of viscose staple fiber was 12940 yuan/ton, a decrease of 80 yuan/ton from last week, with a weekly decline of 0.61%.
In terms of cost: This week (July 14-18, 2025), there has been little change in the market price of raw material dissolving pulp, with a weak stalemate. As of now, the price of domestically produced dissolving pulp is around 6700 yuan/ton, the price of outer broad-leaved pulp is around 800 US dollars/ton, and the price of coniferous pulp is around 870 US dollars/ton. The market prices of auxiliary materials such as liquid alkali and sulfuric acid remain stable but fluctuate slightly, with average cost support.
Abundant supply
Some adhesive short fiber units in Shandong region were shut down for maintenance at the end of last month, causing a decline in industry supply. Currently, the daily operating rate in the market remains at around 75%. Downstream yarn companies are picking up goods as needed, and the overall inventory of the adhesive short fiber market has decreased. However, the market supply is still abundant, and the positive support from the supply side is limited.
Downstream essential replenishment
The operating rate of downstream cotton yarn market equipment has slightly increased, and price fluctuations are not significant. As of now, the price of ring spun R30S in Jiangsu region is around 17100 yuan/ton, and the price of ring spun R40S is around 18300 yuan/ton. The market is in a traditional off-season of demand, and downstream cotton yarn market transactions are not ideal. Only a few models of vortex spun cotton yarn have slightly better export orders. Cotton mills mainly consume raw material inventory and replenish urgently needed goods, with no significant improvement in demand.
Future forecast
On the raw material side, the main material dissolution slurry market and the auxiliary material sulfuric acid market are generally stable, while the liquid alkali market may experience a narrow decline. Therefore, it is expected that the market price trend of adhesive short fiber raw materials will decline in the short term, and the cost support will be insufficient.
Supply and demand side: The operating rate of the adhesive short fiber market equipment may not fluctuate significantly, and some manufacturers have high inventory levels. Therefore, it is expected that the supply side support of the adhesive short fiber market will be poor in the short term; The terminal market is still in the traditional off-season of demand, with limited new orders placed. Downstream yarn mills are experiencing a certain degree of risk aversion and may maintain their demand for signing orders. It is expected that the driving force of the adhesive short fiber market from the demand side will be moderate in the short term.
Overall, the main raw material dissolution slurry market may be weak and stagnant, with sufficient overall supply. Downstream yarn mills mainly sign orders according to demand. Under the interweaving of on-site news, adhesive short fiber manufacturers may maintain their previous quotations. Therefore, analysts from Shengyi Society predict that the domestic adhesive short fiber market will remain stable with small movements in the short term, and the price is expected to be accepted at 12800-13000 yuan/ton.

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.
